This chapter examines corporate responsibilities and accountability to anticipate and redress human rights violations relating to the environment in their spheres of operations. After this introduction, section 2 examines the drivers and contours of the growing recognition of corporate accountability relating to environmental damage. Section 3 unpacks the key scope and content of emerging human rights obligations of corporations to protect the environment. These obligations are as follows: participation, accountability, non-discrimination and equality, empowerment and legality (the PANEL principles). By implementing the PANEL principles in the design, approval, finance and implementation of their operations and projects, business enterprises can proactively anticipate and tackle environmental risks across their entire business value chain. Section 4 highlights practical challenges that must be addressed by national authorities and business enterprises in order to fully translate these norms to reality. Section 5 is the concluding section.
