Is cell-based meat a climate solution for Canada?

Interpreting lifecycle footprints within the domestic agri-food context

Abstract

Interest and technological know-how in cell-based meat production has grown tremendously in recent years. The appeal is wide ranging, but two main drivers include: i) the possibility of producing edible meat without requiring the slaughter of sentient animals; and ii) the potential to significantly reduce the environmental impact of animal agriculture. Owing to these potential benefits, proponents have called for major government investments in cell-based meat to further develop the technology and help launch the industry. This article critically examines the environmental promise of cell-based meat, focussing specifically on its potential role in climate change mitigation, and specifically within the context of Canada’s agri-food sector. The analysis is founded upon a comparison of available life cycle greenhouse gas assessments of cell-based and conventional meat, supplemented with contextual data about the Canadian agri-food sector. Cell-based meat in Canada is found to have a likely carbon footprint similar in scale to poultry meat, pork, and beef from dairy cattle, though considerably lower than meat from beef cattle. Alongside these findings and additional contextual factors pertaining to Canada’s agri-food sector, the paper argues that cell-based meat is best understood as one tool among many which could potentially support greenhouse gas emissions reductions in domestic food production if supporting conditions are met, not a silver bullet climate solution obtained by fully replacing conventional meat.
