Building back better: Granular energy technologies in green recovery funding programs

Summary Granular energy technologies with smaller unit sizes and costs deploy faster, create more jobs, and distribute benefits more widely than lumpy large-scale alternatives. These characteristics of granularity align with the aims of fiscal stimulus in response to COVID-19. We analyze the technological granularity of 93 green recovery funding programs in France, Germany, South Korea, and the UK that target £72.9 billion for low-carbon energy technologies and infrastructures across five emissions-intensive sectors. We find that South Korea's "New Deal” program is the most technologically granular with strong weighting toward distributed renewables, smart technologies, electric vehicle charge points, and other relatively low unit cost technologies that are quick to deploy. The UK has the least granular portfolio, concentrating large amounts of public money on small numbers of mega-scale energy projects with high implementation risks. We demonstrate how technological granularity has multiple desirable characteristics of green recovery: jobs, speed, and distributed benefits.

Can We Detect Urban‐Scale CO2 Emission Changes Within Medium‐Sized Cities?

The COVID‐19 pandemic resulted in a widespread lockdown during the spring of 2020. Measurements collected on a light rail system in the Salt Lake Valley (SLV), combined with observations from the Utah Urban Carbon Dioxide Network observed a notable decrease in urban CO2 concentrations during the spring of 2020 relative to previous years. These decreases coincided with a ∼30% reduction in average traffic volume. CO2 measurements across the SLV were used within a Bayesian inverse model to spatially allocate anthropogenic emission reductions for the first COVID‐19 lockdown. The inverse model was first used to constrain anthropogenic emissions for the previous year (2019) to provide the best possible estimate of emissions for 2020, before accounting for emission reductions observed during the COVID‐19 lockdown. The posterior emissions for 2019 were then used as the prior emission estimate for the 2020 COVID‐19 lockdown analysis. Results from the inverse analysis suggest that the SLV observed a 20% decrease in afternoon CO2 emissions from March to April 2020 (−90.5 tC hr−1). The largest reductions in CO2 emissions were centered over the northern part of the valley (downtown Salt Lake City), near major roadways, and potentially at industrial point sources. These results demonstrate that CO2 monitoring networks can track reductions in CO2 emissions even in medium‐sized cities like Salt Lake City.Alternate :Plain Language SummaryHigh‐density measurements of CO2 were combined with a statistical model to estimate emission reductions across Salt Lake City during the COVID‐19 lockdown. Reduced traffic throughout the COVID‐19 lockdown was likely the primary driver behind lower CO2 emissions in Salt Lake City. There was also evidence that industrial‐based emission sources may of had an observable decrease in CO2 emissions during the lockdown. Finally, this analysis suggests that high‐density CO2 monitoring networks could be used to track progress toward decarbonization in the future.

Stakeholder engagement and decarbonization pathways: Meeting the challenges of the COVID-19 pandemic

Climate change is an extremely complex challenge characterized by its systemic nature and deep uncertainties. Thus, finding solutions requires a continuing and constructive dialogue between the research community and a wide range of stakeholders from governments, non-governmental organizations, civil society, international organizations, industry, businesses and financial institutions. The ENGAGE project (https://www.engage-climate.org/) is advancing knowledge co-production through an iterative process of stakeholder engagement with two main streams: (i) stakeholder co-design and assessment of global decarbonization pathways and (ii) stakeholder dialogues on national policies and pathways. Both the global and national stakeholder processes are designed to inform multiple project activities, including: conceptualization of feasibility and assessing the feasibility of decarbonization policies and strategies;decarbonization pathway development using integrated assessment models and considering both feasibility and equity;and assessment of the relative importance of climate change impacts vis-à-vis potential co-benefits. With the start of the COVID-19 pandemic 6 months after the beginning of the project, all of the stakeholder engagement activities had to be organized as online events. Between March 2020 and April 2022, 5 online workshops were organized, two at the global level and 3 at the regional/national level. This paper documents how the challenges of effectively engaging stakeholders in a co-design and dialogue process in an online setting have been met through a process of evaluation and learning that led to the introduction of new approaches and tools to support an inclusive exploration and development of low-carbon transition pathways. We show that a combination of interactive visualizations, open channel surveys and moderated breakout groups are particularly useful tools for online stakeholder engagement. The learning that has taken place through the use of these tools is demonstrated with reference to both the research team (e.g., learning about stakeholders' views on the feasibility of decarbonization pathways) and the stakeholders (e.g., learning about experiences in other countries in dealing with the challenges of decarbonization). The results of using these tools have been used within the project in the design of new decarbonization pathways using integrated assessment models, in the development of a framework for feasibility assessment and in increased attention to socio-economic drivers of change. We conclude that despite several advantages of online engagement, such as the expanded geographical coverage and reduced CO2 emissions, the need to keep online meetings short means that important elements of face-to-face meetings cannot be included. Online activities cannot completely replace physical meetings when dealing with complex issues such as climate change.

