Study estimates global black carbon emissions up 72% from 1960-2007; BC emissions intensity down 52%

Green Car Congress

A study led by a team from Peking University has estimated that global black carbon (BC) emissions increased from 5.3 teragrams per year in 2007 (+72%). The Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) said BC has a direct radiative forcing of +0.4 (+0.05 Credit: ACS, Wang et al.

New inventory of black carbon emissions from China finds 2007 levels higher than previously reported

Green Car Congress

for year 2007. A new black carbon (BC) emissions inventory from China found BC emissions levels in 2007 of 1,957 Gg BC—higher than reported in earlier studies. Black carbon is released into the atmosphere via incomplete combustion of carbonaceous fuel and is of major concern because of the impact on climate systems.

Study projects net cooling of climate from ship emissions through 2050

Green Car Congress

Shipping-induced global temperature change in 2050 using different parameterizations of Indirect Aerosol Effect (IAE). 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?
