New data published by the Centre for Research on Energy and Clean Air (CREA) reveals that the overall 2023 air pollution levels in Jakarta were arguably the worst since 2019. Despite improvements between 2020 and 2022, the rise of pollution in 2023 is a notable setback.

The objective of this study is to conduct a comparative analysis of winter pollution PM2.5 levels in major cities in India, Including Mumbai, Varanasi, Patna, Delhi, Chandigarh, Lucknow, and Kolkata, for the years 2022-2023 and 2023-2024.

Bihar's Begusarai emerged as the world's most polluted metropolitan area while Delhi was identified as the capital city with the poorest air quality, according to this report by the Swiss organisation IQAir.

India’s air quality deteriorated in January 2024, as the winter season and low wind speed trapped pollutants near the surface, according to this report by the Centre for Research on Energy and Clean Air (CREA).

Under Section 12 (l) of the Commission for Air Quality Management in NCR and Adjoining Areas Act,2021, the Commission is vested with powers to take all such measures, issue directions, etc., as it deems necessary or expedient for the purpose of protecting and improving the quality of the air in the National Capital Region and Adjoining Areas.

Air pollution is a major threat to health, and the dangers are particularly acute in low- and middle-income countries. However, little is known about how the burden of pollution is spread across the wealth distribution in these countries.

The National Clean Air Programme (NCAP) was launched in India in 2019 and aimed to significantly enhance the air quality in India by 2024 by reducing PM concentration by 20-30 per cent, which in 2022 has been extended to 2026, aiming to have a 40% reduction in pollution levels compared to 2017.

An analysis by the Delhi Pollution Control Committee (DPCC) has revealed a substantial rise in fine particulate matter on Diwali, with a 45 per cent increase in PM2.5 and a 33 per cent increase in PM10, compared to the previous year.

This document summarizes several air quality measurement and modelling methods that can be used to estimate ground-level air pollutant concentrations and presents multiple approaches to monitoring ambient air pollution at different spatial and temporal scales.

Based on the need to establish scientifically robust health-based standards, this working paper evaluates the global best practices for setting or revising air quality standards.
