A report by a think-tank organization (Policy Exchange) says that widespread use of "sustainable jet biofuels" would result in greenhouse-gas-emission reductions worth about 37.4 million British pounds between 2020 and 2050 in the United Kingdom (UK). A bio-jet fuel can be interpreted as "sustainable" if it is produced from non-food feedstocks, does not lead to deforestation/environmental degradation, and has low carbon/water footprint. The report entitled, "Green-Skies Thinking: Promoting the Development and Commercialisation of Sustainable Bio-jet Fuels" mentions that the adoption of bio-jet fuels under the European Union's Bio-Jet Fuel Blending Mandate, would result in 15% reductions in GHG emissions by 2020, and 60% by 2050. Among the recommendations of the report are: (1) creation of bio-jet fuel demand under the EU Bio-Jet Fuel Mandate, (2) minimizing the cost of deploying sustainable bio-jet fuels, (3) increasing support for companies doing R and D in sustainable bio-jet fuel production, and (4) investing in "methodologies and regulatory bodies needed to ensure that bio-jet fuels are produced sustainably and deliver dramatic life-cycle GHG emissions reductions"..
