The government has commissioned the Swedish Energy Agency to investigate the need for additional instruments to promote the production of biofuels with new technology. In the Budget Bill for 2021, the government has proposed that the requirements in the reduction obligation be tightened. This means that fuel suppliers must reduce greenhouse gas emissions by mixing biofuels in petrol and diesel in greater quantities. The government will also introduce a reduction obligation for aviation fuel. This is one of the instruments decided on to increase the use of biofuels.
