Motor vehicle emission regulations and fuel specifications

This report summarises changes in worldwide legislation and regulations governing motor vehicle emissions, fuel specifications and fuel consumption. Specifically, it details current and proposed legislation on emissions limits and emissions testing, vehicle inspection and maintenance programmes, plus legislation aimed at controlling in-service emissions performance, fuel consumption and carbon dioxide emissions. It also includes information on fuel specifications and characteristics. The report should be read in conjunction with Part 2, which was originally issued as a separate volume in 1997. It is intended that Part 1 will be updated regularly, whereas Part 2 - a comprehensive reference document - will be revised at longer term intervals.
