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.

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 paper explores how fiscal policy can affect medium- to long-term growth. It identifies the main channels through which fiscal policy can influence growth and distills practical lessons for policymakers. The particular mix of policy measures, however, will depend on country-specific conditions, capacities, and preferences. The paper draws on the Fund’s extensive technical assistance on fiscal reforms as well as several analytical studies, including a novel approach for country studies, a statistical analysis of growth accelerations following fiscal reforms, and simulations of an endogenous growth model.

This report emphasizes the environmental, fiscal, economic, and administrative case for using carbon taxes, or similar pricing schemes such as emission trading systems, to implement climate mitigation strategies. It provides a quantitative framework for understanding their effects and trade-offs with other instruments and applies it to the largest advanced and emerging economies. Alternative approaches, like “feebates” to impose fees on high polluters and give rebates to cleaner energy users, can play an important role when higher energy prices are difficult politically. At the international level, the report calls for a carbon price floor arrangement among large emitters, designed flexibly to accommodate equity considerations and constraints on national policies. The report estimates the consequences of carbon pricing and redistribution of its revenues for inequality across households. Strategies for enhancing the political acceptability of carbon pricing are discussed, along with supporting measures to promote clean technology investments.

Public financial management (PFM) consists of all the government’s institutional arrangements in place to facilitate the implementation of fiscal policies. In response to the growing urgency to fight climate change, “green PFM” aims at adapting existing PFM practices to support climate-sensitive policies. With the cross-cutting nature of climate change and wider environmental concerns, green PFM can be a key enabler of an integrated government strategy to combat climate change. This note outlines a framework for green PFM, emphasizing the need for an approach combining various entry points within, across, and beyond the budget cycle. This includes components such as fiscal transparency and external oversight, and coordination with state-owned enterprises and subnational governments. The note also identifies principles for effective implementation of a green PFM strategy, among which the need for a strong stewardship located within the ministry of finance is paramount.
