Study finds global emissions of several banned ozone-destroying CFCs are increasing

Green Car Congress

New analysis has found increasing emissions of several ozone-depleting chemicals despite their production being banned for most uses under the Montreal Protocol—and a loophole in the rules is likely responsible. According to the researchers, emissions from these CFCs currently do not significantly threaten ozone recovery.

Oregon EQC approves Clean Trucks Rule

Green Car Congress

Under the ACT Rule, Oregon requires medium- and heavy-duty vehicle manufacturers to sell zero-emission vehicles as a certain percentage of sales, beginning with the 2025 vehicle model year. In Oregon, heavy-duty trucks and buses are responsible for nearly 23% of total transportation sector greenhouse gas emissions.

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

There are widespread policy assumptions that the phase-out of gasoline and diesel internal combustion engines will over time lead to much reduced emissions of Volatile Organic Compounds (VOCs) from road transport and related fuels. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g., Lewis, Marvin D.

Study first to quantify amount of US pollution resulting from Chinese manufacturing for exports

Green Car Congress

Chinese air pollution blowing across the Pacific Ocean is often caused by the manufacturing of goods there for export to the US and Europe, according to findings of a new study to be published this week in the Proceedings of the National Academy of Sciences (PNAS). When you buy a product at Wal-Mart, it has to be manufactured somewhere.

UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). Climate and the Ozone Layer. Source: UNEP. Click to enlarge.

DOE HPC4Mfg program funds 13 projects to advance US manufacturing; welding, Li-S batteries among projects

Green Car Congress

A US Department of Energy (DOE) program designed to spur the use of high performance supercomputers to advance US manufacturing has funded 13 new industry projects for a total of $3.8 GM and EPRI. Sepion’s polymer membrane technology provides a counterpoint, yielding long-lasting lithium-sulfur cells.
