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

Green Car Congress

While coal use causes warming through emission of heat-trapping carbon dioxide, it also releases comparatively large amounts of sulfates and other particles that, although detrimental to the environment, cool the planet by blocking incoming sunlight. —Tom Wigley. Methane is an especially potent greenhouse gas. degree Celsius).

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.

Researchers Discover New Chemistry for Ozone Formation; Not Yet Monitored or Incorporated into Atmospheric Models

Green Car Congress

A) shows the base case peak concentrations for O 3 (ozone), ClNO and HCl in parts-per-billion by volume (ppbv). (B) Under extreme circumstances, this previously unknown chemistry could account for up to 40 parts per billion (ppb) of ozone; the current US Environmental Protection Agency (EPA) 8-hour average standard is 75 ppb.

CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. Hydrogen is not a greenhouse gas, but its chemical reactions in the atmosphere affect greenhouse gases such as methane, ozone, and stratospheric water vapor. Sand et al.

Japan Researchers Use Liquefied DME to Extract Oil from Algae at Room Temperature at High Yield

Green Car Congress

Unlike other ethers, DME does not form peroxides, is non-toxic, has no effect on global warming nor ozone depletion and can be considered an environmentally friendly solvent. Both DME synthesized gas and liquid from coal are being utilized more frequently as inexpensive fuels in the People’s Republic of China.

EPA Proposes Transport Rule to Cut Pollution from Power Plants in 31 States and DC; New Approach for Pollution Reduction

Green Car Congress

This proposal reduces emissions contributing to fine particle (PM 2.5 ) and ozone nonattainment that often travel across state lines. SO 2 and NO x react in the atmosphere to form fine particle pollution and ground-level ozone (smog), which are linked to widespread illnesses and premature deaths. NO x emissions would drop by 52%.
