Study finds COVID-19 lockdown in China brought only slight reduction in PM2.5 and ozone

Green Car Congress

Large improvements of air quality in China during the lockdown have been widely reported, but new research shows that two pollutants harmful to human health—fine particulate matter (PM 2.5 ) and ozone—were only slightly reduced. and ozone were only slightly reduced or barely affected.

Study finds some refrigerants less damaging to ozone layer can degrade to long-lived GHG CF4

Green Car Congress

Some of the substitutes for ozone-damaging chemicals that being phased out worldwide under international agreements are themselves potent greenhouse gases and contribute to warming. Even as we move towards shorter-lived halocarbons for industrial use, during atmospheric degradation they can produce a long-lived atmospheric effect.

Study finds significant slowdown in decrease of NOx emissions in US; implications for air quality management

Green Car Congress

NO x emissions have not been decreasing as expected in recent years (2011–2015) when comparing top-down estimates from satellites and surface NO 2 measurements to the trends predicted from the US Environmental Protection Agency’s emission inventory data, according to a new study by an international team of researchers.

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

Green Car Congress

This gas has very few industrial applications. HFC-23 is a very potent greenhouse gas, with one tonne of its emissions being equivalent to the release of more than 12,000 tonnes of carbon dioxide. As a result, they reported that they had almost completely eliminated HFC-23 emissions by 2017.

Up close and personal with Volkswagen’s e-Golf carbon offset project: Garcia River Forest

Green Car Congress

In 2014, Volkswagen of America announced that starting with the launch of the zero-tailpipe emissions battery-electric 2015 e-Golf ( earlier post ), it would invest in projects to offset the carbon emissions created from the e-Golf on a full lifecycle basis: production, distribution and up to approximately 36,000 miles (57,936 km) of driving.

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

As with the earlier assessment, this study consists of two separate, but related, analyses: greenhouse gas emissions from 2015-2050, and air quality impacts in 2030. First is the continuing decarbonization of the electricity sector and second is the electrification of energy use in transportation and industry.
