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.
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.
Emissions from the diesel engines of these two key types of non-road mobile sources are expected to be significant, and will potentially have strong negative impacts on local air quality and health in India.
This working paper details the differences in fuel specifications for commercial gasoline and diesel fuels in India and the EU, and assesses potential air pollutant emission impacts of these differences.
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.
Surveys diesel engine technologies, costs, pollutant emissions, and efficiency improvements in a manner that can help inform India's transition to more stringent vehicle emissions standards over the next five years.
Concisely sets forth the case for leapfrogging from BS IV to BS VI vehicle emissions standards in India, and states the ICCT's position in favor of expediting progress to Bharat VI.
