As seen on the Ellen MacArthur Foundation website – ZEMBA: A buyers alliance to unlock zero-emission shipping

In August 2025, the Ellen Macarthur Foundation (EMF) published a case study focused on ZEMBA, featuring an interview with ZEMBA’s President and CEO Ingrid Irigoyen.

EMF’s case study focused on ZEMBA’s history and approach as part of EMF’s overarching work, highlighting commercially driven collaboration. 

Read an excerpt from the article below:

“Before 2023, companies looking to decarbonise their supply chains had no viable access to zero-emission shipping solutions. High costs and uncertain demand gave carriers little incentive to invest in zero-emission fuels, barring individual businesses from shifting the market. The Zero Emission Maritime Buyers Alliance (ZEMBA) emerged as a collective procurement initiative to aggregate demand and send a clear signal to shipping providers and policymakers for new shipping solutions.”
