• Temperature and precipitation anomalies are key drivers of within-country inequality. • Agriculture is a fundamental channel in the climate change-inequality nexus. • Warmer temperatures have a stronger impact on income disparities in rural countries. • Urban areas are more exposed to income disparities induced by extreme precipitations. • Inward FDI diversification enhances resilience, moderating climate-induced inequality. This paper investigates the impact of climate change on within-country income inequality for more than 150 nations over the period 2003–2017. Specifically, we control for a large number of determinants of income disparities detected by extant literature and focus on agriculture as one of the most crucial channels in the climate change-inequality nexus. We find that temperature increases and precipitation anomalies have significant adverse effects on within-country inequality, especially in the presence of larger shares of population in rural areas and of workers in agriculture. We also provide evidence on the lower distributional impact of climate change in economies that are more diversified across value chain activities. [ABSTRACT FROM AUTHOR]

The mitigation of greenhouse gas concentration has become a first-order issue for decision making in environmental sustainability. Countries can meet their mitigation commitments and environmental objectives through multiple instruments. A key role is played by cooperative mechanisms, such as the Clean Development Mechanism (CDM), under the Kyoto Protocol, and a similar mechanism established by the Paris Agreement (Art. 6), whose implementation rules are still under negotiation. However, another form of cooperation was already established under the different framework of the Official Development Assistance (ODA), potentially sharing abatement purposes. This paper aims to compare the mitigation actions implemented either as CDM or ODA projects. We conduct a multi-criteria econometric analysis, based on an originally created, harmonised dataset that merges renewable energy CDM projects and comparable ODA projects to investigate the role of the institutional framework in influencing the effectiveness of reducing emissions worldwide. Results show that the Kyoto Protocol had a positive impact in terms of cost-effectiveness for renewable energy projects and that it stimulated policy actions for environmental sustainability. Accordingly, in view of the implementation of Article 6 of the Paris Agreement, it is extremely important both to look to the past to draw lessons from Kyoto's successes and failures and to apply multi-criteria decision-making approaches for the design of environmental policies. c• We create an original harmonised dataset that merges CDM and comparable ODA projects. • We move from qualitative considerations to a quantitative econometric analysis of CDM-ODA. • CDM renewable projects are more advantageous in terms of cost effectiveness compared to ODA. • The different institutional frameworks play a crucial role on the performance of the two cooperative instruments. • For the implementation of Art.6 of the Paris Agreement, it is important to learn from Kyoto's successes and failures.

In a scenario characterised by mitigation concerns and calls for greater resilience in the energy sector, energy audits (EAs) emerge as an essential mean for enhancing end-use energy consumption awareness and efficiency. Such a tool allows us to assess the different energy carriers consumed in a productive sector, offering insight into existing energy efficiency improvement opportunities. This opens avenues for research to devise an econometrics-based methodology that encapsulate production sites and their environmental essentials. This paper contributes to the literature by exploiting the EAs received by the Italian National agency for New technologies, Energy, and Sustainable Economic Development (ENEA) in 2019 from the Italian plastics manufacturing sector, matched with Italian firm-based data extracted from the Analisi Informatizzata delle Aziende Italiane (Italian company information and business intelligence) (AIDA) database. In particular, we investigate how the implementation of energy efficiency measures (EEMs) is influenced by a set of contextual factors, as well as features relating to the companies and EEMs themselves. The empirical investigation focuses on the EAs submitted to ENEA in 2019, which was strategically chosen due to its unique data availability and adequacy for extensive analysis. The selection of 2019 is justified as it constitutes the second mandatory reporting period for energy audits, in contrast to the 2022 data, which are currently undergoing detailed refinement. In line with the literature, the adopted empirical approach involves the use of both the OLS and logistic regression models. Empirical results confirm the relevance of economic and financial factors in guiding the decisions surrounding the sector's energy performance, alongside the analogous influence of the technical characteristics of the measures themselves and of the firms' strategies. In particular, the OLS model with no fixed effects shows that a one-percent variation in investments is associated with an increase in savings performance equal to 0.63%. As for the OLS model, including fixed effects, the elasticity among the two variables concerned reaches 0.87%, while in the logistic regression, if the investment carried out by the production sites increases, the expected percentage change in the probability that the energy-saving performance is above its average is about 187.77%. Contextual factors that prove to be equally influential include the incentive mechanism considered and the traits of the geographical area in which the companies are located. Relevant policy implications derived from this analysis include the importance of reducing informational barriers about EEMs and increasing technical assistance, which can be crucial for identifying and implementing effective energy solutions.