Analysis of the European Strategy for Hydrogen: A Comprehensive Review

This review focuses on analysing the strategy and aspirations of the European Union within the hydrogen sector. This aim is achieved through the examination of the European Parliament's hydrogen strategy, allowing for a study of actions and projects in hydrogen technologies. The Parliament's hydrogen strategy is the document that provides the guideline of how the EU intends to function in the hydrogen sector and manages to cover a wide range of topics, all of them significant to represent the entirety of the hydrogen sector. It touches on subjects such as hydrogen demand, infrastructure, research, and standards, among others. The review discusses also the aspect that the EU intends to be a leader in the hydrogen sector, including the large-scale industrialization of key elements such as electrolysers, and this purpose is corroborated by the large number of associations, strategies, plans, and projects that are being established and developed by the European Union. The most important conclusions to learn from this analysis are that hydrogen has many of the right characteristics to make it the key to decarbonisation, especially in hard-to-abate sectors, and that it is bound to be one of the main actors in the imminent green transition. Moreover, hydrogen seems to be having its breakthrough, and this field's development can have benefits not only from an environmental perspective but also from an economical one, enabling the way into the green transition and the fight against climate change.

Performance of Equity Investments in Sustainable Environmental Markets

Despite a significant increase in global clean energy investments, as part of the decarbonization process, it remains insufficient to meet the demand for energy services in a sustainable manner. This study investigates the performance of sustainable energy equity investments, with focus on environmental markets, using monthly equity index data from 31 August 2009 to 30 December 2022. The main contributions of our study are (i) assessment of the performance of trading strategies based on the trend, momentum, and volatility of Environmental Opportunities (EO) and Environmental Technologies (ET) equity indices;and (ii) comparison of the performance of sustainable equity index investments to fossil fuel-based and major global equity indices. Market performance evaluation based on technical analysis tools such as the Relative Strength Index (RSI), Moving Averages, and Average True Range (ATR) is captured through the Sharpe and the Sharpe per trade. The analysis is divided according to regional, sector, and global EO indices, fossil fuel-based indices, and the key global stock market indices. Our findings reveal that a momentum-based strategy performed best for the MSCI Global Alternative Energy index with the highest excess return per unit of risk, followed by the fossil fuel-based indices. A trend-based strategy worked best for the MSCI Global Alternative Energy and EO 100 indices. The use of volatility-based information yielded the highest Sharpe ratio for EO Europe, followed by the Oil and Gas Exploration and Production industry, and MSCI Global Alternative Energy. We further find that a trader relying on a system which simultaneously provides momentum, trend, or volatility information would yield positive returns only for the MSCI Global Alternative Energy, the S&P Oil and Exploration and Production industry, NYSE Arca Oil, and FTSE 100 indices. Overall, despite the superior performance of the MSCI Global Alternative Energy index when using momentum and trend strategies, most region and sector EOs performed poorly compared to fossil fuel-based indices. The results suggest that the existing crude oil prices continue to allow fossil fuel-based equity investments to outperform most environmentally sustainable equity investments. These findings support that sustainable investments, on average, have yet to demonstrate consistent superior performance over non-renewable energy investments which demonstrates the need for continued, rigorous, and accommodating regulatory policy actions from government bodies in order to reorient significant capital flows towards sustainable equity investments.

What can we learn from the 2008 financial crisis for global power decarbonization after COVID-19?

