Controlling the composition of vehicle fuel can reduce pollutant emissions from combustion and enable the use of advanced emission control technologies. Achieving best-practice vehicle emission performance therefore depends on having standards for fuels in place that complement standards for vehicular emissions. But fuel standards alone are insufficient. A compliance program is important to ensure that fuels sold at retail stations meet all the mandated specifications.
Establishing an effective fuel compliance program is challenging because fuel is handled by many parties along the distribution chain: refiners, blenders, pipeline companies, fuel truck operators, and retailers. Intentional addition of off-specification fuel or contaminants can occur during distribution and is difficult to identify unless the fuel is analyzed or the fuel quality is carefully monitored. The challenges are particularly daunting for countries with less mature programs where regulatory authority is unclear and enforcement resources and capacity are limited.
This working paper reviews the experiences of the US, Japan and UK in enforcing motor fuel quality requirements. These three countries all demonstrate a high degree of conformity with their respective fuel standards. The US example illustrates a comprehensive program for ensuring quality of fuel sold in an expansive territory through a distribution system that involves a large number of fuel distributors and retailers. The Japan and UK programs represent successful models for countries with smaller geographical areas: the Japan program relies more on government-funded testing and monitoring, and the UK program depends more on industry self-policing.
The paper summarizes key elements of the respective programs, discusses common elements, and outlines steps in establishing an effective fuel quality inspection program.
