The agri-food system is responsible for approximately one-quarter of all global greenhouse gas emissions. In an effort to increase environmental transparency and mitigate carbon emissions, a small number of food and drink brands are incorporating carbon footprint labelling on-pack. In 2019, oat drink producer Oatly introduced carbon footprint data via a partnership with Carbon Cloud. In early 2020, meat alternative brand Quorn started introducing carbon footprint data, certified by the Carbon Trust, for some its products. A few months later, in August 2020, Upfield – in partnership with Quantis – announced plans to introduce on-pack carbon labelling to 100 million packs of margarine and spreads by the end of 2021.
