The Standards

What are the IFC Performance Standards?

The IFC Performance Standards on Environmental and Social Sustainability are eight standards (PS1–PS8) that govern how the International Finance Corporation — and, by adoption, the world’s major project-finance banks — assess and manage the environmental and social risks of the projects they finance. Updated in 2012 and refreshed through subsequent guidance notes, they have become the de facto global benchmark for high-impact project due diligence.

PS1 covers risk assessment and management. PS2 covers labour. PS3 covers resource efficiency and pollution. PS4 covers community health and safety. PS5 covers land acquisition and resettlement. PS6 covers biodiversity conservation and the sustainable management of living natural resources. PS7 covers Indigenous Peoples. PS8 covers cultural heritage.

Why PS6 dominates the nature conversation. It is the biodiversity standard with real consequences: failure to comply means the project doesn’t get financed, doesn’t get insured, and in many jurisdictions doesn’t get permitted.

Performance Standard 6

The biodiversity standard.

PS6 sets requirements for protecting and conserving biodiversity, maintaining the benefits from ecosystem services, and promoting sustainable management of living natural resources. It distinguishes between three habitat tiers, each with progressively stricter requirements:

The Critical Habitat assessment is the make-or-break diligence step for projects in mining, infrastructure, energy, and large-scale agriculture. A site within or adjacent to a Key Biodiversity Area or known habitat for a Critically Endangered species triggers a fundamentally different financing pathway.

The Mitigation Hierarchy

Avoid, Minimise, Restore, Offset — in that order.

The mitigation hierarchy is the operating logic of PS6. Project sponsors must demonstrate they have worked through the steps in sequence — an offset cannot stand in for a failure to avoid impacts where avoidance was feasible.

01
Avoid

Site away from sensitive areas, redesign the project, defer activity. The strongest defensible position with lenders.

02
Minimise

Reduce intensity, scale, duration of unavoidable impacts. Engineering controls, seasonal restrictions, footprint reduction.

03
Restore

Active rehabilitation of disturbed land — revegetation, soil rehabilitation, hydrological restoration during and after operations.

04
Offset

Last resort, last step. Net-gain biodiversity offset for critical habitat impact, with like-for-like or higher-value rules and long-term stewardship.

Beyond IFC

Why PS matters far beyond the IFC.

The Performance Standards have been formally adopted — with little or no modification — by the Equator Principles (EP4 is the current version), a voluntary framework signed by the world’s major project-finance banks across 38 countries. Any project the bank finances above defined thresholds must demonstrate PS-level due diligence.

Most bilateral and multilateral DFIs (FMO, OPIC/DFC, EBRD, ADB, AfDB) align their own safeguards explicitly to the PS. Major export credit agencies have followed. The OECD Common Approaches reference them. Insurers including the Berne Union members use them in underwriting decisions. The result: even projects that never see an IFC dollar are commonly held to PS standards by the time they close.

For project sponsors, assuming any meaningful debt finance is involved, planning a project to PS6 from inception is dramatically cheaper than retrofitting compliance after a lender raises a finding.

IFC PS & TNFD

PS6 and TNFD share most of the underlying biodiversity and ecosystem-services concepts — the IFC’s 2012 framework was a direct input to the TNFD’s LEAP design. The difference is the audience and the binding force:

For a company already complying with PS6 on its assets, most of the data and governance infrastructure needed for TNFD is already in place. Conversely, a TNFD-first company entering project finance can usually pivot a LEAP assessment into a PS6-aligned ESIA faster than starting from scratch.

How Climate Decode Helps

PS6-aligned project development.

Climate Decode supports project sponsors and lenders across the lifecycle — from screening through ESIA to long-term biodiversity management.

01
Pre-financing Screening

Critical habitat overlay using IBAT, KBA and Red List data. Early-stage red-flag identification — before site selection is locked in.

02
ESIA & Biodiversity Action Plan

PS6-compliant Environmental and Social Impact Assessment, mitigation hierarchy plan, and Biodiversity Action Plan that lenders sign off on.

03
Offset Design & Stewardship

For unavoidable critical-habitat residuals: like-for-like offset design, long-term stewardship arrangements, and TNFD/CSRD-grade disclosure of the resulting net-gain claim.

Take the friction out of PS6 compliance.

If your project is going for IFC, EBRD, ADB, FMO, or any Equator Principles bank funding — the PS6 work is non-negotiable. We’ve done it across mining, energy, infrastructure, and agribusiness on three continents. Get it right at design stage and the financing process is dramatically cleaner.
