Saskatchewan farmers are producing some of the least carbon-intensive crops in Canada and the world, as highlighted in a carbon life cycle analysis commissioned by the Global Institute for Food Security (GIFS) at the University of Saskatchewan (USask).
The two-part study commissioned in 2022 examined the carbon footprint from the production of five Canadian field crops – canola, non-durum wheat, field peas, durum wheat, and lentils. It compared these footprints, including their supply chain emissions, to some globally competitive regions across the world that export the same products, including Australia, France, Germany, Italy, and the United States. The results demonstrate that Canadian producers, particularly in Saskatchewan and Western Canada, are producing crops with the least amount of greenhouse gas emissions or carbon dioxide equivalents among regions compared.
“These impressive results are driven by the widespread adoption in Saskatchewan of agricultural innovations and sustainable farming practices that have significantly reduced the amount of inputs and emissions needed to farm each acre of land,” said GIFS Chief Executive Officer Dr. Steve Webb (PhD). “The sustainable practices include reduced tillage, the adoption of herbicide-tolerant canola, the variable-rate application of fertilizer, a robust crop rotation system, and the production of nitrogen-fixing pulse crops.”
The study, conducted in partnership with the Food Systems PRISM Lab in the University of British Columbia, followed established protocol for measuring the carbon life cycle of agricultural production. It compiled and reviewed data on the carbon dioxide equivalent emissions for the various activities that go into crop production including transportation, seed, fertilizer and manure inputs, crop inputs, field activities, energy emissions, and post-harvest work.
