The positive energy district (PED) is a rather recent concept that aims to contribute to the main objectives of the Energy Union strategy. It is based on an integrated multi-sectoral approach in response to Europe's most complex challenges. But to what extent have its development and implementation been supported by research and innovation programs? And what is the state of the art of its implementation and effective penetration into the current energy systems of European cities, according to the evidence provided by the scientific literature? This study aims to investigate these issues, providing a critical overview of the PED situation by means of a systematic literature review based on the use of open-access bibliometric software supplemented with content analysis. The results show that less than half of the documents analyzed refer to actual case studies, 80% of which were funded as part of research projects. This seems to lead to the conclusion that although PEDs have been strongly encouraged by the scientific community and policy initiatives at the European level, their implementation in cities is still limited. Moreover, an uneven distribution among countries can be observed. To overcome the existing barriers to PED diffusion and implementation, it would be useful to provide more ad hoc funding and, above all, facilitate its accessibility also by municipalities not yet well integrated into European projects, initiatives, and networks.

Climate Action Planning is one of the top priorities of cities in order to reduce greenhouse gas emissions and strengthening climate-resilience, as pointed out by the New Urban Agenda and the Paris Agreement. This study aims at assessing the development of climate change mitigation and adaptation planning in Italian cities. To this end, we analysed the availability of Local Climate Plans (LCPs) in 76 cities, which are included in the Eurostat Urban Audit (UA-2015) database. In a further step, we analysed the content of the urban climate change mitigation and adaptation plans available in a smaller sample of 32 Italian cities of 2007 Eurostat Urban Audit database (UA-3), looking at the single actions undertaken for addressing mitigation and adaptation to climate change. Results show the almost total absence of comprehensive and stand-alone urban climate change adaptation plans in Italy (except for two cities, Ancona and Bologna), whereas we found that in 61 out of 76 cities municipal civil protection plans are the instruments that deal with local emergencies associated to extreme weather events. On the other hand, 56 out of 76 urban climate change mitigation plans (i.e. Sustainable Energy Action Plans) are being developed in the framework of the Covenant of Mayors, which is a transnational network of local governments created by the European Union (EU) in 2012. The results obtained on the mitigation side point out that, in absence of a national law that imposes Italian cities to develop LCPs, transnational networks are an effective boost to voluntary commitment to reach EU climate and energy objectives. • The research shows a positive trend on urban climate change action in Italy. • Italian cities are more focused on mitigation than to adaptation. • Transnational networks have a crucial role in boosting climate planning in cities. • Cities need to adopt a more holistic approach in dealing with climate change. • More technical and financial resources are necessary to boost local climate actions.

Urbanization and the concentration of energy-consuming economic activities make cities responsible for more than 70% of global greenhouse gas emissions. At the same time, cities are becoming increasingly vulnerable to climate change impacts. The European Cities Mission launched a call in September 2021 to set out on a path towards "100 climate-neutral and smart cities by 2030". A very large and diverse sample of 344 candidate cities in 35 countries (a subset of the 362 considered eligible to participate in the Cities Mission) was used to conduct this timely research aimed at identifying the main dimensions on which cities are working to achieve a smart and sustainable transition. The research focused on five main dimensions: local climate planning, climate emergency declarations, participation in networks, international projects and competitions. Results show that only 20 (5.8%) cities have no experience in any of them, while there are 18 (5.2%) cities that have in their background activities that fall under all dimensions. Moreover, networking is the most important dimension, among the five analysed, for cities applying for this Mission, involving 309 cities (approximately 90% of the sample). This is followed by local climate planning, involving 275 cities (80%) and city participation in international projects, involving 152 cities (44%). Cities that have declared a climate emergency are less than a fifth of the sample and are very unevenly distributed in only 37.1% of the countries represented (interestingly, all the UK cities in the sample). Similarly, only 49 cities (14.2%) have received international awards. The results provide insights into the main efforts currently being made by cities to engage in the transition to climate neutrality and may be useful to practitioners, scholars and policy-makers at all levels to improve their knowledge of the steps they need to take to support this process and amplify its scope. [Display omitted] • Analysis of a subset (344) of candidate cities for the EU "Cities Mission". • Focus on climate plans, emergency declarations, networks, projects and awards. • Networking is the most important dimension, involving 90% of cities in the sample. • 80% of cities have a Local Climate Plan with targets for greenhouse gas reduction. • Climate emergency declarations in 18.4% of cities: UK leads with 100% of cities.

