UNEP: Actions on air quality
A new report by the United Nations Environment Programme (UNEP) lists ten basic measures to improve air quality. It shows that the majority of countries worldwide are still to adopt these air quality policy actions, but highlights many good examples that can be followed to spark worldwide action. It points out that while policies and standards on clean fuels and vehicles could reduce emissions by 90 per cent, only 29 per cent of countries worldwide have adopted Euro 4 emission standards or above.
