The study has used a systematic selection and analysis procedure to assess each LCA, collating data on the energy and GHG balances of liquid transport fuels and biomass for heat and power. This consistent approach will produce a dataset which can be used to uniquely compare the energy and GHG balances of these two uses of biomass. The representation of collated LCAs as straightforward visual summaries highlights variations within methodology, system boundaries and reporting.
Although this study is ongoing, several issues relating to the lack of transparency of LCA reporting have already become apparent. Common obstacles to reviewing this subject have been in successfully identifying system boundaries, co-product allocation methods and conversion efficiencies used in the LCAs being analysed. Therefore, a set of recommendations for LCA reporting are listed at the end of this report.
