Introduction According to the International Maritime Organization (IMO), the shipping industry currently accounts for 2.2% of global emission of greenhouse gases (GHG), with the potential, if left unregulated, to increase 50-250% by 2050. In response, the IMO has targeted a 50% reduction in GHG emissions by 2050 via its GHG Strategy, approved in April 2018. Against this background, the Poseidon Principles for Marine Insurance (PPMI) came into force on December 15, 2021.
