Environmental Finance’s database tracks every self-labelled green, social and sustainability bond issued since the inception of the market in 2007.

We include bonds where the issuer and/or lead manager explicitly states that they are green, social or sustainability-focused. This includes:

  • Corporate self-labelled bonds
  • Green Asset Backed Securities; asset-backed securities whose cash flows come from a portfolio of underlying receivables such as loans, leases and PPAs. The receivables are associated with green (e.g., renewable energy, energy efficiency) projects.
  • Green Mortgage Backed Securities
  • Green Project Bonds; bonds backed by the cash flows of an underlying renewable energy project or portfolio of projects
  • Green, Social and Sustainability Sovereign and Supranational Bonds; bonds issued by multilateral banks, development finance institutions and export credit agencies to finance green projects. This includes bonds issued by national development banks
  • State and Municipal Bonds; bonds issued by state, municipal and provincial (i.e., subsovereign public sector) entities to finance green projects
  • Green Guarantees; bonds issued by OPIC included

The majority of these bonds are aligned with one of;

  • The Green Bond Principles
  • The Social Bond Principles
  • The Sustainability Bond Guidelines
  • Climate Bonds Certification, issued by the Climate Bonds Standard Board
  • Green Financial Bond Directive, issued by the People’s Bank of China
  • Green Bond-Endorsed Project Catalogue, issued by the People’s Bank of China

Private placements – we include private placements where these have been declared to us and we have sufficient information to include in the database.

* Environmental Finance has decided not to opine on what is or isn’t green, social or sustainable, and will include any bond that has been self-labelled as such, with the intention of creating a comprehensive database where professional users can make their own judgements, based on their knowledge and supporting documents available on the database.

Research Method

Environmental Finance has a reputation in delivering market-leading content on the green bond market. Since the launch of this market in 2007 Environmental Finance has built a respect in the market for honest and unbiased reporting based on the facts. Accuracy is important to us and with many issuers and investors sharing information with us this enables us to provide you with premium content.

Documentation and official statements are gathered by contacting issuers or lead managers involved in the issuance, through emails or phone calls. In addition, our analysts conduct web research of the issuers web sites to extract relevant information. The bulk of our data is drawn from research.

We will include any loans where the borrower or lender states that they are green or sustainability-linked. Initially, at least, many of the loans in the database will not explicitly align with the Green Loan Principles or the Sustainability-Linked Loan Principles, as these voluntary guidelines have only recently emerged.

As in the bond section of the database, Environmental Finance will not opine on what is green or sustainability-linked and will include any loan that has been self-labelled as such. Our aim is to create a comprehensive database to enable professional users to make their own judgements about the environmental or sustainability credentials of the deals.

The loans section will also follow the same conventions used for bonds in allocating an equal share of multi-lender loans to each lender, unless we have evidence that certain lenders contributed more than others.
