Air

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.

Air pollution causing heart diseases

Dr Kanhaiya Lal

Air pollution is one of the five leading causes of death worldwide. An eminent cardiologist associated with the Harvard Medical School presents terrifying statistics on worldwide deaths linked to air pollution. Air pollution-linked illness was found to be seven crores globally, and 70 lakh people lost their lives, according to the WHO. Out of these deaths, about 24 lakh deaths were associated with Ischemic Heart Disease (IHD), and 13 lakh deaths were due to heart strokes, that is, a total of 37 lakh deaths from heart-ailments.

TERI Energy & Environment Data Diary and Yearbook (TEDDY) is an annual publication brought out by The Energy and Resources Institute (TERI) since 1986. TEDDY presents latest information on energy supply sectors (coal and lignite, petroleum and natural gas, power and renewable energy sources), energy demand sectors (agriculture, industry, transport, residential, and commercial sectors), and environment (local and global). It seeks to support policy research and decision-making by providing policymakers and researchers with the data which can be used to develop actionable solutions.

What are the worst polluters in Delhi NCR? Here’s what a TERI report says

The Indian Express

As pollution levels soar, what are the main contributors to air pollutants in the National Capital Region (NCR)? A draft report on a 2021 emission inventory the latest available answers this question, reiterating some of what earlier such inventories have found and marking a few departures. An emission inventory, usually prepared for a particular year, quantifies emissions from different sources for a city or region for that year. The 2021 draft report was prepared by The Energy and Resources Institute (TERI).

Delhi requires another 60 per cent reduction to meet the National Ambient Air Quality Standards for PM2.5. Similar trend is reflected in the winter pollution, even though the winter peaks have declined the average level for the winter months have stayed elevated and also seen an increase. These data points are based on the CSE's analysis from different bodies, including the IITM, TERI-ARAI, CPCB's real-time air quality data and traffic data from Google map, among others.

To tackle pollution, an airshed level air quality management policy is needed; a strategy for GRAP has to be made for the whole year

Dr Anju Goyal, Associate Director, Air Quality Research, TERI, says that air quality depends mainly on emission sources and meteorological conditions. Although policies have been made to control emissions, their implementation is still questionable. Also, the wind speed in October this year is 35% less than last year, due to which the conditions for dispersion of pollutants are not favorable.

Dr. Vibha Dhawan, member of the Commission for Air Quality Management in the National Capital Region and Adjacent Areas and Director General of TERI, says that crop production has increased significantly in the last few decades. But the number of harvesters we have has not increased in the same proportion.

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

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.
