The present techniques relate to facilitating conversion of biosourced triglycerides into fatty acid esters by combining the biosourced triglycerides with a carbonate ester in presence of an alcohol, under catalytic transesterification conditions. A reaction mixture can be heated to a reaction temperature to operate a transesterification of the biosourced triglyceride with the carbonate ester under catalysis of the alcohol thereby forming a single-phase composition comprising the fatty acid esters. The reaction mixture can have a molar ratio of the biosourced triglyceride over the carbonate ester between 1:0.1 and 1:20. Compositions comprising the produced single-phase composition, and optionally an additive, can be used as diesel, jet fuel or lubricant.
