From cutting global CO2 that shipping drives, to tackling soaring NOx, SOx, and PM2.5 emissions, tightening sulphur and efficiency rules, and rolling out EU ETS and MRV coverage, the marine industry is racing toward decarbonisation at the same time global trade volume and fleet size keep expanding.

Key Takeaways

  • Global shipping (international) greenhouse gas emissions were about 1,076 million tonnes CO2 (2018), 2.89% of global CO2 emissions
  • Shipping emissions were projected to rise by 50% to 250% by 2050 compared with 2008 levels depending on scenario
  • IMO agreed to reduce total annual GHG emissions by at least 50% by 2050 compared with 2008
  • The global merchant fleet (vessels above 100 gross tons) reached 105,000 ships in 2023
  • UNCTAD reported global merchant fleet size of 2.1 billion deadweight tonnes (dwt) in 2023
  • UNCTAD reported average ship age increased to 11.4 years in 2023

Shipping emissions dominate change: caps, ETS, NOx SOx, and ballast rules reshape marine.

Emissions & Environment Interpretation

Global shipping is responsible for roughly 2 to 3% of the world’s greenhouse gases, and while the industry and regulators have agreed to cut emissions and carbon intensity sharply, the long and messy road to decarbonization now runs straight through tighter sulfur limits, demanding reporting rules, and even ballast water treatment designed to keep more than just pollution from traveling with the ships.

Trade, Fleet & Traffic Interpretation

In 2023 the world kept trading by sea at full scale, squeezing ever more capacity out of a fleet of 105,000 ships that is aging to 11.4 years, with 11.5 billion tonnes moved, major canals under pressure, ports managing around 14 million calls, container rates hovering near breakeven to profitable depending on the index, and just a handful of liner giants controlling most capacity, while tankers and offshore activity quietly flexed to carry everything from dry bulk to oil and gas and even help power rising US crude exports.