This study investigates the climate emergency declaration (CED) movement in cities and its effects and synergies with local climate planning. Urban areas are experiencing a wide range of climate-induced extreme events, particularly those located in the Mediterranean hotspot. The focus is on Italian cities, which have only recently become key players in climate planning. The method is based on the collection, analysis, and comparison of data on CEDs and local climate plans (LCPs), integrated with information on city membership in climate networks, to extrapolate key performance indicators of the CED movement. The results show that the CED movement can motivate municipalities to become more ambitious in climate action. As of February 2021, the "climate emergency" movement was supported by 105 Italian cities geographically concentrated in the northern regions (66.7%). The motivation behind a CED is often attributable to local populations calling for concrete climate action (91.1% referred to the Fridays for Future movement) but also to a greater perception of the impacts of climate change (85.6% referred to the Special Report on Global Warming of 1.5 °C). Networking plays an important role (85 cities in the Covenant of Mayors). Interestingly, 36 cities (34.3%) were not engaged in local climate planning previously, but the CED shows now they see the urgency to act. 24.4% cities aim at carbon neutrality in their CEDs (most with local adaptation aspirations), with a much smaller fraction of cities doing so in LCPs and generally lower ambition in terms of greenhouse gas emission reduction targets. [Display omitted] • Case study: 105 IT cities that have declared climate emergency (66.7% in the north). • Motivation: 91.1% refer to the FFF movement, 85.6% to the 2018 IPCC Special Report. • Networking: 85 cities are members of CoM and 33 of the Italian Green City Network. • 34.3% of the CED cities had not previously a mitigation or adaptation plan. • 24.4% of CEDs aim at carbon neutrality, while LCPs have less ambitious GHG targets.

The role of cities and their commitment to meet the European targets on energy and climate has steadily increased in the latest years as testified by the large number of ambitious initiatives undertaken by European cities to face multiple challenges towards sustainability. Many projects and initiatives have arisen all around Europe to support cities in the achievement of the Europe 2020 targets of smart, sustainable and inclusive growth. RE-SEEties “Towards resource-efficient urban communities in SEE” is one of the projects funded under the South East Europe program aimed to enhance the policy-making and strategic planning competences of municipalities in the field of energy efficiency, renewable energy sources and waste valorization. This paper focuses on the methods developed and the main results achieved in the framework of RE-SEEties. The main focus is on the eight partner cities (The Local Government of Budapest District 18 – Hungary/HU, Municipality of Aigaleo – Greece/EL, Municipality of Potenza – Italy/IT, City of Nitra – Slovakia/SK, City of Skopje – Former Yugoslav Republic of Macedonia/FYROM, City of Miercurea Ciuc – Romania/RO, Municipality of Ptuj – Slovenia/SI, City of Ivanić-Grad – Croatia/HR) and how they were assisted by professional institutions in translating their commitments towards resource efficiency into Local Strategies and Action Plans. A critical comparison of these final results points out differences and similarities in the state-of-the-art of cities across South East Europe as well as a the level of ambition and difficulties faced to turn into resource efficient urban communities.

Translating resource efficiency into practical European, national and local policy frameworks which integrate the various economic, social and environmental components passes through short to long term visions, strategies as well as measurable targets. The RE-SEEties project was funded by the South East Europe programme in order to contribute to the resource efficiency challenge. The project investigated on energy consumption and waste production and disposal; potential changes in consumption patterns and how policy making alternatives may support the achievement of resource efficiency targets. This paper aims to present the main results of this unique international cooperative experience carried out by research centres and municipalities in the South East Europe area. First, the paper focuses on the methodological toolkit and criteria for assessment which aims to support municipalities in creating a sustainable and resource efficient future through coherent and appropriate planning practices. Second, the paper discusses the main results obtained and lessons learned on a wide range of interrelated issues covering the policymaking process, financing of local resource-efficiency investments, good practices, tools to support decision-making and assessment methodologies. It also covers behavioural change and how policy can stimulate public authorities, companies and citizens to become more sustainable. [ABSTRACT FROM AUTHOR]

