Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

The study was published in the journal Atmospheric Environment. Eleven years have passed since the last time a similar study was conducted, and there has been a strong growth in the aviation sector since then, particularly in Asia. Aviation accounts for 3.5% —Marianne Tronstad Lund, co-author. 2 ), and NO x (17.5?mW?m Prather, R.

Fast action on black carbon, ozone and methane could help limit global temperature rise to 2 degrees C

Green Car Congress

Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and Extraction and transport of fossil fuel. for 2030 and beyond.

Study finds global emissions of ethane and propane underestimated by more than 50%

Green Car Congress

When ethane and propane—the most abundant non-methane hydrocarbons (NMHC) in the atmosphere—mix with nitrogen oxides from vehicles and power plants they form tropospheric ozone—a key component of smog and directly linked to increases in mortality.

Further, indoor exposure to household air pollution from the use of solid fuels for cooking and heating was responsible for 2.9 million deaths, 64% were in Asia, especially China and India.

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? about 0.6 °C.

Study Finds Current Swedish Biofuels Offer Major Climate Benefits; Biogas from Manure the Best

Green Car Congress

The fuels studied were: biogas from sugar beet, ley crops, maize and waste products in the form of household waste, industrial waste and manure; biodiesel from rapeseed; ethanol from wheat and sugar beet; and ethanol from Brazilian sugar cane. There is room for all, and all are needed to develop alternatives to fossil fuels.
