The Climate Bonds Standard is a screening tool for investors and governments which allows them to easily prioritize climate and green bonds with confidence that the funds are being used to deliver climate change solutions.

Why is a Climate Bond Standard needed?

Investor demand for Green Bonds & Climate Bonds is strong, and will increase in line with the delivery of quality products into the market. However, investor concerns on the credibility of Green labelling are also growing. Standards, assurance & certification have been identified as key to improved confidence and transparency, and further strong growth.

Moreover, without broadly acceptable standards we will have a race to the bottom with environmental-themed bonds.  We have already seen a weakening of carbon offsets because of a lack of standards about acceptable (environmentally rigorous) schemes. Poor quality offsets were, for many buyers, not readily distinguishable from high quality offsets. In such circumstances poorer quality offsets dominated for price or availability reasons, sparking a race to the bottom, or an abandoning of the sector.

Early intervention is needed to avoid the negative effects of a lack of robust standards and a consequent undermining of the credibility of the thematic approach.

Won’t the market sort this out eventually?

Standards may emerge after a number of years; but we don’t have time to allow that to happen organically. We need to quickly channel funds where they need to go.

Markets don’t develop standards spontaneously. But standards imposed by appropriate agencies can promote the growth of markets.

How does it work?

The Climate Bonds Taxonomy is the first piece of the Climate Bond Standards and Certification jigsaw. It is a public good that can be used by issuers to assess whether they have green assets, prior to issuing a green bond. It identifies broad areas of inclusion (e.g. green residential mortgages, low emissions vehicles etc) that are subject to further criteria and screening.

The Climate Bonds Standards builds on the Taxonomy and set out specific criteria so green bond issuers can assess the environmental integrity of bonds claiming to address climate change mitigation and adaptation.

Finally, in order to receive the “Climate Bond Certified” stamp of approval a prospective issuer of a Climate Bond must appoint an approved 3rd party verifier, who will supply a verification statement that the bond meet the Climate Bond Standard’s environmental and financial guidelines. The Climate Bonds Standards Advisory Board* (comprised of members representing $34 trillion of assets under management) provide the final confirmation.

There are three phases of the Certification process.

  1. Pre-Issuance Certification:  Assessment and certification of the bond issuer’s internal processes, including its selection process for projects & assets, internal tracking of proceeds, and the allocation system for funds. Reasonable Assurance from the Verifier is required for fist-time issuers. 
  2. Agreed-Upon-Procedures Review available for previous issuers of Certified Climate Bonds and covers the Pre-Issuance Requirements but uses a simple checklist-style approach to assess the issuer’s conformance
  3. Post-Issuance Certification: Assessment and certification of the bond, which must be undertaken after the allocation process is underway, and includes reasonable assurance from the verifier that the issuer and the bond conform with all of the Post-Issuance Requirements in the Climate Bond Standard

Isn’t a renewable bond obviously green?

Some projects clearly are associated with reductions in carbon emissions — such as solar and wind power projects. Some are important but must be managed carefully, such as biofuel and bioenergy projects involving land use changes. Some are controversial, such as carbon capture and storage.

The benefit of a standard is that it allows investors to assemble diverse portfolios with confidence about the investor acceptance of their environmental integrity.

How will the standard assessment work for the bond? Will it be a yes/no decision?

The standard will assess the low-carbon value of the bond’s underlying assets.

Projects such as solar and wind can be expected to have a simple yes/no decision-making model. Project types that require more complex evaluation, such as energy efficiency, may have conditional certifications.

Are there fees involved?

Yes, Climate Bonds issuers will pay a small fee for verification of their claims (to be determined by the verifier) and then for certification. Registration of the bond with the Climate Bonds Standard Advisory Board* = one tenth of a basis point. E.g. £5,000 on a £500 million bond

Why would bond issuers bother?

Four reasons:

  1. Diversify investment base – certification signals the low-carbon integrity of the bond and is important for investors looking for climate related investments
  2. Easy-find: it allows potential investors to quickly find your bond on Bloomberg and on other listings. Additionally, the Climate Bonds Initiative circulates your offering to every investor on its stakeholder list.
  3. Reputation: associate organisation with efforts to scale up financial flows for delivering the low-carbon economy and securing prosperity for future generations.
  4. Cost: remove cost to investor of environmental due diligence.

