Why EVs Aren't a Climate Change Panacea

Cars That Think

“Electric cars will not save the climate. This is due to the 30 to 40 percent increase in emissions EVs create in comparison to manufacturing an ICE vehicle, mainly from its battery production. Just accounting for miles driven , however, BEVs cars and trucks appear cleaner than ICE equivalents nearly everywhere in the U.S.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

Natural gas does not offer climate benefits compared to gasoline and diesel, and many biofuel pathways do not, either. Drivers of plug-in hybrid electric vehicles rely too much on the gasoline engine for this pathway to be a long-term climate solution, the ICCT said. Source: The ICCT.

PNNL modeling study finds climate benefit for cutting soot, methane smaller than previous estimates

Green Car Congress

Cutting the amount of short-lived, climate-warming emissions such as soot and methane won’t limit global warming as much as previous studies have suggested, according to a new study from the Joint Global Change Research Institute in College Park, Md., More realistic emission reductions would likely provide an even smaller climate benefit.

Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21 st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. These effects redistribute heat and moisture in the atmosphere, impacting climate. —David Keith.

Instead, he and others are trying to invent new climate-control technology that doesn’t further exacerbate the dangers facing the planet’s climate. Winners of the 2021 Global Cooling Prize—both heat pumps—reduce cooling’s climate impact by as much as 80 percent. Still, in the U.S.,

Proof-of-principle of cost-effective methane cracking technology for H2 production without CO2; 50% cleaner than SMR, comparable to electrolysis

Green Car Congress

CO 2 emissions from the ammonia industry alone amount to approximately 200 million tons per year—by comparison, Germany generates around 800 million tons of carbon dioxide per year. The compared hydrogen production technologies were steam methane reforming (SMR) and water electrolysis coupled with renewable electricity.

Canada takes boldest stance on electric vehicles yet

Teslarati

Canada recently released the first details of its flagship policy to achieve one of its most ambitious climate goals to date — by 2035, every new car sold in the country must be emissions-free. In comparison, EVs comprised 19% of new car sales in the UK. In 2021, only 5.6% of new cars sold in Canada were electric.
