Renewable fuels should contribute at least 70% of the sector’s energy mix in 2050, IRENA’s “A pathway to decarbonise the shipping sector by 2050“ shows, outlining a roadmap for the global shipping sector in line with the global 1.5°C climate goal.
If the international shipping sector were a country, it would be the sixth- or seventh-largest CO2 emitter. IRENA’s decarbonisation 1.5°C pathway is based on four key measures such indirect electrification by employing green hydrogen-based fuels, the inclusion of advanced biofuels, the improvement of vessels’ energy efficiency and the reduction of sectoral activity due systemic changes in global trade dynamics.
