Green Finance
Executive Summary
Key Takeaways
- ✓ Green finance restricts an instrument's proceeds by contract to a defined list of eligible environmental projects, distinguishing it from the broader sustainable finance frame and from sustainability-linked instruments, which adjust pricing to performance rather than restricting use of proceeds.
- ✓ Eligibility criteria, most commonly drawn from a recognised green bond or green loan principles framework or a formal taxonomy, should be applied and documented project by project, not asserted at the instrument level without underlying support.
- ✓ Proceeds tracking, typically through a dedicated sub-ledger or register, is necessary to demonstrate ongoing compliance with the use-of-proceeds restriction over the instrument's life, not only at issuance.
- ✓ Green-labelled instruments typically carry incremental reporting obligations, an allocation report showing where proceeds were deployed and an impact report showing the environmental outcome achieved, beyond what a standard, unrestricted loan or bond requires.
- ✓ A financial model should treat a green instrument's proceeds as earmarked for its eligible use, and should flag, rather than obscure, any period in which unallocated proceeds are held pending deployment to an eligible project.
Objective¶
This guide covers the use-of-proceeds mechanics specific to green finance within Climate Finance & Climate Financial Modelling, distinct from the broader Sustainable Finance frame.
Eligibility Criteria¶
Green finance instruments restrict proceeds to a defined list of eligible environmental projects, with eligibility criteria most commonly drawn from a recognised green bond or green loan principles framework, or a formal green taxonomy's technical screening criteria (see Taxonomy Alignment). Eligibility should be applied and documented at the individual project level, since asserting eligibility only at the level of the instrument as a whole, without project-by-project support, does not withstand independent scrutiny.
Proceeds Tracking¶
Demonstrating ongoing compliance with a use-of-proceeds restriction requires proceeds tracking, typically through a dedicated sub-ledger or register, over the full life of the instrument rather than only at issuance. This tracking should show, at any point, which eligible projects have received allocated proceeds and how much of the instrument's total proceeds remain unallocated.
Reporting Obligations¶
A green-labelled instrument typically carries two incremental reporting obligations beyond a standard, unrestricted loan or bond: an allocation report, showing where proceeds were actually deployed against the eligible project list, and an impact report, showing the environmental outcome achieved by that deployment. Both should be modelled as recurring obligations with their own preparation cost and timeline, not a one-time disclosure at issuance.
Treatment of Unallocated Proceeds¶
Proceeds held pending deployment to an eligible project represent a period where the use-of-proceeds restriction is not yet actively satisfied. A model should flag this state explicitly, showing the unallocated balance and its expected deployment timeline, rather than presenting the instrument as fully allocated from issuance.
Common Construction Pitfalls¶
Eligibility asserted at instrument level only. Claiming green eligibility without project-by-project documentation does not withstand independent scrutiny.
Proceeds tracking treated as a one-time issuance exercise. Failing to track allocation on an ongoing basis over the instrument's life risks an undetected compliance gap.
Unallocated proceeds obscured. Presenting an instrument as fully deployed when a material unallocated balance remains overstates the degree of use-of-proceeds compliance actually achieved.
Recommended Practices¶
- Document eligibility against the applicable framework or taxonomy at the individual project level.
- Maintain ongoing proceeds tracking through a dedicated sub-ledger or register for the instrument's full life.
- Model allocation and impact reporting as recurring obligations with their own cost and timeline.
- Flag unallocated proceeds explicitly rather than presenting the instrument as fully deployed by default.

Frequently Asked Questions
What distinguishes green finance from the broader sustainable finance frame?
Green finance restricts an instrument's proceeds by contract to a defined list of eligible environmental projects, while sustainable finance more broadly integrates ESG factors into decisions without necessarily restricting use of proceeds to a specific eligible list.
How are green finance eligibility criteria typically defined?
Most commonly drawn from a recognised green bond or green loan principles framework, or a formal green taxonomy's technical screening criteria, and should be applied and documented at the individual project level, not asserted only at the level of the instrument as a whole.
What is proceeds tracking, and why does it matter?
The practice of tracking a green instrument's proceeds, typically through a dedicated sub-ledger or register, to demonstrate ongoing compliance with the use-of-proceeds restriction over the instrument's full life, not merely at the point of issuance when eligible projects are first identified.
What reporting obligations does a green-labelled instrument carry beyond a standard loan or bond?
Typically an allocation report showing where proceeds were actually deployed against the eligible project list, and an impact report showing the environmental outcome achieved, both incremental to the financial reporting a standard, unrestricted instrument would require.
How should unallocated proceeds be treated in the model?
As an explicitly flagged, temporary state rather than obscured, since a green instrument's proceeds held pending deployment to an eligible project represent a period where the use-of-proceeds restriction is not yet actively satisfied and should be visible to a reviewer.

Climate Finance & Climate Financial Modelling
Climate finance is the mobilisation and allocation of capital toward mitigation, adaptation, and transition activity, and climate financial modelling is the discipline of representing that activity's cash flows, risk, and concessionality in a financial model. This page is the hub for the Knowledge Centre's climate finance content: how sustainable, green, and transition finance are distinct but related capital allocation frames, how a climate investment model differs from a standard project or corporate model in its treatment of concessional capital and additionality, how physical and transition climate risk are quantified at portfolio and entity level, and how carbon markets, climate-sector investment, and institutional governance practice build on these foundations as this domain expands.
Sustainable Finance
Sustainable finance is the broadest of the climate-adjacent capital allocation frames, financial activity that integrates environmental, social, and governance factors into investment and lending decisions generally, rather than restricting capital to a defined list of eligible green projects or a defined transition pathway. This guide sets out sustainable finance's scope, sustainability-linked instruments (where terms adjust to performance against ESG-linked KPIs rather than restricting use of proceeds), and its relationship to taxonomy-based disclosure.
Green Bond
A green bond is a use-of-proceeds debt instrument whose proceeds are contractually restricted to a defined list of eligible environmental projects, with eligibility typically defined by a recognised green bond principles framework or a formal taxonomy. It is structurally distinct from a sustainability-linked bond, whose proceeds are unrestricted but whose pricing is instead contingent on the issuer meeting defined ESG-linked performance KPIs.
Taxonomy Alignment
Taxonomy alignment measures whether an economic activity meets a defined green or sustainable taxonomy's technical screening criteria, a formal, codified eligibility standard rather than a general environmental claim. It has become the common reference point underpinning green bond eligibility, green asset ratio reporting, and increasingly sustainable finance disclosure more broadly, even for instruments that are not use-of-proceeds restricted.
