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 source , 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.

In April 2025, Delhi experienced an intense heatwave, recording the hottest day of the year so far and the warmest night in six years. It also marked the highest maximum temperature for April in the last three years. These conditions, now becoming more frequent and severe, are a stark reminder of the urgent need to address heat-related risks.

Bridging the Gap: The Urgent Need for Enhanced Public Transport in India’s Air Quality Mission

Dr Anju Goel

A cornerstone of the National Clean Air Program (NCAP) is that it prioritizes micro-level interventions like improving urban infrastructure, monitoring networks, and sustainable practices. The XIV Finance Commission allocated ₹36,000 crores to support city specific action plans tailored to their challenges. Despite this funding, achieving NCAP’s ambitious targets necessitates tackling a major source to urban air pollution- Road Transport.

दिल्ली में बढ़ता वायु प्रदूषण संकट: बदलते स्रोतों, AQI रुझानों और स्थानीय-क्षेत्रीय योगदान का गहन विश्लेषण

Dr Anju Goel

दिल्ली की बिगड़ती वायु गुणवत्ता ने जीवन स्तर को गंभीर रूप से प्रभावित किया है, जिससे निवासियों को गंभीर स्वास्थ्य समस्याओं और दैनिक कठिनाइयों का सामना करना पड़ रहा है। यह स्थिति अब एक बड़े सार्वजनिक स्वास्थ्य संकट में बदल चुकी है। पिछले दो दशकों में प्रदूषण के स्रोत बदल गए हैं, और कई उपायों के बावजूद शहर खतरनाक वायु गुणवत्ता से जूझ रहा है। दिल्ली में वायु प्रदूषण इतना व्यापक हो चुका है कि यह निवासियों के स्वास्थ्य, कल्याण और भविष्य के लिए खतरा बन गया है।

Shifting Gears Towards Cleaner Air: Modernizing Urban Fleets for a Greener Future in India’s Million-Plus Cities

April 23, 2025

In response to extreme levels of fine particulate air pollution in India and the increasing recognition of its adverse health impacts, the Indian government launched the National Clean Air Programme (NCAP) in January 2019 (Ministry of Environment, Forest, and Climate Change, 2019). The NCAP aims to improve air quality in 131 cities, including non-attainment cities and Million Plus Cities across 24 states through a multi-stakeholder engagement approach. All 131 cities have developed city Action Plans (CAPs) and are being implemented by Urban Local Bodies.

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.
