The report explores the potential of using biofuels to replace petrol and diesel in Sweden. By increasing the use of biofuels, Sweden could meet its energy needs and reduce CO2 emissions. Biofuels could be used for heat and electricity production, which is more effective in reducing CO2 than using them for vehicles. Exporting biofuels to other countries could also help reduce CO2 emissions. However, the estimates have uncertainties and depend on the location of biofuel resources and potential users.
