The purpose of this I Special Issue on Access and Allocation in Earth System Governance i is to undertake a decadal analysis of the literature on the subject since 2008, to harvest lessons learnt, to test some of these ideas and to develop theories on governance. Although they apply the access and allocation lens to adaptation, they argue that these terms are less intuitive for the adaptation literature and prefer the notion of climate justice. The final synthesis paper by Gupta and Lebel argues that although in some fields access and allocation may appear to be unintuitive terms, this paired framework enables unpacking socio-ecological justice issues.

Guidance for supporting individuals with climate distress often lacks a theoretical foundation to account for its social dimension. This paper argues for the value of the social identity approach (SIA) for understanding and supporting individuals with climate distress in clinic. Three aspects of climate distress are considered: social isolation, collective emotions, and climate action. It is posited that the SIA can guide interventions in a way that is tailored to the specific social dynamics entailed in each client's climate distress. The paper also considers how clinicians can weigh up the potential advantages and disadvantages of interventions that are commonly advised for these individuals, such as contact with nature and engaging in collective action. The author is a clinical psychologist and lecturer researching climate distress. [ABSTRACT FROM AUTHOR]

This paper seeks to address Nigeria's challenges in meeting its climate objectives by investigating feasible pathways that can be implemented to accelerate progress and ensure credibility in meeting these targets. By examining the current policies and practices in place as well as successful strategies employed by other countries, this paper aims to provide strategies and policy implications recommendations for Nigeria to enhance its climate action efforts. The potential scenarios developed in this study ranged from increasing renewable energy capacity to implementing stricter regulations and standards for industries to reduce their carbon footprint, promote sustainable production processes, and strengthen climate governance and policy frameworks. The authors further investigated these measures and discovered that implementing stricter regulations and standards for industries would reduce their carbon footprint, promote sustainable production processes, and strengthen climate governance and policy frameworks. As such, Nigeria will be able to meet its climate goals more quickly as a result of the following factors: preventing environmental degradation, funding environmentally friendly infrastructure, and improving public transportation systems that can reduce vehicle-related greenhouse gas emissions. The authors developed policy measures based on the proposed twelve credible pathways to catching up with climate goals in Nigeria, thereby promoting faster progress by the Nigerian government in achieving climate goals. By adopting these measures, Nigeria's progress toward the proposed zero net by 2060 will be significantly accelerated. It will position Nigeria as a continental leader in sustainable development and contribute to the overall global efforts to mitigate climate change. This will not only benefit the environment but also lead to financial development and an improved standard of living for its citizens. [ABSTRACT FROM AUTHOR]

The growth of the gardening kit market could result in the increased wasting of nursery pots, which are usually made of plastic. Replacing these pots with biodegradable pots made from green waste could have benefits for climate mitigation, the circular economy, and the greenness of gardening. To address this, we introduce a prototype recycled waste leaf litter (RWLL) nursery pot. Via an incubation experiment over 90 d, we examined their biodegradability and effects on microbial enzyme activity and inorganic nitrogen concentration, comparing them with commercially available biodegradable pots, namely peat–paper mixture pots (also known as Jiffypots®) and coco-coir pots. The effects of pot thickness were tested. Based on mass loss during incubation and on soil CO2 efflux, the RWLL pots exhibited excellent biodegradability, regardless of their thickness, with decomposition rates and soil CO2 efflux 1.5–6 times greater than other biodegradable pots. Biodegradability, extracellular enzyme activity, and soil inorganic nitrogen content were not affected by RWLL pot thickness or by the presence or absence of a plant in the soil. Unlike in natural ecosystems, leaf litter is treated as waste in urban green spaces, and its decomposition into soil organic matter is prevented. Creating plant pots from leaf litter enhances soil quality, reduces atmospheric carbon emissions, and satisfies the desire of gardeners for greenness. [ABSTRACT FROM AUTHOR]

Fruit tree improvement has taken great strides by roping in improved and efficient biotechnological tools to increase fruit yield and quality to meet local and export demands. For the past decade, the RNA-Seq tool has successfully been used in fruit tree improvement programs to identify genes, dissect complex traits, and understand different molecular pathways and differential expression of genes. However, despite their growing importance in food and nutrition security, medicinal uses, and climate change mitigation strategies, very little has been done to improve the pomological traits of African indigenous fruits, especially at the molecular level. African indigenous fruit trees exhibit unexplained variation in flowering, fruit load, fruit size, fruit ripening, fruit taste, fruit nutritional composition and shelf-life. The booming local commercial companies and export markets are demanding consistent quality indigenous fruits. This has necessitated the need for fast and effective tools that will hasten the understanding and improvement of fruiting qualities. The improvement of fruiting and fruit qualities will go a long way in accelerating the domestication and commercialization of African indigenous fruit trees. This review paper gives molecular biology insights on how RNA-Seq has been successfully used in fruit improvement of exotic fruits through gene identification, comparative transcriptome analysis under different conditions, and understanding molecular pathways that influence important pomological traits. The review article also unearths opportunities where RNA-Seq can improve our knowledge and improvement of undesirable traits common in African indigenous fruits. [ABSTRACT FROM AUTHOR]

