The Partnership for Clean Fuels and Vehicles (PCFV) has been working with developing and transitional countries to reduce vehicular air pollution through the promotion of cleaner fuels and vehicles. This regulatory toolkit is part of that ongoing campaign and is meant to introduce the need for a systems approach to vehicle emission reduction. A systems approach matches fuels and vehicle improvements – to move towards tighter vehicle emissions regulations.

This toolkit will support developing and transitional countries to introduce requirements for 50 particles per million (ppm) and below sulfur fuels; produce or import lower emitting and more efficient vehicle technologies; establish vehicle emissions control roadmaps; and ultimately improve air quality and human health in these countries. The toolkit will show by examples how to build a regulatory strategy, establish enabling legislation and regulatory standards, and set up enforcement mechanisms. The toolkit will also use specific case examples to illustrate how countries can integrate cleaner fuels and vehicles emission standards.

Many developing and transitional countries – through support of the Partnership for Clean Fuels and Vehicles – have completed the phase-out of leaded petrol, followed by the adoption of targets and roadmaps to introduce lower sulfur fuels. Most of these countries however have yet to introduce vehicle emission standards as shown in the map below. Euro 3 vehicle emission standards will require 150 ppm sulfur in petrol and 350 ppm sulfur in diesel in order to meet emissions limit.
