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.

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.

Radiative forcing due to perpetual constant year 2000 emissions grouped by sector for 2020 (left) and 2100 (right) showing the contribution from each species. At the same time, one type of aerosol called black carbon, or soot, actually absorbs incoming solar radiation, heats the atmosphere, and drives the evaporation of low-level clouds.

Clean clouds and non-light-absorbing (transparent) particles scatter or reflect sunlight, reducing the amount of solar energy that is absorbed by the surface. BC suspended in the atmosphere absorbs some incoming solar radiation, heating the atmosphere. Most solar radiation is absorbed by the Earth’s surface and warms it.

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. World ethanol production for transport fuel tripled between 2000 and 2007 from 17 billion to more than 52 billion liters (13.7 Source: “Assessing Biofuels”.

Highly Ranked catachip @ Apr 19th 2009 4:57PM @ Elodie As long as the electricity is generated from wind, hydro, solar, or nuclear then there are zero emissions. Neutral who? @
