Environmental impact assessment of dietary scenarios: a comparison of methodological aspects

Summary

Background
Dietary patterns have manifold impacts on the environment.
• However, studies that assess dietary patterns operate with varying methodological approaches and underlying assumptions, which evoke different, and occasionally even contradicting, results.
• This leads to uncertainty regarding what should or should not be eaten, especially with regard to animal-source food (ASF) and production types (e.g. conventional or organic).
• Therefore, to adequately interpret results, it is necessary to interpret these in the context of the respective methods used and assumptions made.
