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

Green Car Congress

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 ventilation air from coal mines. Replacing coal by coal briquettes in cooking and heating stoves.

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

Green Car Congress

Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said. Click to enlarge. °C (within a likely range of 0.2-0.7

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.

coal, oil, natural gas, and biomass). Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. Summer fine particulate matter (PM 2.5 ) increases on average and largest in areas with increased coal-fired power generation demands. Seasons and times of day.

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The burning of coal releases more carbon dioxide than other fossil fuels, as well as comparatively high levels of other pollutants, including sulfur dioxide, nitrogen oxides, and particles such as ash.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C All 14 would curb the release of either black carbon or methane.
