Leading shipping players have voiced concern over leaked European Union plans to make shipowners — not charterers — pay for carbon under its Emissions Trading System (ETS).

Industry figures claimed this week that the proposal, reported by TradeWinds and due to be confirmed on 14 July, would divide responsibility for paying for fuel from meeting the cost of carbon allowances, and undermine the aim of cutting emissions.

Others sounded the alarm on the use of revenues garnered from the scheme and called for decisive action from the International Maritime Organization to enact a global mandatory market-based measure (MBM).