In Europe, regions in the Mediterranean area share common characteristics in terms of high sensitivity to climate change impacts. Does this translate into specificities regarding climate action that could arise from these Mediterranean characteristics? This paper sheds light on regional and local climate mitigation actions of the Mediterranean Europe, focusing on the plans to reduce greenhouse gases emissions in a representative sample of 51 regions and 73 cities across 9 Mediterranean countries (Croatia, Cyprus, France, Greece, Italy, Malta, Portugal, Slovenia, Spain). The study investigates: (i) the availability of local and regional mitigation plans, (ii) their goals in term of greenhouse gas emissions reduction targets on the short and medium-long term, and (iii) the impact of transnational climate networks on such local and regional climate mitigation planning. Results of this study indicate an uneven and fragmented planning, that shows a Mediterranean West-East divide, and a link with population size. However, overall, both regional and city action seem insufficiently ambitious with regards to meeting the Paris Agreement, at least at city level. While national frameworks are currently weak in influencing regional and local actions, transnational networks seem to be engaging factors for commitment (at city level) and ambitiousness (at regional level). The uneven and fragmented progress revealed by this study, does not align with the characteristics shared by investigated regions and cities in terms of environmental, socio-political, climatic and economic conditions. The results support the call of a common green deal at the Mediterranean level to further address specific Mediterranean challenges and related needs. This will allow to capitalise on available resources, generate local-specific knowledge, build capacities, and support Mediterranean regions and cities in preparing the next generation of more ambitious mitigation plans. [Display omitted] • Analysis of mitigation plans of 51 regions and 73 cities in Mediterranean Europe. • Uneven progress, with West-East divide and a generally modest short-term ambition. • Bigger size Mediterranean regions and cities show higher climate action. • Mitigation planning is affected by national regulation and transnational networks. • There is a case for cross-border cooperation among Mediterranean regions and cities.

As recognized by the Paris Climate Agreement of the United Nations Framework Convention on Climate Change (UNFCCC), local and subnational regions are crucial actors to achieve international mitigation and adaptation commitments. Scientific literature and empirical evidence point at multi-level climate governance as a crucial factor to engage subnational levels in the achievement of national and international objectives. This work focuses on the multi-level climate governance arrangements in Italy to investigate how Italian regions/provinces/cities are contributing to the achievement of national commitments. To this purpose, the paper undertakes a review of the climate policies of different tiers of government adopted to date and of the interrelationships among them. The results of the analysis show that the effective coordination between the different government levels should be strengthened to further incentivize and support initiatives at the local level. Results also show the relevant role played by international regional and city climate networks in boosting local and regional climate planning in Italy. • Climate plans of 21 Italian regions, 32 provinces, and 32 cities were assessed. • 57% of the Italian regions; 13% of provinces and 78% of cities set a carbon target. • 10% of regions, no province, and 2% of municipalities have an adaptation plan. • Cities are more active than provinces and regions in defining mitigation policies. • Active multilevel governance is effective for implementing climate plans in cities.

Cities across the globe recognise their role in climate mitigation and are acting to reduce carbon emissions. Knowing whether cities set ambitious climate and energy targets is critical for determining their contribution towards the global 1.5 °C target, partly because it helps to identify areas where further action is necessary. This paper presents a comparative analysis of the mitigation targets of 327 European cities, as declared in their local climate plans. The sample encompasses over 25% of the EU population and includes cities of all sizes across all Member States, plus the UK. The study analyses whether the type of plan, city size, membership of climate networks, and its regional location are associated with different levels of mitigation ambition. Results reveal that 78% of the cities have a GHG emissions reduction target. However, with an average target of 47%, European cities are not on track to reach the Paris Agreement: they need to roughly double their ambitions and efforts. Some cities are ambitious, e.g. 25% of our sample (81) aim to reach carbon neutrality, with the earliest target date being 2020.90% of these cities are members of the Climate Alliance and 75% of the Covenant of Mayors. City size is the strongest predictor for carbon neutrality, whilst climate network(s) membership, combining adaptation and mitigation into a single strategy, and local motivation also play a role. The methods, data, results and analysis of this study can serve as a reference and baseline for tracking climate mitigation ambitions across European and global cities. • 78% of cities have a mitigation plan with targets (avg. 47% GHG reduction). • Only 25% of cities strive for carbon neutrality, most by 2050, avg. By 2045. • 90% of cities striving for carbon neutrality are members of a climate network. • Ambition is driven by city size, climate networks, M-A combination, local motivation. • European cities must double their ambitions to meet the aims set by the Paris Agreement.

