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.

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.

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

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. In the journal Joule , Harvard researchers report the most accurate modelling yet of how increasing wind power would affect climate.

Ninth annual Green Innovation Index finds California light-duty vehicle emissions spike; major challenge to 2030 climate goals

Green Car Congress

If current rates of decline continue through 2020, the state will need to reduce emissions at a rate of 4.97% each year in the decade between 2020 and 2030, and produce even steeper declines in the period from 2030 to 2050, if it is to meet current climate goals. In 2015, California increased renewable electricity to 21.9%

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.

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.

The environmental impact of electric cars

Drive Electric

Fully electric vehicles are zero-emission and their batteries can be charged using renewable energy. This is cleaner and better for the environment than producing petrol and diesel. In comparison – a combustion engine car’s brakes convert kinetic energy into wasted heat to slow the vehicle. What is regenerative braking?
