Dataset for "The Nitrogen Sustainability Index: A Multidimensional Framework for Global Nitrogen Governance"

Using the Entropy Weight Method (EWM) and 24 globally available indicators, we evaluated 135 countries from 2000 to 2022. The NSI's non-compensatory aggregation ensures that deficiencies in one domain are not masked by successes in others, providing a more equitable assessment.

This dataset contains all source data, EWM-derived scores, and resulting graphics. To ensure transparency and replicability, the EWM was applied in a detailed, step-by-step manner, with all methodological steps and equations provided in both the dataset and the manuscript.
