FAQ - Environmental Performance Index (EPI): Can I assemble the releases of the EPI into a time series or panel dataset?
Posted: Thu Jul 25, 2024 1:34 pm America/New_York
No. The underlying methodology and data change between versions of the EPI, so it is not appropriate to assemble the scores from each release into a time series.
For researchers interested in time series analysis, we recommend working with individual indicators or issue categories for which longitudinal observations are available, rather than the full EPI scores.
