Ensuring the future of responsible
marine insurance
The Poseidon Principles for Marine Insurance create a common global baseline that is consistent with and supportive of society’s goals to better enable insurers to assess and disclose their portfolio alignment.
The Poseidon Principles for Marine Insurance recognize the role insurers play in the shipping industry and promote responsible environmental stewardship throughout the maritime value chain. They set a benchmark for what it means to be a responsible insurer in the maritime sector and provide actionable guidance on how to achieve this.
As a result, the Poseidon Principles for Marine Insurance enable insurers to assess and disclose their portfolios with responsible environmental impacts and incentivize international shipping’s decarbonization – to support a better future for the shipping industry and society.
The Poseidon Principles for Marine Insurance are applicable to insurance providers with hull and machinery coverage and are supported by insurance brokers and business partners. They apply globally, to all shipping activities where a vessel or vessels fall under the purview of the IMO.










As risk managers, insurers and investors, the insurance industry has a key role in supporting the transition to a net-zero economy. The Poseidon Principles will serve our institutions as well as our clients to quantitatively assess and disclose the climate alignment of their underwriting portfolios and thus improve decision-making at a strategic level and shape a sustainable future for all.
