As climate change increases exposure to natural disasters, countries need new solutions to mitigate risks of natural hazards. For many in Asia and the Pacific, mobilising existing resources is not enough: they need to consider a grand design of disaster risk financing strategies. Catastrophe bonds (CAT bonds) can be an effective, market-based financing tool for the region. While the global CAT bond market has grown steadily since the 1990s, it remains weakly developed in Asia and the Pacific. Its successful development there requires robust purpose-built legal frameworks; developed general bond markets, especially in local currency; appropriate capacity building; and data-driven pricing models. This report explores each of these conditions along with policy suggestions for fostering them, and discusses the development of multi-country CAT bonds in Asia and the Pacific.

This report presents developments of the work of the Inclusive Forum on Carbon Mitigation Approaches (IFCMA) to the G20 Finance Ministers and Central Bank Governors, and reflect on the IFCMA’s achievements one year on from its launch in February 2023.

Many ocean economic activities are not readily visible in official statistics, hindering policymakers' access to crucial information for decision making. The OECD ocean economy measurement project aims to address this by aligning ocean economy statistics with broader economic data and ensuring international consistency. This paper compares the measurement strategies of eight OECD member countries using principles from the system of national accounts. It also highlights the ocean economy thematic accounts of four countries and summarises their methods. The paper concludes with recommendations for integrating ocean economy measurements with national accounting standards, a vital step for improving the evidence base for ocean policymaking.

As countries scale up climate action, they face the challenge of expanding renewable power while tackling biodiversity loss. Transitioning away from fossil fuels can reduce climate-related pressure on biodiversity, but brings its own risks. Unless carefully managed, the expansion of renewable power could compromise biodiversity. This report synthesises evidence on biodiversity impacts from renewable power infrastructure, with a focus on solar power, wind power and power lines. It identifies opportunities for mainstreaming biodiversity into power sector planning and policy to deliver better outcomes for nature and the climate. Drawing on good practice insights from across the globe, the report offers governments recommendations to align renewable power expansion with biodiversity goals.

Reaching climate neutrality requires economic transformations of unprecedented scale and speed. Immediate action from the business community can avoid unnecessary costs, create wellbeing co-benefits and prepare local businesses with a better competitive position in the future climate neutral economy. This report shows what reaching climate neutrality by 2040 means for Hamburg businesses and identifies key actions they need to undertake. It provides insights where the Hamburg economy and its businesses stand on the way to climate neutrality and on their needs to advance, drawing on a business survey. The study also shares insights from action plans of selected comparison cities. It points to cross-sector as well as to sector-specific challenges and opportunities for Hamburg businesses. This includes making better use of low-cost renewables, addressing energy efficiency in buildings as well as challenges and opportunities in activities in and around the port and in industry. It highlights Hamburg's potential as a hydrogen hub as well as the need to adopt circular economy practices. It illustrates that a regional and business perspective are necessary to achieve climate neutrality in prosperity, requiring individual and collective business action.

The frequency and severity of extreme wildfires are on the rise in the United States, causing unprecedented disruption and increasingly challenging the country’s capacity to contain losses and damages. These challenges are set to keep growing in the context of climate change, highlighting the need to scale up wildfire prevention and climate change adaptation. This paper provides an overview of the United States’ wildfire policies and practices and assesses the extent to which wildfire management in the country is evolving to adapt to growing wildfire risk under climate change.

The paper analyses the current system of environmental taxation and environmental expenditure in Ukraine, identifies issues in the way environmental tax policy is currently designed and implemented and highlights main areas where environmental taxation and expenditure could be improved. It uses data on environmental tax revenue and budgets from expenditure reports of the State Treasury Service of Ukraine over the period 2010 - 2020. Where available, preliminary data for 2021 were also included. The paper aims to support the government of Ukraine in reforming environmental taxation and public funding for environmental protection. Ukraine’s Post-War Recovery and Reconstruction Plan outlines ambitious plans for reform, including in the environmental domain. It envisions restructuring the current environmental tax system, expanding it to energy and transport and harmonising it with that of the European Union. It also foresees an analytical study systematising current taxes and payments in line with Eurostat classification standards. This paper can support these efforts.

L'Allemagne a continué à améliorer ses performances environnementales au cours de la dernière décennie. Elle s'est fixée des objectifs climatiques ambitieux visant à atteindre la neutralité climatique d'ici 2045 et à parvenir à des émissions négatives après 2050. Toutefois, l'Allemagne devra accélérer encore son action climatique, en particulier dans les secteurs du bâtiment et des transports. La triple crise de l'énergie, du climat et de la biodiversité appelle des solutions intégrées et systémiques. En réponse à la crise énergétique, l’Allemagne a pris une série de mesures d’une ampleur historique. Celles-ci devraient accélérer massivement sa transition vers l'énergie verte au cours des années à venir. L’Allemagne renforce également son engagement en faveur de l’adaptation au changement climatique à tous les niveaux de gouvernement, et a lancé un programme ambitieux visant à encourager les investissements dans des solutions fondées sur la nature. Il s’agit du quatrième Examen environnemental de l’Allemagne. Il propose 28 recommandations pour aider l’Allemagne à améliorer ses performances environnementales. La présente version abrégée contient le résumé, de même que l’évaluation et les recommandations officielles du rapport. Le rapport complet est disponible en anglais et en allemand sur le site Internet de l’OCDE.
