Bloomberg has launched the US Municipal Impact Index designed to track municipal bonds categorized as green, social, and sustainability.

The index tracks around 2800 securities and is the first standardized measure of the US municipal tax-exempt investment grade impact bond market.

The index is derived from Bloomberg Index Services Municipal Index and applies Bloomberg’s data and its municipal data analysts’ research to categorize as Green, Social or Sustainability municipal bonds on the Bloomberg Terminal. For inclusion in the index, a bond must either be self-labeled as Green, Social or Sustainability directly from an initial offering, reviewed by independent assurance providers, or use 100% of proceeds for a project in line with the International Capital Market Association Principles.
