Verify - EPA's Engine and Vehicle
Compliance Information System
What is Verify?
Verify is an innovative information management system that centralizes emission-related
and fuel economy data for all transportation and other mobile source industries. The U.S.
Environmental Protection Agency (EPA) uses the data located in this system to determine
a manufacturer's compliance with engine and vehicle emission standards as well as fuel
economy standards. As a state-of-the-art, integrated computer system, Verify consoli-
dates and replaces several smaller systems, including the Certification and Fuel Economy
Information System (CFEIS) and the Information Management System (IMS), while also
incorporating newly-regulated industries that have no prior compliance information system.
The Verify system facilitates the collection of manufacturers' data which streamlines EPA's
review, approval and distribution of certification and fuel economy information. In addi-
tion, Verity's reporting capability provides the data for the Agency's public information
web sites, such as EPA's Green Vehicle Guide and the Document Index System, as well
as the Fuel Economy Guide (a joint EPA/Department of Energy Web Site).