Although ambitious, forest landscape restoration (FLR) is still very high on global climate change mitigation and adaptation research and policy agendas. The scientific literature highlights the importance of institutions and actors' collaboration for achieving the intended outcomes. Despite these diffuse indications, a comprehensive understanding of the role played by different types of actors and institutions in shaping FLR outcomes is missing. This hinders the definition of an actor-cum-institutions research agenda for FLR, especially in sub-Saharan Africa (SSA). Yet, in this region, different actors with diverse interests shape FLR practices. Likewise, formal and informal institutions are known to collide frequently. Hence, this paper addresses the lacunae by systematically reviewing FLR actors' interests and power manifestations and the typologies of institutions linked to FLR outcomes in SSA. The review further defines future research agendas on actors and institutions in SSA. The following lessons can be drawn from the review of 75 peer-reviewed journal articles: First, while exogenous actors are interested more in the ecological benefits of FLR, endogenous actors are interested in economic ones. Second, exogenous actors mostly use (dis-)incentives and coercion to shape the behavior of endogenous actors in FLR. Finally, while the exogenous formal institutional typology produces positive and negative ecological, economic, political, and sociocultural FLR outcomes, the endogenous formal and informal institutions produce only positive outcomes. Future studies should identify actors' compliance levels of the exogenous and endogenous formal and informal typologies of institutions. Future studies should also analyze the effectiveness of FLR-linked institutions towards ensuring successful FLR. [ABSTRACT FROM AUTHOR]

This paper studies early arguments in Sweden for combating climate change. We show how scientific results in relation to climate change entered the political sphere as part of the debate on energy in the 1970s, a process we propose to name energysation. We argue that the use of climate science by pro-nuclear political actors served as a way of maintaining a course set by a high-energy society while simultaneously trying to outmanoeuvre the growing environmental anti-nuclear and low-energy movement. When the pro-nuclear power side met with resistance, this led to a displacement of climate change knowledge away from the realm of the national political sphere and specific energy forms, a process we conceptualise as de-energysation. By highlighting conflicts and the political framings of climate change in the early years 1974-1983, we suggest that the history of these frames influences current delay in climate change mitigation and limits the range of actions and ways of addressing the ongoing climate emergency.

The cities of the world have been the exploiters of resources and the largest generators of waste. This paper explores the concept of Ecological Urbanism as a framework to convert cities from being waste generators to resource producers. The example of the wastewater from Bengaluru going into the lakes of Kolar is studied. The treated wastewater of the city reaches Kolar to fill its lakes, which subsequently recharges the groundwater. One city's waste becomes another's resource in this process. The case of Kolar-Bengaluru is studied while asking critical questions of urban-rural planning with ecology as a main premise. [ABSTRACT FROM AUTHOR]

Cities and urban areas are one of the critical global systems that can accelerate and upscale climate action and more than ever need to achieve the 11 goals of Agenda 2030 becoming inclusive, safe, resilient and sustainable. In 2019, Science published a paper suggesting that planting trees, on a massive scale and sustained period of time, represented one of the most effective solutions at our disposal to mitigate climate change. Cities across the world have started implementing urban forests to address multiple environmental issues. Urban forests are capable to provide more complete solutions than other urban NBS. In this context, the challenge for cities is to disseminate UF-NBS throughout the city in order to release environmental and social benefits even in the most dense areas, spreading wellbeing for all citizens. The paper illustrates a cutting-edge experimentation of a tiny forestation action at the neighborhood scale, aimed at integrating both regulative and social-cultural ecosystem services. In line with the principles of the UN Agenda 2030, the Eco-Pedagogical Microforest project, that took place in Rome, demonstrates that even a small patch of nature can increase young people's biospheric values, influencing pro-environmental behaviors and actions, enhancing wellbeing.

Laboratory experiments were conducted to investigate the effects of water vapor on the reaction of nitric oxide with ozone in a chemiluminescence instrument used for fast response and high sensitivity detection of atmospheric ozone. Water vapor was introduced into a constant level ozone standard and both ozone and water vapor signals were recorded at 10 Hz. The presence of water vapor was found to reduce, i.e. quench the ozone signal. A correction factor was determined to be 4.15±0.14×10-3, which corresponds to a 4.15% increase in the measured ozone signal per 10 mmolmol-1 cosampled water vapor. An ozone-inert water vapor permeable membrane (Nafion dryer) was installed in the sampling line and was shown to remove the bulk of the water vapor mole fraction in the sample air. At water vapor mole fractions above 25 mmolmol-1, the Nafion dryer removed over 75% of the water vapor in the sample. This reduced the ozone signal correction from over 11% to less than 2.5 %. The Nafion dryer was highly effective at reducing the fast fluctuations of the water vapor signal (more than 97 %) while leaving the ozone signal unaffected, which is a crucial improvement for minimizing the interference of water vapor fluxes on the ozone flux determination by the eddy covariance technique.

The face of climate action is increasingly young, well informed, and active. But despite the growing rumble of this youth-quake, the New Zealand political system has to date been slow to respond to climate change mitigation. This article will therefore critically explore the apparent paradox between the image of New Zealand as a leading progressive democratic society, and its current response to the climate emergency. In particular, the paper will interrogate this theme from the perspectives of the international critique of New Zealand's current legal and policy response, the dynamic lens of climate change litigation and its potential to influence public policy, and the increasing impact of tikanga Māori as a primary source of New Zealand law and its relational approach to the wellbeing of the environment and the underlying ethic of stewardship. The overall thesis of the paper will be that cumulatively these trends will have the energy to generate an effective response to climate change and mobilise the urgent joined-up action required to reduce greenhouse gas emissions and build adaptive capacity within the closing opportunity of the next two decades.

