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

Green Car Congress

The study was published in the journal Atmospheric Environment. Both radiative forcing (RF) and effective radiative forcing (ERF) terms and their sums are calculated for the years 2000–2018. Aviation accounts for 3.5% This new study is based on a thorough review of a decade of research on aviation emissions. Pitari, M.J. Prather, R.

Study finds that replacement programs that reduce vehicle lifetime can result in increased lifecycle CO2 emissions

Green Car Congress

Effects of changes in the average lifespan of ordinary passenger cars newly registered between 1990-2000 on total induced CO 2 emissions in 2000. If the 2000 market shares of hybrid cars were 14.1%, a one-year decrease in lifetime will reduce life-cycle CO 2 emission in 2000 by 0.6%. Credit: ACS, Kagawa et al. Technol. ,

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

Green Car Congress

Maritime CO 2 emissions are estimated at more than 1000 million tonnes per year, or 3% of total emissions, and are expected to reach 2000 to 3000m tonnes by 2050. Costas Pantelides, Managing Director of PSE.

of CO 2 per km from 2016, according to final data published by the European Environment Agency (EEA). The demand for passenger cars has been the main contributing factor to the trend in CO 2 emissions since 2000: when demand decreases, the emissions follow. This increase brings car manufacturers further away from their 2021 targets.

They recycled the catalyst over five runs without significant loss of activity (turnover number > 2000). Despite its outsized impact on the environment, the actual concentration of CO 2 in the atmosphere is relatively small—400 parts per million is 0.04% of the total volume. —G.K. Surya Prakash.

New cars in Europe in 2013 collectively met 2015 CO2 target two years ahead of the deadline

Green Car Congress

Cars sold in Europe in 2013 were collectively 4% more efficient than the year before, according to provisional data from the European Environment Agency (EEA). Compared to the current levels the average emissions gap between gasoline and diesel was more than 10 times higher in 2000. Source: EEA. Click to enlarge. There were 11.8

Average CO2 emissions from new cars in the EU dropped by 3.7% last year

Green Car Congress

The European Environment Agency today published provisional data on average CO 2 emissions from new passenger cars sold in the EU in 2010, showing a 3.7% This is the second largest annual decline since the monitoring scheme began in 2000. drop compared to last year. This report shows that cars are getting heavier again.
