Application of novel technologies to reach net-zero greenhouse gas emissions in the fresh pasteurised milk supply chain: A review

Abstract

This review assesses the potential of three novel technologies (3-nitrooxypropanol, ultraviolet C light cold pasteurisation and biochar) to reduce the carbon footprint produced by the fresh milk supply chain at global level. In addition to the adoption of these technologies: (i) new policies should enhance the development and implementation of international standards to optimise the quality and safety of such technologies whilst facilitating their traceability; (ii) dairy firms and technology start-ups should benefit from worldwide emissions trading systems to limit technology implementation costs; and (iii) consumers could participate in the net-zero challenge by adopting easy-to-apply sustainable practices, thus reducing their milk carbon footprint.
