They evaluated the remaining 350 companies using key environmental, social, and governance performance indicators, including waste productivity, CEO-to-average-worker pay ratio, leadership diversity, and employee turnover. The companies were then scored, relative to their same-sector peers. (A different set of performance indicators was used for companies in each industry, depending on recent reporting trends in each industry group.)
Corporate Knights collected data for the project primarily from Bloomberg and through direct engagement with the 350 companies.
“No corporate sustainability assessment is perfect,” Morrow says. “Each has its own strengths and weaknesses, but in terms of what matters most–transparency, rules-based, and sophistication–we feel the Global 100 is the most complete sustainability ranking in the world.”
