Nations considering global tax on shipping emissions

Nations are trying to reach an agreement to charge commercial vessels a fee for their emissions in what would effectively be the world’s first global carbon tax.

The International Maritime Organisation, which regulates international shipping, set a target for the sector to reach net-zero greenhouse gas emissions by about 2050, and committed to ensuring that fuels with zero or near-zero emissions are used more widely. Its Marine Environment Protection Committee meets Monday through Friday in London.

The committee, comprised of IMO member states, is working to approve proposed new global regulations to put a price on maritime greenhouse gas emissions and to set a marine fuel standard to phase in cleaner fuels. The measures are more than climate aspirations; they will become mandatory for ships operating globally, said IMO Secretary-General Arsenio Dominguez, who thinks the industry must do more to cut carbon pollution. The committee will “set the course for a net-zero future for the maritime sector,” he told The Associated Press(AP).

The future of clean shipping hangs in the balance, said Emma Fenton, senior director for climate diplomacy at a UK-based climate change nonprofit, Opportunity Green. Fenton said a high price, simple flat-rate levy on shipping’s greenhouse gas emissions is the only way to decarbonize the industry equitably.
