Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

Urban CO2 Domes May Enhance May Increase Ozone and PM, With Accompanying Increase in Mortality

Green Car Congress

In a new study published online 10 March in the ACS journal Environmental Science and Technology , however, Stanford University professor Mark Jacobson finds that local CO 2 emissions in isolation may increase local ozone and particulate matter. Articles ASAP doi: 10.1021/es903018m. Mark Jacobson.

Ethanol and Ozone

Plugs and Cars

Yet another reason to think again about the ethanol craze in an article in today's LA Times. There are so many reasons ethanol shouldn't be priority #1 in America's quest for petroleum replacement. I blogged about this previously here. And only electric drive cars can operate truly zero-emission.

Air Quality: Easy to Measure, Tough to Fix

Cars That Think

Ionization can itself create ozone. The state of California has banned such ozone generators entirely. a specific standard of efficiency based on its rating , but this is often combined with unproven UV light, ionization, and ozone technologies that vaguely claim to catch toxins and kill pathogens, even COVID-19. It's true that.

UMD-led study finds China’s SO2 emissions down 75% since 2007, India’s up 50%; India may now be the top SO2 emitter

Green Car Congress

Two maps compare total annual sulfur dioxide amounts for India and China during 2005 (left) and 2016 based on Ozone Monitoring Instrument measurements. The researchers’ second data source was the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite, which detects a variety of atmospheric pollutants including sulfur dioxide.

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.

Life cycle analysis of three battery chemistries for PHEVs and BEVs; environmental impacts higher than expected

Green Car Congress

On a per-storage basis, the team found that the NiMH technology was found to have the highest environmental impact, followed by NCM and then LFP, for all categories considered except ozone depletion potential. Environmental Science & Technology Article ASAP doi: 10.1021/es103607c.
