Topics / Vehicle emissions control in India

If India is to reap the full social and economic benefits of increased mobility, the country must find effective ways to address the negative consequences of rising transportation activity, such as declining air quality, increasing reliance on fossil fuel imports, and climate change.

The ICCT is completing a long-term study of India’s program to regulate and control emissions from light-duty and heavy-duty vehicles—cars, motorcycles, trucks, and buses. Below is a collection of materials related to that study.

Evaluates alternative regulatory pathways for India’s agricultural tractors and construction equipment on the basis of air pollutant emissions.

Current non-road regulatory programs lag behind comparable programs for on-road diesel engines, and are not stringent enough to compel the use of the best available technologies for the control of PM and NOx emissions.

The maximum benefits of a fleet modernization program can be achieved by conducting a subsidized scrappage program along with early adoption of BS VI standards starting as soon as 2019.

The proposed BS VI standards are far-reaching in scope and incorporate substantial changes to existing Bharat Stage III and IV emission standards. Of particular note is the tightening of particulate matter (PM) mass emission limits and the introduction of particle number (PN) limits for light- and heavy-duty vehicles (LDV, HDV) fitted with gasoline direct injection (GDI) and compression ignition (CI), or diesel, engines.
