This standard will provide detailed methodology requirements for carbon services delivered from nature projects in UK markets. It will address an urgent and priority need to drive consistency and quality across the range of carbon schemes in operation (research identified 48+ schemes in the UK). The standard will be applicable across all habitats and split across three parts (land, marine and soils). The standard will build on the IPNIS and align where possible with international voluntary carbon market standards. It will work with, and be applicable to, schemes issuing carbon units in UK markets.
