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.

Climate Expert: Don't Call It Geoengineering

Cars That Think

The leaders of the world have just returned from the UN's latest climate change summit, COP26 , in which the countries that have signed on to the Paris Agreement upped their commitments to fight climate change. Yet if countries continue on their present course, the world will likely have warmed by 2.7° In 2015, the U.S.

California ARB releases concept paper for public review on reducing short-lived climate pollutants

Green Car Congress

The California Air Resources Board (ARB) has released , for public review, a concept paper to initiate discussion on the development of a Short-Lived Climate Pollutant Reduction Strategy. Short-lived climate pollutants (SLCPs) include methane, tropospheric ozone, black carbon, and fluorinated gases.

Report argues advanced HD natural gas vehicles foundational for California to hit air and climate goals; near zero-emission potential

Green Car Congress

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. California’s Climate Protection Strategies do not help meet NAAQS Standards. Click to enlarge.

However, climate models to date have mischaracterized the effects of soot in the atmosphere, according to Jacobson, director of Stanford’s Atmosphere/Energy Program. Particle traps filter out soot particles from exhaust fumes. 1990; Anisimov, 2007] and chemical production of ozone in already-polluted locations [Jacobson, 2008b].

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

It is possible to use gasoline C made with hydrated ethanol (AEHC) with minimum risk of phase separation due to Brazilian climate conditions. 80.27, “high ozone season” means the period from June 1 to September 15 of any calendar year and “regulatory control period” means the period from May 1 to September 15 of any calendar year.
