Today we are introducing a roadmap that presents an opportunity for the UK to set the standard for excellence globally when it comes to establishing equitable, transparent, high-integrity and standardised markets for marine natural capital. It builds on the significant actions already underway across all the nations of the UK to protect, restore and sustainably manage marine and coastal ecosystems. Devolution means that market development should be tailored to the four nations of the UK. However, through meaningful collaboration, we can achieve shared but nationally appropriate approaches that uphold the highest standards of integrity to deliver scale and real impact. Developed in collaboration with leaders spanning academia, industry, finance, government and not-for-profits across the nations, this roadmap is a milestone for bringing actors together to take urgent action for recovery of the marine environment. It presents a pathway towards valuing ecosystem services appropriately by progressing an enabling policy environment that can bring financial resources to bear, together.
