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.

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.

MIT team finds aviation emissions’ impacts on air quality larger than on climate

Green Car Congress

Researchers at MIT have determined that growth in aviation causes twice as much damage to air quality as to the climate. Aviation emissions are an increasingly significant contributor to anthropogenic climate change. Aviation emissions are an increasingly significant contributor to anthropogenic climate change.

UCS: ride-hailing trips can produce nearly 70% greater emissions compared to private car trips

Green Car Congress

A new report by the Union of Concerned Scientists (UCS) finds that the rising use of ride-hailing services is increasing carbon emissions, with ride-hailing trips producing nearly 70% greater emissions compared to the trips they are replacing. Error bars for bus and rail emissions represent variability among cities. Source: UCS.

Novel adaptation for existing blast furnaces could reduce steelmaking emissions by 88%; closed-loop carbon recycling

Green Car Congress

Researchers from the University of Birmingham have designed a novel adaptation for existing blast furnaces that could reduce CO 2 emissions from the steelmaking industry by nearly 90%. billion in 5 years while reducing overall UK emissions by 2.9%. If implemented in the UK alone, the system could deliver cost savings of ÂŁ1.28

CARB approves 2022 Scoping Plan; aggressive targets for reductions in petroleum use, air pollution and greeenhouse gas emissions

Green Car Congress

The California Air Resources Board last week approved the final proposed 2022 Scoping Plan ( earlier post ), a roadmap to reduce demand for petroleum by 94%, cut air pollution by 71%, reduce greenhouse gas emissions 85%, and reach carbon neutrality by 2045. Fuels: the energy source used to power vehicles and the facilities that produce them.
