AMS Nest Supply Chain Audit Kim, Victoria; Kwan, Julian; Nakada, Casey; Rosazza-Pela, Olivia


The AMS Nest serves food for over 60,000 students each year, yet there are few studies that can be applied to estimate the Nest’s carbon footprint and target policies towards emissions reduction. This paper uses two multivariate regression models to estimate the impact of international sourcing and travel distances on the GHG emissions generated by the Nest’s food supply chain. Using a sample of 61 food products ordered by the AMS over 8 months (UBC’s winter session), we find that 1) sourcing products from outside British Columbia contributes the most to transportation emissions, and 2) consuming animal-based products contributes the most to total emissions, increasing by 6.5 tonnes of GHGs per animal-based product type. Simulating an adjusted supply chain by switching product sources to viable foodservice sources within BC reduced transportation emissions by 56%. Based on our results, we recommend new procurement policies that source products within BC in the short-term and reduce consumption of animal-based products in the long-term in order to effectively mitigate carbon emissions generated by the Nest’s supply chain.
