Much before air pollution emerged as a critical health and environment issue in India, we developed state-of-the-art capacities for studying air quality. Our research focusses on a range of issues, including ambient air quality and apportionment of contributing sources , indoor air quality assessment for urban and rural households, regional scale assessment, impacts on health and agriculture, and capacity building of stakeholders for better management. Our research and analyses have been taken into account by policy makers for improvements in various standards and policies.

Dr Vibha Dhavan, Director-General, TERI said that not just reducing activities that cause pollution, such as excessive use of air conditioners, vehicles, construction work but even manufacturing in factories needs to be controlled by way of controlled purchase and making reusable items instead of use-and-throw ones.

The air quality management commission has been set up by the Government of India and has started its work; ultimately everything is dependent on state coordination, said Mr R R Rashmi, Distinguished Fellow and Programme Director, TERI.

Air is bad outside? You might not know that it’s probably bad inside as well.

Regulating indoor air quality is "very important" but developing a framework will be challenging, Mr R Suresh, Senior Fellow and area convenor of the Centre for Environment Studies in TERI, said.

Centre-state coordination must for cleaner air

The successful use of briquettes/pellets made from crop waste as a substitute for coal in thermal power plants offers a viable solution. A designated agency should buy the waste at the mandis where the crops are brought for sale. The Central Government, through its financial institutions, should provide credit for buying crop waste. It may then be given to private parties for conversion into pellets and supply to the power plants.

Could the National Capital Region serve as a control region for effective air quality management in Delhi?

November 4, 2020

Air pollution does not follow administrative boundaries, and needs to be tackled at the regional "airshed" level at which it is caused. Identifying the appropriate candidates for airshed management requires scientific analysis using systematically developed emissions inventories and dispersion models to simulate the impact of the estimated emissions on air quality.

Emissions control in thermal power stations: Issues, challenges, and the way forward

February 21, 2020

As per TERI's analysis, of the total environmental pollution in 2016, the power sector reportedly accounted for 51% of sulphur dioxide (SO2), 43% of carbon dioxide (CO2), 20% of oxides of nitrogen (NOx), and 7% of PM2.5 emissions.

Crop residue management: Solution to achieve better air quality

January 30, 2020

Residents of different cities (probably villages too) of India breathe some of the least healthy air of the globe. During 2017, about 76.8% of the population of India were exposed to annual population-weighted mean PM2·5 greater than the limit recommended by the National Ambient Air Quality Standards (NAAQ: 40 mg/m3) (Balakrishnan, Dey, Gupta, et al. 2019). Over last five years, the annual population-weighted mean ambient PM2·5 concentrations were significantly higher over the Indo- Gangetic Plain (IGP) region in comparison to other parts of the country.

Fleet Modernization: A solution to achieve better air quality

December 10, 2019

India's transport demand has grown from a total of 5.3 million in 1981 to 230 million in 2016, with two-wheelers and cars having 73% and 14% share, respectively. Commercial vehicles though constitute only about 5% of the total fleet, contribute to nearly 80% of total PM emissions.

Phase-wise implementation of fleet modernization (transforming pre BS-IV commercial vehicles to BS-VI) would lead to a 40-80% reduction in PM and NOx emissions from the sector by 2025.

Opportunities with Biofuel: Co-benefit of Air Quality Improvement

December 5, 2019

While biofuels have been discussed as one of the ways to reduce air pollution, changing the process of bio-diesel production is needed to reduce tailpipe emissions of nanoparticles. These are lesser known pollutants even more harmful than PM2.5 and PM10.

Position paper on Improving Inspection and Maintenance System for In-use Vehicles in India

March 3, 2017

The transport sector is an important contributor to pollution in cities. The sector accounts for a significant contribution in PM2.5 concentrations in most Indian cities. In Bengaluru, the sector accounts for almost 50% of PM2.5 concentrations.
