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.

Air Pollution in India: Major Issues and Challenges

This article foregrounds the challenges India is currently facing in reducing air pollution and bringing the level of air quality to a certain standard. It also discusses solutions that could be adopted to combat the national crisis.

The source appropriation study, a first for Haryana is being carried out by The Energy and Resources Institute. Mr Ved Prakash Sharma, Senior Manager -Labs, one of the TERI’s lead researchers in the study said the data collection for the study is completed. They will carry out validation and interpretation of the information, upon which a detailed road map will be drawn considering all possible measures for air quality improvement. These measures will be classified into short and long term, with priority to low-cost measures with maximum benefits.

Clearing The Air: Combating pollution for a healthier global urban future

The path to significant air pollution reduction is filled with challenges, requiring comprehensive policy reforms, stringent regulations, and active public-private sector collaborations. However, effective strategies aimed at mitigating air pollution offer a ray of hope in this scenario. Steps such as strengthening vehicle emission standards, promoting renewable energy, and improving public transportation infrastructure are crucial. However, the responsibility lies not only with the authorities.

Gasping for breath: What is India doing about its air pollution crisis?

June 14, 2023

India has implemented a variety of regulations aimed at various sources of air pollution, ranging from industry to road traffic. Despite this, its air quality has steadily deteriorated, to the degree of today's public health catastrophe.  The difficulty in achieving a lasting impact from these initiatives is multi-faceted said Mr Suresh Ramasubramanya Iyer, Senior Fellow and Area Convenor, Centre for Environmental Studies, The Energy and Resources Institute (TERI).

Harder to breathe: Mumbai wheezes its way to becoming pollution capital

Business Standard

The Swiss air tracking index, IQAir, ranked Mumbai and the Mumbai metropolitan region as India's most polluted urban centre. Mumbai's AQI ranged between 200 and 400 on Most days in January and February. Due to La Nina, the air transfer between sea and land, which used to happen every two to three days, slowed down to a seven to 10-day cycle this winter, says Dr Anju  Goel, Fellow, Earth Science and Climate Change Division, TERI.

Soon, Delhi's air pollution sources to be available in real time

The Hindu

A "super site" and mobile laboratory (a lab-on-wheels capturing air pollution readings and sources from various parts of the city) are set to be opened by the chief minister, Mr. Arvind Kejriwal. These were used for the "real-time source apportionment study," under which data on Delhi's air were collected. A model (software) was created giving sources of air pollution by using air from the surroundings as input. The source apportionment study is being done by IIT Kanpur, IIT Delhi, TERI, and IISER Mohali at the cost of around Rs 12 crores for the Delhi Pollution Control Committee.

A PM2.5 and PM10 source apportionment study, with a focus on identifying local polluters, will take place for the first time in Gurugram, Sonipat and Panipat. The Haryana State Pollution Control Board (HSPCB) has given its nod to the Automotive Research Association of India (ARAI) to conduct this study. TERI is conducting a similar study in Faridabad.


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.

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.
