CIMAC, the global association of the Internal Combustion Engines Industry, has just published two new CIMAC White Papers titled “White Paper 3: Efficiencies and Maturities of (Net) Zero Carbon Fuel Pathways” and “White Paper 4: Importance of a Well-to-Wake Approach”.

CIMAC reiterates the need for (net) zero or zero carbon fuels as necessary steps to achieve the required GHG emission reductions in maritime shipping. While the two white papers and the CIMAC position published earlier outline the bigger picture of the current alternative fuels debate in maritime shipping, White Paper 3 now supports the previous White Papers by giving an overview of current and projected maturities and energy efficiencies of the discussed technologies and fuel pathways. Subsequently, the White Paper 4 builds on White Paper 3 and asserts why a well-to-wake perspective is essential when assessing alternative fuels and the respective policies in maritime shipping.

Both white papers are issued by the Greenhouse Gas strategy group and are available on the CIMAC website at:
