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. For comparison, columns over the same time periods are shown for 2019. Bauwens et al.

coal, oil, natural gas, and biomass). Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. Across scenarios, we found the more cars that transitioned to electric power, the better for summertime ozone levels. Seasons and times of day. 2019.04.003.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? Research takes a long time.

German-Chilean consortium investigating new ways of reducing arsenic in copper concentrates: ReAK

Green Car Congress

In Chile, the current procedure is to capture the gas, dissolve it in sulfuric acid and then transform it into solid calcium arsenate or calcium arsenite in a process known as precipitation. However, climate change has caused an increase in rainfall in recent years, which now raises the issue of environmental contamination.

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. CO 2 remains in the atmosphere for up to a century.

What is the Electric Vehicle Approved (EVA) Scheme?

Green Charging

By the end of 2019, an additional 130 dealerships received the accreditation, and more are expected to be approved this year. Global warming plays a role in thinning the ozone layer, thus permitting harmful rays’ penetration to the earth. Address climate emergency- the climate is changing rapidly. Wrapping up.
