AIChE Credential for Sustainability Professionals

The American Institute of Chemical Engineers (AIChE) Institute for Sustainability is well positioned to establish a baseline definition of what Sustainability entails, as well as to establish a Body of Knowledge (BOK) in the field of sustainability. The body of knowledge at the heart of the new sustainability credential is based on AIChE’s Sustainability Index.

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).
