The $3.8 billion Dakota Access Pipeline (DAPL) has proved to be a highly controversial project, with its impacts exceeding the wildest expectations of investors. It was accompanied by protests, court cases, accusations of political interference and even a presidential memorandum. The banks financing the project claim to have adhered to the Equator Principles (EP or the Principles), a credit risk management framework for determining, assessing and managing environmental and social risks in projects. They have been adopted by 92 financial institutions in 37 countries, covering over 70% of project finance debt in emerging markets. An Equator Principles Financial Institution (EPFI) will require its clients – the borrowers – to conduct environmental and social impact assessments for each project.
