An Ordinance to provide for the constitution of the Commission for Air Quality Management in National Capital Region and Adjoining Areas for better co-ordination, research, identification and resolution of problems surrounding the air quality index and for matters connected therewith or incidental thereto.

In this report, defined (a) the size of NCAP city airsheds (b) the recommended number of ambient air quality monitoring sites in an airshed (c) the operational sampling frequency to support receptor-based source apportionment studies.

Air pollution presents an increasingly apparent challenge to health and development across the globe. Exposure to PM2.5 is a major health risk and worldwide, an estimated 4.13-5.39 million people died prematurely in 2017 from exposure to PM2.5 pollution. The health impacts of pollution also represent a heavy cost to the economy.

The Commission for Air Quality Management in National Capital Region and Adjoining Areas Ordinance, 2020 was promulgated on October 28, 2020.

To combat rising city air pollution levels, the Government of India launched the NCAP in January 2019 to reduce PM2.5 and PM10 levels by 20-30% by 2024 with respect to 2017 levels.

China, Japan and Korea have deployed a multiplicity of co-operation efforts at different levels of government to promote air quality and curb transboundary pollution.

This brief evaluates the merits of using satellite observations in aiding air quality management. It identifies challenges in the effective application of satellite observations.

This report analyses the implementation of EU air quality legislation at the urban level and identifies some of the reasons behind persistent air quality problems in Europe's cities.

The analysis clearly indicates that even the most stringent emission control measures, if restricted to the Ha Noi area, will not be sufficient to effectively approach Vietnam’s national ambient air quality standards.

In 1998 Beijing began an intensified air pollution control program, and over the last 20 years the city has implemented a series of measures including energy infrastructure optimization, coal-fired pollution control, and vehicle emission controls. These efforts successfully reduced air pollution.
