Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. Schematic overview of the processes by which aviation emissions and increased cirrus cloudiness affect the climate system. Aviation accounts for 3.5% —Lee et al.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1

U-Mich researcher’s first-principles analysis challenges conventional carbon accounting for biofuels; implications for climate policy

Green Car Congress

System boundaries (red line) schematic for liquid fuel carbon balance. For biofuels, because biogenic carbon is automatically credited within a product lifecycle, the boundary effectively excludes vehicle end-use CO 2 emissions. In a paper that could have a significant impact on climate policies for transportation fuels, Dr. John M.

Deutsche Post now automatically offsetting all CO2 emissions from mail transport

Green Car Congress

Starting immediately, Deutsche Post is offsetting any unavoidable CO 2 emissions due to mail transport with investments in internationally recognized and certified climate protection projects at no extra charge. For the last ten years, DHL has transported all parcels for private customers with its climate-friendly “GoGreen” service.

XPrize in Carbon Removal Goes to Enhanced Rock Weathering

Cars That Think

The XPrize Foundation today announced the winners of its four-year, US $100 million XPrize competition in carbon removal. Contestants in the carbon removal XPrize had to demonstrate ways to pull carbon dioxide from the atmosphere or oceans and sequester it sustainably. How Does Enhanced Rock Weathering Remove CO2?

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

Stuart Licht have demonstrated the first facile high-yield, low-energy synthesis of macroscopic length carbon nanotubes (CNTs)—carbon nanotube wool—from CO 2 using molten carbonate electrolysis ( earlier post ). The most compact form of captured carbon is through its transformation to solid carbon.

Study finds limiting warming to 2 °C would require at least a $200/t carbon tax globally

Green Car Congress

Some will suffer greatly from climate change, while others may even benefit. Lloyd Distinguished Service Professor in Economics, and José-Luis Cruz of Princeton University assesses the local social cost of carbon (LSCC) and how that cost aligns with the carbon reduction pledges countries made under the Paris Agreement.
