Helena Delgado Nordmann, UK retailer Tesco's sustainable aquaculture and fisheries manager, has left the supermarket chain to join global non-profit CDP as associate director.

Nordmann joined Tesco in 2018.

She was part of a team that adopted a new approach, working in partnership with the supermarket retailer's store-brand suppliers to introduce new due diligence processes within its tuna supply chain, with the the goal of 100 percent Marine Stewardship Council (MSC) certification across its tuna ranges by 2025.

"I can only highly recommend this job," she said in response to an advertisement for her replacement posted on Linkedin.
