The California Green Building Standards Code—Part 11, Title 24, California Code of Regulations—known as CALGreen, is the first-in-the-nation mandatory green building standards code. In 2007, CBSC developed green building standards in an effort to meet the goals of California’s landmark initiative AB 32, which established a comprehensive program of cost-effective reductions of greenhouse gases (GHG) to 1990 levels by 2020.
CBSC has the authority to propose CALGreen standards for nonresidential structures that include new buildings or portions of new buildings, additions and alterations, and all occupancies where no other state agency has the authority to adopt green building standards applicable to those occupancies.

In partnership with the California Building Officials (CALBO), the International Code Council (ICC) offers a CALGreen Certification Exam that is intended to validate the competency of inspectors and plan reviewers on their understanding and ability to implement the provisions of CALGreen. The CALGreen Inspector/Plans Examiner certification exam covers such topics as general requirements of CALGreen, residential building systems, and non-residential building systems. The certification is offered via computer-based testing.
