Cette série a pour but de rendre accessible à un large public des études clés sur les questions environnementales liées au changement climatique, la performance environnementale d'un pays, la modélisation économique et environnementale, l'innovation environnementale, les taxes environnementales et l'investissement vert.
Les pays en développement sont affectés de manière disproportionnée par la hausse des pertes liées aux événements climatiques extrêmes. Sur la base d’études de cas en Colombie et au Sénégal, ce document examine comment les pays utilisent la protection financière dans le cadre de leurs approches de gestion des risques climatiques.
On Thursday 6 April, Hannah Leckie & Xavier Leflaive of the OECD Environment Directorate discussed emerging solutions in OECD countries, that can guide the design and implementation of policies to control diffuse water pollution. Water pollution is on the rise due to indirect ‘diffuse’ sources of pollution from both agricultural and urban environments. Watch the video.
The objective of the European Union Water Initiative is to create the conditions for mobilising all available EU resources (human & financial), and to co-ordinate them to achieve the water-related Millennium Development Goals (MDGs) in partner countries. This initiative was launched at the World Summit for Sustainable Development in Johannesburg in 2002.
Green growth is about fostering economic growth and development while ensuring that natural assets continue to provide the resources and environmental services on which our well-being relies. Governments need indicators that can raise awareness, measure progress and identify potential opportunities and risks.
I am delighted to welcome you to this special event, expressing the commitment of the OECD to sustainability. We are here because we need to practice what we preach. We advise governments on how to be greener, so the least we can do is an equivalent effort to green the OECD and its management practices.
The OECD supports countries of Eastern Europe, Caucasus and Central Asia (EECCA) to reconcile their environment and economic goals thus addressing the heavy environmental legacy of the Soviet model of development. This support is provided within the framework of the GReen Economy and ENvironment Action Programme (the GREEN Action Ptogramme).

Earth observation data is a unique source of commensurable information. It can be combined with administrative, social and economic data at multiple scales for in-depth policy analysis. The OECD is currently working with earth observation data providers and key partners to develop its geospatial data capacity.
On 22 March each year the world turns its attention to the global water crisis on the occasion of World Water Day. Water policies around the world are in need of urgent reform. Water - an essential natural resource on which all life depends - has become a global garbage can.
After decades of regulation and investment to reduce point source water pollution, OECD countries still face water quality challenges (e.g. eutrophication) from diffuse agricultural and urban sources of pollution, that is disperse pollution from surface runoff, soil filtration and atmospheric deposition. The relative lack of progress reflects the complexities of controlling multiple pollutants from multiple sources, their high spatial and temporal variability, associated transactions costs, and limited political acceptability of regulatory measures. This report outlines the water quality challenges facing OECD countries today, presents a range of policy instruments and innovative case studies of diffuse pollution control, and concludes with an integrated policy framework to tackle diffuse water pollution. An optimal approach will likely entail a mix of policy interventions reflecting the basic OECD principles of water quality management – pollution prevention, treatment at source, the polluter pays and beneficiary pays principles, equity, and policy coherence.