Since the outbreak of the COVID-19 pandemic, power generation and the associated CO2 emissions in major countries have experienced a decline and rebound. Knowledge on how an economic crisis affects the emission dynamics of the power sector would help alleviate the emission rebound in the post-COVID-19 era. In this study, we investigate the mechanism by which the 2008 global financial crisis sways the dynamics of power decarbonization. The method couples the logarithmic mean Divisia index (LMDI) and environmentally extended input-output analysis. Results show that, from 2009 to 2011, global power generation increased rapidly at a rate higher than that of GDP, and the related CO2 emissions and the emission intensity of global electricity supply also rebounded;the rapid economic growth in fossil power-dominated countries (e.g., China, the United States, and India) was the main reason for the growth of electricity related CO2 emissions;and the fixed capital formation was identified as the major driver of the rebound in global electricity consumption. Lessons from the 2008 financial crisis can provide insights for achieving a low-carbon recovery after the COVID-19 crisis, and specific measures have been proposed, for example, setting electricity consumption standards for infrastructure construction projects to reduce electricity consumption induced by the fixed capital formation, and attaching energy efficiency labels and carbon footprint labels to metal products (e.g., iron and steel, aluminum, and fabricated metal products), large quantities of which are used for fixed capital formation. © 2023 The Authors

Holistic and integrated systemic policies and practices for decarbonization

A bold, visionary, transforming, systemic, holistic, integrated, caring, inclusive, equitable, sustainable, and resilient paradigm for fast transitions toward a clean energy and decarbonized future is imperative and urgently needed. Business as usual and silo approaches are not viable with the changes that are occurring. These changes are linked and interacting systems of physical, natural, health, social, economic, finance, governance, and institution. The effects and impacts are dire, existential, and pervasive. The 2021 IPCC Report Physical Science Basis: Summary for Policymakers, in clear language stated "it is unequivocal that human influence has warmed the atmosphere, oceans and land”. The scientific communities in the US, Europe, Asia and other regions all subscribe to this situation. Well documented global empirical evidence is also confirming the profound systems and systemic transformations that are occurring. Business, industry, and the general public, in particular youths, worldwide are all increasingly demanding actions – that transcend words of what needs to be done to deeds of how and now. In the US, the 2022 Inflation Reduction Act, would allocate US 370 billion for combating climate change and clean energy production. The IRA is the largest climate spending package ever. President Biden has called for 100% clean electricity by 2035 and pledged to cut carbon emissions by 50%–52% below 2005 levels by the end of this decade, doubling the previous target. A decarbonized future was endorsed by Leaders at the 2021 G-7 Carbis, UK Summit. There is growing realization that the global climate change crisis requires strengthened and expanded global cooperation with new, innovative and non-bureaucratic mechanisms for collaboration. The 2021 IPCC Report summarized that global surface temperature will continue to increase until at least the mid- century under all emissions' scenarios considered. "Global warming of 1.5 and 2°C will be exceeded during the 21st century unless deep reductions in CO2 and other greenhouse gas emissions occur in the coming decades.” The UNEP and IEA contends reducing anthropogenic methane emissions will help mitigate climate change and is a cost-effective proposition. The release of methane and micro-organisms from melting of permafrost needs to be better studied and understood., The confluence of increased heat, humidity, fine particulates air pollution, water contaminants and the COVID pandemic, will exacerbate health burdens. This will have serious consequences for human wellbeing, and cascading into national and global security. With climate change, therapeutics and vaccines will not work. The article provides a brief overview of the unprecedented climate related hurricanes, storms, floods and wildfires disasters occurring in all regions of the world. It highlights of some of the key effects, impacts and consequences with current policies and practices with regard to the energy-climate conundrum. There is an imperative to change course toward a decarbonized future. A number of systemic expeditious interventions are delineated. These include actions by all on:. The* fundamental need to change behavior;*afforestation, reforestation, rehabilitation of wetlands, mangroves, wastelands and coral reefs to restore ecosystem functions which would also create significant number of employment and livelihoods' opportunities;*retrofitting existing structures to be more energy efficient, incorporate increasing renewable energy, sustainability and resiliency criteria, – to "build back better” and provide jobs;*the life cycle of food and agriculture practices need to be systemically examined to reduce adverse impacts on climate, Energy, environment and health. There are difficulties and challenges. The commensurate opportunities and benefits of a decarbonized paradigm include clean and safe jobs;healthy quality of life;and a sustained and resilient future for current and future generations. © 2023 American Institute of Chemical Engineers.

