UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

The climate change benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Global benefits from full implementation of the identified measures in 2030 compared to the reference scenario.

Study Concludes Warming Climate Will Increase Ozone Levels in Major California Air Basins; Climate Change and Regional Air Quality Are Intertwined Problems

Green Car Congress

Illustration of projected ozone changes in the South Coast region due to climate change in 2050. Areas in orange and red could see ozone concentrations elevated by 9 to 18 parts per billion. We already know that climate change will bring us increased forest fires, shorter winters, hotter summers and impact our water supply.

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.

UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). The contribution of HFCs to climate forcing is currently less than 1% of all greenhouse gases.

Study: surface ozone in India in 2005 damaged 6M tonnes of crops, enough to feed 94M people in poverty

Green Car Congress

Ozone, the main component of smog, is a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. New research shows that ozone pollution damaged millions of tons of wheat, rice, soybean and cotton crops in India in 2005. Surface ozone pollution in India damaged 6 million metric tons (6.7

Fast action on black carbon, ozone and methane could help limit global temperature rise to 2 degrees C

Green Car Congress

The climate change benefit is estimated for a given year (2050) and human health and crop benefits are. Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and

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

Green Car Congress

The data shows a slight increase in overall emissions from the previous year, and a slight decline in emissions from transportation, which is the state’s main source of both GHGs and air pollutants. Transportation emissions declined 1.5 Source: California Air Resources Board (ARB). Total statewide 2018 GHG emissions were 425.3
