he Ministry of Environment, Forest and Climate Change (MoEFCC), Government of India, launched the National Clean Air Programme (NCAP) in 2019, with the aim to improve air-quality levels in non-attainment cities. NCAP has identified 122 non-attainment cities (cities that violate the national ambient air quality standards).

This report brings together the key insights from an air quality of analysis of 10 cities in South India: Bengaluru, Chennai, Hyderabad, Mysuru, Kochi, Mangalore, Visakhapatnam, Amaravati, Coimbatore and Puducherry. Observations show that PM2.5 and PM10 levels in all cities are well above the recommended World Health Organization limits.

Air pollution is increasingly understood as a global issue, requiring an understanding of pollution sources, transport, and transformation from local to regional to global scales (IPCC, 2013).

This study reviews and compares five databases (three global and two regional) that provide emission estimates for air pollutants in India. These databases include EDGARv5, ECLIPSEv6b, REASv3.2, SMoGv1 and TERI (2016).

New WHO Global Air Quality Guidelines (AQGs) provide clear evidence of the damage air pollution inflicts on human health, at even lower concentrations than previously understood.

This review of the epidemiological literature on fugitive dust indicates the likelihood of significant public health impacts from both short- and long-term exposure to both fine and coarse dust. These impacts are observed in populations that are both near to and distant from the original dust sources.

The aim of this report is to estimate the impact of air pollution on health in contemporary Accra, Ghana. Accra is a city that has experienced rapid growth in the last decades.

Non-exhaust emissions of particulate matter constitute a little-known but rising share of emissions from road traffic and have significant negative impacts on public health. This report synthesizes the current state of knowledge about the nature, causes, and consequences of non-exhaust particulate emissions.

It is evident that as compared to lockdown period, air quality in terms of Air Quality Index has remained ‘Satisfactory’ during modified lockdown period at all the towns except at Jodhpur where it has worsened to ‘Moderate’ Category.

The nationwide Lockdown, in effect since the midnight of 24 March in view of COVID-19 pandemic, has resulted in significant improvement in air quality in the country, as revealed by data analysis and comparison of data for time before enforcement of restrictions.
