Green Car Congress
JANUARY 23, 2020
Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. As a result, they reported that they had almost completely eliminated HFC-23 emissions by 2017.

The data showed a 50% jump in efficiency each time the panels were cleaned after being left alone for several weeks. The manmade particles are also small and sticky, making them much more difficult to clean off. If cleanings take place every two months, those numbers jump to 25 or 35%. —Michael Bergin. 7b00197.

This is in contrast to the conventional mobile AC system, where the cabin air is directly cooled by the refrigerant HFC-134a, which is ozone safe but has a high GWP. The new SL-MAC system, which is testing the low-GWP refrigerants, is expected to increase vehicle energy efficiency. Andersen, S., Chowdhury, S., Andersen, S., Chowdhury, S.,

Among the findings of the report, “HFC-134a phase-out in the Chinese light-duty motor vehicle sector”, was that, considering the social cost of CO 2 e, up to 1 trillion RMB in costs (US$150 billion) required to address climate change could be avoided through 2050 by transitioning to low-GWP alternative MACs. relative to HFC-134a and 98.6%

The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs may account for an estimated 40% of global warming, increasing the impacts of climate change. —“Revised Proposed Short-Lived Climate Pollutant Reduction Strategy”.
