Scientists on meat taxation and climate change

The international research team behind this article calls for an increased climate policy focus on reducing ruminant meat consumption. They argue that climate negotiations thus far have paid too little attention to the role of livestock when discussing greenhouse gas mitigation. Methane from ruminants is the largest human-related source of the greenhouse gasses. As such, reducing ruminant populations is the most effective way to cut methane emissions and would also reduce CO2 emissions resulting from forest clearance for livestock farming. The livestock sector as a whole contributes around 14.5 % of all human-caused GHGs according to the latest FAO report) – a figure that includes overall GHG emissions, not just methane.

The study argues that the best option would be to raise the price of meat through taxes or an emissions trading regime so as to moderate consumption patterns and emphasise that demand reduction offers greater greenhouse gas reduction potential than other efforts such as increasing livestock feeding efficiency or crop yields per acre – although a combination of consumption and production side measures could deliver the greatest mitigation potential. Reducing ruminant populations is also said to bring other potential benefits for food security, human health and environmental conservation involving water quality, wildlife habitat and biodiversity.  

Abstract

Greenhouse gas emissions from ruminant meat production are significant. Reductions in global ruminant numbers could make a substantial contribution to climate change mitigation goals and yield important social and environmental co-benefits.

While some of the food system challenges facing humanity are local, in an interconnected world, adopting a global perspective is essential. Many environmental issues, such as climate change, need supranational commitments and action to be addressed effectively. Due to ever increasing global trade flows, prices of commodities are connected through space; a drought in Romania may thus increase the price of wheat in Zimbabwe.
