FAQ - Environmental Performance Index (EPI): Can I assemble the releases of the EPI into a time series or panel dataset?

[SEDAC - evlukang]

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.
