What is the City of Philadelphia’s Office of Sustainability?

Posted by City of Philadelphia Office of Sustainability on August 12, 2025

The Philadelphia Office of Sustainability (OOS) is one of the many city offices that make up a vast team of public officials under Mayor Cherelle Parker. Run by a team of six people who oversee four divisions, the OOS covers climate sustainability, policy, and solutions for Philadelphia.

The Office of Sustainability (OOS) communicates with and collaborates across several divisions to create a more resilient, climate-prepared, and energy-efficient Philadelphia. This may look like creating a flood resilience strategy with Eastwick residents, or a Municipal Energy Master Plan to reduce energy use and clean the energy supply.

The Climate Resilience Division focuses on supporting community resilience when dealing with increasing climate change-related risks. In Philadelphia, common risks include flooding and extreme heat. The Climate Resilience Division is updating the City’s Climate Resilience Plan by updating climate projections, assessing community vulnerability, and using those projections as guidance for resilience strategies. A public survey is also available in seven different languages to inform the new plan.
