ISO 14030 Green Bonds: Green Loans, Taxonomy and ISO 14097

What is the ISO 14030 series on green bonds?

The ISO 14030 series is the set of international standards for green debt instruments: green bonds, green loans, a taxonomy of eligible projects, and verification. It tells you how to designate financing as “green”, how to manage and track the proceeds, and how to report on them.

It is published by subcommittee ISO/TC 207/SC 4 (environmental performance evaluation) under the common title “Environmental performance evaluation — Green debt instruments”. ISO 14030 green bonds are therefore not a separate financial product: they are ordinary bonds or loans whose issuer or borrower commits to follow this process, and to have it verified if it claims conformity.

The four parts and their status, read on iso.org on 11 November 2026:

A voluntary standard. Like any ISO standard, the series applies because an issuer, a lender or an investor chooses to refer to it, or because a contract does. We do not reproduce its paid text; this guide relies on the abstracts published by ISO and on ACG’s own practice.

How do you qualify a green bond or green loan under ISO 14030?

By following five steps that Parts 1 and 2 describe in the same terms: designate eligible projects, manage the use of proceeds, define and monitor environmental impacts, report to interested parties, and obtain validation and verification. According to iso.org, ISO 14030-1:2021 and ISO 14030-2:2021 establish principles, requirements and guidelines for each of these steps.

The taxonomy is the core of the file. ISO 14030-3:2022 defines a taxonomy of eligible investment categories for green debt instruments, bonds and loans alike. According to iso.org, it categorises economic sectors, sets eligibility criteria for projects, assets and supporting expenditures, gives guidance on adaptation by sector in Annex A, and gives examples of thresholds and exclusions in Annex B. An issuer may also use a “suitable substitute taxonomy”, according to the ISO 14030-4 abstract: this is where the EU Taxonomy comes in.

Verification is the condition for the claim. According to iso.org, ISO 14030-4:2021 sets the requirements for bodies verifying claims of conformity to ISO 14030-1 or ISO 14030-2, and to ISO 14030-3 or a substitute taxonomy. Meeting these requirements is mandatory to verify any statement by an issuer, borrower or lender that its product conforms to the series. Part 4 also covers the validation of eligibility claims and the optional use of third-party marks of conformity.

Typical example (anonymised). A food processing SME in the Meknès region wants to finance a plant to treat and reuse its process water. Its bank offers a green loan. The ISO 14030-2 file brings together: a description of the project and its eligibility category, the budget and the allocation account, two or three impact indicators (water withdrawal avoided, pollutant load discharged), their measured baseline, the monitoring frequency and the format of the annual report to the bank. The same project feeds the site’s adaptation plan for water stress, as described in our ISO 14090 and ISO 14091 guide.

What is ISO 14097 for, and why does it matter to banks and investors?

ISO 14097:2021 gives financiers a framework to assess, measure, monitor and report on how their investments and loans relate to climate change. It does not apply to the company being financed, but it explains what that company’s bank or investor will ask for.

According to iso.org, ISO 14097:2021, “Greenhouse gas management and related activities — Framework including principles and requirements for assessing and reporting investments and financing activities related to climate change”, published in May 2021 by subcommittee ISO/TC 207/SC 7, covers three topics:

• alignment of investment and lending decisions with low-carbon transition pathways, adaptation pathways and climate goals;
• impact of those decisions on achieving climate goals in the real economy, for mitigation (greenhouse gas emissions) and adaptation (resilience);
• risks that climate change poses to owners of financial assets: private equity, listed shares, bonds, loans.

To support the assessment of impact, the standard guides financiers on setting targets and metrics to track the low-carbon transition of investees, on determining investees’ transition and adaptation trajectories, and on documenting the causal link between their climate action and its outputs, outcomes and impacts. It directs their reporting to shareholders, clients, policymakers, financial supervisory authorities and non-governmental organisations. As of 11 November 2026 it is under systematic review (stage 90.60), with no new edition announced.

What this means for you. A lender following this logic needs three things from each significant client: a reliable emissions inventory, a reduction trajectory, and an analysis of the physical risks to its sites. In Morocco the same request arrives by another route: the directives of Bank Al-Maghrib, the central bank, bring climate risks into banks’ risk management and into their dealings with large borrowers, as explained in our article on the Bank Al-Maghrib climate risk directive and borrowers’ carbon data.

Green bonds in Morocco: what are the official reference points?

