Recently came across the below chart, which illustrates the weak correlation in company-specific ESG ratings from different providers (which I wrote about earlier this week). Even though the below uses slightly different data sets than my previous post, the R² is remarkably similar. I’ve heard other experts reference correlations in .3 to .4 range, which seems consistent with the below and my previous post. I believe the takeaway is the same: the scores are directionally similar (the below dots generally move from bottom left to upper right), but the correlation is relatively loose.
