Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. This new study is based on a thorough review of a decade of research on aviation emissions. The formation and emission of sulfate aerosol yields a negative (cooling) term.

Roskill expects only 3.2% reduction in shipping emissions of spodumene concentrate by 2030; order of magnitude below IMO ambition

Green Car Congress

Shipping emissions form a significant part of the commodity supply chain’s carbon footprint, particularly for those commodities reliant on the mass transport of low-grade ores and concentrates. Roskill has analyzed the trend in carbon intensity of shipping using spodumene concentrate as an example. Background Data.

EIA releases report on CO2 emissions by state; California led in 2010 with transportation-sector emissions

Green Car Congress

Energy-related CO 2 emissions buy state, 2010. The US Energy Information Administration (EIA) has released a new report, State-Level Energy-Related Carbon Dioxide Emissions, 2000-2010. The report shows a significant variation of energy-related carbon dioxide emissions across states on both an absolute and a per capita basis.
