The study evaluates 14 articles that analyze greenhouse gas emissions and land use associated with 49 dietary scenarios, concluding that dietary change could significantly reduce environmental impact. Key methodological insights are discussed, highlighting the role of functional units and boundaries in scenario analyses. The review advocates for further research to improve understanding of dietary impact on sustainability.
