A green loan is a form of financing that enables borrowers to use the proceeds exclusively to fund projects that make a substantial contribution to an environmental objective. This page walks a prospective borrower through the full application journey — who is eligible, how the market is governed, what actually makes a loan "green", and what to prepare, in what order.
What a green loan is, and why a borrower would choose one.
A Green Loan is any loan instrument made available exclusively to finance or re-finance, in whole or in part, new and/or existing eligible green projects. It supports environmentally sustainable economic activity, and helps borrowers communicate the greening of their operations and supply chain — often on more favourable terms than a conventional loan.
The market standard that defines what counts as a "green" loan is the Green Loan Principles (GLP), issued jointly by the International Capital Market Association (ICMA) and the Loan Market Association (LMA). The rest of this page follows that framework end-to-end — from who can borrow, through governance, defining characteristics, the application steps, paperwork, an indicative timeline, and who to reach out to along the way.
The GLP framework is borrower-agnostic — any of the following can access a green loan, provided the underlying project qualifies (see below).
Corporates & Private Businesses
Established companies borrowing directly from a bank to finance an eligible green project on their own balance sheet.
Micro, Small & Medium Enterprises (MSMEs)
Smaller businesses typically accessing green finance through an on-lending financial intermediary rather than directly from a development finance institution.
Financial Institutions & NBFCs
Banks and non-bank financial companies that draw a green loan themselves in order to on-lend it as green finance to smaller downstream borrowers.
The project itself must also qualify
Regardless of who the borrower is, the underlying project must clearly fall under an eligible green category:
The Green Loan Principles (GLP) are the standard framework for the green loan market, administered through a partnership of three major regional trade associations. There is no single global regulator — these bodies jointly maintain and update the principles as the market grows.
The three governing associations
Loan Market Association (LMA)
The authoritative voice of the EMEA (Europe, Middle East, and Africa) syndicated loan market.
Asia Pacific Loan Market Association (APLMA)
Represents the interests of the loan market across the Asia-Pacific region.
Loan Syndications and Trading Association (LSTA)
The primary trade association for the corporate loan market in the United States.
Key governance characteristics
Collaborative Development
Developed by an experienced working party of representatives from leading financial institutions active in the syndicated loan market.
Voluntary Framework
Recommended guidelines rather than a mandatory regime, designed to be applied by market participants on a deal-by-deal basis.
Alignment with ICMA
Developed with ICMA's support, and built on the Green Bond Principles (GBP) for consistency across global green finance markets.
Market Integrity
Clarifies when a loan may be categorised as "green" and maintains a consistent methodology across the market.
What actually distinguishes a green loan from an ordinary loan — the four core principles of the GLP.
Use of Capital for Green Purposes
The loan must be used exclusively for projects that fall under the "green" category — renewable energy, energy efficiency, clean transportation, green buildings, resource circularity, sustainable agriculture, and so on.
Project Evaluation & Selection
The enterprise must clearly describe the project selection criteria, environmental risks, and the anticipated environmental benefits.
Management of Loan Proceeds
Loan proceeds must be tracked separately or managed transparently to ensure they are not used for unintended purposes.
Transparent Periodic Reporting
The enterprise must commit to providing periodic reports to the bank on project progress and actual environmental outcomes — avoided emissions, energy savings, and so on.
How lenders evaluate a loan
Quantitative metrics banks typically rely on when reviewing applications.
| Criteria | Meaning | Example |
|---|---|---|
| Emission Intensity (gCO₂/kWh) | The emission level per unit of energy or product produced. | <100 gCO₂/kWh for approved renewable energy |
| Avoided Emissions | Comparison with older technologies or baseline methods to calculate CO₂e reduction. | Using biomass instead of FO oil, reducing 1,500 tons of CO₂ per year |
| Technical Green Certification | Enhances project reliability and accelerates the validation process. | ISO 14064 (GHG inventory), EDGE, LEED (buildings), PCAF (finance) |

Technical & environmental documentation
Loan application documentation
Common mistakes that cause applications to fail
In practice, many businesses are turned down not for lack of capability, but for inadequate technical preparation.
Watch out for these
An indicative sequence and duration for a first-time borrower. Actual timing varies with borrower readiness, loan size, and the lending bank's own process — treat this as a planning guide, not a guarantee.
Identify a green-eligible project
~1–2 weeksConfirm the project falls under an eligible green category before approaching any lender.
Preliminary emissions & reduction assessment
~2–4 weeksCalculate the emissions baseline and reduction potential, ideally with independent verification (ISO 14064-1 / ISO 14067).
Prepare technical & loan application documents
~3–6 weeksCompile the Document Checklist above — technical, environmental, and financial documentation.
Bank selection, appraisal & credit approval
~4–8 weeksApproach one or more banks with a green loan programme; the bank appraises the application through its own credit process.
Loan signing & disbursement
~1–2 weeksLegal documentation is signed and funds are disbursed, often in stages tied to project milestones.
Monitoring & periodic reporting
Every 6–12 months, ongoingReport implementation progress, actual emissions results, and any newly acquired certifications for the life of the loan.
For direct bank financing, approach a bank with an established green loan programme. For development-finance-backed routes, IFC is a common option.
IFC eligibility, in brief
IFC does not lend directly to MSMEs or individual entrepreneurs — but many of its investment clients are financial intermediaries that on-lend to smaller businesses.
