We provide a comprehensive analysis of the relationship between greenhouse gas (GHG) emissions and GDP in China using both aggregate and provincial data. The Kuznets elasticity is about 0.6 for China, higher than that in advanced countries but below that of major emerging markets. The elasticity is somewhat lower for consumption-based emissions than for production-based emissions, providing mild evidence consistent with the “pollution haven” hypothesis. The Kuznets elasticity is much lower for the last three decades than for the three previous decades, suggesting a longer-term trend toward decoupling as China has become richer. Further evidence of this comes from provincial data: richer provinces tend to have smaller Kuznets elasticities than poorer ones. In addition to the trend relationship, we find that the Environmental Okun's Law holds in China.

For the world's 20 largest emitters, we use a simple trend/cycle decomposition to provide evidence of decoupling between greenhouse gas emissions and output in richer nations, particularly in European countries, but not yet in emerging markets. If consumption-based emissions—measures that account for countries' net emissions embodied in cross-border trade—are used, the evidence for decoupling in the richer economies gets weaker. Countries with underlying policy frameworks more supportive of renewable energy and climate change mitigation efforts tend to show greater decoupling between trend emissions and trend GDP, and for both production- and consumption-based emissions. The relationship between trend emissions and trend GDP has also become much weaker in the last two decades than in preceding decades.

Natural disasters and climate change are interrelated macro-critical issues affecting all
Pacific small states to varying degrees. In addition to their devastating human costs, these
events damage growth prospects and worsen countries’ fiscal positions. This is the first
cross-country IMF study assessing the impact of natural disasters on growth in the Pacific
islands as a group. A panel VAR analysis suggests that, for damage and losses equivalent to
1 percent of GDP, growth drops by 0.7 percentage point in the year of the disaster. We also
find that, during 1980-2014, trend growth was 0.7 percentage point lower than it would have
been without natural disasters. The paper also discusses a multi-pillar framework to enhance
resilience to natural disasters at the national, regional, and multilateral levels and the
importance of enhancing countries’ risk-management capacities. It highlights how this
approach can provide a more strategic and less ad hoc framework for strengthening both ex
ante and ex post resilience and what role the IMF can play.
While the world’s attention is on dealing with the COVID-19 pandemic, climate change remains a greater existential threat to vulnerable countries that are highly dependent on a weather-sensitive sector like tourism. Using a novel multidimensional index, this study investigates the long-term impact of climate change vulnerability on international tourism in a panel of 15 Caribbean countries over the period 1995–2017. Empirical results show that climate vulnerability already has a statistically and economically significant negative effect on international tourism revenues across the region. As extreme weather events are becoming more frequent and severe over time, our findings indicate that the Caribbean countries need to pursue comprehensive adaptation policies to reduce vulnerabilities to climate change.
The shutdown in economic activity due to the coronavirus disease (COVID-19) crisis has resulted in a short-term decline in global carbon emissions, but the long-term impact of the pandemic on the transition to a low-carbon economy is uncertain. Looking at previous episodes of financial and economic stress to draw implications for the current crisis, we find that tighter financial constraints and adverse economic conditions are generally detrimental to firms’ environmental performance, reducing green investments. The COVID-19 crisis could thus potentially slow down the transition to a low-carbon economy. In light of the urgent need to reduce global greenhouse gas emissions, these findings underline the importance of climate policies and green recovery packages to boost green investment and support the energy transition. Policies that support the sustainable finance sector, such as improved transparency and standardization, could further help mobilize green investments.
