Equator Principles
The Equator Principles are a voluntary common baseline and risk management framework for financial institutions to identify, assess and manage environmental and social risks when financing Projects. They apply globally and across industry sectors. Equator Principles Financial Institutions (EPFIs) implement the ten Principles through their internal environmental and social policies, procedures and standards.
The framework was launched in 2003 by ten founding financial institutions and has been revised as EP2 (2006), EP3 (2013) and EP4 (2020). EP4 took effect for all EPFIs on 1 October 2020 after an extended Covid-19 transition. Where older texts refer to an Equator Principles Association, that legal entity was dissolved in 2024; from 2024 the reference is read as the collective group of Signatories.
How the Equator Principles are used on bank project finance desks
On project finance desks the Equator Principles determine whether a proposed facility is in scope, which standards apply, and what independent review, covenants and monitoring are required before and after financial close. Scope covers five product types: Project Finance Advisory Services; Project Finance; Project-Related Corporate Loans; Bridge Loans; and Project-Related Refinance and Project-Related Acquisition Finance, each subject to stated cost, commitment, tenor and control thresholds.
Material thresholds include Project Finance and advisory mandates where total Project capital costs are USD 10 million or more, and Project-Related Corporate Loans where the majority of the loan relates to a Project under the client's Effective Operational Control, aggregate loan and EPFI commitment are each at least USD 50 million, and tenor is at least two years. Expansions or upgrades of existing Projects are in scope even though the Principles are not applied retroactively to legacy financings. Sponsor groups and EPC counterparties supply the underlying E&S studies; EPFIs require categorisation, assessment, management systems, stakeholder engagement, grievance mechanisms, and often an independent engineer or independent E&S review.
Applicable standards and Designated Countries
Principle 3 distinguishes Designated and Non-Designated Countries. Designated Countries are OECD members that also appear on the World Bank High Income list, used as a proxy for robust environmental and social governance. In Non-Designated Countries, the IFC Performance Standards are the primary underpinning standards, a structure introduced with EP2 and carried forward. In Designated Countries, host-country law is the baseline, with EP4 broadening certain assessments such as climate change risk and human rights.
The ten Principles run from review and categorisation through assessment, applicable standards, management systems and action plans, stakeholder engagement, grievance mechanisms, independent review, covenants, independent monitoring and reporting, and EPFI reporting and transparency. Full Signatories must undertake an Independent Review of implementation at least once every three years. The Principles are not a credit rating, not a substitute for host-country permits, and not a collective boycott mechanism; each EPFI applies them independently under applicable competition law.