An Evaluation of ASEAN Renewable Energy Path to Carbon Neutrality

Maintaining our standard of living and keeping the economy running smoothly is heavily reliant on a consistent supply of energy. Renewable energy systems create abundant energy by utilizing resources such as the sun, wind, earth, and plants. The demand for renewable energy is increasing, despite power scarcity, pollution, and climate change posing challenges to long-term development in the Association of Southeast Asian Nations (ASEAN), which has seen significant social and economic growth in recent years. To achieve its 23% renewable energy (RE) target, ASEAN can develop solar photovoltaic (PV) electricity. Members of the ASEAN have established regulations and incentives to encourage individuals and businesses to use renewable energy in the future. This paper explores Southeast Asian countries' comprehensive fossil-free energy options, the region's renewable energy potential, current capacity, goals, and energy needs. Through the ASEAN Plan of Action for Energy Cooperation (APAEC) 2016–2025 and the ASEAN Declaration on Renewable Energy, ASEAN is committed to reducing its greenhouse gas emissions and promoting sustainable development aligning with the Paris Agreement's aim to limit global warming to well below 2 degrees Celsius above pre-industrial levels. Results show that decarbonizing the region's energy system is possible, but current policies and actions must be altered to reach that target level. Further research is necessary to optimize the ASEAN region's renewable resource technical potential and commercial viability with available technology.

Modelling a smart tech user journey to decarbonise tourist accommodation

Smart tech offers much promise for tourism recovery from the COVID-19 crisis and the broader issue of decarbonising tourism. This paper investigates how accommodation managers engaged with smart tech during the crisis, and the journey of learning how to use numerical data output to drive sustainability actions. Interviews with nine accommodation managers/owners at six sites uncovers a ‘tech journey' that extends prior to, and beyond, the acquisition and installation of the smart technology itself. The journey is explained by a new framework that recognises the need for users (here, the accommodation managers) of smart tech to ‘make it their own', integrating it into their decisions, workflows and finally, identity. This can only happen through a capacity to understand what the data (i.e. numerical outputs) mean, and a process of transforming data into actions. Understanding these processes of ‘data domestication' and ‘data clotting' addresses key gaps in how to achieve potentially radical changes in resource use. Only one case study site had reached this final stage of the journey. The theoretical framework uses the findings from each case to propose early diagnostic questions/tools that can help identify where smart system may need assistance to move from data to action.

Can the Growth of the Digital Economy Be Beneficial for Urban Decarbonization? A Study from Chinese Cities

An environmentally friendly city is a livable home for the future. Can the rapidly developing digital economy help decrease carbon emissions and realize a low-carbon and clean city promptly? This study focuses on examining how multi-dimensional digital economic growth has influenced CO2 emissions across 280 Chinese cities from 2011 to 2019. Findings discover that (1) An "n”-type curve nexus exists between CO2 emissions and the digital economy in Chinese cities, which means that digital economy expansion initially strengthens CO2 emissions, but at a certain level, it can help achieve the target of urban decarbonization;(2) The digital economy's influence on CO2 emissions is spatially spilled and regionally heterogeneous, and by means of economies of scale and industrial composition upgrades, it can help the city to lower carbon emissions and benefit the low carbonization of neighboring cities. However, based on the "rebound effect”, the intermediary role of technological effects in reducing emissions in the short term is not apparent;(3) The expansion of trade openness and appropriately stringent environmental rules in line with national conditions are beneficial to lower CO2 emissions in the city and the surrounding cities in the short term. It is recommended that policy makers actively promote the development of the digital economy, strengthen exchanges and cooperation between cities, narrow the gap between cities, and actively learn the advanced management concepts of surrounding cities through the development of economies of scale and industrial structure transformation to accomplish the target of "carbon neutrality” sooner rather than later.

