Shipping firms vow to cut emissions if governments support low-carbon tech

Industry calls for levy to fund new technologies - but environmentalists say proposal blocks climate progress

The global shipping industry has pledged to reduce greenhouse gas emissions to zero by mid-century - but only if governments impose a mandatory levy on shipping fuel to fund the development of new low-carbon technology.

The International Chamber of Shipping (ICS), which represents the majority of the global shipping industry, submitted the plans to the International Maritime Organization (IMO), the worldwide regulator and part of the UN.
