Sub-Saharan Africa needs to significantly accelerate its electricity generation. While hydropower is prominent in some countries, solar and wind power generation has lagged other world regions, even though sub-Saharan Africa has some of the most favorable conditions. A mix of domestic and external financing can increase both renewable electricity generation and GDP. In a scenario where about $25 bn in climate finance flows are allocated annually to renewable energy, renewable electricity production could be up to 24 percent higher than in a scenario excluding this financing, and annual GDP growth would be boosted by 0.8 percentage point on average over the next decade, accompanied by stronger labor demand in the electricity sector. Policies can help catalyze climate finance. An ambitious package of governance, business regulations, and external sector reforms is associated with a 20 percent increase in climate finance flows and a 7 percent increase in electricity generation over five years. In addition, implementing climate policies is linked to increases in green foreign direct investment announcements and green electricity production.
Cabo Verde faces development challenges from multiple structural factors, including insularity, territorial discontinuity, fragility of ecosystems, and scarcity of natural resources, namely water and arable land. Climate change implications are amplifying these challenges. As an island extension of the arid Sahel zone, Cabo Verde faces severe water shortage, which the country addresses more and more through energy intensive desalination, using electricity produced largely by thermal power plants, which depend entirely on imported fossil fuels. The resulting high energy prices directly impact the cost of water production. In conjunction with climate change induced aridity, the energy-water-climate nexus presents the core development challenge for the country.

We quantify cross-border effects of the recent climate mitigation policies introduced in Canada and the U.S., using the global general equilibrium model IMF-ENV. Notably, with the substantial emission reductions from Canada’s carbon tax-led mitigation policies and the U.S.’ Inflation Reduction Act, these two countries would bridge two-thirds of the gap toward their Nationally Determined Contribution (NDC) goals. While the broadly divergent policies are believed to elicit competitiveness concerns, we find the aggregate cross-border effects within North America to be very limited and restricted to the energy intensive and trade exposed industries. Potential carbon leakages are also found to be negligible. A more meaningful difference triggered by policy heterogeneity is rather domestic, especially with U.S. subsidies increasing energy output while the Canada model with a carbon tax would marginally decrease it. This analysis is complemented by a stylized model illustrating how such divergence can affect the terms of trade, but also how these effects can be countered by exchange rate flexibility, border adjustments or domestic taxation.

This paper presents Paraguay’s Second Review under the Policy Coordination Instrument, Request for an Extension of the Policy Coordination Instrument, Modification of Targets, Inflation Band Consultation, and Request of Arrangement under the Resilience and Sustainability Facility (RSF). The government is committed to continued prudent macroeconomic policies and the implementation of structural reforms, including a series of adaptation and mitigation measures and to preserve and expand its green energy matrix. Barring global and weather-related external shocks, Paraguay’s growth prospects are bright. It remains important for Paraguay to rebuild fiscal buffers, including through implementation of long-standing structural reforms. The re-establishment of the fiscal deficit rule by 2026 is rightfully the government’s key priority. The authorities are committed to implementing an ambitious set of climate-related reforms consistent with maximum access under the RSF. The commitment to implement an ambitious matrix of climate-related reforms, closely coordinated with development partners, will help enhance the country’s image as a ‘green’ investment destination.

Using self-reported data on emissions for a global sample of 4,000 large, listed firms, we document large heterogeneity in environmental performance within the same industry and country. Laggards—firms with high emissions relative to the scale of their operations—are larger, operate older physical capital stocks, are less knowledge intensive and productive, and adopt worse management practices. To rationalize these findings, we build a novel general equilibrium heterogeneous-firm model in which firms choose capital vintages and R&D expenditure and hence emissions. The model matches the full empirical distribution of firm-level heterogeneity among other moments. Our counter-factual analysis shows that this heterogeneity matters for assessing the macroeconomic costs of mitigation policies, the channels through which policies act, and their distributional effects. We also quantify the gains from technology transfers to EMDEs.
Understanding the impact of climate mitigation policies is key to designing effective carbon pricing tools. We use institutional features of the EU Emissions Trading System (ETS) and high-frequency data on more than 2,000 publicly listed European firms over 2011-21 to study the impact of carbon policies on stock returns. After extracting the surprise component of regulatory actions, we show that events resulting in higher carbon prices lead to negative abnormal returns which increase with a firm's carbon intensity. This negative relationship is even stronger for firms in sectors which do not participate in the EU ETS suggesting that investors price in transition risk stemming from the shift towards a low-carbon economy. We conclude that policies which increase carbon prices are effective in raising the cost of capital for emission-intensive firms.

Limiting global warming to 1.5 to 2°C above preindustrial levels requires rapid cuts in greenhouse gas emissions. This includes methane, which has an outsized impact on temperatures. To date, 125 countries have pledged to cut global methane emissions by 30 percent by 2030. This Note provides background on methane emission sources, presents practical fiscal policy options to cut emissions, and assesses impacts. Putting a price on methane, ideally through a fee, would reduce emissions efficiently, and can be administratively straightforward for extractives industries and, in some cases, agriculture. Policies could also include revenue-neutral ‘feebates’ that use fees on dirtier polluters to subsidize cleaner producers. A $70 methane fee among large economies would align 2030 emissions with 2oC. Most cuts would be in extractives and abatement costs would be equivalent to just 0.1 percent of GDP. Costs are larger in certain developing countries, implying climate finance could be a key element of a global agreement on a minimum methane price.

Lockdowns resulting from the COVID-19 pandemic have reduced overall energy demand but electricity generation from renewable sources has been resilient. While this partly reflects the trend increase in renewables, the empirical analysis presented in this paper highlights that recessions result in a permanent, albeit small, increase in energy efficiency and in the share of renewables in total electricity. These effects are stronger in the case of advanced economies and when complemented with environment and energy policies—both market-based measures such as taxes on pollutants, trading schemes and feed-in-tariffs, as well as non-market measures such as emission and fuel standards and R&D investment and subsidies—to incentivize and hasten the transition towards renewable sources of energy.
This paper studies the effect of climate change mitigating policies on innovation in clean energy technologies. Results suggest that the tightening of environmental policies since the early 1990s have made a statistically and economically significant contribution to the increase in clean innovation. These effects generally materialized quickly, within 2 to 3 years of the policy change, and were driven by individually significant marginal effects of both market-based policies – such as feed-in tariffs and trading schemes – as well as non-market policies, such as R&D subsidies or emission limits. Looking at electricity innovation in particular, the paper finds that the estimated effect on total innovation is positive on net, meaning that increased innovation in clean and grey technologies is not offset by a decrease in innovation in dirty technologies. From a policy point of view, the paper’s results call for strong policy efforts to decisively shift innovation towards clean technologies.

Recent research in financial economics has shown that rare large disasters have the potential to disrupt financial sectors via the destruction of capital stocks and jumps in risk premia. These disruptions often entail negative feedback e?ects on the macroecon-omy. Research on disaster risks has also actively been pursued in the macroeconomic models of climate change. Our paper uses insights from the former work to study disaster risks in the macroeconomics of climate change and to spell out policy needs. Empirically the link between carbon dioxide emission and the frequency of climate re-lated disaster is investigated using cross-sectional and panel data. The modeling part then uses a multi-phase dynamic macro model to explore this causal nexus and the e?ects of rare large disasters resulting in capital losses and rising risk premia. Our proposed multi-phase dynamic model, incorporating climate-related disaster shocks and their aftermath as one phase, is suitable for studying mitigation and adaptation policies.
