This Policy Brief accompanies the report to the Human Rights Council called “Businesses, Planetary Boundaries and the Right to a Clean, Healthy and Sustainable Environment” (A/HRC/55/43). That report focuses primarily on State obligations to protect the right to a clean, healthy and sustainable environment from harms caused by businesses. It also includes an annex of good practices, whereas this Policy Brief is akin to a report on bad practices—business activities that have caused or contributed to human rights abuses specifically related to the right to a healthy environment.
