Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

New research from Chalmers University of Technology, Sweden, finds that the discharge water from ships’ exhaust gas treatment systems—i.e., For many years, we’ve flagged the fact that scrubbers account for disproportionately large emissions of hazardous and acidifying substances into the marine environment.

Chalmers study: ban on sales of fossil-fuel cars greatly reduces lifecycle GHG mainly due to tailpipe emissions; risk of carbon leakage in manufacturing

Green Car Congress

If a ban were introduced on the sale of new gasoline and diesel cars, and they were replaced by electric cars, the result would be a significant reduction in lifecycle carbon dioxide emissions primarily due to reduced tailpipe CO 2 emissions, according to a new lifecycle study by researchers at Chalmers University of Technology, Sweden.

Scania, Lund, Chalmers and KTH Collaborating in Research on More Efficient, Lower-Emitting Heavy-Duty Engine Fueled by Biofuels

Green Car Congress

Scania will focus on developing an engine that can operate on both alcohol- and gaseous methane-based fuels that will combine the higher efficiency of diesel (compression ignition) technology with the exhaust aftertreatment systems of Otto (spark ignition) technology. Initially set to run from 2009-2012 with no definite ending year.
