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.

Comprehensive efforts are needed to achieve full impact of BS-VI fuel

Mr Sumit Sharma

Despite being a welcome step, the introduction of Bharat Stage VI (BS-VI) grade fuel in Delhi, earlier than the April 2020 deadline, will have only marginal impact on vehicular emission and air quality in the city.

The Economic Times

The use of agricultural residues in power plants can help reduce pollution in the Delhi-NCR region by 8 per cent by 2025, according to a recent study. The study, conducted jointly by TERI and Automotive Research Association of India, suggests several measures that could help in reducing pollution by 2025. It indicated that up to 26 per cent of pollution in the city in summer is caused by internal factors like vehicular emissions and this goes up to 36 per cent in winter.

36% of Delhi’s winter bad air is its own doing: Study

The Times of India

Delhi may be responsible for just 26% of its PM2.5 (microscropic, respirable particles) pollution, a new study released has revealed. This figure goes up to 36% in the winter months. Most of the pollution in this category are attributed to upwind regions beyond the city. These are the findings of the source-apportionment study jointly carried out by TERI and Automotive Research Association of India (ARAI) to derive sectorial contributions to air pollution in Delhi and NCR.

From Oman to NCR towns, 74% of Delhi’s pollution comes from outside: Study

Hindustan Times

At least 74% ultrafine particles (PM2.5) in Delhi's air come from outside the city during summers, a study by TERI has found. They come from NCR towns located further north or west of Delhi and beyond even from as far as Pakistan, Afghanistan and Oman. Delhi also contributes to 40% pollution in Noida and 15% in Gurugram during winter. The two satellite towns are located in Delhi's downwind path. Panipat is located on the upwind path of Delhi and receives only 1% pollution from Delhi.

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.

Advancement of Fuel Quality and Vehicle Emissions Norms to Improve Urban Air Quality in India

September 14, 2014

The health impacts of the deteriorating ambient air quality in urban cities worldwide are of serious concern. According to the World Health Organisation (WHO), one of the top ten causes of death is attributed to air pollution (WHO, 2010); diesel engine exhaust, for instance has been linked with increased lung cancer risk (WHO, 2012). Motor vehicles are one of the major sources contributing to air pollution at local, regional and global scale. India, which has the largest number of megacities in the world, is facing serious air quality problems in its urban areas.

Cooking with cleaner fuels in India: a strategic analysis and assessment

December 7, 2010

The series 'Cooking with cleaner fuels in India: a strategic analysis and assessment' is a collection of four policy briefs that carry findings emanating from a joint research by TERI and All India Institute of Medical Sciences (with support from UNICEF) on healthy cooking fuel options for India. The briefs trace the usage of different fuels in rural and urban households, health implications of using less cleaner cooking fuels, and stakeholder partnerships of governments, funding agencies, industry and consumer groups to accelerate adoption of cleaner cooking fuels.