What is innovative about the standard is that it allows not only obvious project bonds for renewable energy generation or green portfolio bonds to be labelled as ‘climate bonds’, but it also allows corporate bonds to be linked with low-carbon activities, without compromising on the normal credit ratings of the issuer.

An authoritative standard eases decision-making and focuses attention on credible climate change solution opportunities. The easier it is to use the faster the market will grow.

How can we be sure of the independence of the Climate Bond Standard Program?

The Climate Bond Standards Advisory Board* oversees the development of the Program. Membership of the Board will be comprised of environmental non-government organizations (ENGOs), asset-owners such as pension funds, government officials, and quasi-government institutions such as multi-national development banks.

Members include California State Treasurer John Chiang, the Natural Resources Defense Council, the Investor Group on Climate Change and the Carbon Disclosure Project.

The standard development process allows for a broad and transparent stakeholder consultation period, where interested parties will provide input and comment.

Who is behind this Program?

The Standard Program has been initiated by the Climate Bonds Initiative (CBI), an investor-focused not-for-profit organization promoting large-scale investment in low-carbon industries. More information can be found at The CBI staff the Program.

The Board is supported by “industry working group”. Members of that group include representatives from the International Finance Corporation (IFC) Standard & Poor’s, KPMG, Calvert Funds Management, DNV and Environmental Capital Management.

Funding for the development of the Program comes for a range of sponsors, including foundations and corporations.

Will oil and gas companies be allowed to issue climate bonds?

The standard will assess the low carbon value of the bond as it relates to the intentions of the issuer and the assets linked to the bond.

Oil companies re-financing and/or investing in low carbon assets applicable under the standard, such as wind energy, would be eligible.

What will monitoring requirements be?

The monitoring requirements for compliance with the standard depends on particular project types with little or no monitoring for straightforward areas such as renewable energy and annual and/or more complicated monitoring requirements for other projects.

Will the standard affect creditworthiness of a project?

The Climate Bond Standard is not a financial standard or a substitute for financial due diligence procedures.

Over time, certification of environmental credibility may improve the attractiveness of projects and increase demand. But creditworthiness will need to be assessed in the usual manner.

Will certification apply to just one bond or is it an agreement that will operate for all bonds by a particular Issuer going forward?

Each Climate Bond would be covered by a separate agreement in much the same way as a Credit Agency rating is typically given on a deal by deal basis for each bond issue.

How does the Standard work with carbon markets?

We see carbon markets as complementary. They can provide an additional cash flow for underlying projects that bonds are issued against.

However, bonds do not have to prove additionality or estimates of emission reductions to be certifiable. Our approach instead is to develop specific criteria as to what characterizes suitable assets for the Low-Carbon Economy and that bonds raise finance or re-finance these solutions.

How can the Standard work within an international agreement under the UNFCCC?

In theory, the Standard could be used as tool to track private sector finance flows to developing countries to support the implementation of NAMA plans. We are also pressing for the Green Climate Fund to be used a guarantee pool to leverage pension fund money into climate change solutions – much of that through bonds, best-suited to pension fund liabilities that could be certified as Climate Bonds.

How is the Standards project funded?

The Standard and various components will eventually be fully financed by certification fees, but these have been set very low (one tenth of a basis point) so there will first need to be a volume market. The initial development process for eligibility criteria relies on sponsorship and grants at the moment – from National Australia Bank, Bank of America Merrill Lynch Foundation, European Climate Foundation and the Sainsbury Family Charitable Trusts.

The idea of the Standard is to create binary eligibility criteria so as to minimise certification cost; but originators will still need to commission an assurance report from an approved verifier (the first two are DNV and KPMG). That looks to cost $20-50,000 for corporate bonds, possibly less for project bonds. But costs for 50m and 500m are likely to be much the same.

Do Certified Climate Bonds have to be secured?

No. The aim of the the Climate Bond Standard is to support corporate issuance in public markets in the simplest way possible (i.e. using existing documentation. The Standard looks for a clear and traceable relationship between the funds and the assets to which they are linked.

If we have a book of potential projects over the next 12 months, can we work with the verifiers to identify the best projects to assign the funds too?

Yes. The question will be whether they fit the stated eligibility criteria; the verifier’s job is to check that nominated projects comply with the published criteria.
