Our Methodology

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.
