In 2015, approximately 12 per cent of all transport fuels used were biofuels in actual terms. The measure achieved an estimated 1.5 million tonnes CO reduction in transport-related greenhouse gas emissions in 2015. It is expected that biofuels will account for 20 per cent (double counting included) of all fuels consumed in transport in 2020. This would consist of first-generation biofuels (seven per cent of all road transport fuels sold) and second-generation biofuels (6.5 per cent of all road transport fuels sold). Biofuels would, in other words, replace 13.5 per cent of fossil fuels in transport in 2020, but as the contribution of second-generation biofuels is considered to be twice that made by other biofuels, the calculated share of all road transport biofuels would be 20 per cent. This means that the related emission reduction in the transport sector would be an estimated 1.6 to 1.7 million tonnes of CO in 2020 depending on the eventual biofuels consumption.
