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. Transportation.

Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Even if true though, the use of blue hydrogen appears difficult to justify on climate grounds. Howarth and Jacobson (2021).

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.

Los Angeles-Long Beach Port trucking company replacing entire diesel truck fleet with near-zero emissions natural gas trucks, RNG

Green Car Congress

(TTSI) is replacing its entire diesel trucking fleet with near-zero emission natural gas trucks, which it plans to fuel with carbon-negative renewable natural gas (RNG). TTSI’s 40 new near-zero emission heavy-duty compressed natural gas (CNG) trucks reduce this type of emissions by 90%.

Study: annual climate impact of wild pigs could be greater than 1.1M cars

Green Car Congress

The researchers used predictive population models coupled with advanced mapping techniques to estimate the climate damage wild pigs are causing across five continents. Since soil contains nearly three times as much carbon than in the atmosphere, even a small fraction of carbon emitted from soil has the potential to accelerate climate change.

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 £1.28

ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. We know from Olmer et al.
