But some countries are more on board than others.
International shipping is a big contributor to climate change, and it doesn’t change quickly, but its companies are starting to invest in cleaner fuels.
Growing ship numbers and reductions in the industry’s total emissions add up to big emission cuts per ship – as much as 60% by 2030 and 91% by 2040. The days of fossil-fuelled ships are now numbered.
Shipping companies have billions invested in fleets that were built to last decades. Now, the US is calling for zero emissions by 2050, and the EU is raising the cost of fossil fuel use.
If shipping were a country, it would rank between Japan and Germany as the sixth-largest contributor to global carbon dioxide emissions.
Shipping companies are expected to halve their greenhouse gas emissions by 2050.
