TIME Magazine’s TIME 100 list profiles the 100 most influential people each year. For the first time, TIME magazine is shining the spotlight on corporate influence, too, with its inaugural list of the world’s most sustainable companies. Stantec, WSP, Acciona, and Sacyr are a few that made the top 10.

The list of 500 companies was put together in conjunction with the data firm Statista. Beginning with a pool of 5000 of the world’s largest companies, the evaluation process used over 20 key data points and a rigorous four-step process to whittle the number down to just 500. 

The process involved:

1. Excluding non-sustainable businesses involving fossil fuels or deforestation, or those associated with environmental catastrophes.
2. Assessing the company’s external sustainability ratings and commitments, such as adhering to the UN Global Compact or participating in the UNFCCC Race to Zero. 
3. Evaluating sustainability reports, including whether the company had filed an Environmental, Social, and Governance (ESG) report for 2022 and assessing report assurance and compliance.
4. Looking at key environmental and social stewardship indicators, including emissions, renewable energy use, gender diversity, and work safety.

Companies were scored out of a possible 100 points, with the top-scoring 500 companies making the list.