Humanity is challenged with making progress toward global biodiversity, freshwater, and climate goals, while providing food and nutritional security for everyone. Our current food and land-use systems are incompatible with this ambition making them unsustainable. Papers in this special feature introduce a participatory, integrated modeling approach applied to provide insights on how to transform food and land-use systems to sustainable trajectories in 12 countries: Argentina, Australia, Canada, China, Germany, Finland, India, Mexico, Rwanda, Sweden, the UK, and USA. Papers are based on work completed by members of the Food, Agriculture, Biodiversity, Land-use, and Energy (FABLE) initiative, a network of in-country research teams engaging policymakers and other local stakeholders to co-develop future food and land-use scenarios and modeling their national and global sustainability impacts. Here, we discuss the key leverage points, methodological advances, and multi-sector engagement strategies presented and applied in this collection of work to set countries and our planet on course for achieving food security, biodiversity, freshwater, and climate targets by 2050.

This paper addresses the macroeconomic challenges stemming from the double affectedness of climate change and dependence on external finance in peripheral countries. The paper uses the Post-Keynesian concept of an asset's own rate of return to assess how susceptibility to the combined effects of erratic capital flows and the vulnerability vis-à-vis the physical and transitional risks of climate change reduces macroeconomic policy space. Climate change and mitigation strategies are said to contribute to financial instability ensuing flight-to-quality of international investors. This translates into higher external financial fragility in low income countries with a high degree of commodity dependence—with increased exchange rate volatility and devaluating pressure deteriorating affected countries' currencies' liquidity premia and the expectation of their short-term exchange rates as result. Consequently, policy-makers in affected countries are forced to commit to investor-friendly policies and high interest rates to uphold their currencies' acceptance. The susceptibility to the physical risks of climate change and mitigation hence contributes to the self-perpetuating nature of international monetary asymmetries and hierarchies.

The climate change – inequality nexus has become an increasingly important concept advanced by inequality and sustainability experts as well as international organisations like the United Nations. In this perspective paper, two arguments are made to further our understanding of the nexus and to promote action on SDG 10 ("Reducing inequalities within and among countries") and SDG 13 ("Climate action"). First, climate change's status as a "core" planetary boundary as well as its embeddedness in the 2030 Agenda for Sustainable Development, calls for a wider discussion on environmental and ecological degradation in the context of inequality. Second, the concept of inequalities of opportunity freedoms, under the guise of the influential human capabilities framework, is well suited to make sense of the complexity and multidimensionality of the climate change – inequality nexus. To this end, some (and by no means all) causal links between climate change, wider environmental and ecological degradations, and inequality are analysed. The paper concludes by arguing in favour of a framework that can aptly capture the full complexity and multidimensionality of the climate change – inequality nexus. [ABSTRACT FROM AUTHOR]

As the carrier of global urbanization, urban land is the basic means of productivity and life of urban residents. Urban land management is of great significance to global climate change mitigation, improving ecological quality, promoting economic development, and ensuring sustainable urban development. At present, although studies on urban land management have accumulated at the global level, the differences in research methods, objectives, and perspectives have led to the fragmentation and confusion of research conclusions. Therefore, it is necessary to review the literature of urban land management, clarify the research contexts, grasp the research progress, and predict the research trends. Bibliometrics, as a quantitative analysis method of literature review analysis, is more comprehensive and objective than relying only on a literature review. It is of great value to grasp the topics and trends of the research field from an overall perspective. In this paper, the Bibliometrix R software package was used to conduct an econometric literature analysis on urban land management from 1979 to 2021, using the Web of Science database. The results showed that: (1) the annual scientific research output and citation frequency in the field of urban land management has generally increased. Combined with the annual change trend of scientific research output, urban land management research can be divided into three stages: the budding period, from 1979 to 1989, the development period, from 1990 to 2008, and the high-yield period, from 2009 to 2021. (2) The 129 countries/regions reviewed differed in their research output, and developed countries showed strong research. The United States, China, and Australia were the top three countries in terms of solo publications and cooperation publications. In addition, among the 16,270 authors, the top three authors were Pradhan, Zhao, and Li. (3) The top three keywords in the field of urban land management were "Management", "City/Cities" and "Land Use". The research topics can be divided into three stages. The first stage covers studies with topics of "Management", "Urbanization" and "GIS", from 1979 to 2013. From 2014 to 2018, the research topics were gradually enriched by "Urbanization", "Impact", "System", "GIS", "Management", "Policy", "Conservation" and "land", with a trend towards multidisciplinary and multi-perspective comprehensive analyses. From 2019 to 2021, "Management" and "Climate Change" were the main topics. [ABSTRACT FROM AUTHOR]

Coastal wetlands are significant components of the coastal landscape with important roles in ecosystem service provision and mitigation of climate change. They are also likely to be the system most impacted by climate change, feeling the effects of sea levels rise, temperature increases and rainfall regime changes. Climate change impacts on estuarine coastal wetlands (mangroves, saltmarsh) have been thoroughly investigated; however, the impacts on coastal freshwater wetlands (CFWs) are relatively unknown. To explore the current knowledge of the impacts of climate change on CFWs globally, we undertook a systematic quantitative literature review of peer-reviewed published literature. We found surprisingly little research (110 papers of an initial 678), the majority of which was conducted in the USA, focusing on the effects of sea level rise (SLR) on CFW vegetation or sediment accretion processes. From this research, we know that SLR will lead to reduced productivity, reduced regeneration, and increased mortality in CFW vegetation but little is known regarding the effects of other climate change drivers. Sediment accretion is also not sufficient to keep pace with SLR in many CFWs and again the effects of other climate drivers have not been investigated. The combination of unhealthy vegetation communities and minimal gain in vertical elevation can result in a transition towards a vegetation community of salt-tolerant species but more research is required to understand this process.

