EEA reports sharp decrease in CO2 emissions of new cars in Europe in 2020

Green Car Congress

2020 car registrations by fuel type in Europe. New car emissions were increasing as recently as two years ago, but the sharp drop last year shows that carmakers respond to CO2 standards. This was 14.5 g (12%) lower than in 2019 and represented the first decrease observed since 2016. in 2019 to about 11% of new registrations in 2020.

Twelve produces first batch of E-Jet fuel from CO2 electrolysis; partnership with USAF; electrifying fuel, not planes

Green Car Congress

Carbon transformation company Twelve (formerly Opus 12, earlier post ) has produced the first fossil-free jet fuel—called E-Jet—from CO 2 electrolysis, demonstrating a scalable, energy-efficient path to the de-fossilization of global aviation. Since you can’t electrify the plane, we’ve electrified the fuel.

CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. The climate effects of hydrogen have been an under-researched topic. The study is the most comprehensive assessment of the climate effect of hydrogen to date. Sand et al.
