A majority of people living in Asian cities are exposed to unhealthy levels of air pollution every day. Seven out of 10 cities in developing Asian countries have unhealthy levels of air pollution, when measured as annual levels of particulate matter with size range of not greater than 10 microns (PM10).

This study establishes a baseline inventory of the number, types, and approximate distribution of DG sets in use in the Kathmandu Valley of Nepal and estimates air pollution emissions, including black carbon, from these generators.

This report presents an overview and analysis of air quality in Europe from 2003 to 2012. It reviews progress towards meeting the requirements of the air quality directives and gives an overview of policies and measures introduced at European level to improve air quality and minimise impacts.
