A research project to assess global greenhouse gas emissions associated with the Scottish dairy supply chain and identify main opportunities to reduce emissions while maintaining or improving economic productivity. The study is the first of its kind to estimate emissions from a whole country's dairy supply chain and apply the latest dairy footprinting methodologies.
