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.

CU Boulder study: routine household activities generate air quality on par with major polluted city

Green Car Congress

Furthermore, airborne chemicals that originate inside a house don’t stay there: Volatile organic compounds (VOCs) from products such as shampoo, perfume and cleaning solutions eventually escape outside and contribute to ozone and fine particle formation, making up an even greater source of global atmospheric air pollution than cars and trucks do.

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

in 2018 (2000-2018 average year-over-year increase is 6.8%), continuing the increasing trend as they replace Ozone Depleting Substances (ODS) being phased out under the 1987 Montreal Protocol. Per capita GHG emissions in California have dropped from a 2001 peak of 14.0 tons per person to 10.7 tons per person in 2018, a 24% decrease.

For heavy-duty vehicles, the State SIP Strategy calls for combustion engine technology that is effectively 90% cleaner than today’s standards. Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions. emissions by more than 20%.

HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. 10 ) of urban air, a fraction known to be enriched with non-tailpipe constituents.

Study estimates ~4M children worldwide develop asthma each year because of NO2 air pollution

Green Car Congress

Improving access to cleaner forms of transportation, like electrified public transport and active commuting by cycling and walking, would not only bring down NO 2 levels, but would also reduce asthma, enhance physical fitness, and cut greenhouse gas emissions. Achakulwisut et al.

UC Berkeley study confirms that yes, EVs do what they promise to do

Baua Electric

A new study from UC Berkeley confirms what EV fans already know: EV adoption does, in fact, make the air cleaner. Researchers were able to track that data via a network of sensors around the Bay Area that monitor both CO2 and five critical air pollutants: carbon monoxide, nitrous oxides (NO and NO 2 ), ozone, and particulates (PM 2.5).