This is a commentary on the paper in GCB by Moinet et al. (2023) entitled "Carbon for soils, not soils for carbon". The paper challenges two claims often made for soil carbon sequestration: (1) Sequestration of C in agricultural soils can make a substantial contribution to climate change mitigation. (2) Increasing SOC will routinely lead to increased crop yields and contribute to global food security. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to clarify the CO2 emissions of global construction industries under the consideration of different patterns of international trade and thus to draw a comprehensive picture for understanding the international paths of CO2 transfer to global construction industries. Design/methodology/approach: This research inventories the CO2 emissions induced by the final demand of 15 economies for construction products and explores the CO2 intensities of these economies based on a multi-regional input–output model. This paper further decomposes CO2 emissions into four components based on different patterns of international trade to estimate the roles of four patterns of international trade in shaping the environmental pressures from global construction industries. Findings: The results indicate that the CO2 intensities of the construction industries in Russia, India and China were higher than those in other economies, and the CO2 intensities of global construction industries experienced a decline over the years 2000–2014. The decomposition analysis demonstrates that domestic and foreign CO2 emissions accounted for 42.67 and 54.23%, respectively, of the CO2 emissions of the construction industries in the 15 economies during the period 2000–2007. Although the major part of the CO2 emissions of the construction industries come from domestic production systems, the final demand for construction products in the 15 economies caused substantial emissions in other economies. Further decomposition by upstream industrial production source indicates that 58.65% of domestic emissions and 66.53% of foreign emissions can be traced back to the electricity industry. Research limitations/implications: Although the major patterns of CO2 emissions of the construction industry have been identified in this paper, the difficulty of understanding the relationship between upstream production industries or countries and the construction industry deserves more attention in the future research. Originality/value: Previous research on inventorying CO2 emissions has generally been limited to evaluating the impact of industrial consumption activities on national or global emission accounting, tending to ignore the effects of different international trade patterns on the change in industrial CO2 emissions. This research is the first attempt to account for and decompose the CO2 emissions of global construction industries under consideration of the effects of different patterns of international trade on environmental pressures. The decomposition and upstream industrial distributions of different patterns of CO2 emission provide a comprehensive picture for better understanding of the emission pattern and source of the CO2 emissions of global construction industries. The research outcomes reveal how the final demand of a country for construction products induces CO2 emissions in both domestic and foreign systems, thus providing basic information and references for policy adjustment and strategy design in relation to mitigation of climate change and sustainable development.

Forests are subject to a huge variety of often competing socio-economic demands and environmental change. This paper assesses the related conflicts that occur along what we label to be a "Global Forest Environmental Frontier". Assessing 11 contributions to a special issue on the same topic, it summarizes the main contents of these papers and concludes with an assessment of major trends. The contributions to the special issue take both a regional and topic-related approach, assessing forest environmental conflicts on all five forested continents and investigating issues such as forest biodiversity conservation, climate change adaptation and mitigation, environmental justice and equity, development, and forest management and conservation discourses. Taken together, they provide an overview on the multiple facets of the Global Forest Environmental Frontier, but also identify some shared patterns and trajectories, which are outlined at the end of this paper.

The Earth is currently undergoing a sixth global‐scale ecological crisis. The most recent Intergovernmental Panel on Climate Change (IPCC) report of 2021 highlighted a need to curb global heating at 1.5 degrees above the pre‐industrial baseline, and outlined a range of likely impacts of climate change on global societies should no action be taken, particularly in relation to reducing greenhouse gas emissions to net zero by 2050. Despite this need, policy‐based action at a nation state level is lacking, with talks at COP25 failing to reach necessary agreements. In response to this, and as we approach COP26, a significant global youth movement has been activated, with children and young people taking it upon themselves to highlight a need for climate and environmental action, calling for others to follow. This paper follows the emotional journey of one of its co‐authors, 11‐year‐old environmental activist, Lucie. Through the innovative approach of co‐production with Lucie, in this paper we detail the role of emotion in one youth activist's journey. From her initial reactions watching BBC's Blue Planet II, to the multifaceted highs and lows that have followed as she strives for change, we illuminate the emotional implications such experiences may have on children and young people.

This paper presents a comprehensive analysis of the suitability of nuclear power as an option to combat the escalating climate emergency. Summarizing and evaluating key arguments, we elucidate why nuclear power is unsuitable for addressing climate change. The primary argument centers around the unresolved technical and human risks of accidents and proliferation, which are unlikely to be effectively mitigated in the future. Furthermore, we highlight the significant cost disparities between nuclear power and other non-fossil energy sources, such as solar photovoltaics and wind power, considering levelized costs of electricity. We also address the incompatibility of nuclear power with renewable energy systems, emphasizing the need for flexibility in the face of variable solar and wind resources. Alternative reactor technologies will not be available in time to make a major contribution. Nuclear power also poses challenges in power plant operation amid climate change and war. Ultimately, we argue that other motivations should be explored to explain the continued interest in nuclear power in some countries, as energy supply arguments alone are insufficient to justify new investments.

