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.
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.

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.
La population néo-zélandaise jouit d’une haute qualité de vie environnementale et peut accéder à des espaces naturels intacts. Le modèle de croissance du pays, largement fondé sur l’exploitation de ressources naturelles, commence toutefois à montrer ses limites écologiques du fait de l’aggravation des émissions de gaz à effet de serre et de la pollution de l’eau, comme le note l’OCDE dans un nouveau rapport.

New Zealand’s natural environment is part of its cultural identity and a pillar of its economic growth, but it can’t be taken for granted. It is vital to make full use of existing tools to curb environmental pressures.

Korea's rapid economic growth has been accompanied by significant pollution and consumption of resources. Increased investment has improved access to environmental services, but disparities remain between rural and urban areas. The country has created a strong green growth policy framework. Its future prosperity rests on implementing this ambitious transition to a green, low-carbon economy.
The SACAME project supports the socio-economic analysis of chemicals by allowing a better quantification and monetisation of health- and environmental impacts. This research, funded by the European commission, builds on the OECD's work on quantifying the social costs of environmental externalities, particulary in recent years on the costs of air pollution.
