Ships can trigger large methane emissions just by moving in ports
- Methane emissions measured in shipping lane 20 times higher than in undisturbed area, study finds
- Shipping’s contribution to global warming could be far bigger than previously thought
Ships in shallow waters, including nine of world’s 10 biggest ports, can churn up bubbles of planet-warming methane from the seabed to the surface, according to a study by Chalmers University in Gothenburg. These emissions may be a big and so far unknown source of shipping’s climate impact
