A number of senators and representatives led by Sen. Chris Murphy (D-Conn.) and Rep. Elizabeth Esty (D-Conn.) have cosponsored The Green Bank Act of 2017 (PDF) (S. 1406. H.R. 2995). The act is expected to support the establishment of a national green bank capitalized with $10 billion in treasury-issued green bonds. This is the third time legislators have proposed it.
