Fast action on black carbon, ozone and methane could help limit global temperature rise to 2 degrees C

Green Car Congress

Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and Waste management. Pellet stoves and boilers, using fuel made from recycled wood waste or.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C Source: Shindell et al.

A) shows the base case peak concentrations for O 3 (ozone), ClNO and HCl in parts-per-billion by volume (ppbv). (B) The study, lead by Professor Barbara Finlayson-Pitts shows, however, that the uptake of oxides of nitrogen and HCl on surfaces rather can be an intermediate step on the way to generating more reactive gases.

Life cycle analysis of three battery chemistries for PHEVs and BEVs; environmental impacts higher than expected

Green Car Congress

On a per-storage basis, the team found that the NiMH technology was found to have the highest environmental impact, followed by NCM and then LFP, for all categories considered except ozone depletion potential. A paper on the study appears in the ACS journal Environmental Science & Technology.

Study Finds Current Swedish Biofuels Offer Major Climate Benefits; Biogas from Manure the Best

Green Car Congress

A study by researchers at Lund University in Sweden found that Swedish biofuels produce between 65 and 148% less greenhouse gas emissions than gasoline and diesel, even when direct and indirect land use changes are taken into account. Direct and indirect land use changes were also studied. (A A hat-tip to John!).
