Japan is trying to strengthen its presence in the international maritime sector and has set a target of net-zero greenhouse gas emissions by 2050 as a goal for the shipping industry. The country is also encouraging its domestic shipbuilding industry to take the initiative to supply greener vessels. Japan's Ministry Of Land, Infrastructure, Transport and tourism last month launched the enhanced marine emissions target to achieve net-zero GHG emissions from ocean-going vessels by 2050, jointly with the US, the UK, Norway and Costa Rica at the International Maritime Organisation's Marine Environment Protection Committee meeting, ahead of any other countries. Marine Environment Protection Committee has recognised that it needs to strengthen its GHG emissions targets to net-zero by 2050 and Ministry Of Land, Infrastructure & Transport is considering taking the lead to set up a concrete plan to achieve this, with an appropriate carbon pricing and carbon levy scheme. The IMO currently requires that vessels reduce GHG emissions by 50pc and CO2 emissions by 70pc by 2050 compared with 2008 levels. Ministry Of Land, Infrastructure, Transport strongly anticipates that this net-zero emissions target will encourage the Japanese shipping industry to take the initiative in building vessels that can run on alternative marine fuels, such as ammonia and hydrogen. Japan's major shipowners NYK Line, Mitsui OSK Lines and K Line have all set a target to achieve net-zero GHG emissions by 2050. This is also expected to prompt domestic shipbuilders to launch greener vessels. Japan has been developing ammonia/hydrogen-powered marine engines, starting with tugboats and ferries, and the technology for large coastal and ocean-going ships is expected to be developed by 2025.