• EU countries are classified in four groups based on energy efficiency trajectories. • Domestic energy systems co-evolve with innovation system and policy mix. • Structural change and export competitiveness are affected by the systems co-evolution. • Positive spillovers arise between countries with similar policy mix and high trade relations. • International knowledge and policy spillovers lead to high innovative and competitiveness performances. This paper aims to analyse the evolution of energy efficiency systems for the residential sector of EU countries over the past twenty years and the associated process of structural change occurred in EU economies. To this purpose, we develop a set of indicators to measure some significant characteristics of the energy efficiency systems focusing on the residential sector and map European countries in terms of four dimensions: energy system, innovation pattern, policy mix design and export competitiveness. Building on these indicators we develop a cluster analysis identifying non-arbitrary homogeneous country groups according to several characteristics in order to investigate the co-evolution of technological trajectories, energy use performance and export competitiveness in this specific domain. Results suggest the distinction of EU countries into four groups, that are individually and comparatively scrutinized shedding light on how the four dimensions here considered dynamically evolved and interacted within and across countries. Empirical findings suggest that the design of the domestic policy mix may influence technological trajectories and structural change processes. Such effect appears to be related to the quality and dimension of international relationships with main economic partners. [ABSTRACT FROM AUTHOR]

While socioeconomic and institutional factors are crucial in explaining the onset and evolution of conflicts, recent research suggests that climate change is a further indirect driver acting as a "threat multiplier". This paper focuses on the concept of vulnerability to both climate change and conflicts to explain why some locations are more likely to engage in armed conflicts than others in the presence of a similar level of exposure to climatic changes. In particular, by means of a Spatial Autoregressive Model, we identify a set of local-specific vulnerability factors that increase conflict risk in East Africa. We employ a georeferenced database with a resolution of 25 × 25 km, covering the period 1997–2016. Results from our analysis provide some interesting insights: first, climate change does not increase conflict risk per se , but only in the presence of pre-existing vulnerabilities. Second, resource access and socioeconomic factors play a key role in driving the climate-conflict nexus especially in urban areas. In particular, vulnerability is increased whenever power is not distributed in such a way as to ensure an equitable distribution of resources. Overall, our findings suggest that, by addressing vulnerability factors that prevent adaptive capacity and an equitable distribution of resources, societies may benefit in terms of both diminished conflict risk and alleviation of climate change impacts. • The climate-conflict nexus is mediated by access to resources at the local level. • Climate change only increases conflict risk in case of pre-existing vulnerabilities. • Climate change acts as a threat multiplier for vulnerable communities. • Synergies for ensuring adaptive capacity to climate change and peace exist.

The introduction and adoption of green technologies are considered the most cost effective way to reduce environmental pressure without compromising economic competitiveness. The scientific literature has emphasized the crucial role played by diffusion pathways of green technologies along the supply value chain, but empirical quantitative findings on the effectiveness of green technologies in improving environmental performance are scarce. The objective of this paper is to highlight the role of inter-sectoral linkages in shaping the influence played by eco-innovations on sectoral environmental performance. Empirical findings show that both the direct and indirect effects of eco-innovations help reducing environmental stress and that the strength of these impacts varies across the value chain depending on the technology adopted and the type of pollutant under scrutiny. The main implications we can deduce are that, first both corporate and policy governance strategies should specifically address the goal of maximizing environmental gains that can be achieved through the development and adoption of clean technologies along the supply chain, and second both strategies should be coordinated in order to minimize the costs for reducing environmental pressures.

The European Union (EU) has developed a strategy to mitigate climate change by cutting greenhouse gas (GHG) emissions and fostering low carbon technologies. However, the risk of implementing unilateral policies is that distortive effects are generated at the global scale affecting world energy prices, international competitiveness and the geographical allocation of carbon intensive production processes. Using a dynamic CGE model, we assess the rate of carbon leakage and adverse impacts on competitiveness in a number of scenarios over the period 2010–2050. According to the model results, we highlight two major issues. First, in the case of a unilateral EU climate policy, carbon leakage and negative effects on competitiveness are quite serious. Anti-leakage measures can only mitigate leakage and adverse economic impacts on competitiveness in a limited way. On the contrary, an optimality analysis addressing the environmental effectiveness, cost-effectiveness and political feasibility of alternative policy solutions reveals that the EU long term decarbonisation strategy by investing in energy efficiency and renewable energy might ensure protection of vulnerable manufacturing activities while enhancing the competitiveness of technologically-advanced industries.
