The Global Fuel Economy Initiative (GFEI) – a partnership of the International Energy Agency (IEA), the United Nations Environment Programme (UNEP), the International Transport Forum of the OECD (ITF), the International Council on Clean Transportation (ICCT), the Institute for Transportation Studies at the University of California-Davis, and the FIA Foundation – works to secure real improvements in fuel economy and the maximum deployment of existing fuel economy technologies in vehicles across the world. The Initiative promotes these objectives through shared analysis, advocacy, and the Cleaner, More Efficient Vehicles Tool for in-country policy support.

Workshop on heavy-duty vehicle fuel efficiency regulations

An international workshop on heavy-duty vehicle (HDV) fuel efficiency regulations in India was held on 29 April 2015 in New Delhi. The event was co-hosted by the Indian Petroleum Conservation Research Association (PCRA) and the International Energy Agency (IEA) and organised with the co-operation of the International Council on Clean Transportation (ICCT). A follow-up meeting with government representatives and international experts was held on the following day at the PCRA headquarters.

Benchmarking fuel economy

The latest analysis of global fuel economy trends concluded that, while global average fuel economy was improving, more needs to be done to meet the ambitious yet realistic GFEI target to halve the specific fuel consumption of new passenger light-duty vehicles (in Lge/100km) by 2030.

Benchmarking fuel economies
The update
, published in December 2014, adds two more years (2012 and 2013) and three more countries to earlier analyses (GFEI, 2011 and GFEI, 2013) and includes substantial methodological changes. The normalisation to the NEDC test cycle is the main methodological revision. It aims to deliver more robust and internationally comparable results. Read more...
