Studies find global COVID-19 lockdowns have significantly reduced PM2.5 and NO2 pollution, but ozone up

Green Car Congress

Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. Ozone is harmful to humans at ground-level, causing pulmonary and heart disease. —Guy Brasseur.

Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

pollution is falling, harmful ground-level ozone pollution is on the rise, especially in large cities. Ozone is the main ingredient in smog and has been studied since it began choking cities in the US in the early 1950s. Both NO x and VOCs are emitted from fossil fuel combustion, and VOCs can also be emitted from industrial sources.

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

The California Air Resources Board released GHG emissions data for 2018 showing that emissions remain below 1990 levels but are effectively flat compared to 2017, while the economy grew by 4.3%. million metric tons in 2017. million metric tons between 2017 and 2018, the first such decline since 2013. tons per person to 10.7

Emissions of potent GHG HFC-23 have grown, contradicting reports of huge reductions

Green Car Congress

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. This gas has very few industrial applications. This would have been a big win for climate.

ICCT study finds that transitioning to low-GWP MAC refrigerants in China could avoid up to US$150B in costs

Green Car Congress

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%

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

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”.
