Greenhouse gas reporting for biofuels: A comparison between the RED, RTFO and PAS2050 methodologies
چکیده انگلیسی

Biofuels have been identified as a potential short-term solution for reducing greenhouse gas (GHG) emissions from road transport. Currently, ‘1st generation’ biofuels are produced from food crops, but there are concerns with the indirect effects of utilising edible crops for fuel. There is increased interest in producing ‘2nd generation’ biofuels from woody crops and straw, as these can be grown on lower grade land or do not compete directly with food. In order to ensure that biofuels actually deliver emission savings, the overall GHG balance of producing them must be calculated accurately, and compared with conventional fossil fuels. The GHG balance can vary significantly however, depending on biomass type, the production processes, the indirect effects, and also by the method by which the GHG emission balance is calculated. Currently, in the UK, there are three main GHG methodologies that potentially affect biofuel producers. Each has a different approach to measure GHG emissions from biofuel production, and each provides a different result, causing difficulties for policy makers. This study performs a partial life cycle assessment for bioethanol production from wheat grain and wheat straw to demonstrate the variability of the results between methodologies.


► This study examines the differences between RED, RTFO and PAS2050 methodologies.
► The LCA of bioethanol production from wheat grain and wheat straw are examined.
► The calculation methodology selected has an impact on the overall emission balance.
► Allocation of co-products is the most influential factor on the overall results.
