5 Los Angeles, CA Federal Movement to Zero: By 2030 each GSA regional operating division should verify at least 50% of their building area to be NZE, and should continue planning additional NZE projects.

6 Benchmarking & Disclosure

7 Regional Movements

8 CA Movement to Zero

Leading by Example California s Policy for Public Buildings Executive Order B 18 12: state

New or major renovation of State buildings larger than 10,000 square feet use clean, and clean

100% of new State buildings & major renovations beginning design after 2025 to be ZNE
