The scientific consensus is clear: climate change is associated with increasingly frequent and intense natural disasters ranging from droughts and wildfires to hurricanes and coastal flooding. While the extent of the economic damage cannot be known for certain, strong evidence suggests it could be quite severe. The challenge for policymakers will be to decide how much to spend on measures to reduce greenhouse gas emissions. To do that, they must be able to compare the costs of various options, including renewable-energy sources and electric cars.

This paper discusses sectoral policies needed to achieve the ambitious greenhouse gas (GHG) emissions reduction targets announced in the European Union’s Green Deal, complementing the companion paper “EU Climate Mitigation Policy”, which focuses on broader EU-level policies.
With total emissions nearly a quarter below their 1990 level, the EU has made important progress, but the new goals will require much stronger policy action. Moreover, progress has varied across sectors. Emissions from power and industry have fallen by about a third, buildings by a quarter and agriculture by a fifth – while transport emissions have risen. This paper argues that this divergence reflects differences in effective carbon prices, but also cost differences among the available abatement channels, market imperfections, and policy gaps. It discusses specific sectoral policies needed to address these factors and achieve the new emissions reduction goals.
For the latest thinking about the international financial system, monetary policy, economic development, poverty reduction, and other critical issues, subscribe to Finance & Development (F&D). This lively quarterly magazine brings you in-depth analyses of these and other subjects by the IMF’s own staff as well as by prominent international experts. Articles are written for lay readers who want to enrich their understanding of the workings of the global economy and the policies and activities of the IMF.
Five years after the first stirrings of the crisis, some countries have recovered, but others are still struggling. F&D looks at the world today and sees a complex and mixed picture for the future of the world economy. In "Tracking the Global Recovery" we learn that most emerging markets seem to have moved on from the effects of the crisis, but most advanced economies have not. "Fixing the System" looks at how the pace of reforms to strengthen financial regulation has now slowed. World Bank trade economist Bernard Hoekman takes stock of incipient moves toward protectionism in "Trade Policy: So Far So Good?". "Bystanders at the Collapse" looks at how emerging markets and low-income countries weathered the global recession. Financier Mohamed El-Erian weighs in on the potential threat posed by large payment surpluses and deficits in "Stable Disequilibrium." Also in the magazine, we explore what's happening in commodities markets, assess the rise of green technologies, take a look at the shifts in South Asia's labor force, and uncover the harm money laundering can inflict on national economies. F&D's People in Economics series profiles Laura Tyson, Minder of the Gaps, and the Back to Basics series explains how money markets provide a way for borrowers to meet short-term financial needs.

This paper fills a gap in the macroeconomic literature on renewable sources of energy. It offers a definition of green investment and analyzes the trends and determinants of this investment over the last decade for 35 advanced and emerging countries. We use a new multi-country historical dataset and find that green investment has become a key driver of the energy sector and that its rapid growth is now mostly driven by China. Our econometric results suggest that green investment is boosted by economic growth, a sound financial system conducive to low interest rates, and high fuel prices. We also find that some policy interventions, such as the introduction of carbon pricing schemes, or "feed-in-tariffs," which require use of "green" energy, have a positive and significant impact on green investment. Other interventions, such as biofuel support, do not appear to be associated with higher green investment.
