Cargo ships move more than 80% of the world’s internationally traded goods, making them essential to the global economy, but they’ve traditionally been fueled by heavy fuel oil or marine gasoil, both of which are emissions-intensive. With 60,000 or so ships in service, they account for an estimated 2.8% of global greenhouse gas (GHG) emissions, a percentage the International Maritime Organization (IMO) would like to reduce. At the 80th session of the IMO’s Maritime Environment Protection Committee (MEPC) in July, the group adopted a provisional agreement to eliminate GHG emissions from shipping by a date as close to 2050 as possible, with intermediate goals for emissions reduction by 2030 and 2040. Clearly, radical innovations will be required to meet the IMO’s goals. In today’s RBN blog, we look at some of the initiatives directed at emissions reduction in shipping and the challenges to (and opportunities for) operational improvements, especially regarding LNG carriers.
