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.

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.

EEA report: EVs are better for climate and air quality

Green Car Congress

The EEA report ‘ Electric vehicles from life cycle and circular economy perspectives ’ reviews current evidence on electric cars’ impacts on climate change, air quality, noise and ecosystems, compared with conventional cars. The EEA has also published a new briefing on the environmental and climate impacts of transport.

3 Oil Majors That Bet Big On Renewables

Green Car Congress

An analysis of near-term spending plans on renewables by the biggest oil and gas companies shows that real investments in renewable energy will continue to pale in comparison to capex plans for greenfield fossil fuel projects. BIT:ENI) recently unveiled what has been hailed as the most ambitious climate pledge yet by an oil supermajor.

Global Carbon Project: Global carbon emissions growth slows, but hits record high

Green Car Congress

The findings are outlined in three new papers published in Earth System Science Data , Environmental Research Letters , and Nature Climate Change. The decline of coal use in the European Union and United States is overshadowed by surging natural gas and oil use around the world, according to the researchers. over 2018 emissions.

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. But the effects of these efforts seem to be reaching a plateau.
