MIT study finds including non-CO2 emissions from synthetic aviation fuel in lifecycle analysis of climate impact can lead to decrease in relative environmental merit; need for a holistic analysis framework

Green Car Congress

Aviation climate change impacts pathway. A new study by researchers at MIT has found that factoring the non-CO 2 combustion emissions and effects into the lifecycle of a Synthetic Paraffinic Kerosene (SPK) aviation fuel can lead to a decrease in the relative environmental merit of the SPK fuel compared to conventional jet fuel.

DLR: cleaner aircraft emissions reduce the climate impact of contrail cirrus

Green Car Congress

Fewer soot particles in the exhaust stream of aircraft reduces the formation of ice crystals and therefore the climate impact of the resulting contrail cirrus. The results are published in an open-access paper in the Nature Partner Journal (npj) Climate and Atmospheric Science. Burkhardt et al. —Ulrike Burkhardt.

DNV GL paper suggests near-term success for LNG in shipping; alternative fuel mix to diversify over time

Green Car Congress

Well-to-Propeller GHG emissions results for marine alternative fuels. DNV GL has released a position paper on the future alternative fuel mix for global shipping. The global merchant fleet currently consumes around 330 million tonnes of fuel annually, 80-85 per cent of which is residual fuel with high sulfur content.
