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.

Changes in emissions by Scoping Plan sector between 2000 and 2017. Emissions are organized by the categories in the AB 32 Scoping Plan. Biofuels such as ethanol, biodiesel, and renewable diesel can displace fossil fuels and reduce the amount of fossil-based CO 2 emissions released into the atmosphere. Source: ARB.

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? Research takes a long time.

To put this into perspective, this means that air pollution causes more extra deaths a year than tobacco smoking, which the World Health Organization estimates was responsible for an extra 7.2 The researchers found that air pollution caused an estimated 8.8 million extra deaths globally rather than the previously estimated 4.5

California ARB moves forward with climate and air quality actions

Green Car Congress

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. Reducing these pollutants can have a more immediate beneficial impact on climate change, and reduces harmful toxins, such as cancer-causing particulates, in California communities.

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

SLCPs may account for an estimated 40% of global warming, increasing the impacts of climate change. In this SLCP Strategy, we outline SLCP emission reduction actions that provide a wide array of climate, health, and economic benefits throughout the State.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Soot could be further reduced by converting vehicles to run on renewable electric power. 1990; Anisimov, 2007] and chemical production of ozone in already-polluted locations [Jacobson, 2008b]. These three gases are all greenhouse gases, and ozone is a surface air pollutant. Tags: Climate Change Emissions.
