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.

Study finds reduction of low-frequency noise from transition to electric buses improved residents’ health

Green Car Congress

The health of residents living alongside a bus route in Gothenburg, Sweden, improved when hybrid buses were replaced by buses fully powered by electricity. Accompanying the lower noise levels from bus traffic was a reduction of fatigue, day time sleepiness and low mood, a study at the University of Gothenburg shows.

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.