Making public buildings smarter and more energy efficient requires tailored solutions to overcome the barriers in implementing suitable technology options in a large variety of building types. The PrioritEE project aimed to strengthen the policy-making and strategic planning competencies of local and regional public authorities in the energy management of Municipal Public Buildings, gaining experience in five local pilots in the Mediterranean area. This paper focuses on the PrioritEE toolbox, describing both the "soft components" and the technical components. These components are widely applicable and replicable in all European cities for supporting local administrations in improving energy efficiency and the use of renewable energy sources in municipal public buildings. The Energy Technologies and Building Retrofit Database is a technology repository of energy efficiency measures and renewable energy technologies, providing the main reference data on costs, technical performance and lifetime. With the Decision Support Tool users can assess current building stock energy performance, evaluate different efficiency and renewable interventions, and compare, rank, and prioritize technical options through a set of key performance indicators. A sample of the results to date in the five partner regions are also presented, comparing the main individual characteristics in order to derive replicable solutions for local authorities. This project also highlighted how crucial stakeholder involvement is for tool improvement, capacity building and enabling knowledge transfer. • A new toolbox widely applicable to foster energy efficiency and renewable energies. • A decision support tool to compare and prioritize different energy interventions. • Capacity-building for local energy management of municipal public buildings. • Stakeholder involvement is crucial to improve tools and develop local action plans. • Living Labs are very useful to engage people and promote energy conscious behaviour.

This paper investigates the energy system of the Basilicata region (southern Italy) to highlight, through a scenario analysis, its possible future development in compliance with the European Commission's long-term vision. The IEA-ETSAP methodology was utilized to model and analyse the Basilicata energy system in a business- as -usual scenario, based on the assumptions of the 2010 Regional Energy and Environmental Policy Plan, and in two low-carbon scenarios, decarbonisation and high energy efficiency, which, in line with the long-term European strategy, foresee an 85% carbon dioxide emission reduction and a 20% energy efficiency increase in 2050. The results highlight that electricity production from renewable energy sources (in particular wind energy), strongly supported by the regional policy, goes beyond the Basilicata Regional Energy-Environmental Plan forecast, with a further increase in the decarbonisation scenarios. In addition, solar thermal and highly efficient technologies are adopted in commercial and residential end-use sectors. An additional 9% reduction in energy consumption is achieved in the high energy efficiency scenario by passive houses. The proposed approach shows the usefulness of a modelling framework typically used for national and supranational analyses to support regional authorities in their decision-making process to obtain results in line with the European and national strategies. Application to the Basilicata region shows the usefulness of a consolidated framework for policy assessment at a local scale to assess regional contribution to the achievement of national climate mitigation targets that tend towards climate neutrality. • The role of regional authorities is essential to reach national decarbonisation goals. • TIMES can be advantageously used for regional energy system modelling and analysis. • Scenario analysis can be a powerful tool for policy evaluation. • A cap on carbon dioxide emissions leads to a 28% increase of electricity production. • Passive houses in Residential allow a further 5% reduction of energy consumption.

Energy consumption can be significantly reduced by targeting consumers behaviour to achieve sustained energy savings and promote sustainable consumption patterns. In this context, the younger generations are a privileged target group to promote virtuous energy behaviours in the whole community. This paper describes the Schools4energy initiative, a program developed within the Interreg MED PrioritEE project, aimed at increasing energy efficiency in municipal public buildings by raising energy awareness in public schools while demonstrating the effectiveness of pupils' engagement to promote energy savings through virtuous behaviours. Schools4energy was based on a multifold "learning by doing" methodology implemented in the Living Lab of the Potenza case study. During the 2018/2019 school year, children aged between 3 and 14 belonging to four primary and middle schools owned by the Municipality of Potenza (Southern Italy) were involved in three sets of activities designed to valorise the power of young generation in promoting more conscious behaviours: a competition among schools to reduce energy consumption (School Race) based on the adoption of good energy practices based on a common Energy Charter, an artistic competition among students to support creative thinking (Art4energy) and gamification as an alternative method to learn about energy (Play4energy). The consumptions of natural gas and electricity were monitored from August 2018 to April 2019 to highlight the effects of the adoption of Energy Charter in terms of energy and money saved. Data analysis highlighted different trends among the participating schools, underlining their different commitment and the infrastructural barriers. Despite the harsher winter, an average decrease of 4% in natural gas consumption was observed in the school in which energy saving measures complemented technical interventions and a limited increase in electricity consumption (between 0.5% and 4.3% per capita), which led to savings on the energy bill of about 1122 Euro. The enthusiastic participation of the children highlighted the great potential of educational programmes in driving a steady change of mentality in the society. Image 1 • A Living Lab was developed to boost energy saving in public schools. • A "learning by doing" method to raise energy awareness was implemented. • School competition encourages all schools' occupants to save energy. • Virtuous energy behaviours are learned at school and brought back to homes. • The best result is a 4% reduction of gas and a slight increase in electricity (0.5%).

