Singapore Airlines & CAAS partner on “Green Package” flights; biofuels, optimized operations and fuel-efficient A350-950

Green Car Congress

Over the three-month period, flight SQ31 will be powered by a combination of HEFA (Hydro-processed Esters and Fatty Acids), a sustainable biofuel produced from used cooking oils, and conventional jet fuel. In May 2011, CAAS and SIA launched regular ASPIRE flights on the Los Angeles-Singapore route.

PHEVLERs are the Zero CO2 Clean Green Machines of the Future

Green Car Congress

PHEVLERs have lower repair and maintenance costs than conventional internal combustion engine (ICE) vehicles. [ ] Electric drivetrains provide higher reliability and lower costs because they have fewer moving parts and do not require frequent lubrication oil and brake component changes. References.

Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications

Green Car Congress

These 9 combinations became the reference scenarios with defined fuel requirements and GHG emissions. The reference case scenarios assume no change to GHG intensity from current levels. The climate-targeted scenarios included cellulosic biofuel substitution to reduce GHG from light duty transportation to 20% of the reference GHG.
