Re: “Growing Canada’s agri-food sector requires a sustainable approach to meet consumer demand,” (The Hill Times, March 20, p. 23). Kudos to the Canadian government for making efforts to address climate change in the agriculture sector, which is a significant source of GHG emissions. Despite Liberal MP Francis Drouin’s enthusiasm for the government’s efforts, however, they are still missing the mark. Clean technologies and efficiencies on farms are important, but the most impactful way to reduce the emissions burden from our food system is through dietary shifts—moving away from diets high in meat and dairy to ones that are more plant-based, which has many co-benefits as well. Science and expert consensus are clear on this point. The just-released report from the Intergovernmental Panel on Climate Change clearly states that sustainable healthy diets focused on plant-based foods with low environmental impact are key to reducing our emissions. Research conducted last year by Navius shows that gradually replacing 50 per cent of our animal-based foods with plant-based alternatives would reduce climate pollution by 13.5 megatonnes—far more than the goal of three to five megatonnes Drouin mentions, and more than enough for Canada to close the gap and meet its international climate obligations. A recent study published in Nature Climate Change found that reducing consumption of foods high in methane (meat, dairy, and rice) could slow global warming faster because methane is more potent but shorter-lived than carbon. If Canada truly wants to be a world leader in sustainable agriculture, it should implement policies to help shift consumption patterns that align with its own Food Guide recommendation to eat more plant foods and less animal foods as Denmark, New Zealand, and the European Union are already doing.
