The Global 100 Index

Corporate Knights’ 2022 ranking of the world’s 100 most sustainable corporations is based on a rigorous assessment of nearly 7,000 public companies with revenue over US$1 billion. All companies are scored on applicable metrics relative to their peers, with 50% of the weight assigned to Clean Revenue and Clean Investment. Nine of the indicators have fixed weights; the rest are assigned weights according to each industry’s relative impact in relation to the overall economy. After quantitatively analyzing data for 23 key performance indicators, using the Corporate Knights methodology, this year’s overall scores were converted to letter grades.
