Emission Norms India


The foundation for automotive emission standards in India since the early 2000s is contained in two reports from the Indian Planning Commission. The National Auto Fuel Policy announced on October 6, 2003, envisioned a phased program for introducing Euro 2-4 emission and fuel regulations by 2010. In order to establish limits beyond Bharat Stage IV, the Indian Planning Commission established an Expert Committee in 2013 to draft an updated Auto Fuel Policy, Auto Fuel Vision and Policy 2025, that was published in May 2014.

While legislators are not required to adhere strictly to the recommendations contained in these reports, they serve as a starting point for subsequent legislative action to establish the implementation schedule and other details of automotive emission standards. The implementation schedule of EU emission standards in India is summarized below
