13 Aug 2020 --- Plant-based nutrition leader Upfield will introduce on-pack carbon labeling on 100 million packs of its spreads, margarines, butters and creams by the end of 2021. The carbon labels are designed to inform consumers about the environmental impact of the foods they purchase, which research suggests can be a key differentiator in purchasing decisions. An independent assessment found that Upfield’s plant-based margarines and spreads boast a 70 percent smaller carbon footprint on average than dairy butter.
