Aligning ship insurance
with society’s goals

The Poseidon Principles for Marine Insurance are a global framework for assessing and disclosing the climate alignment of insurers’ hull and machinery portfolios. They enable the insurance sector to implement transparency and they establish a common, global baseline to quantitatively assess and disclose the climate alignment of the portfolios.

The Poseidon Principles for Marine Insurance are supported by a robust and industry-appropriate climate alignment assessment methodology and carefully considered accountability and enforcement requirements that support practical and robust data collection and analysis practices. The Poseidon Principles for Marine Insurance also establish transparency requirements for Signatories.

Principle 1: Assessment of climate alignment

Signatories will, on an annual basis, measure the carbon intensity and assess climate alignment (carbon intensity relative to established decarbonization pathways) of their hull and machinery portfolio using a robust industry-appropriate methodology established by the Poseidon Principles for Marine Insurance.
Affiliate members will support Signatories by sharing knowledge about the Assessment principle and climate alignment methodology with relevant stakeholders.
