The international shipping agency already has the legal authority to implement and enforce policies to achieve its new climate target, according to new analysis published by Environmental Defense Fund and Columbia Law School’s Sabin Center for Climate Change Law. “The Legal Bases for IMO Climate Measures” finds the International Maritime Organization (IMO) can – by simply amending its existing regulations – ensure speedy entry into force of climate measures, while ensuring the measures are legally binding, enforceable and implemented globally. Countries at the IMO agreed in April to reduce international shipping’s greenhouse gas pollution by at least 50% by 2050 compared to 2008 levels, and to peak emissions as soon as possible.
