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.

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.

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.

MIT study finds including non-CO2 emissions from synthetic aviation fuel in lifecycle analysis of climate impact can lead to decrease in relative environmental merit; need for a holistic analysis framework

Green Car Congress

However, this approach neglects non-CO 2 combustion emissions and effects, namely, soot and sulfate aerosols, water vapor, and NO x. In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming. —Stratton et al.

EPA says methane emissions from natural gas production have dropped 36% from 2007-2011

Green Car Congress

(The figure includes the direct effects and those indirect effects due to the production of tropospheric ozone and stratospheric water vapor.) In 2011, CH4 emissions from coal mining were 63.2 From 1990 to 2011, CH4 emissions from landfills decreased by 44.7 30.3%), with small increases occurring in some interim years.