In the context of increasingly severe global climate change, finding effective carbon emission reduction strategies has become key to mitigating climate change. Environmental Protection Tax (EPT), as a widely recognized method, effectively promotes climate change mitigation by encouraging emission reduction behaviors and promoting the application of clean technologies. Based on data from 282 cities in China, this paper takes the official implementation of the EPT in 2018 as the policy impact and the cities with increased tax rates for air taxable pollutants as the treatment group and uses DID model to systematically demonstrate the relationship between the implementation of the EPT and carbon intensity (CI) and further explores the possible pollutant emissions and green innovation mediating effects. The findings show that (1) the implementation of EPT can effectively reduce CI by about 4.75%, and this conclusion still holds after considering the robustness of variable selection bias, elimination of other normal effects, policy setting time bias, and self-selection bias. (2) The implementation of EPT can reduce CI by reducing pollutant emissions and improving the level of green innovation. (3) There is obvious regional heterogeneity in the carbon reduction effect of EPT, and the implementation of EPT has a more significant effect on CI in medium-tax areas, low environmental concern areas, general cities, and eastern regions. This paper not only provides a new analytical perspective for systematically understanding the carbon emission reduction effect of EPT but also provides policy insights for promoting regional green transformation and advancing carbon peak carbon neutralization.

As the atmospheric carbon dioxide (CO2) concentration rapidly rises, carbon capture, utilization, and storage (CCUS) is an emerging field for climate change mitigation. Various carbon capture technologies are in development with the help of adsorbents, membranes, solvent-based systems, etc. One of the main challenges in this field is the removal of CO2 from nitrogen (N2) gas. This paper focuses on mixed matrix membrane technology, for which the CO2/N2 separation performance is based on differences in gas permeations. Membrane separation and purification technologies are widely studied for carbon capture. Microporous adsorbents such as zeolites and metal organic frameworks (MOFs) for carbon capture have been attracting researchers' attention due to their highly porous structures, high selectivity values, and tunable porosities. Utilizing microporous adsorbents dispersed within a novel, blended polymer matrix, fourteen membranes were prepared with the commercial MOF ZIF-8, zeolite 13X, and kaolin, with methyl cellulose (MC) and polyvinyl alcohol (PVA), which were tested using a single gas permeation setup in this study. The addition of polyallylamine (PAH) as a chemisorbent was also investigated. These membranes were synthesized both with and without a polyacrylonitrile (PAN) support to compare their performances. MC was found to be an ideal polymeric matrix component to develop free-standing MMMs. At 24 °C and a relatively low feed pressure of 2.36 atm, a free-standing zeolite-13X-based membrane (MC/PAH/13X/PVA) exhibited the highest N2/CO2 selectivity of 2.8, with a very high N2 permeability of 6.9 × 107 Barrer. Upon the optimization of active layer thickness and filler weight percentages, this easily fabricated free-standing MMM made of readily available materials is a promising candidate for CO2 purification through nitrogen removal.

Carbon capture and storage (CCS) is a critical technology for mitigating greenhouse gas emissions and combating climate change. CCS involves capturing CO2 emissions from industrial processes and power plants and injecting them deep underground for long-term storage. The success of CCS projects is influenced by various factors, including the regional pressure dissipation effects in subsurface geological formations. The safe and efficient operation of CCS projects depends on maintaining the pressure in the storage formation. Regional pressure dissipation, often resulting from the permeability and geomechanical properties of the storage site, can have significant effects on project integrity. This paper provides a state-of-art of the impact of regional pressure dissipation on CCS projects, highlights its effects, and discusses ongoing investigations in this area based on different case studies. The results corroborate the idea that the Sleipner project has considerable lateral hydraulic connectivity, which is evidenced by pressure increase ranging from <0.1 MPa in case of an uncompartmentalized reservoir to >1 MPa in case of substantial flow barriers. After five years of injection, pore pressures in the water leg of a gas reservoir have increased from 18 MPa to 30 MPa at Salah project, resulting in a 2 cm surface uplift. Furthermore, artificial CO2 injection was simulated numerically for 30 years timespan in the depleted oil reservoir of Jurong, located near the Huangqiao CO2-oil reservoir. The maximum amount of CO2 injected into a single well could reach 5.43 × 106 tons, potentially increasing the formation pressure by up to 9.5 MPa. In conclusion, regional pressure dissipation is a critical factor in the implementation of CCS projects. Its impact can affect project safety, efficiency, and environmental sustainability. Ongoing research and investigations are essential to improve our understanding of this phenomenon and develop strategies to mitigate its effects, ultimately advancing the success of CCS as a climate change mitigation solution.

Appropriately designed and implemented climate mitigation actions have multiple co-benefits (yet some trade-offs cannot be excluded) that result in substantial social and economic value beyond their direct impact on reducing energy consumption and GHG emissions. Despite their wider acknowledgement by the research community, decision makers and the public have incomplete information on these multiple effects. This paper has a twofold objective: First, through analytical bottom-up approaches, it assesses, in quantitative terms, the macroeconomic effects and the public health benefits attributed to a variety of mitigation actions under consideration in the context of the Greek Energy and Climate Plan. Second, it investigates, through a social survey, how citizens perceive climate change and value these multiple impacts of mitigation actions, and to what extent they are willing to pay for them and support the adoption of policy measures aiming at the green transition of the Greek economy. We show that mitigation actions bring about significant health benefits, particularly in cities, and generate significant positive macroeconomic effects, particularly if mitigation actions focus on the decarbonization of the building sector and on the exploitation of local renewable sources. We also argue that most people do not realize that climate mitigation actions can have wider benefits for society, such as tackling energy poverty, improving public health, and creating new jobs. Unwillingness to pay tends to be the prominent attitude. People who are more reluctant to cover a part of the cost of environmental protection are less likely to perceive that climate change is one of the main challenges at global and national level and support the adoption of climate mitigation policies. In this context, the national strategy for climate change should focus on effectively informing and engaging the public in climate mitigation strategies, strengthening the public trust in government institutions, promoting mutually acceptable solutions with the local communities, and providing incentives for changing citizens' behavior towards climate-related actions.