The Moroccan market has public milestones: a first green bond issue authorised by the Moroccan Capital Markets Authority (AMMC) in 2016, an AMMC guide on green, social and sustainability bonds in 2018, and work on a national green taxonomy mentioned by Bank Al-Maghrib.

• First issue. According to the AMMC press release dated 4 November 2016, the authority authorised the first green bond issue on the Moroccan market; the issuer named in the release is Masen.
• AMMC guides. On 9 July 2018, the AMMC announced the launch of a guide on sustainable bonds, or “Green, Social & Sustainability Bonds”. Its Publications section also offers a “Guide sur les Green Bonds” (guide on green bonds). The 2018 guide online at ammc.ma is the June 2018 version submitted for public consultation. The “Guide sur les Green Bonds” in the Publications section is the AMMC’s first guide, written with support from the IFC; the 2018 guide says it builds on it and dates it to November 2016. Neither guide cites ISO 14030 or any other ISO standard: both refer to the ICMA principles (Green Bond Principles) and to the Climate Bonds Initiative. Both describe four forms of external review (advice or second-party opinion, verification, certification, rating) and require the file submitted to the AMMC to include the reports of the independent reviewers; the AMMC does not itself assess the green quality of the issue and relies on the second opinion or the certification. The 2018 guide adds that a bond cannot be issued under the green, social or sustainability label unless an independent, qualified reviewer attests its alignment with the applicable international standards.
• National taxonomy. Bank Al-Maghrib’s annual report on banking supervision (2025 financial year) mentions preparatory work on a national green financial taxonomy. This guide makes no assumption about its content or adoption date: until it is published, the lender chooses its grid.

For a non-financial company, the most common route is not a bond issue, which is reserved for issuers with market access, but a green loan or financing from a development lender. In the latter case the lender’s environmental and social requirements are added to the file: see our comparison of IFC Performance Standards and EBRD requirements and our page on EBRD and IFC ESG requirements.

ISO 14030, European green bond, EU Taxonomy: what is the difference?

ISO 14030 is a voluntary international standard; the European green bond is a designation regulated by EU law; the EU Taxonomy is the classification of sustainable activities on which the European designation relies. A Moroccan issuer can follow ISO 14030 without ever falling under EU law.

Under Article 4 of Regulation (EU) 2023/2631, the proceeds of a European green bond must be allocated in full, before maturity and in line with the taxonomy requirements, to fixed assets, certain capital or operating expenditures, financial assets, or household assets and expenditures; Article 5 opens the 15% flexibility shown in the table. For a Moroccan supplier, the EU Taxonomy mostly shows up in questionnaires from European customers and banks: see our page on CSRD, VSME and ESG questionnaires.

How do you prepare a green financing file?

Start from the project, not the label: a useful, costed and measurable project qualifies easily; a vague project does not become green because it is described that way. The file comes together faster when the carbon footprint and site data already exist.

1. Choose the reference framework. Ask the lender or arranger which grid applies: ISO 14030, the AMMC guide, the EU Taxonomy, a development lender’s requirements.
2. Qualify the project. Link each expenditure to an eligibility category and exclude those that do not fit.
3. Measure the baseline. Impacts are calculated as a difference: without a measured baseline, no impact can be demonstrated.
4. Organise traceability of proceeds. A dedicated account or allocation register, reviewed by management control.
5. Write the monitoring and reporting plan. Indicators, method, frequency, owner, format.
6. Prepare for verification. An organised evidence file for the independent body you choose.

Before submitting the file, run through this list:

• The eligibility reference (ISO 14030-3, EU Taxonomy or other) is known and accepted by the lender or investors.
  
• Each financed expenditure is linked to an eligible category, with its justification.
  
• Impact indicators are defined before financing, with their calculation method.
  
• The baseline of each indicator is measured and documented.
  
• A register tracks the allocation of proceeds and what happens to unspent amounts.
  
• The format and frequency of reporting to investors or the bank are set.
  
• The company’s carbon footprint is up to date and consistent with the impacts announced.
  
• The verification body is identified and independent from whoever prepared the file.
  
• Commitments made in the file appear in the investment plan and in risk management.
  

Consistency with your other disclosures. Impacts announced in a green financing report will be compared with your carbon footprint, your ESG report and, if you report under IFRS S2, your climate metrics. The structure is set out in our IFRS S2 requirements guide. A figure that differs from one document to the next is the first thing a verifier or analyst will spot.
