Attaching giant sails to cargo ships could slash their greenhouse gas emissions

Fitting giant sails to cargo ships could reduce their greenhouse gas emissions by at least 30 per cent, research shows.

Reducing speeds to use less fuel when the engines are running would cut emissions by a further 10 per cent, according to the Institution of Mechanical Engineers.

The government should part-fund a demonstration ship using retrofitted sails as part of the UN Cop26 climate change conference in Glasgow in November to improve understanding of the potential of wind power, the institution said.

The government announced this week that emissions from international shipping would be included in the UK’s climate change targets.

However, the institution’s report said rapid action was needed to clean up shipping because of slow progress on the issue.
