All biofuels on the market in Europe and the Netherlands must comply with the sustainability criteria laid down in the Renewable Energy Directive (2009/28/EC). Only sustainable biofuels are allowed to be used for fulfilling the blending target. Compliance with these criteria must be demonstrated through one of the adopted certification systems. These certification systems are controlled by an independent audit. All biofuels produced in the Netherlands fulfil these requirements. The national policy aims to increase the production of biofuels in an effort to achieve the target of renewable energy sources accounting for 10% of the energy use in the transport sector by 2020. In 2016, this share of renewable energy was 7% 109. More than 66% of the energy content is from advanced biofuels. The raw materials for advanced biofuels are waste and residual materials such as used frying fat. Most of the frying fat is imported from other western European countries, Asia (China and Taiwan) and North America. The raw materials of non-advanced biofuels are mainly maize and wheat originating from Europe. The share of renewable electricity, which also contributes to the 10% target, is still small (0.1% in 2016).