The aim of this policy paper is to characterize the current situation of Tunisian municipalities in matters of climate change policies and actions and to understand the barriers and best practices. By surveying municipalities in Tunisia, we were able to provide an overview of the Tunisian municipalities in matters of climate change actions and strategies, as well as finding the main barriers and best practices. First, we found that most Tunisian municipalities are facing different effects of climate change. Second, the majority of municipalities do not have a strategy for mitigation and adaptation of climate change at the local level. Third, the main barrier that municipalities face in investing in climate change actions is the lack of financial resources and funding. Four, we have identified some of the best climate change mitigation and adaptation practices of surveyed cities, which should be taken into consideration and implemented also by the other cities.

Contemporary cities are facing many challenges, from social and economic issues to the new risks related to the impacts of climate change. Focusing on energy consumptions, and the related GHG emissions, cities are considered not only the main global contributors but also the areas most exposed to risks, because of their density of population and economic activities. Implementing urban planning strategies with the purpose of increasing energy efficiency and resilience overall, is, for all these reasons, considered a top priority. This paper investigates the innovative content related to the energy-efficient and energy-resilient urban planning solutions that have started to be implemented in the cities of the Emilia-Romagna region. Two kinds of planning instruments are therefore analysed: the voluntary Sustainable Energy and Climate Action Plans (SECAPs) and the mandatory General Urban Plans (GUPs), recently approved in several cities of Emilia-Romagna. A comparative analysis of three cities in the Emilia-Romagna region, Bologna, Modena, and Ravenna is proposed, looking at the strategies of their new local city plans and SECAPs with a focus on energy management and planning. The aim is to assess whether the new structure of local city plans and the influence of SECAPs could be useful in implementing such urban-energy resiliency solutions. [ABSTRACT FROM AUTHOR]

This paper examines how global climate mitigation policies articulate with urban political–ecological transformations. It focuses on South African waste-to-value projects as case studies, exploring how local processes of urban ecological modernization combine with global climate finance through the now largely defunct Clean Development Mechanism (CDM). Whilst it is generally recognized that waste-related CDM projects in South Africa (and elsewhere) have been an unmitigated failure in terms of climate and socio-economic benefits, we demonstrate that landfill-to-gas/energy projects have functioned effectively as geographical–discursive dispositifs through which particular knowledge systems are enrolled, specific 'solutions' are projected, and singular imaginaries of what is possible and desirable foregrounded, thereby crowding out alternative possibilities. This not only nurtures the commodification and marketization of non-human matter with an eye towards sustaining capital accumulation but, rather more importantly, successfully installs state-orchestrated private property relations around common resources, thereby deepening the dispossessing socio-ecological relations upon which expanded capitalist reproduction rests. We argue that whilst the formal outcome of the CDM is a failure, its success resides precisely in how it permitted local and global elites to create administrative and regulatory practices that solidify and naturalize a neoliberal market-based framework to approach the climate crisis.

Purpose: This study aims to explore when and under what conditions state-owned enterprises (SOEs) become important players in orchestrating the global climate action and what their roles are as domestic or international (de)carbonizers. Design/methodology/approach: This is a conceptual paper that aims to advance understanding of the role of SOEs in addressing the global climate challenge. The authors build on the institutional theory to capture the importance of home-country climate regulation mechanisms and advance knowledge on the internationalization of SOEs. The authors review the literature on the institutional boundaries that shape the environmental activities of firms at home and abroad and develop the argument on the influence of home country institutions and internationalization on the role of SOEs in the global climate agenda. Findings: In this study, the authors elaborate the SOEs' climate action matrix and offer three propositions based on the fact that SOEs' environmental strategies are driven by the interests of the state as owner and the scope of SOEs' internationalization. First, the authors propose that the level of home country's climate policy ambition explains SOEs' stance on climate action. Second, scope of internationalization explains SOEs' stance on climate action. Third, the progressive/increasing involvement of SOEs in climate action enhances the country's climate stance. Originality/value: The authors incorporate the climate argument into international business (IB) studies of SOEs' internationalization, a novel approach that helps us to advance the knowledge on the complex issue of corporate climate action. The authors argue for a dynamic and reciprocal relationship between home/host countries and SOEs' climate engagement. In doing this, the authors contribute to the IB research and policy agenda by exploring SOEs' engagement in advancing the global climate agenda. [ABSTRACT FROM AUTHOR]

Flood hazard and risk assessments (FHRAs), and the underlying models, form the basis of decisions regarding flood mitigation and climate adaptation measures and are thus imperative for safeguarding communities from the devastating consequences of flood events. In this perspective paper, we discuss how FHRAs should be validated to be fit-for-purpose in order to optimally support decision-making. We argue that current validation approaches focus on technical issues, with insufficient consideration of the context in which decisions are made. To address this issue, we propose a novel validation framework for FHRAs, structured in a three-level hierarchy: process-based, outcome-based, and impact-based. Our framework adds crucial dimensions to current validation approaches, such as the need to understand the possible impacts on society when the assessment has large errors. It further emphasizes the essential role of stakeholder participation, objectivity, and verifiability when assessing flood hazard and risk. Using the example of flood emergency management, we discuss how the proposed framework can be implemented. Although we have developed the framework for flooding, our ideas are also applicable to assessing risk caused by other types of natural hazards. [ABSTRACT FROM AUTHOR]

