    Abstract: The use of at least one cetane improver and at least one fatty acid mono-alkyl ester in which the fatty acid has less than 16 carbon atoms, to reduce the emissions of both particulate matter having a particle size of up to 32 nm and nitrogen oxides, on combustion of a fuel composition in a compression ignition engine; a method of reducing the emissions of both particulate matter having a particle size of up to 32 nm and nitrogen oxides on combustion in a compression ignition engine of a fuel composition comprising at least one fatty acid mono-alkyl ester by providing sufficient of at least one cetane improver in the fuel composition to provide a pre-determined cetane value for the fuel composition and providing that at least 5 percent by volume of the fatty acid mono-alkyl esters in the fuel composition are mono-alkyl esters of fatty acids in which the fatty acids have less than 16 carbon atoms; and a fuel composition comprising at least one fatty acid mono-alkyl ester and at least one cetane improver in which that at least 5 percent by volume of the fatty acid mono-alkyl esters in the fuel composition are mono-alkyl esters of fatty acids in which the fatty acids have less than 16 carbon atoms.
