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. Aviation accounts for 3.5% —Marianne Tronstad Lund, co-author.

IEA: CO2 emissions from fuel combustion rose 2.2% in 2013, below the average rate since 2000

Green Car Congress

According to the latest data released by the International Energy Agency (IEA), CO 2 emissions related to the energy sector, which is the source of nearly two-thirds of human-generated greenhouse gases, rose 2.2% Both years were below the average growth rate since 2000 of 2.5%. In absolute terms, global CO 2 emissions increased by 0.7

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

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.

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Source: Bond et al.
