Yet Another Study Shows EVs Are Cleaner Than ICE & Continue Getting Cleaner

CleanTechnica EVs

EVs are (once again) proving to be cleaner than comparable ICE vehicles. Plus, while ICE vehicles are stuck burning the same fuel for the rest of their serviceable lives, EVs continue to get cleaner as electric grids improve.

CARB: clean fuels replaced more than 50% of diesel used in California in Q1 2023

Green Car Congress

Clean fuels replaced more than 50% of the diesel used in the state in the first quarter of 2023, according to the California Air Resources Board (CARB). This figure provides perspective on the performance of actual quantities of fuel consumed in California. Since compliance began, the program has helped to replace more than 8.6

SwRI engineers help develop post-refinery diesel treatment that overcomes soot/NOx tradeoff for cleaner burning fuel

Green Car Congress

Southwest Research Institute (SwRI) is helping a client develop a simple post-refinery treatment process that reduces exhaust emissions from diesel engines by overcoming the soot/nitrogen oxides (NO x ) reduction trade-off that has plagued engine researchers for decades.

Cleaner fuels have replaced more than 3B gallons of diesel under California Low Carbon Fuel Standard

Green Car Congress

New 2018 data from the California Air Resources Board (CARB) indicates that the state’s Low Carbon Fuel Standard (LCFS) continues to drive production of a growing volume of cleaner transportation fuels for California consumers. The 2018 data also shows fuel producers are in 100% compliance with the LCFS. To date almost 3.3

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

Green Car Congress

Impact of a reduction in initial ice crystal number, as may be caused by reduced soot emissions, on global contrail cirrus properties. In our theoretical estimates, we found that a significant reduction in soot emissions is required to reduce the climate impact of contrails effectively. —Ulrike Burkhardt. —Burkhardt et al.
