Transport fuels is an area with high reliance on European standardization. Common and precise methods of sampling and testing, to avoid double sampling and testing in evaluating the quality of a product, are extremely essential when it comes to trading fuels. The development of European Standards is an important element in providing these common methods and ensuring that European consumers and businesses are provided with safe and reliable fuels, while considering the environment (e.g. emissions). European standardization also plays a role in ensuring clear consumer information on the compatibility between new alternative fuels and cars, by setting clear and simple labelling requirements.
Biofuels are also used as a blend component of regular fuel. More information on the European standardization work in the area of biofuels can be found in the section on renewable energy sources.