Cities across Mediterranean Europe face common climatic threats. They are highly vulnerable and very likely to suffer losses and damages due to heat waves, droughts, wildfires, landslides, and extreme coastal events. To this date, however, there is no systematic understanding of how cities in Mediterranean Europe are preparing to adapt to these impacts. To address this question, we analyse local adaptation plans in 73 cities located in 51 regions across 9 European countries along the Mediterranean Sea (France, Italy, Spain, Greece, Portugal, Croatia, Slovenia, Cyprus and Malta). We also investigate upper levels of planning to understand the influence of policy environments. Across the sample, 67 % of regions have adopted a plan, but only 30 % of the cities. The most common climate-related hazards these cities prepare for are extreme temperatures and rainfall, followed by drought and water scarcity, as well as floods and landslides. Without legal obligations, neither regional nor national adaptation policy frameworks seem to influence the development of urban plans. In some cases, cities are ahead of national policy. This paper sheds light on the progress of local adaptation planning in Mediterranean Europe and paves the way for further research in this climate-threatened geographical area. [Display omitted] • ME faces severe climate hazards, faster and stronger than global averages. • We analyse adaptation plans in 73 cities across 51 regions and 9 ME countries. • 30 % of cities and 67 % of regions in Mediterranean Europe have adaptation plans. • Regions plan more for adaptation when action plans from national governments are in place. • Common concerns are urban temperature and rainfall, drought, and water scarcity.

The Paris Agreement aims to limit global mean temperature rise this century to well below 2 °C above pre-industrial levels. This target has wide-ranging implications for Europe and its cities, which are the source of substantial greenhouse gas emissions. This paper reports the state of local planning for climate change by collecting and analysing information about local climate mitigation and adaptation plans across 885 urban areas of the EU-28. A typology and framework for analysis was developed that classifies local climate plans in terms of their alignment with spatial (local, national and international) and other climate related policies. Out of eight types of local climate plans identified in total we document three types of stand-alone local climate plans classified as type A1 (autonomously produced plans), A2 (plans produced to comply with national regulations) or A3 (plans developed for international climate networks). There is wide variation among countries in the prevalence of local climate plans, with generally more plans developed by central and northern European cities. Approximately 66% of EU cities have a type A1, A2, or A3 mitigation plan, 26% an adaptation plan, and 17% a joint adaptation and mitigation plan, while about 33% lack any form of stand-alone local climate plan (i.e. what we classify as A1, A2, A3 plans). Mitigation plans are more numerous than adaptation plans, but planning for mitigation does not always precede planning for adaptation. Our analysis reveals that city size, national legislation, and international networks can influence the development of local climate plans. We found that size does matter as about 80% of the cities with above 500,000 inhabitants have a comprehensive and stand-alone mitigation and/or an adaptation plan (A1). Cities in four countries with national climate legislation (A2), i.e. Denmark, France, Slovakia and the United Kingdom, are nearly twice as likely to produce local mitigation plans, and five times more likely to produce local adaptation plans, compared to cities in countries without such legislation. A1 and A2 mitigation plans are particularly numerous in Denmark, Poland, Germany, and Finland; while A1 and A2 adaptation plans are prevalent in Denmark, Finland, UK and France. The integration of adaptation and mitigation is country-specific and can mainly be observed in two countries where local climate plans are compulsory, i.e. France and the UK. Finally, local climate plans produced for international climate networks (A3) are mostly found in the many countries where autonomous (type A1) plans are less common. This is the most comprehensive analysis of local climate planning to date. The findings are of international importance as they will inform and support decision-making towards climate planning and policy development at national, EU and global level being based on the most comprehensive and up-to-date knowledge of local climate planning available to date.

The evidence of relationships between climate change induced by greenhouse gases of anthropogenic origin, and energy-economic issues (inappropriate use of fossil fuels and technologies, uncertainty in fuels price and demand trends, etc.) asks for the adoption of a holistic approach in order to re-orient the anthropogenic activities’ system towards a configuration that harmonizes environmental protection, economic growth and security of energy supply. In this framework, energy system sustainability represents one of the major challenge the EU is facing and its implementation passes through a path of coordinate actions carried out by local governments in which objectives of sustainable development become integral part of strategic programming. The aim of this research is to provide local administrations with an analytical support tool to guide key strategic decisions in energy and climate planning on the medium-long term, assessing the possible role of local energy systems in the achievement of sustainable objectives at national/European scale. This paper focuses on the implementation of a partial equilibrium TIMES-generated model in a real case study, the regional energy system of Basilicata region (Southern Italy). First, it describes the adopted methodology. Second, it is provided a step-by-step description and characterisation of the reference energy system and the model’s data input which represents the first step for an in-depth knowledge of the present energy system on which to build effective and sustainable local energy and climate plans.
