Since 2005, the Global 100 has been one of the world’s most valued and transparent rules-based sustainability ratings that emphasizes the impact of a company’s core products and services. It is the best-performing global sustainability index (ticker: CKG100), with more than 10 years of history. All publicly-traded companies with over US$1 billion in revenue are assessed across three sustainable economy key performance indicators, including % sustainable revenue and % sustainable investment. Companies engaging in “red flag” activities such as thermal coal, blocking climate policy and deforestation are disqualified. Our methodology illuminates the say-do gap. Only those companies making sustainable solutions a core part of their business offerings and allocating meaningful investments to reduce their carbon footprints make the grade.
