By the numbers: Challenger 650 emissions reductions from SAF

In simple terms, sustainable aviation fuel (SAF) is an aviation fuel that is made from a substance other than conventional fossil-based sources.  

These non-conventional feedstocks, or ingredients, can include municipal solid waste, forest residues, agricultural residues, isobutanol (corn), and fats/oils/greases. 

Today’s SAF can be safely blended with conventional jet fuel at various ratios. They use the same delivery infrastructure and are compatible with modern aircraft engines. Currently, the highest approved ratio is a 50:50 blend between SAF and conventional fuel. All Bombardier aircraft are certified to operate with this blend.  

As a Challenger aircraft owner or operator, you may be wondering how filling your tanks with SAF will affect your aircraft’s CO2 emissions – and therefore reduce your environmental impact. In the table below, Bombardier engineers have calculated the impacts of using SAF derived from five different feedstocks and synthesized using a variety of production processes. Emission reductions from SAF were calculated in both percentages and in absolute values based on a 30 per cent and a 50 per cent SAF to conventional jet fuel blend. 

To account for various customer mission profiles, scenarios have been developed for Challenger 650 flights of 600 nm, 800 nm (EPD Typical Mission), 1,000 nm, and 2,000 nm distances.
