Executive Summary

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.

Key Takeaways

  • ✓ 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.
  • ✓ Taxonomy alignment underpins green bond eligibility criteria, green asset ratio reporting, and increasingly sustainable finance disclosure more broadly, even for instruments that are not use-of-proceeds restricted.
  • ✓ Taxonomy alignment should be assessed and documented at the individual activity or project level, since asserting alignment only at the portfolio or instrument level, without underlying project-level support, does not withstand independent scrutiny.

Definition

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.

Why It Matters to the Financial Model

Taxonomy alignment underpins Green Finance eligibility criteria, Climate Finance KPIs' green asset ratio reporting, and increasingly Sustainable Finance disclosure more broadly. It should be assessed and documented at the individual activity or project level rather than asserted only at portfolio or instrument level.

Frequently Asked Questions

What is taxonomy alignment?

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.

What does taxonomy alignment underpin in practice?

Green bond eligibility criteria, green asset ratio reporting, and increasingly sustainable finance disclosure more broadly, having become the common reference point for green and sustainable finance eligibility even where the specific instrument is not use-of-proceeds restricted.

At what level should taxonomy alignment be assessed?

At the individual activity or project level, since asserting alignment only at the portfolio or instrument level, without underlying project-level support, does not withstand independent scrutiny.

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.

Green Finance

Green finance is the use-of-proceeds subset of sustainable finance, capital raised through an instrument, most commonly a green bond or green loan, whose proceeds are contractually restricted to a defined list of eligible environmental projects. This guide covers how eligibility criteria are defined and applied, how proceeds tracking works in practice, and the reporting obligations a green-labelled instrument carries beyond a standard, unrestricted loan or bond.

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.

Climate Finance KPIs

Climate finance performance is read through a small set of KPIs, mobilisation ratio, cost per tonne abated, green asset ratio, and avoided emissions, each capturing a different dimension of a climate investment's effectiveness and none sufficient as a standalone measure. This guide sets out how each KPI is defined, how they should be disclosed together as a system rather than in isolation, and the common ways each metric is calculated inconsistently across the industry.
