About the data
The figures are exclusive to this study, due to being dependent on the relative performance of the other companies and cannot be used in isolation.
Methodology
This figure was calculated by finding the mean average for every metric of each company over the years 2017, 2018 and 2019.
Each company was then ranked by these averages from best (1) to worst (6) for all 12 ESG metrics in the study.
All 12 metric scores are then accumulated to form the overall ESG score for every company.
The lower the score, the better the ESG performance.
