Carbon pricing very effectively encourages the shift of production and consumption choices towards low and zero carbon options that is required to limit climate change. Are countries using this tool to its full potential? This report measures the pricing of CO2-emissions from energy use in 44 OECD and G20 countries, covering around 80% of world emissions.

Addressing the poverty and distributional impacts of carbon pricing reforms is critical for the success of ambitious actions in the fight against climate change. This paper uses a simple framework to systematically review the channels through which carbon pricing can potentially affect poverty and inequality. It finds that the channels differ in important ways along several dimensions. The paper also identifies several key gaps in the current literature and discusses some considerations on how policy designs could take into account the attributes of the channels in mitigating the impacts of carbon pricing reforms on households.

The most important climate agreement in history, the Paris Agreement on Climate Change represents the commitment of the nations of the world to address and curb climate change. Signed in December 2015, it entered into force on 4th November 2016. Countries are moving into implementation, and efforts at all levels will be needed to fulfill its ambitious goals. The Paris Climate Agreement: Commentary and Analysis combines a comprehensive legal appraisal and critique of the new Agreement with a practical and structured commentary to and social drivers behind it, providing an overview of the pre-existing regime, and tracking the history of the negotiations. It examines the evolution of key concepts such as common but differentiated responsibilities, and analyses the legal form of the Agreement and the nature of its provisions. Part II comprises individual chapters on each Article of the Agreement, with detailed commentary of the provisions which highlights central aspects from the negotiating history and the legal nature of the obligations. It describes the institutional arrangements and considerations for national implementation, providing practical advice and prospects for future development. Part III reflects on the Paris Agreement as a whole: its strengths and weaknesses, its potential for further development, and its relationship with other areas of public international law and governance. The book is an invaluable resource for academics and practitioners, policy makers, and actors in the private sector and civil society, as they negotiate the implementation of the Agreement in domestic law and policy.

Why the traditional “pledge and review” climate agreements have failed, and how carbon pricing, based on trust and reciprocity, could succeed. After twenty-five years of failure, climate negotiations continue to use a “pledge and review” approach: countries pledge (almost anything), subject to (unenforced) review. This approach ignores everything we know about human cooperation. In this book, leading economists describe an alternate model for climate agreements, drawing on the work of the late Nobel laureate Elinor Ostrom and others. They show that a “common commitment” scheme is more effective than an “individual commitment” scheme; the latter depends on altruism while the former involves reciprocity (“we will if you will”). The contributors propose that global carbon pricing is the best candidate for a reciprocal common commitment in climate negotiations. Each country would commit to placing charges on carbon emissions sufficient to match an agreed global price formula. The contributors show that carbon pricing would facilitate negotiations and enforcement, improve efficiency and flexibility, and make other climate policies more effective. Additionally, they analyze the failings of the 2015 Paris climate conference. Contributors Richard N.

This open access book evaluates, from an economic perspective, various measures introduced in Japan to prevent climate change. Although various countries have implemented such policies in response to the pressing issue of climate change, the effectiveness of those programs has not been sufficiently compared. In particular, policy evaluations in the Asian region are far behind those in North America and Europe due to data limitations and political reasons. The first part of the book summarizes measures in different sectors in Japan to prevent climate change, such as emissions trading and carbon tax, and assesses their impact. The second part shows how those policies have changed the behavior of firms and households. In addition, it presents macro-economic simulations that consider the potential of renewable energy. Lastly, based on these comprehensive assessments, it compares the effectiveness of measures to prevent climate change in Japan and Western countries. Providing valuable insights, this book will appeal to both academic researchers and policymakers seeking cost-effective measures against climate change.

This paper discusses the role of, and provides practical country-level guidance on, fiscal policies for implementing climate strategies using a unique and transparent tool laying out trade-offs among policy options.

For decades, the world’s governments have struggled to move from talk to action on climate. Many now hope that growing public concern will lead to greater policy ambition, but the most widely promoted strategy to address the climate crisis – the use of market-based programs – hasn’t been working and isn’t ready to scale. Danny Cullenward and David Victor show how the politics of creating and maintaining market-based policies render them ineffective nearly everywhere they have been applied. Reforms can help around the margins, but markets’ problems are structural and won’t disappear with increasing demand for climate solutions. Facing that reality requires relying more heavily on smart regulation and industrial policy – government-led strategies – to catalyze the transformation that markets promise, but rarely deliver.
