Yang Ming and PSA Push Beyond Ocean Shipping With Verifiable Sea and Land Carbon Insets

Yang Ming Marine Transport Corporation and PSA International have signed a memorandum of understanding to develop low carbon solutions that could help cargo owners reduce emissions across both maritime and landside transport operations.

The partnership combines Yang Ming’s cleaner shipping initiatives with PSA’s electrified terminals and integrated logistics network. The companies intend to create a joint carbon inset package covering sea and land transport, supported by emissions measurement, verification and digital tracking.

The agreement was signed by Ivan Chiang, Yang Ming’s Chief Logistics Officer and Senior Vice President, and Eddy Ng, PSA International’s Group Head of Operations, Technology and Sustainability.

The ceremony was witnessed by Kevin Lee, President of Yang Ming, and Ong Kim Pong, Group CEO of PSA International.

Shipping lines have traditionally concentrated decarbonisation efforts on vessels, fuel consumption and fleet efficiency. Cargo emissions, however, do not stop when a container reaches the quay.

The Yang Ming and PSA partnership is designed to address that wider journey by connecting ocean transport with terminal handling and landside logistics.

Yang Ming said its maritime fuel initiatives would be combined with PSA’s electrified terminal capabilities to provide customers with an adaptable and verifiable method of reducing transport related emissions.

“Enhancing green competitiveness is at the heart of Yang Ming’s operations,” Lee said. “As no single company can achieve supply chain decarbonisation alone, we are pleased to partner with PSA to provide a sea and land joint carbon inset package.”

Lee added that the collaboration would give customers a transparent approach to meeting sustainability objectives.

Yang Ming reported that it had reduced its carbon intensity by 63.32% at the end of 2025 compared with its 2008 baseline.

The Taiwanese carrier has also launched EcoSea+, a green transport service intended to help customers address Scope 3 emissions generated through transportation activities.

Scope 3 emissions often present the most difficult accounting challenge for cargo owners because they occur across suppliers, carriers, terminals and logistics providers. Measuring a container’s emissions across that chain can resemble assembling a puzzle when every participant holds only one piece.

Through the PSA partnership, Yang Ming plans to extend EcoSea+ beyond ocean navigation and into terminal and landside activities.

The collaboration will focus on a digital Book and Claim framework and a joint maritime and land based inset token package.

Book and Claim systems allow the environmental benefit from a lower carbon transport activity to be allocated to a customer even when the customer’s physical cargo cannot be directly moved using the lower emission option.

For cargo owners, the value of such a system depends heavily on credible data, clear allocation rules and independent verification. Yang Ming and PSA said the proposed framework would provide a transparent and accountable pathway for customers pursuing supply chain decarbonisation targets.

The partners will work on emissions measurement and verification alongside the digital framework.

PSA is advancing its Node to Network strategy by connecting port operations with broader supply chain services.

The company said its terminal and landside capabilities could support a greener logistics network and reduce emissions across end to end cargo movements.

“Tackling the challenges arising from climate change will require the collective efforts of all players in the maritime supply chain sector,” Ong said.

He added that PSA’s partnership with Yang Ming would support the transition towards a more sustainable global economy.

The agreement gives the two companies a structure for combining shipping, terminal and inland emissions initiatives into a single customer offering, with accountability built around digital records and verified carbon reductions.
