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

Green Car Congress

In addition to CO 2 , air traffic causes condensation trails and nitrogen oxide (NO x ) emissions from the combustion of the airplane’s fuel. Seen together, the climate impact of these two factors is bigger than that of the sector’s carbon emissions. The formation and emission of sulfate aerosol yields a negative (cooling) term.

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

Further, the study compares 450 ppm LDV CO 2 glide paths derived using only vehicle efficiency improvements against those derived using both vehicle and fuel actions. The SMP model calculates 2000?2050 They converted from an absolute amount to scale relative to 2000. Because of the high LDV emissions in 2000?2010,

UK auto industry warns anti-diesel agenda and slow uptake of EVs could mean missing 2021 CO2 targets; rising CO2 average in 2017

Green Car Congress

The SMMT New Car CO 2 Report 2018: Driving the transition to a low carbon future showed that carbon tailpipe emissions rose last year for the first time in two decades by 0.8% Because diesel cars typically consume less fuel than gasoline equivalents they emit, on average, 15-20% less CO 2. less CO 2 than those they replaced.

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% The downward pressure on emissions was slightly offset by an uptick in transportation energy consumption that was influenced by lower fuel prices that put upward pressure on emissions. from 2014 levels.

GCP Carbon Budget Finds Anthropogenic CO2 Emissions Rose 2% in 2008 Despite Global Financial Crisis; Natural Sinks Not Keeping Pace With Increasing Emissions

Green Car Congress

Despite the economic effects of the global financial crisis (GFC), carbon dioxide emissions from human activities rose 2% in 2008 to an all-time high of 1.3 tonnes of carbon per capita per year, according to a new paper published by an international team of 31 scientists in Nature Geoscience. over the previous seven years.

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. million tonnes). million tonnes in Texas (8.3%).
