C40 Cities, a global network of mayors, along with the International Finance Corporation (IFC) and the International Association of Ports and Harbors (IAPH), has launched the Global Port Sustainability-Linked Loan (SLL) Initiative.

The initiative establishes the first global framework specifically tailored to deploy sustainability-linked loans for port decarbonisation projects worldwide. The partnership aims to deliver comprehensive market guidance, capacity-building programmes, and direct access to finance for port authorities, particularly in the global south where financing barriers have hindered green infrastructure deployment.

According to C40 Cities, ports require up to $2trn in cumulative investment through 2050 for shore power electrification, alternative fuel bunkering infrastructure, and zero-emission cargo-handling equipment. Yet approximately $200bn in sustainability-linked capital remains untapped due to technical, financial, and regulatory barriers facing port authorities.

The new initiative will aim  prepare more than 50 zero-emission port and shipping projects for investment by 2030, as well as mobilising maritime infrastructure finance for at least $1bn within three years

IAPH managing director Patrick Verhoeven commented, “The Global Port Sustainability-Linked Loan initiative marks an important step forward for further collaboration between ports, loan providers, and regulators. These land-based investments can fund long-term infrastructure and support offtake agreements for low and zero-carbon shipping fuels and liquid bulk transport.”
