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.

This Selected Issues paper discusses sea-level rise impacts and adaptation in Vanuatu. Sea-level will continue to increase during this century directly caused by global warming and melting of terrestrial ice. While Vanuatu cannot control global sea-level, it can manage how it affects the country by adapting. Staff analysis estimates the cost of sea-level rise under alternative adaptation strategies: (1) no-adaptation; (2) protection; and (3) planned retreat. Such analysis can help the government to identify trade-offs between efficiency and equity, and choose according to the preferences of the population, consistent with public finance objectives. Preliminary results show that complete protection of coastal areas in Vanuatu is costly while planned retreat from the coastline is the least-cost adaptation response. However, given the mountainous nature of the islands, only small areas of the main population centers of Port Vila and Luganville are at risk of being permanently inundated even with very high sea level rise.

Do weather shocks worsen conflict around the world? To answer this question, this paper uses an innovative dataset created by using georeferencing to match weather and conflict data at the subregional level on a monthly frequency across 168 countries over 2013 to 2022.The empirical results show that higher temperature exacerbate conflict where it already exists. Estimations indicate that, in a high emissions scenario and all else equal, by 2060 conflict deaths as a share of the population for a median country facing conflict could increase by 12.3 percent due to rising temperatures. These findings underscore the importance of integrating climate resilience into peace and security efforts and designing climate adaptation policies that support conflict prevention and resolution.

Curbing carbon emissions to meet the targets set in the Paris Agreement requires the deployment of low carbon technologies (LCTs) at a global scale. This paper assesses the role of climate and trade policies in fostering LCT diffusion through trade. Leveraging a comprehensive database of climate policies and a new database identifying trade in low carbon technologies and the tariffs applied to these goods, this paper shows that the introduction of new climate policies has a positive and significant impact on LCT imports. Zooming into specific climate policies, the paper finds that, except for non-binding ones, all climate policies stimulate LCT imports. The paper also highlights the role of trade policies as an engine of LCT diffusion—reductions in tariffs applied on LCT goods have a sizeable impact on LCT imports. On the flip side, results suggest that more protectionist measures would impede the spread of low-carbon technologies.

This Selected Issues paper focuses on housing affordability in Andorra. This paper shows a granular analysis of housing affordability, exploiting microdata from the Survey of Living Conditions, to identify the groups that are most affected and better inform and target housing policies. Evidence that affordability is lower for renters and that Andorra is a renter-dominated real estate market combines to create a housing affordability issue. Low-income and low-skilled workers are disproportionally affected. This study analyzes the evolution and characteristics of housing demand and supply dynamics in the country, which indicates a supply and demand mismatch in the affordable segment of the Andorran housing market as well as insufficient fluidity, which exacerbates the shortage of short-term rentals and complicates the hiring of foreign workers. A multipronged policy approach is needed, and a careful balance is needed to minimize market distortions while increasing the stock of housing in the medium-term.

The transition to a sustainable future in the Asia-Pacific region has global economic significance. Despite driving global growth in recent years, the region's heavy coal reliance led to significant greenhouse gas emissions. Meeting climate mitigation and adaptation needs in emerging and developing Asia requires investment of at least $1.1 trillion annually. Actual investment falls short by about $800 billion. Asia-Pacific’s environmental performance has also hampered its ability to tap into private flows from the fast-growing ESG asset class, keeping the cost of issuing sustainable debt instruments relatively high compared to other regions. This paper provides an overview of the climate finance ecosystem in countries in the Asia-Pacific region and presents strategies to mobilize climate finance for the region’s transition to a sustainable future. The paper identifies challenges, including gaps in the climate information architecture, policy conflicts, global complexities, and emphasizes the need for coordinated action involving governments, central banks, financial supervisors, the IMF, and other multilateral institutions. In particular, • Governments need to establish a well-defined climate strategy with strong institutional oversight and coordination to strengthen the framework on data, taxonomies, and disclosures. Fossil fuel subsidies should be phased out and carbon pricing schemes expanded to create fiscal space for sustainable investments. Strengthening macroeconomic management is essential to attract private capital. • Financial supervisors and central banks should coordinate across jurisdictions to promote global, interoperable disclosure standards, enhance climate risk analysis and reporting, and incorporate climate-related financial risks into prudential frameworks. Developing climate labels for sustainable investment funds and shifting the focus of ESG scores to better capture sustainability and climate impact would foster trust in the evaluations. The IMF can drive climate action by integrating discussions in surveillance activities and strengthening data and statistics—including through capacity building and peer learning—to develop common standards around climate risk measurement and analysis. The Resilience and Sustainability Trust could contribute to reducing financing gaps through its catalytic and reform supporting functions, while multilateral development banks could scale up grant financing and concessional lending, and where appropriate adopt risk-mitigating mechanisms to expand lending capacity. Cooperation among multilateral institutions is essential to align efforts and resources to achieve a balanced allocation between mitigation and adaptation lending.
