ISI advances sustainable infrastructure using the Envision sustainability framework, through education, training and third-party project verification.

The Institute for Sustainable Infrastructure is an education and research nonprofit (a 501c3) based in Washington DC. It was established in 2010 by the American Public Works Association (APWA), the American Society of Civil Engineers (ASCE), and the American Council of Engineering Companies (ACEC).

Responding to the need for a comprehensive sustainability framework and rating system suitable for use in civil infrastructure development, ISI collaborated with the then Zofnass Program for Sustainable Infrastructure at the Harvard University Graduate School of Design to develop Envision®.

ISI’s community is growing through project verification and credentialing in many countries and regions, including Italy, Spain, Mexico and Latin America, and China.
