Tesco and Kepak have introduced a new beef line with a carbon footprint up to 23% lower than standard products. The reduction comes from improved cattle genetics, better nutrition, and optimized grassland management, allowing animals to reach slaughter weight faster. While verified by the Carbon Trust, experts note that efficiency gains per animal differ from total emission reductions. The initiative highlights the tension between improving production efficiency and the broader need to reduce total livestock numbers to meet national climate targets.
