To provide a database with observed responses to climate change for multidisciplinary studies.

To provide quantitative metrics for evaluating a country's environmental performance in different policy categories relative to clearly defined targets.

To provide information on global land use for research on human-environment interactions.

To make the acquisition, comparison and analysis of sustainability indicators easier by compiling them in a single database, incorporating multiple country codes, and condensing the indicator descriptions into short methodological summaries in an accompanying data dictionary.
