Study from Thuringia shows 50% of harmful soot comes from local sources, 50% from long-distance transport

Green Car Congress

Soot particles from oil and wood heating systems as well as road traffic can pollute the air in Europe on a much larger scale than previously assumed. This is what researchers from the Leibniz Institute for Tropospheric Research (TROPOS) conclude from a measurement campaign in the Thuringian Forest in Germany.

Toshiba’s SCiB Li-ion battery system Japan’s first recognized compliant with ClassNK guidline for marine vessels

Green Car Congress

At a time when pollution regulations are increasingly focused on the emissions ships generate, the SCiB will contribute to the protection of the marine and global environments. Ships are responsible for about 800 million metric tons of CO 2 every year, roughly equivalent to the annual emission of Germany.

ITF study finds limited environmental and safety impacts of car fleet renewal schemes in US, France and Germany

Green Car Congress

Car fleet renewal schemes introduced in the US, France and Germany to stimulate consumer spending on cars in the wake of the 2008. While scrappage schemes have the potential to deliver on objectives such as reducing pollutant emissions, these have not done so as well. imperfectly aligned with fuel consumption or pollutant emissions.