ROMANIAN COAL BETWEEN DECARBONIZATION PROGRAMS, EXPLOITATION CLOSURE AND ENERGY CRISIS

The energy crisis triggered globally in the last quarter of 2021, forced Romania to go through a winter with liberalized electricity and gas prices, a period unprecedented in terms of consumer prices, accentuated by the result of closing energy targets that coal-fired operations as a result of the imposition of EU conditions for the restructuring of the mining and energy sector. The year before, 2020, the COVID-19 pandemic, with restrictions imposed, produced a decrease in electricity demand, a decline in coal-fired power consumption, greatly reduced the share of gas in the energy mix, using preferential renewable energy sources. Subsequently, Russian gas prices have risen to record highs and, as a result, coal-fired power generation has returned to the European Union in 2021, although coal became more expensive and emission allowance prices doubled. In the context of the armed conflict between Russia and Ukraine, major price increases are expected worldwide, generating new risks of exposing the economy and new challenges in terms of ensuring Romania's independence and energy security. Against this background of these situations, can Romania still respect the European commitments of the Green Pact, meet these challenges and respond to the needs of the communities affected by the projected programs? The present paper aims at a critical assessment of the current situation of the Romanian coal mining and future trends of using a "clean coal” as a variant to respond to the requirements of the environmental concerns. © 2022 International Multidisciplinary Scientific Geoconference.

Indicator-based assessment of sustainable energy performance in the European Union

The COVID-19 and the resulting global energy crises highlighted the importance of decarbonization and the necessity of shifting the economy from fossil fuels towards renewable energy sources. Sustainable energy transition is also a key element of circular economy, social welfare and justice. In this paper we developed an indicator set and we compiled a composite indicator to measure the performance of the EU Member States regarding the sustainable energy transition between 2007 and 2019. Our results show significant differences which do not follow the usual East-West division of the integration. Both convergence and divergence can be revealed.

A critique on the UK's net zero strategy

Before the Covid-19 pandemic UK passed net-zero emission law legislation to become the first major economy in the world to end its contribution to global warming by 2050. Following the UK's legislation to reach net-zero emissions, a long-term strategy for transition to a net-zero target was published in 2021. The strategy is a technology-led and with a top-down approach. The intention is to reach the target over the next three decades. The document targets seven sectors to reduce emissions and include a wide range of policies and innovations for decarbonization. This paper aims to accomplish a much needed review of the strategy in heat and buildings part and cover the key related areas in future buildings standard, heat pumps and use of hydrogen as elaborated in the strategy. For that purpose, this research reviews key themes in the policy, challenges, recent advancement and future possibilities. It provides an insight on the overall development toward sustainability and decarbonization of built environment in the UK by 2050. A foresight model, Future Wheels is also used to visualize the findings from the review and provide a clear picture of the potential impact of the policy. © 2023

Ship carbon dioxide emission estimation in coastal domestic emission control areas using high spatial-temporal resolution data: A China case

It is necessary to accurately calculate ship carbon emissions for shipping suitability. The state-of-the-art approaches could arguably not be able to estimate ship carbon emissions accurately due to the uncertainties of Ship Technical Specification Database (STSD) and the geographical and temporal breakpoints in Automatic Identification System (AIS) data, hence requiring a new methodology to be developed to address such defects and further improve the accuracy of emission estimation. Firstly, a novel STSD iterative repair model is proposed based on the random forest algorithm by the incorporation of13 ship technical parameters. The repair model is scalable and can substantially improve the quality of STSD. Secondly, a new ship AIS trajectory segmentation algorithm based on ST-DBSCAN is developed, which effectively eliminates the impact of geographical and temporal AIS breakpoints on emission estimation. It can accurately identify the ships' berthing and anchoring trajectories and reasonably segment the trajectories. Finally, based on this proposed framework, the ship carbon dioxide emissions within the scope of domestic emission control areas (DECA) along the coast of China are estimated. The experiment results indicate that the proposed STSD repair model is highly credible due to the significant connections between ship technical parameters. In addition, the emission analysis shows that, within the scope of China's DECA, the berthing period of ships is longer owing to the joint effects of coastal operation features and the strict quarantine measures under the COVID-19 pandemic, which highlights the emissions produced by ship auxiliary engines and boilers. The carbon intensity of most coastal provinces in China is relatively high, reflecting the urgent demand for the transformation and updates of the economic development models. Based on the theoretical models and results, this study recommends a five-stage decarbonization scheme for China's DECA to advance its decarbonization process. © 2022 Elsevier Ltd

