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

Green Car Congress

These contributions involve a large number of chemical, microphysical, transport and, radiative processes in the global atmosphere. Seen together, the climate impact of these two factors is bigger than that of the sector’s carbon emissions. Net warming from contrail cirrus is a sum over the day/night cycle. Pitari, M.J. Prather, R.

EIA: US energy-related CO2 dropped 2.7% in 2015; of end-use sectors, only transportation increased

Green Car Congress

These factors included a decline in the carbon intensity of the energy supply (CO 2 /British thermal units [Btu]) of 1.8%; and a 3.4% Of the four end-use sectors, only transportation emissions increased in 2015 (+2.1%). —“US Energy-Related Carbon Dioxide Emissions, 2015”. decline in energy intensity (Btu/GDP).

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

Green Car Congress

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. Source: EIA. Click to enlarge. tonnes/person).

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

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.

Ford researchers: global light-duty CO2 regulatory targets broadly consistent with 450 ppm stabilization

Green Car Congress

The SMP model calculates 2000?2050 2050 well-to-wheels (WTW) transportation sector CO 2 emissions in 11 world regions for a number of vehicle types. They converted from an absolute amount to scale relative to 2000. To achieve 450 ppm, WTW LDV CO 2 emissions decrease 25% from 2000 and 34% between 2010 and 2050.

DNV and PSE develop concept for on-ship chemical CO2 capture; capable of reducing ship CO2 emissions by up to 65%

Green Car Congress

The results from the Maritime CCS (carbon capture and storage) research and development project show that the concept is technically feasible and capable of reducing ship CO 2 emissions by up to 65%. Det Norske Veritas (DNV), a leading classification society, and Process Systems Enterprise Ltd.

EIA: US energy-related CO2 emissions down 2.4% in 2011 while GDP rose

Green Car Congress

The US Energy Information Administration (EIA) reported that after an increase in 2010 of 3.3%, energy-related carbon dioxide emissions in the US in 2011 decreased by 2.4% (136 million metric tons), while GDP grew by 1.8%. This indicates that the carbon intensity of the economy declined by about 4.2%.