Engineering biology (EngBio) is a dynamic field that uses gene editing, synthesis, assembly, and engineering to design new or modified biological systems. EngBio applications could make a significant contribution to achieving net zero greenhouse gas emissions. Yet, policy support will be needed if EngBio is to fulfil its climate mitigation potential. What form should such policies take, and what EngBio applications should they target? This paper reviews EngBio's potential climate contributions to assist policymakers shape regulations and target resources and, in so doing, to facilitate democratic deliberation on desirable futures. Engineering biology is a dynamic field that uses gene editing, synthesis, assembly, and engineering to design new or modified biological systems. Here the authors discuss the policy considerations and interventions needed to support a role for engineering biology in climate change mitigation. [ABSTRACT FROM AUTHOR]

Restoring tree cover changes albedo, which is the fraction of sunlight reflected from the Earth's surface. In most locations, these changes in albedo offset or even negate the carbon removal benefits with the latter leading to global warming. Previous efforts to quantify the global climate mitigation benefit of restoring tree cover have not accounted robustly for albedo given a lack of spatially explicit data. Here we produce maps that show that carbon-only estimates may be up to 81% too high. While dryland and boreal settings have especially severe albedo offsets, it is possible to find places that provide net-positive climate mitigation benefits in all biomes. We further find that on-the-ground projects are concentrated in these more climate-positive locations, but that the majority still face at least a 20% albedo offset. Thus, strategically deploying restoration of tree cover for maximum climate benefit requires accounting for albedo change and we provide the tools to do so. Restoring tree cover is a prominent climate solution but can cause global warming due to changes in albedo. This paper maps albedo and carbon changes from restoring tree cover to highlight where the greatest net climate benefits can be achieved. [ABSTRACT FROM AUTHOR]

Green hydrogen, produced by water electrolysis with renewable energy, plays a crucial role in the revolution towards energy sustainability, and it is considered a key source of clean energy and efficient storage. Its ability to address the intermittency of renewable sources and its potential to decarbonize sectors that are difficult to electrify make it a strategic component in climate change mitigation. By using a method based on a bibliometric review of scientific publications, this paper represents a significant contribution to the emerging field of research on green hydrogen and provides a detailed review of electrolyzer technologies, identifying key areas for future research and technology development. The results reflect the immaturity of a technology which advances with different technical advancements, waiting to find the optimal technical solution that allows for its massive implementation as a source of green hydrogen generation. According to the results found in this article, alkaline (ALK) and proton exchange membrane (PEM) electrolyzers seem to be the ones that interest the scientific community the most. Similarly, in terms of regional analysis, Europe is clearly committed to green hydrogen, in view of the analysis of its scientific results on materials and electrolyzer capacity forecasts for 2030.

The natural hazards caused by climate change have a significant impact on the production and life of urban residents, enhancing urban resilience is an important way to cope with climate disasters and ensure the safety of urban systems. Based on the "urban resilience" research relevant literature, the paper applies bibliometric analysis software to reveal the research hotspots and evolution trends of urban resilience in the perspective of climate change. The results indicate that the main research contents can be summarized into four aspects: i) influencing factors of urban resilience; ii) evaluation index and method of urban resilience; iii) the impact of climate change on urban resilience; iv) Enhancing urban resilience in response to climate change. Finally, potential directions for future research on urban resilience were proposed, multi-dimensional research on urban resilience should be carried out from aspects of theoretical development, urban planning based on resilience mechanisms should be carried out from the perspective of planning practice, and innovation and reform should be carried out in policy implementation and urban management. Accurately understanding the conceptual connotation and construction mechanism of urban resilience is a crucial premise for climate mitigation and adaptation. Relevant research conclusions can provide useful reference for theoretical research and spatial planning of resilient cities. [ABSTRACT FROM AUTHOR]

One significant obstacle to gaining a widespread awareness of the ongoing climate change is the nature of its manifestations in relation to our perception: climate change effects are gradual, distributed, and sometimes seemingly contradictory. These features result in a lag in collective climate action and sometimes foster climate skepticism and climate denial. While the literature on climate change perception and belief has thoroughly explored its sociocultural and sociopolitical aspects, research on the potential contribution of psychophysiological factors remains scarce. In this perspective paper, we outline evidence and arguments for the involvement of psychophysiological systems such as thermoception, hygroreception, and interoception in modulating climate change awareness. We discuss psychophysiological mechanisms of climate change awareness in animals and humans, as well as possible sources of individual variance in climate change perception. We conclude by suggesting novel research questions which would be worthwhile to pursue in future studies. [ABSTRACT FROM AUTHOR]

