The Port of Los Angeles (LA) has agreed to work with the Port of Shanghai to form a transpacific green shipping corridor as part of an effort to reduce emissions from one of the busiest cargo routes.

Convened by the two ports and C40 Cities, the partnership will seek to develop a plan by the end of the year.

The ‘Green Shipping Corridor Implementation Plan’ will include deliverables, milestones and specific roles in the partnership.

Several other maritime stakeholders, including shipping companies and a network of cargo owners, are also part of the initiative.

The collaboration seeks to transition gradually to low, ultra-low and zero-carbon fuelled ships within this decade.

It also seeks to develop ideal management practices that will help in improving efficiency for all ships using the corridor, as well as assist in reducing emissions.

LA and Shanghai also aim to concurrently reduce supply chain emissions from their port operations.

Port of LA executive director Gene Seroka said: “International collaboration is essential to decarbonise global supply chains. We look forward to partnering with the Shanghai Municipal Transportation Commission, the Shanghai International Port Group, leading shipping lines and major cargo owners to reduce greenhouse gas emissions in the maritime supply chain. It’s time to get started on this important work.”

C40 Cities executive director Mark Watts said: “Accelerating efforts to decarbonise the shipping sector is urgent if we are to limit global heating to 1.5°C.

“By convening international coalitions of the willing and creating a scalable and replicable model for other cities to follow, we hope this ground-breaking green shipping corridor initiative will catalyse action on a global scale.”

C40 is a network of cities across the world that are collaborating to combat climate change.
