Introducing a comprehensive and configurable tool for calculating environmental and social footprints for use in dietary assessments

Summary

This paper, authored by researchers at the Swedish University of Agricultural Sciences and affiliates, introduces a configurable computational tool for assessing the environmental and social footprints of diets. The tool is designed to integrate multiple sustainability dimensions — likely including climate impact, land use, and social indicators — into dietary assessment workflows, addressing a recognised gap in the availability of comprehensive, flexible life cycle–based tools for food and nutrition research. The authors appear to demonstrate the tool's configurability across different food systems, datasets, and impact methodologies, offering it as a resource for researchers and practitioners conducting diet-sustainability analyses.

UK applicability

The tool is likely applicable to UK dietary assessment contexts, particularly given growing policy interest in sustainable diets within the UK's National Food Strategy and NHS frameworks; however, users would need to adapt or replace underlying environmental impact datasets to reflect UK-specific supply chain conditions and emissions factors.

Key measures

Environmental footprint indicators (e.g. greenhouse gas emissions, land use, water use); social footprint metrics; dietary impact scores per food item or dietary pattern

Outcomes reported

The study presents and validates a comprehensive, configurable software tool designed to calculate environmental and social footprints associated with dietary patterns. It likely reports on the tool's capacity to handle multiple impact categories across diverse food items and dietary scenarios.
