Philadelphia Environmental Rules: Climate Emergency Mobilization Rules (2026)

Council Resolution 190620 declared a climate emergency in December 2019, calling for citywide carbon neutrality by 2050 and an interim 50 percent reduction by 2030 from 2006 levels. The Office of Sustainability, established by Executive Order 1-21, leads implementation through Greenworks Philadelphia, the Municipal Energy Master Plan, and the 2021 Climate Action Playbook. Building Energy Performance Policy (Philadelphia Code 9-3402) requires existing commercial and multifamily buildings over 50,000 square feet to benchmark and tune up. The 2030 District and Solarize Philly programs accelerate compliance. Departments must report greenhouse-gas inventories and align procurement to the playbook. The resolution itself is non-binding, but companion ordinances impose actual reporting and retrofit duties.
