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. Both radiative forcing (RF) and effective radiative forcing (ERF) terms and their sums are calculated for the years 2000–2018. 2 ), and NO x (17.5?mW?m Pitari, M.J. Prather, R. Sausen, L.J.

UK new car CO2 emissions fell 3.5% in 2010 and more than 20% since 2000

Green Car Congress

Average CO 2 emissions from new cars have fallen by more than 20% since 2000. Cars in the sub-130 g/km CO 2 category represented almost 40% of the market in 2010 compared with less than 1% in 2000. Executive (-28.1%) and Mini (-25.8%) segments recorded the biggest improvements against the levels of 2000. .

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

Green Car Congress

Both years were below the average growth rate since 2000 of 2.5%. 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% in 2013 to total 32.2 gigatonnes, compared with the 0.6%

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,

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

Green Car Congress

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. The 28% decrease in gasoline prices (in nominal dollars) from 2014 to 2015, along with the continued economic recovery, led to higher fuel consumption.

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

Because diesel cars typically consume less fuel than gasoline equivalents they emit, on average, 15-20% less CO 2. These ongoing improvements mean average CO 2 is still a third (-33.1%) lower than in 2000. Alternatively fueled vehicles (AFV) registrations rose by 34.8% However, this increase was not enough to offset a -17.1%
