Global CO2 emissions stalled for the third year in a row

Green Car Congress

The annual assessment of global greenhouse gas (GHG) emissions by the JRC and the Netherlands Environmental Assessment Agency (PBL) confirms that CO 2 emissions have stalled for the third year in a row. Emissions from international transport (aviation and shipping) contribute another 3% to the total global GHG emissions.

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. Conversely, encouraging shortened vehicle lifetime via vehicle replacement schemes can result in higher total-induced greenhouse gas emissions, the authors found. Credit: ACS, Kagawa et al.

International automotive researchers emphasize the importance of continued development of the internal combustion engine

Green Car Congress

It is very likely that highly efficient “fully flexible” engines with hybridized solutions will be a big part of sought-after efficiency improvements, as well as emission/GHG reductions. mg/km of particulates), reaching values around 10 times the emission from the engine (5?mg/km). —Reitz et al. g/bhp-h or 15–20?mg/km).
