Short-Lived Climate Pollutants (SLCPs) and other non-CO₂ air pollutants play a significant role in driving near-term climate change and worsening air quality, with direct implications for public health, agriculture, and ecosystems. While carbon dioxide remains the principal focus of long-term climate mitigation efforts, pollutants such as methane, black carbon, hydrofluorocarbons, and tropospheric ozone offer important opportunities for achieving faster climate benefits through targeted emission reductions.

Towards Cleaner Freight in Delhi: Assessment of Interstate Truck Emissions and Mitigation Measures is a joint study by TERI, Indian Institute of Technology Delhi (IIT Delhi) and Air Pollution Action Group (A-PAG). The report provides a holistic evidence-based assessment of interstate freight movement in Delhi-NCR by combining traffic activity, field surveys and real-world emissions measurements. It proposes practical and scalable strategies for reducing freight-related emissions and provides a prioritised implementation roadmap to guide cleaner air, sustainable freight systems and informed policymaking in India.

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

23 Apr 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?

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.

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.

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. It should also be noted that polluted air is the second highest health risk factor in India (Balakrishnan, Dey, Gupta, et al. 2019).
