A statement from Rupert Howes, MSC Chief Executive

22 September 2025

"After almost two decades of negotiations, the ratification of the High Seas Treaty by 60 countries is a significant step forward to strengthen international protection of our ocean.  At the Treaty’s heart is the conservation and sustainable use of marine biological diversity – a goal which the MSC supports, and which is central to sustainable fishing.

"A healthy, thriving ocean is essential for wild fisheries and the communities that depend on them. As states and stakeholders prepare for the consider the Treaty’s implementation, it is vital that the role of sustainable fisheries management is recognised. MSC certified fisheries – including those catching commercially and ecologically iconic species such as tuna, toothfish and small pelagics on the high seas – demonstrate that it is possible for international fisheries to meet the highest bar for sustainability, provided effective international management, science and monitoring is in place.

"But faster progress is necessary. The ocean faces mounting pressure from climate change, overfishing and biodiversity loss coupled with increasing global demand for seafood.  We therefore urge nations and stakeholders to recognise the role of fishers alongside policy makers, businesses and NGOs in shaping the implementation of the treaty. Taking onboard these perspectives will be vital to ensuring the Treaty supports the food security and livelihoods of billions around the planet and conserves our incredible ocean."
