Embedded in Nature: Nature-Related Economic and Financial Risks and Policy Considerations
Charlotte Gardes-Landolfini, William Oman, Jamie Fraser, Mariza Montes de Oca Leon, and Bella Yao
The economy is embedded in, and dependent on, nature. Yet economic activity is degrading nature at an unprecedented pace. Interacting with climate change, nature loss and transformation generates significant threats to the global economy and financial system. However, work on the implications of nature-related risks for macroeconomic and financial sector policies remains at an early stage. This note seeks to contribute to this emerging policy space in three main ways: (i) it proposes a conceptual framework for understanding nature-related risks by mapping out macroeconomic transmission channels, emphasizing their impact on the economy and financial systems through “double materiality;” (ii) it conducts empirical analysis, finding that nearly 38 percent of bank loans of the 100 largest global banks are to harmful subsidies-dependent sectors and 44 percent are exposed to conservation areas under the Global Biodiversity Framework, and that industries most exposed to nature degradation are not well prepared to manage these risks; and (iii) it discusses takeaways for macroeconomic and financial sector policies and frameworks.

Climate Change Challenges and Opportunities in Latin America and the Caribbean

Abstract

The analysis in the book suggests that LAC countries are facing substantial challenges related to climate change but have tools at their disposal to seize the opportunities that the climate change presents. To maximize opportunities and minimize the risks LAC countries will need to improve flexibility and adaptability of their economies. Policies aimed at supporting the reallocation of labor and capital across sectors, investing in basic skills and human capital, improving transparency and economic governance to encourage investment in technology and know-how, and creating fiscal space to manage the climate transition would help LAC countries position themselves to take advantage of the opportunities afforded by the climate transition.

Public Debt Dynamics During the Climate Transition
Daniel Garcia-Macia, Waikei R Lam, and Anh D. M. Nguyen
Managing the climate transition presents policymakers with a tradeoff between achieving climate goals, fiscal sustainability, and political feasibility, which calls for a fiscal balancing act with the right mix of policies. This paper develops a tractable dynamic general equilibrium model to quantify the fiscal impacts of various climate policy packages aimed at reaching net zero emissions by mid-century. Our simulations show that relying primarily on spending measures to deliver on climate ambitions will be costly, possibly raising debt by 45-50 percent of GDP by 2050. However, a balanced mix of carbon-pricing and spending-based policies can deliver on net zero with a much smaller fiscal cost, limiting the increase in public debt to 10-15 percent of GDP by 2050. Carbon pricing is central not only as an effective tool for emissions reduction but also as a revenue source. Delaying carbon pricing action could increase costs, especially if less effective measures are scaled up to meet climate targets. Technology spillovers can reduce the costs but bottlenecks in green investment could unwind the gains and slow the transition.

Mitigating Climate Change at the Firm Level: Mind the Laggards
Damien Capelle, Divya Kirti, Nicola Pierri, and German Villegas Bauer
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.

Impact of COVID-19 on Attitudes to Climate Change and Support for Climate Policies
Mr. Adil Mohommad and Evgenia Pugacheva
This paper inquires into how individual attitudes to climate issues and support for climate policies have evolved in the context of the pandemic. Using data from a unique survey of 14,500 individuals across 16 major economies, this study shows that the experience of the COVID-19 pandemic increased concern for climate change and public support for green recovery policies. This suggests that the global health crisis has opened up more space for policy makers in key large economies to implement bolder climate policies. The study also finds that support for climate policies decreases when a person has experienced income and/or job loss during the pandemic. Protecting incomes and livelihoods in the near-term is thus important also from a climate policy perspective.

The Long-Run Decoupling of Emissions and Output: Evidence from the Largest Emitters
Gail Cohen, João Tovar Jalles, Mr. Prakash Loungani, and Ricardo Marto
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.
