Evaluation of the Responsible Sourcing Scheme for Growing Media - Report

Peat has long been a major ingredient in UK horticulture, but with its use declining and public interest in sustainable alternatives rising, there is increasing demand for clear, trustworthy information about growing media. A Responsible Sourcing Scheme (RSS) has been developed to help consumers understand the environmental impact of compost products through an A–E rating system. To support Scottish Government decision-making on future peat policy, a short review assessed the strengths and limitations of the RSS calculator. The review highlights where the tool can guide responsible sourcing and where refinements are needed, particularly around greenhouse gas emissions, supply-chain transparency and alignment with Scottish policy.
