Decarbonized Aviation Engines

Solving global warming takes more than just trees

The British engineering firm Rolls-Royce plans to eliminate aviation carbon emission by 2050. The company announced that it would modify its jet engines to run on renewable fuels. To accomplish its environmental goals, Rolls-Royce will introduce its sustainable fuels in 2023.

Sustainable aviation fuel (SAF) will be used in this endeavor. Unfortunately, the decarbonization process is slow; it is expected that the new fuels will make up only 10 percent of total consumption by 2030. SAF is made from non-fossil sources. This means that the emissions from SAF will not contribute to atmospheric CO2. The fuel formula will include food and forestry waste; purpose-grown energy crops such as willow and algae are included in the fuel's composition.
