The article tackles the different ways people define sustainability and create sustainability indicators. It explores how the math behind these indicators impacts what aspects of sustainability they measure. By studying the types of mathematical formulas used in sustainability indices, the researchers found that they affect which aspects of sustainability are captured. The choice of formula can significantly change the measured sustainability levels. The study calls for researchers to be mindful of the values embedded in these indicators, carefully select them, and clearly present results to ensure both scientists and stakeholders have accurate information about sustainability assessments.
