Integrating refrigerants with low global warming potential into India’s light vehicle fuel efficiency standards

India’s light vehicle fuel consumption standards currently ignore both direct and indirect emissions from mobile air conditioning (MAC) systems. The MAC does not operate during the official tests that determine compliance and neither climate-friendly refrigerants nor MAC efficiency improvements are included in the off-cycle credits system offered under the standards. …

Fuel economy standards and zero-emission vehicle targets in Chile

This policy update summarizes the steps taken by Chile in relation to its new energy efficiency law and its targets for zero-emission vehicles (ZEVs), and it analyzes the implications of these two policies for the decarbonization of fleets regionally and internationally. In recent years, Chile has created several public policies …

The potential of 48V hybrids in India’s light-duty vehicle market

There is increasing interest in hybrid vehicles globally and India is no exception. With passenger car CO2 standards expected to become more stringent in the coming years, manufacturers are likely to turn to 48V hybrids for the Indian market, as is already happening in Europe.
