Study projects net cooling of climate from ship emissions through 2050

Green Car Congress

A recent study by an international team calculated that shipping causes a net cooling of climate across all parametrizations of the indirect aerosol effect (IAE) and scenarios throughout the period 1900?2050. A recent study commissioned by the International Maritime Organization (IMO) estimated total emissions of 1046 Tg CO 2 yr ?1

Bromine also can remove ozone from the lowest layer of the atmosphere, the troposphere. Despite ozone’s beneficial role blocking harmful radiation in the stratosphere, ground-level ozone is a harmful pollutant. Bromine then reacts with a gaseous form of mercury, turning it into a pollutant that falls to Earth’s surface.

Volkswagen to use CO2 as refrigerant for future air conditioning systems

Green Car Congress

While last year it appeared that the auto industry as a whole would shift to R-1234yf, in September 2012, Daimler said that internal testing had identified safety (flammability) issues under certain conditions, and that it would not use R-1234yf in its products. The current work following Daimler’s balk in September 2012 is the fourth.
