In April 2018, the shipping industry pledged to a wide GHG target of reducing emissions by ‘at least’ 50% by 2050. Achieving this target will require a combination of short, mid and long-term policy measures.


The infographics highlight the huge possibility of untapped renewable energy potential to produce low- or zero-emissions electro-fuels and what next steps are necessary to scale up these solutions. The infographics are based on findings from about 10 years of research, like Low Carbon Shipping & Shipping in Changing Climates projects and collaboration with Lloyd’s Register on Zero Emission Vessels.

Renewable sources

  • Electro-fuels: Production of gaseous/liquid zero-carbon electro-fuels from sustainable sources;
  • Electrification: Production of electricity from renewable energy resources in combination with battery storage technology.


  • 1st Generation: Produced from food resources, such as wheat and meat;
  • 2nd Generation: Produced from bio-mass resources such as wood and organic waste;
  • 3rd Generation: Produced from sustainably cultivated organic materials, such as algae;
  • 4th Generation: Produced from bio-mass resources in combination with carbon dioxide capture and storage.

However, the infographics note that there is no one-size-fits-all solution. They explain that different solutions fir different ships, according to size, power and vessel requirements.
