UBC Climate-Friendly Label recipe analysis, 2023-2024 : Student WorkLearn 2023-2024 Report Marfatia, Sharon

Abstract

Research Objectives and Methodology The core objective of Sharon's work was to refine and extend the environmental impact analysis of food services at UBC. This involved incorporating a new land use metric into the assessment framework, re-evaluating baselines for greenhouse gas (GHG) emissions, stress-weighted water use and embodied nitrogen. A multi-faceted approach was employed, leveraging both existing and dynamic data analysis techniques. Key methodologies included: • Enhancing environmental impact assessments by integrating land use factors with existing metrics. • Automating the classification of food items into GHG impact categories and standardizing unit measurements to streamline procurement data analysis. • Deploying machine learning models, specifically focusing on natural language processing (NLP), to classify and analyze UBC Food Services data, with the objective to use UBC Food Services data to predict CF label assignments at other venues where detailed recipe information is unavailable. Major Findings The application of these methodologies yielded several significant findings: • The introduction of a land use factor provided a more comprehensive reflection of food choices' environmental impacts. • Automation of data categorization and unit standardization substantially improved the efficiency of data analysis processes. • The NLP-based machine learning model demonstrated a robust capacity for classifying food service data (final test score of 0.7356 = 73.56%), a positive prospect towards deploying the label more effectively. Significant Conclusions As we move forward, it is clear that the insights and methodologies developed have the potential to significantly influence both the academic and operational landscapes of food services at UBC and beyond. The enhanced analytical capabilities have not only improved the precision of environmental impact assessments but have also paved the way for more informed decision-making regarding food procurement and sustainability practices.
