This new web format for Environment at a Glance Indicators provides real-time interactive on-line access to the latest comparable OECD-country data on the environment from the OECD Core Set of Environmental Indicators – a tool to evaluate environmental performance in countries and to track the course towards sustainable development. The web version allows users to play with the data and graphics, download and share them, and consult and download thematic web-books. These indicators provide key messages on major environmental trends in areas such as climate change, biodiversity, water resources, air quality, circular economy and ocean resources. They are accompanied by a short Environment at a Glance report that presents a digest of the key messages stemming from the indicators.

Air quality

Air pollution is the world’s leading environmental health risk and a major cause of environmental degradation. Atmospheric pollutants from energy transformation andenergy consumption, and from industrialprocesses,are the main contributors to regional and local air pollution.Major concerns relate to theireffects on humanhealth and ecosystems.Human exposure is particularly high in urban areas where economic activities are concentrated and where demand for mobility is highest. Degraded air quality can have substantial economic and social consequences, from health costs and a lower quality of life to infrastructure maintenance, reduced agricultural output and forest damage. Some population groups are especially vulnerable to air pollution. The very young and the very old are the most at risk.