This article examines the perspectives of low- and middle-income countries (LMICs) on climate change mitigation and fossil fuel supply within the UN framework convention on climate change (UNFCCC). Achieving the temperature targets of the Paris Agreement requires leaving fossil fuels underground (LFFU), which presents challenges for LMICs due to their significant fossil fuel reserves. This dilemma raises equity concerns as these countries must balance climate action with their Right to Development (RtD). Against this background, through a content analysis of documents submitted to the UNFCCC and triangulation with ownership structures of extraction projects, this paper explores how ten LMICs define their roles in addressing climate change and LFFU, with a focus on mitigation policies and the energy sector. Drawing on Gramscian concepts such as hegemony, common sense, historical bloc, war of position, passive revolution, and trasformismo, this paper presents a non-exhaustive neo-Gramscian perspective for the analysis of supply-side climate policy in developing countries. The analysis reveals that LMICs' development paths have been characterized by fossil fuel expansion, energy addition, and carbon lock-in, grounded on energy security reasons, export dependencies, or equity and responsibility. From these findings, the paper argues that the global energy transition can be interpreted as a passive revolution: the fossil historical bloc, through the interdependencies between states, national oil companies, and fossil capital, maintains its hegemonic position by aligning material, organizational, and discursive resources around fossil fuels, with the RtD serving as a discursive tool to perpetuate fossil dominance in energy systems, agreeing to the legitimate demands for development. One of the trasformist tactics deployed is the bridge narrative of gas, which accommodates and neutralizes the challenge posed by renewables. Nonetheless, there are opportunities for Southern leadership to contest the bloc with potential counter-hegemony. This paper contributes to the ongoing debate on supply-side mitigation policies and distributive justice issues in the North–South context, focusing on the need and potential for an inclusive and just energy transformation. There are avenues of research to analyse how the challengers' war of position will bear fruit in coalition building and the establishment of a new, just, and inclusive common sense.

Dryland farming is at the center of increasing pressure to produce more food for the growing population in an environment that is highly variable and with high expectations for the standard of their production systems. While there is mounting pressure for increased productivity, the responsibility to protect the environment and diminish the agricultural sector's carbon footprint is receiving growing emphasis. Achieving these two goals calls for a consolidated effort to ensure that the scientific community and service providers partner with farmers to create a sustainable food production system that does not harm the environment. In this paper, we studied the nature of the services present in the market and identified ways that could be used to improve the climate services available to the agricultural sector. Important factors that could increase the usability of climate services include coproduction, context-specific information, innovation, demand-driven services, timeliness of services, highly applicable information, provision of services in the correct format, services that increase user experience, specificity of services to a locale, and services that are easily accessible.

Climate change is a complex issue with significant scientific and socio-economic uncertainties, making it difficult to assess the effectiveness of climate policies. Dynamic Integrated Climate-Economy Models (DICE models) have been widely used to evaluate the impact of different climate policies. However, since climate change, long-term economic development, and their interactions are highly uncertain, an accurate assessment of investments in climate change mitigation requires appropriate consideration of climatic and economic uncertainties. Moreover, the results of these models are highly dependent on input parameters and assumptions, which can have significant uncertainties. To accurately assess the impact of climate policies, it is crucial to incorporate uncertainties into these models. In this paper, we explore the impact of parameter uncertainties on the evaluation of climate policies using DICE models. Our goal is to understand whether uncertainty significantly affects decision-making, particularly in global warming policy decisions. By integrating climatic and economic uncertainties into the DICE model, we seek to identify the cumulative impact of uncertainty on climate change. Overall, this paper aims to contribute to a better understanding of the challenges associated with evaluating climate policies using DICE models, and to inform the development of more effective policy measures to address the urgent challenge of climate change.

After describing how the marine environment is tottering in the face of the triple environmental crisis, this article explores the limited governance progressions at the global and regional levels in addressing the threats of pollution, climate change and biodiversity loss in the especially vulnerable Arctic. For pollution, key limitations include slow and arduous processes to add chemicals for control under the Stockholm and Rotterdam Conventions and reliance at the regional level on a fragmented array of pollution studies and projects but without specific region-wide legally binding pollution standards. For climate change, the world is not on track to meet the Paris Agreement's temperature targets which is especially problematic for the Arctic cryosphere while the Arctic Council has largely been limited to providing general statements of concern and aspirational calls for enhanced climate mitigation and adaptation actions. For marine biodiversity losses, a pan-Arctic network of marine protected areas has yet to be developed and various implementation challenges surround the Agreement to Prevent Unregulated High Seas Fisheries in the Central Arctic Ocean including the need to ensure adequate financial, human resource and technical support. The paper concludes by highlighting some promising future governance directions. They include: the conclusion of a global treaty on plastic pollution; implementation of a new Global Framework on Chemicals – For a Planet Free of Harm from Chemicals and Waste; expected further clarifications from international tribunals on State responsibilities to address climate change; and regional implementation of the Kunming-Montreal Global Biodiversity Framework and the new agreement under the UN Convention on Law of the Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction.

The purpose of this research is to investigate the thermal impact of urban green systems (UGS) (trees and living facades) and high albedo pavements on reducing the urban heat island (UHI) effect in London at the pedestrian street level. The research assesses the impact of UGS by suggesting practicable urban greenery-covering densities (25% and 50%) and using high albedo pavement in current and future climatic scenarios (2050 and 2080). This approach is intended to encourage pedestrians to walk longer distances for longer durations during the warmer months, following the Transport for London's (TfL) 2017 Healthy Streets initiative. The research seeks to measure the advantages and assess the possible impact on the comfort and activities within urban streets. The study adopts a quantitative research design using ENVI-met modelling and questionnaires. Simulation results, the subject of this paper, confirmed that, across three climatic scenarios, the optimal UGS for thermal comfort is 50% trees followed by 25% trees, dependent on street orientation and solar access. Living facades (LF) with 25% and 50% covering had no discernible effect on the comfort of pedestrians, whereas high albedo pavement increases heat stress. [ABSTRACT FROM AUTHOR]
