Greenhouse gas emissions and water usage are both critical environmental indicators used to assess the impact of dietary patterns and food production, as evidenced by their frequent co-analysis in literature [1], [2] and their role as distinct metrics in environmental impact databases [3]. These concepts are often discussed in the context of tradeoffs, where improvements in one may not correlate with improvements in the other [4], [5], necessitating the use of both to capture a comprehensive environmental footprint [6].

Measurement of diets that are healthy, environmentally sustainable ... frontiersin.org 3 facts
claimEnvironmental indicators that have existed the longest in the literature and have been the most frequently analyzed are climate-related outcomes, specifically GHG emissions (33.3%), land use (15.2%), and water use (13.6%).
referenceAleksandrowicz et al. (2016) conducted a systematic review on the impacts of dietary change on greenhouse gas emissions, land use, water use, and health.
claimShifting dietary patterns involves tradeoffs between policy goals, such as a shift to plant-based foods reducing greenhouse gas emissions while potentially resulting in higher water usage.

claimEnvironmental indicators for diets are not always positively correlated, meaning that dietary changes that improve one indicator, such as greenhouse gas emissions, do not guarantee improvements in other indicators, such as water use.
claimGreenhouse gas emissions (GHGE) alone are considered insufficient to capture total environmental impact because other indicators, such as biodiversity loss and water use, represent important environmental impacts that must be accounted for.

measurementThe Agribalyse 3.1.1 database utilizes 14 specific metrics to assess environmental impact: greenhouse gas emissions (kg CO2 eq), exposure ionizing radiation (kg U235 eq), photochemical ozone formation (kg NMVOC eq), ozone depletion (Freon-11), emission of particulate matter (mortality due to particulate matter emissions), acidification (mol H+ eq), terrestrial eutrophication (mol N eq), freshwater eutrophication (kg P eq), marine eutrophication (kg N eq), freshwater ecotoxicity (CTUe), water use (m3 world eq), land use (loss of soil organic matter content in kg carbon deficit), fossils resource use (MJ), and metals and minerals resource use (kg Sb eq).
