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.

In a recent study prepared by the Automotive Research Association of India and TERI, it has been highlighted that close to 3 million households in the National Capital Region use biomass fuel. It is noteworthy that the use of traditional stoves and burning of solid biomass is not restricted to cooking only. It is also used for multiple purposes such as space heating, keeping the flies/insects away in the animal sheds, warming food/water for preparing an animal feed.

How air pollution in Delhi is affecting our children

November 26, 2018

| Hindustan Times

Delhi is under severe stress, thanks to urbanisation, increasing population and alarming levels of pollution. Studies have proved that transportation, industrial and residential sectors are the largest polluters, and that the citizens are exposed to high levels of nitrogen oxides, ozone, black carbon and particulate matter. The 2015 Global Burden of Disease report attributes about 1.09 million deaths in India to PM 2.51 and identifies air pollution to be among the top 10 health risks in the country.

With a 28% share in Delhi's particulate matter concentration during winters, the transport sector also provides a huge scope to introduce targeted interventions to curb air pollution. While the government has tightened emission norms and introduced cleaner fuels, the expected results have not been observed in the city's air quality. Studies have shown that around 60% of vehicular air pollution in India can be attributed to 20% of vehicles, the ones that are poorly-maintained or, simply, old.

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.