BORON-HYDROGEN MATERIALS TOWARDS DECARBONISATION

Boron-hydrogen (B-H) materials are used as hydrogen and heat sources, due to their reducing potential. It has been shown again with the COVID-19 pandemic that greenhouse gas activities are anthropogenic in origin. In particular, the conversion of carbon dioxide (CO2) into valuable chemicals has an important place in the fight against the climate crisis. The conversion of anthropogenic CO2 into valuable chemicals has important implications for a habitable world. In many studies in the literature, boron hydrides have been used to produce, hydrogen and convert carbon dioxide into valuable chemicals. Formic acid and methanol obtained by hydrogenation can be seen as the clean energy movement of the future with its value in hydrogen storage. The type of valuable chemicals that will be formed by the hydrogenation of CO2 is directly related to the method to be followed. The type of catalyst used, or how much hydrogen molecule interacts with CO2, determines the valuable chemical that will form. Disturbances in the thermodynamics of the hydrogenation of CO2 have been tried to be eliminated by various types of catalysts and necessary condition optimizations. Many catalysts and methods developed for the hydrogenation of CO2 were examined. This study discusses the use of B-H materials via catalytic conversion of CO2 into valuable chemicals in terms of critical factors such as reaction conditions, selection of catalyst, and solvent. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.

SAFE ENERGY RELATIONS: UNFOLDING THE PRECAUTIONARY PRINCIPLE WITH THE ADVENT OF HYDROGEN TECHNOLOGIES

Proposals on the inclusion of hydrogen as an energy vector into the large-scale energy socio-technical system has gained considerable momentum along with the effects of the climate crisis and the COVID-19 pandemic. This study examines the conflict between various dimensions of decarbonization with hydrogen agenda within the conceptual framework of international environmental law and policies. Firstly, we carry out a general due diligence of the technical, economic, and legal aspects of the hydrogen economy particularly in Europe. Subsequently, via textual analyses of European Union's strategic documents, the incompatibility of the hydrogen risk chain with the hydrogen value chain is revealed. Finally, as one remedy to this incompatibility;the precautionary principle, its relation to science, technology and society studies, and its possible policy applications in the context of hydrogen technologies are discussed. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.

Is there any recovery power for economic growth from green finance? Evidence from OECD member countries

This paper investigates the dynamic interactions between green finance, economic growth, and green energy consumption for the Organization of Economic Cooperation and Development (OECD) members. The econometric analysis is conducted on annual data gathered throughout 2010–2020 using different estimation techniques of the Vector Autoregressive model, causality, and co-integration approaches. The main results confirmed a positive bi-directional relationship between GDP and green energy consumption. In addition, there is a two-way relationship between the volume of green bond issuance and the use of green energy in OECD countries. The recommended practical policy recommendations are establishing a unified green bonds market among OECD member states, prioritizing green projects to support the issued green bonds, improving the financial system, and financing rural electrification and electric vehicle transition by green bonds. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

Is Economic Planning Our Future?

The article is devoted to the topic of economic planning at the state level. The historical excursus shows the origins of the planned economy elements on the example of three countries: Japan, India and France, as well as the evolution of its planned policy in the 20th century. The article provides a rationale for the relevance of planning, including as a tool to overcome market failures. The ESG agenda, in particular the issue of reducing the negative anthropological impact on the environment, is seen as one of the drivers for strengthening the role of planning.

The International Decarbonization Regime as a Tool for Implementing Risk Society Values

"The coronavirus pandemic has actualised the ""Global Risk Society"" concept. The purpose of this article is to examine the emergence of an international decarbonisation regime in terms of the values of the ""global risk society"" as updated by the coronavirus pandemic. Under the conditions of ""new normality"", new values that determine the sociopolitical development of society are taking shape. Relying on the ""Global Risk Society"" theory, the authors derive its emerging values, the emergence of which is associated with the pandemic and its socio-economic effects. Thus, new values include the abandonment of faith in progress and a focus on crisis management (resilience), global solidarity as a key condition for survival, the search for a balance between freedom and security, effective response and regulation, ""open innovation"" as part of the ""global commons"", rethinking of the value of consumption, and finally, the value of the climate agenda as a global green imperative comes to the fore. These values are of importance for a global climate agenda as well, which has become more acute during the pandemic. A key actor here is the European Union, which, through its policy of normative power and environmental ethics, is shaping a new international decarbonisation regime as an instrument for realising these values. And this ""new ethic"" has no national boundaries. Such international regime aims to create a regulatory framework for responding to climate risks that has the potential to profoundly affect global development and lead to a fundamentally new international climate order."
