This tool from the United Nations Environment Program (UNEP) is designed to provide policymakers and interested individuals and groups with overviews of policy tools and approaches to improving fleet-wide automobile fuel efficiency and promote lower CO2 and non-CO2 emissions from cars, along with case studies that depict these approaches from developed and developing countries.

The tool was created as part of the Global Fuel Economy Initiative (GFEI), which exists to promote improvements in global average automotive fuel economy, as per IPCC and G8 recommendations. More efficient cars will support national and global climate change mitigation efforts if the global light duty vehicle fleet average moves from 8 L/100 km today to 4 L/100 km within the next 4 decades. Emerging and developing economies have a large role to play in this shift as they rapidly motorize. To this end, we continue to raise awareness, present evidence, and offer support, in a way which enables more and more countries to adopt effective fuel economy standards and policies which work in their circumstances and with their fleet.
