Companies are increasingly encouraged to frame their sustainability activities and communication around ecological limits, as captured by concepts such as planetary boundaries, climate tipping points or local assimilative capacities. Ecological limits may serve as a scientific basis for defining environmentally sustainable companies and, moreover, inspire companies to align their product portfolios with emerging societal needs related to sustainable transformations. Although corporate environmental reporting is widely researched, little attention has, hitherto, been given to company use of the ecological limits concepts in stakeholder communication.
