This paper estimates multipliers for spending in clean energy and biodiversity conservation to help inform stimulus measures for a post-COVID-19 sustainable recovery. Using a new international dataset, part of which was especially assembled for this analysis, we find that every dollar spent on key carbon-neutral or carbon-sink activities—from zero-emission power plants to the protection of wildlife and ecosystems—can generate more than a dollar’s worth of economic activity. The estimated multipliers associated with green spending are about 2 to 7 times larger than those associated with non-eco-friendly expenditure, depending on sectors, technologies and horizons. These findings survive several robustness checks and suggest that ‘building back better’ could be a win-win for economies and the planet.
The global economy is climbing out from the depths to which it had plummeted during the Great Lockdown in April. But with the COVID-19 pandemic continuing to spread, many countries have slowed reopening and some are reinstating partial lockdowns to protect susceptible populations. While recovery in China has been faster than expected, the global economy’s long ascent back to pre-pandemic levels of activity remains prone to setbacks.

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.
This paper studies the economic costs of hurricanes in the Caribbean by constructing a
novel dataset that combines a detailed record of tropical cyclones’ characteristics with
reported damages. I estimate the relation between hurricane wind speeds and damages in
the Caribbean; finding that the elasticity of damages to GDP ratio with respect to
maximum wind speeds is three in the case of landfalls. The data show that hurricane
damages are considerably underreported, particularly in the 1950s and 1960s, with
average damages potentially being three times as large as the reported average of 1.6
percent of GDP per year. I document and show that hurricanes that do not make landfall
also have considerable negative impacts on the Caribbean economies. Finally, I estimate
that the average annual hurricane damages in the Caribbean will increase between 22 and
77 percent by the year 2100, in a global warming scenario of high CO2 concentrations and
high global temperatures.

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.
This paper discusses structure, impact, costs, and efficiency of renewable energy supply in the eight largest advanced economies (the G-7 plus Spain), with focus on Germany. Renewables production costs are compared to benefits, defined as reductions in net carbon emissions; technological innovation, and increased energy security. The latter part of the paper centers on Germany, the main European producer of non-traditional renewables. We question whether the level of subsidies can be justified, relative to other means to increase energy security and reduce carbon emissions. We also find an excessive emphasis on current productive activity, relative to development of new technologies.
