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.

Première économie mondiale, les États-Unis ont progressé dans la réduction de plusieurs pressions environnementales tout en conservant l’un des produits intérieurs bruts par habitant les plus élevés au monde. Les émissions de gaz à effet de serre et de polluants atmosphériques, les prélèvements d’eau et la consommation intérieure de matières y ont été découplés de la croissance économique et démographique. Les niveaux de consommation élevés, les pratiques agricoles intensives, le changement climatique et l’étalement urbain continuent toutefois d’exercer des pressions sur le milieu naturel. Malgré l’accélération récente de l’action publique face au changement climatique, des efforts supplémentaires sont nécessaires pour atteindre l’objectif de neutralité en gaz à effet de serre d’ici à 2050. Par ailleurs, les États-Unis figurent parmi les principaux producteurs de déchets marins, lesquels ont de graves conséquences pour les populations et l’environnement. Le présent rapport contient 30 recommandations visant à aider les États-Unis à améliorer leurs performances environnementales, et accorde une attention particulière à l’enjeu des déchets marins et à la problématique transversale de la justice environnementale. Troisième Examen environnemental consacré aux États‑Unis, il propose une évaluation indépendante, fondée sur des données factuelles, des performances environnementales du pays au cours de la dernière décennie. 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 sur le site Internet de l’OCDE.

This report provides a global assessment and outlook on wildfire risk in the context of climate change. It discusses the drivers behind the growing incidence of extreme wildfires and the attribution effect of climate change. It outlines the environmental, social and economic impacts of wildfires by illustrating the losses and costs observed during recent extreme wildfire events. Building on this, the report presents the findings of a cross-country comparative analysis of how countries’ policies and practices have evolved in recent years in light of observed and projected changes in wildfire risk. The analysis draws on in-depth case studies conducted in Australia, Costa Rica, Greece, Portugal and the United States. The report underlines the urgent need for governments to scale up climate change adaptation efforts to limit future wildfire costs.

The paper is the second in a series of two papers mapping young people’s environmental sustainability competence in EU and OECD countries that were prepared as background for the forthcoming OECD Skills Outlook 2023 publication. The papers are the results of a collaboration between the OECD Centre for Skills and the European Commission - Joint Research Centre (Unit B4) on students’ environmental sustainability competence. The first paper is titled ‘Young people’s environmental sustainability competence: Emotional, cognitive, behavioural and attitudinal dimensions in EU and OECD countries.

Natural hazard-induced disasters (NHID), such as floods, droughts, severe storms, and animal pests and diseases have significant, widespread and long-lasting impacts on agricultural sectors around the world. With climate change set to amplify many of these impacts, a 'business-as-usual' approach to disaster risk management in agriculture cannot continue if we are to meet the challenges of agricultural productivity and sustainability growth, and sustainable development. Drawing from seven case studies – Chile, Italy, Japan, Namibia, New Zealand, Turkey and the United States – this joint OECD-FAO report argues for a new approach to building resilience to NHID in agriculture. It explores the policy measures, governance arrangements, on-farm strategies and other initiatives that countries are using to increase agricultural resilience to NHID, highlighting emerging good practices. It offers concrete recommendations on what more needs to be done to shift from coping with the impacts of disasters, to an ex ante approach that focuses on preventing and mitigating the impacts of disasters, helping the sector be better prepared to respond to disasters, and to adapt and transform in order to be better positioned for future disasters.

Blockchain is mainstreaming, but the number of blockchain for development use-cases with proven success beyond the pilot stage remain relatively few. This paper outlines key blockchain concepts and implications in order to help policymakers reach realistic conclusions when considering its use. The paper surveys the broad landscape of blockchain for development to identify where the technology can optimise development impact and minimise harm. It subsequently critically examines four successful applications, including the World Food Programme’s Building Blocks, Oxfam’s UnBlocked Cash project, KfW’s TruBudget and Seso Global. As part of the on-going work co-ordinated by the OECD’s Blockchain Policy Centre, this paper asserts that post-COVID-19, Development Assistance Committee (DAC) donors and their development partners have a unique opportunity to shape blockchain’s implementation.

The Arctic is a vital region that helps preserve the balance of the global climate. The Arctic environment is particularly sensitive to short-lived climate pollutants, including black carbon, due to their strong warming effect. With ambitious policy action to reduce air pollutants, Arctic Council countries would obtain a positive effect on health and the environment throughout their territory, while also helping to slow down climate change by reducing emissions of black carbon. This report calls for ambitious policy action to reduce air pollution in Arctic Council countries, highlighting the environmental, health, and economic benefits from policy action.
