Three more leading Japanese banks have signed up to the Poseidon Principles for sustainable ship finance.

MUFG Bank, Shinsei Bank and Sumitomo Mitsui Trust Bank have now joined the initiative.

The Poseidon Principles provides a framework for aligning ship finance portfolios with environmental targets.

The signatories commit to align their investment portfolios with the International Maritime Organization’s target to reduce annual greenhouse gas emissions by at least 50% by 2050.
