In the United Kingdom the Dairy Roadmap aims to push dairy sustainability forward with a new project to standardize carbon footprint tools. For this the Carbon Footprint Working Group has reviewed the current carbon calculators available to dairy farmers and is working to create standardization across the market, ensuring reliability and consistency in reporting for the UK dairy industry. The group plans to standardize emissions reporting, then investigate the calculation of carbon sequestration and its value to the dairy sector. Currently carbon measuring tools can vary greatly in what they measure and how, which can mean issues in terms of providing consistency. The output from the Working Group will standardize metrics and reporting across tools, resulting in the development of a UK-wide carbon footprint estimate. This will be used to track progress, support discussion with policymakers and provide evidence of the work being undertaken within the dairy sector to reduce the environmental footprint. With many dairy farmers now collecting and inputting data into a number of different carbon calculating tools, questions are being raised about what carbon reports mean for farmers, their reliability and how these can be used to support the drive to Net Zero. The UK Dairy Roadmap is a cross-industry initiative founded in 2008 that works across the whole dairy supply chain to drive forward the sustainability of the entire UK dairy sector, from farm to fork.
