This report provides actionable advice on how to design and implement fiscal policies for both development and climate action. Building on more than two decades of research in development and environmental economics, it argues that well-designed environmental tax reforms are especially valuable in developing countries, where they can reduce emissions, increase domestic revenues, and generate positive welfare effects such as cleaner water, safer roads, and improvements in human health. Moreover, these reforms need not harm competitiveness. New empirical evidence from Indonesia and Mexico suggests that under certain conditions, raising fuel prices can actually increase firm productivity. Finally, the report discusses the role of fiscal policy in strengthening resilience to climate change. It provides evidence that preventive public investments and measures to build fiscal buffers can help safeguard stability and growth in the face of rising climate risks. In this way, environmental tax reforms and climate risk-management strategies can lay the much-needed fiscal foundation for development and climate action.

Efforts to control atmospheric accumulations of greenhouse gases that threaten to heat up the planet are in their infancy. Although the IMF is not an environmental organization, environmental issues matter for its mission when they have major implications for macroeconomic performance and fiscal policy. Climate change clearly passes both these tests.

This report reviews trends and progress on climate change mitigation policies in 34 OECD countries and 10 partner economies (Brazil, China, Colombia, Costa Rica, Indonesia, India, Latvia, Lithuania, the Russian Federation and South Africa), as well as in the European Union.

Climate change is one of the greatest challenges of this century. Mitigation requires a large-scale transition to a low-carbon economy. This paper provides an overview of the rapidly growing literature on the role of macroeconomic and financial policy tools in enabling this transition. The literature provides a menu of policy tools for mitigation. A key conclusion is that fiscal tools are first in line and central, but can and may need to be complemented by financial and monetary policy instruments. Some tools and policies raise unanswered questions about policy tool assignment and mandates, which we describe. The literature is scarce, however, on the most effective policy mix and the role of mitigation tools and goals in the overall policy framework.

This book shows how city and metropolitan regional governments working in tandem with national governments can change the way we think about responding to climate change.

Ending poverty and stabilizing climate change will be two unprecedented global achievements and two major steps toward sustainable development. But the two objectives cannot be considered in isolation: they need to be jointly tackled through an integrated strategy. This report brings together those two objectives and explores how they can more easily be achieved if considered together. It examines the potential impact of climate change and climate policies on poverty reduction. It also provides guidance on how to create a “win-win†? situation so that climate change policies contribute to poverty reduction and poverty-reduction policies contribute to climate change mitigation and resilience building. The key finding of the report is that climate change represents a significant obstacle to the sustained eradication of poverty, but future impacts on poverty are determined by policy choices: rapid, inclusive, and climate-informed development can prevent most short-term impacts whereas immediate pro-poor, emissions-reduction policies can drastically limit long-term ones.

We propose a macroeconomic model to assess optimal public policy decisions in the the face of competing funding demands for climate change action versus traditional welfare-enhancing capital investment. How to properly delineate the costs and benefits of traditional versus adaption-focused development remains an open question. The paper places particular emphasis on the changing level of risk and vulnerabilities faced by developing countries as they allocate investment toward growth strategies, adapting to climate change and emissions mitigation.
