Following the climate change summit in Paris, the International Monetary Fund suggested implementing a carbon tax of $30 per tonne of CO₂ emitted from maritime and aviation fuels, which it says could raise around $25bn a year. The International Chamber of Shipping strongly opposes this measure, stating a preference for a fuel levy instead

It is not the first time the ICS has stood up against carbon tax. In October 2015, the ICS rejected a call from OECD think tank the International Transport Forum to impose a $25 levy on carbon.
