Reduce Greenhouse Gas Emissions
WHY: To mitigate the worsening of climate change we must facilitate the reduction of energy consumption from our buildings, encouraging renewable energy, and helping the switch to sustainable transportation.
HOW: Facilitate the reduction of energy consumption in the built environment and the switch to sustainable transportation. eCommuter Fest, Sustainable Home Expo, and Green House Tours are a few examples of how we engage the community.
Princeton’s Climate Action Plan
Princeton’s Climate Action Plan (CAP) provides an ambitious, community-based path to reduce emissions
- 50% (from 2010 levels) by 2030
- 65% by 2040
- 80% by 2050

Princeton’s Greenhouse Gas Inventory
Princeton’s largest source of GHG emissions comes from our built environments, meaning our homes and businesses. Our second largest source of GHG emissions is from our transportation section. We chose to focus our efforts mainly on those sectors of the GHG inventory as waste represents only a small portion of our Scope 1 emissions, making it less impactful in our overall strategy.
Seeing the emissions in the Production-Based GHG inventory can be intimidating but luckily there are a number of ways we can reduce the emissions in both sectors.
OUR INITIATIVES
Our initiatives aim to drive Greenhouse Gas reduction by promoting energy and money-saving programs, engaging the community in events, and highlighting those who are doing the work.

The Municipality of Princeton has a goal to reduce carbon emissions and to help the community become more resilient. An easy way for residents to get involved is by participating in one of PSE&G’s energy-efficiency programs.
Community solar projects are large, central solar arrays that generate electricity. They provide the benefits of solar to those who are not able to install rooftop solar. Subscribe to a project!
eCommuter Fest

Sustainable Princeton has hosted eCommuter Fest since 2020. This annual event celebrates low-carbon and carbon-free commuter options with the Princeton community and includes educational tables, E-bike test rides, an EV showcase, and more!
Sustainable Home Expo

The Sustainable Home Expo allows residents to speak directly with sustainable contractors, landscapers, and solar installers. Along with the expo floor, there are educational sessions on a variety of sustainable home topics.
Green House Tour

The Green House Tour is held in partnership with the Princeton Environmental Commission. Attendees can see how neighbors create healthier and more energy-efficient homes and environments with green building practices, such as solar panels with energy storage, rain gardens, superior insulation, and more.
A monthly blog series that showcases individuals, couples, or families for their efforts to emPOWER Princeton through all things energy.
