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. —Ulrike Burkhardt.

Achates near-zero heavy-duty opposed-piston diesel enters fleet service; compliant with 2027 NOx levels

Green Car Congress

It is the only diesel engine operating on the road capable of meeting CARB’s 2027 regulation, which requires a 90% reduction in emissions of NO x compared to current standards. The catalyst light-off mode delivers the capability that allows Achates to manage extremely low engine-out NO x and also very high exhaust gas temperatures.

CMU study finds SOA levels in cities like LA will remain high despite cleaner cars; nonlinear relationship between SOA and NOx

Green Car Congress

The findings of a study by researchers at Carnegie Mellon University, with colleagues at UC Berkeley, suggest that changing atmospheric NO x levels over the next two decades will likely significantly reduce the effectiveness of stricter new gasoline vehicle emissions standards in reducing concentrations of secondary organic aerosol (SOA).

Building materials recycler switches fleet to Neste renewable diesel

Green Car Congress

After examining electric-driven solutions to the carbon and emissions footprint of Argent’s fleet, it became clear the best fit would be low-carbon, sustainable, bio-based renewable diesel fuel, primarily due to the rugged duty cycles of its trucks and equipment. We have noticed that the exhaust appears cleaner and seems less toxic.

Australia introduces its first exhaust rule but makes all the mistakes the US did

Baua Electric

Photo by Marcus Reubenstein on Unsplash Australia will introduce a bill to parliament this week containing its first-ever vehicle emissions rule, a huge step forward for the country. Automakers often bring their dirtiest cars to Australia, and don’t offer better and cleaner electric models in the country.
