Institute for Sustainability (IfS)

IfS is an umbrella organization encompassing a broad spectrum of activities related to sustainability. It has three sub-entities: the Sustainable Engineering Forum (SEF), the Center for Sustainable Technology Practices (CSTP), and the Youth Council on Sustainability Science and Technology (YCOSST). It also provides oversight to the AIChE Sustainability Index (sm).

Environmental Division (ENV)

The ENV division provides relevant programs on current environmental topics and non-confidential information concerning all aspects of environmental activity. The division promotes publication of papers of interest to chemical engineers in environmental activities as well as coordinates the Institute’s activities with other related societies.
