The Institute for Sustainable Infrastructure (ISI) offers membership to organizations, from both the public and private sector. Individuals may become credentialed to demonstrate their expertise in sustainable infrastructure. As of June 2016, more than 4,500 professionals and students from 20 countries had obtained the ENV SP credential and 13 projects had been awarded an Envision rating. 20% of credentialed professionals work for federal, state and local government agencies.
The APWA Emerging Leaders Academy Class V (2012) report included several documents, shown below, which may help agencies join their colleagues in transforming the way public works infrastructure is developed, operated and maintained.
