UCL-led study finds climate impact caused by growing space industry needs urgent mitigation

Green Car Congress

The rapidly growing space industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL and published in the journal Earth’s Future as an open-access paper. The space industry is one of the world’s fastest growing sectors.

Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). This despite evidence that suggests air pollution impacts from the transportation sector exceed those from greenhouse gases. …

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather?

Study Highlights the Importance of Considering Climate Effects of Non-CO2 Emissions from Transport in Mitigation Strategies and Policies

Green Car Congress

Radiative forcing from the global and US ORT and PG sectors. The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate.

National Research Council report finds it unlikely the US will meet cellulosic biofuel mandates absent major innovation or a change in policies

Green Car Congress

One opportunity to reduce the cost of biofuels is to reduce the cost of bioenergy feedstock, which constitutes a large portion of operating costs, and increase the conversion efficiency from biomass to fuels. Such land conversion may disrupt any future potential for storing carbon in biomass and soil. Barriers and opportunities.

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

Low-input cultivation of perennial plants, e.g. from short-rotation forestry and grasslands, may be an effective source of cellulosic biomass and provide environmental benefits (reduced pollution and lower greenhouse gas emissions). However very few studies include water use impacts.
