The system of testing cars to measure fuel economy and CO2 emissions is utterly discredited. This report analyses the gap between test results and real-world performance and finds that it has become a chasm, increasing from 8% in 2001 to 31% in 2012 and 40% in 2014. Without action this gap will grow to nearly 50% by 2020.

The Indian Ministry of Petroleum and Natural Gas has been considering the possibility of leapfrogging from Bharat Stage (BS) IV emission standards in April 2017 to BS VI emission standards in April 2020. The Parliamentary Committee on Petroleum and Natural Gas has endorsed the idea.

A new paper from the New Climate Economy shows there is large untapped potential for fuel efficiency gains in both aviation and shipping sectors that would cut costs and reduce emissions.

India is currently considering establishing fuel efficiency regulation for new trucks and buses. This process formally started in July 2014 when the Ministry of Petroleum and Natural Gas officially constituted a Steering Committee to guide the regulatory development process (Minstry of Petroleum & Natural Gas 2014).

Analyzes the implications of a growing natural gas vehicle fleet on the emission benefits of the U.S. HDV “Phase 2” greenhouse gas rulemaking, synthesizing data on upstream emissions, vehicle emissions, and efficiency technology.
