## Summary

Dr. Lynn Loo, CEO of the Global Centre for Maritime Decarbonisation (GCMD), explains why decarbonizing shipping requires a diverse portfolio of fuels rather than a single solution like sustainable aviation fuel. She details the operational challenges of low-volumetric-energy-density fuels like methanol and ammonia, the regulatory pressure from the IMO’s revised greenhouse gas strategy, and the potential role of onboard carbon capture as an interim measure.
