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. —Jenny Stavrakou.

Air pollutant emission 2010 limits exceeded in twelve EU Member States; road transport NOx a main factor

Green Car Congress

For the first time, preliminary data recently reported to the EEA by Member States allow a comparison with the legally binding emission limits for 2010 set in the EU NEC Directive. These pollutants can cause respiratory problems, contribute to the acidification of soil and surface water, and damage vegetation. Jacqueline McGlade.

EEA reports finds Europe to exceed NOx emission ceiling, mostly due to road transport

Green Car Congress

Comparison of aggregated EU-27 emission projections and ceilings reported in 2010. The EU-27 and its Member States must meet legally binding limits for four air pollutants set by the National Emission Ceilings Directive (NEC Directive). Most Member States also anticipate meeting their emission ceilings for these pollutants.

Study finds that environmental impact of corn-ethanol E85 is 23% to 33% higher than that of gasoline; environmental problem-shifting

Green Car Congress

In a similar way, the full breadth of impacts attributable to conventional gasoline production, such as natural resource consumption and hazardous pollutant emissions, must also be considered in order to make balanced comparisons to biofuels. This study highlighted the environmental impacts of corn ethanol in comparison with gasoline.

ITF analysis finds that societal costs for electric cars and vans range from €7K to €12K more than fossil-fueled equivalents

Green Car Congress

Sample consumer and societal break-even curves for BEVs, with data points for a compact diesel for comparison. The ITF calculation ignores taxes on fuel (as from society’s point of view these are a transfer rather than a net cost); includes subsidies; and accounts for air pollution impacts.
