The WWF Paper Company Environmental Index measures how transparent companies are via a number of questions, such as:
- does the company have ISO 14001 certification or equivalent for its mills?
- is the company reporting according to a standard recommended in the Global Reporting Initiative guidelines?
- has the company made its official fibre sourcing policy and actual percentage of recycled and credibly certified fibre use available to the public?
- how comprehensively has the company made air, water and waste emissions data publicly available?
