The Department for Environment, Food & Rural Affairs (Defra) has published guidance on the British Standards Institution’s (BSI) Nature Investment Standards, which were developed with Defra funding and support from the devolved governments to provide a voluntary framework for the supply, storage and trade of nature credits in UK nature markets. The standards aim to ensure market integrity by preventing greenwashing, promoting transparency and consistency, and enabling private sector investment to deliver genuine environmental benefits, including biodiversity, carbon storage, clean air and water, and flood protection, while also encouraging community participation. The framework comprises a series of standards covering overarching principles, biodiversity, carbon, nutrient benefits, and community engagement, and is intended for use by credit suppliers, crediting programmes, market intermediaries, and buyers and investors across the UK.
