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.

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?

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. They also found higher life cycle global warming emissions than have been previously reported. —Majeau-Bettez et al.

Researchers Determine Process Through Which Hydrocarbon Compounds Emitted by Trees Form Aerosols, With Impact on Human Health and Climate

Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. Global isoprene emissions from plants are estimated at more than 500 teragrams each year. The latest finding can support the development of better models of global gas-aerosol chemistry.
