This paper reviews the fiscal implications of climate change, and the potential role of the Fund in addressing them. It stresses that: • The potential fiscal implications are immediate as well as lasting, and liable to affect—in differing forms and degree—all Fund members. • Climate change is a global externality problem, calling for some degree of international fiscal cooperation... • ...and has features—an intertemporal mismatch between the (early) costs of action to address climate change and (later) benefits, pervasive uncertainties and irreversibilities (including risk of catastrophe), and sharp asymmetries in the effects on different countries—that raise difficult technical and ethical issues, and hinder policy coordination. • In addition to itself impacting the public finances, climate change calls for deploying fiscal instruments to mitigate its extent and adapt to its remaining effects.

Brack examines the implications of climate change policy measures for international trade: energy efficiency standards for traded goods; carbon/energy taxes, including international taxation of bunker fuels; and the potential use of trade measures in the climate change protocol.

While trade exacerbates climate change, it is also a central part of the solution because it has the potential to enhance mitigation and adaptation. This timely report explores the different ways in which trade and climate change intersect. Trade contributes to the emissions that cause global warming and is itself also affected by climate change through changing comparative advantages. The report also confronts several myths concerning trade and climate change. The Trade and Climate Change Nexus: The Urgency and Opportunities for Developing Countries focuses on the impacts of, and adjustments to, climate change in developing countries and on how future trade opportunities will be affected by both the changing climate and the policy responses to address it. The report discusses how trade can provide the goods and services that drive mitigation and adaptation. It also addresses how climate change creates immense challenges for developing countries, but also new opportunities to promote trade diversification in the transition to a low-carbon world. Suitable trade and environmental policies can offer effective economic incentives to attain both sustainable growth and poverty reduction.

Climate change presents an unprecedented global challenge, and impacts upon a wide range of human economic activity. The issue of how to address climate change in developing countries has provoked international political controversy and the urgent need for effective international responses has become increasingly apparent. The Role of Climate Change in Global Economic Governance addresses the growing number of legal and economic issues that arise with respect to climate change, combining analysis from economic, financial, and legal perspectives. The book assesses how the World Trade Organization, international investment law, and the international intellectual property rights regime approach the economic issues raised by climate change. The authors analyse how climate change regulation interacts with international economic law, and consider how financial instruments and insurance can mitigate the risks posed by climate change and facilitate adaptation. It breaks new ground in considering the financial sector's response to climate change, looking at how market mechanisms and risk insurance can reduce its economic cost.

This paper discusses the implications of climate change for fiscal, financial, and macroeconomic policies. Most pressing is the use of carbon taxes (or equivalent trading systems) to implement the emissions mitigation pledges submitted by 186 countries for the December 2015 Paris Agreement while providing revenue for lowering other taxes or debt. Carbon pricing in developing countries would effectively mobilize climate finance, and carbon price floor arrangements are a promising way to coordinate policies internationally. Targeted fiscal measures that are tailored to national circumstances and robust across climate scenarios are needed to counter private sector under-investment in climate adaptation. And increased disclosure of carbon footprints, stress testing of asset values, and greater proliferation of hedging instruments, will facilitate low-emission investments and climate risk diversification through financial markets.
