The Global Renewable Fuels Alliance (GRFA) is a global biofuels federation representing over 90% of the world’s renewable fuels production from 45 different countries.

The objective of this project, undertaken by (S&T)2, was to estimate the global GHG emissions reduction achieved through the production and use of biofuels. This work was first undertaken in 2009 and much has changed since then: biofuel production levels are higher, biofuel production processes have become more efficient and more is known about the GHG emissions of fossil fuel systems.
