Transport biofuels |
---|
Transport accounts for 25% of the UK's carbon dioxide (CO2) emissions. Low carbon fuels such as biofuels are expected to play a part in reducing CO2 emissions from the transport sector. Biofuels are produced from biomass (plant or animal material). They are renewable and have typically lower lifecycle CO2 emissions than petrol or diesel. 'Second generation' biofuels may offer even lower CO2 emissions, but these are not yet commercially available. Although biofuels can provide carbon savings, some groups are concerned about the environmental and socio-economic impacts of biofuel feedstocks, especially in developing countries. This POSTnote examines the issues relating to current and future transport biofuels.
