Managing Two and Three Wheelers in Asia

MANILA, 24 March 2011 – The substantial increase of two and three wheelers in the Asian region needs to be addressed. In some Asian countries like India and Indonesia, two and three wheelers (motorbikes, bikes, e-bikes and auto-rickshaws) are even expected to outpace the growth of cars. This trend creates a potential risk as more people prefer private individual travel than public transport.

The UNEP Partnership for Clean Fuels and Vehicles (PCFV) and Clean Air Initiative for Asian Cities (CAI-Asia) Center jointly prepared a publication to help inform Asian policy makers on the options for addressing emissions from 2-3 wheelers and including them in future transport planning. Entitled Managing Two and Three Wheelers in Asia, this report analyzes the social and environmental impacts of motorized two and three-wheelers and provides an array of tailpipe and non-tailpipe measures to curb these.

The Partnership for Clean Fuels and Vehicles (PCFV) was launched in September 2002 at the World Summit on Sustainable Development in Johannesburg, South Africa. The PCFV is helping reduce vehicular air pollution in developing and transition countries through the promotion of clean fuels and vehicles. For more information about the PCFV, please visit
