STAR Neighborhoods

The STAR Neighborhoods program gives Princeton residents the opportunity to actively participate in building a more sustainable, together and resilient community.

STAR neighborhoods select activities that will strengthen their community, reduce its carbon footprint, and inspire others to follow suit.

In doing so, neighborhoods earn program credits for their efforts and can achieve designation as a certified STAR Neighborhood for that calendar year.

Getting started.

Three actions are necessary to launch a STAR Neighborhood.

  1. Build a Network: To start, identify your neighbors and build a phone or email list. Read more about how we define a neighborhood.

  2. Pick your Leaders: Identify two or more liaisons for your neighborhood.
  3. Establish Your Goals: What would you like to see done in your neighborhood? Review the list of actions and pick two or three for the coming year. Feel free to invite us to help you brainstorm.

Complete these steps and you are ready to register for the STAR Neighborhood program! Then, make a plan to bring your neighbors together for some fun and community building. Check out these ideas for neighborhood gatherings.

Once your neighborhood has completed the starting actions, you will have already earned 30 points!

To determine how you will get the next 70 or more points, review the STAR Neighborhood Action Items and select one or more actions to pursue over the next year. Please ensure this is a group decision, give special consideration to the priority actions, and consult with Sustainable Princeton to determine the best actions for your neighborhood.

Consider the example in Table 1 for what one neighborhood’s activity in a one-year period might look like. By performing the three starting actions, hosting two well-attended seminars, and implementing one priority action, the neighborhood earned just enough points to have achieved Silver STAR Neighborhoods certification.

Earning Points.

Neighborhoods achieve STAR Neighborhood designation by performing selected actions and documenting their efforts to Sustainable Princeton. Documentation can simply be a photo from the event, a copy of the guest list, or a flyer from the event. STAR Neighborhood program credits are awarded based on the type of activity, as described in Table 2.

Three actions are required to start and each earn 10 points. All other actions should be viewed as potential Outreach, Seminar or Implementation actions, earning anywhere from 10 to 50 points, depending on the type of activity, and in certain cases the number of attendees.

Table 2: Points Awarded for Each Type of Activity

As an example, consider the multiple ways the Home Energy Audit action could be undertaken. As an Outreach activity, a neighborhood could distribute flyers about home energy audits. As a Seminar activity, a neighbor could host a speaker to explain home energy audits. Or as an Implementation activity, some of your neighbors could have home energy audits performed for their home and document the results. In either case, priority status adds 10 points to any one action.

Achieving Certification.

In order to receive certification as a STAR Neighborhood, neighborhoods should record actions and submit them to Sustainable Princeton with documentation. Sustainable Princeton will review all submissions and promptly award points to the neighborhood.

Neighborhoods achieving 100 or more points in a one-year period will be awarded Bronze, Silver, or Gold STAR Neighborhoods certification for that year, as per Table 3.


Each year, certified STAR Neighborhoods will be recognized by the Mayor and Council for their efforts, but perhaps the bigger reward is achieving new sustainability goals and forging new relationships in your neighborhood.

In our rushed and sometimes detached society, neighborhood relationships can be neglected. However, by getting to know your neighbors and learning to trust them, you can support each other during times of need, keep your home and neighborhood more secure, and even improve your health. Furthermore, STAR Neighborhoods have access to information and resources that can actually deliver financial savings.

Currently, all registered STAR Neighborhoods also have access to Mini-Grants that can help fund their activities.

On top of that, every neighborhood should be considered as a fundamental unit of social change. While a person can achieve great things in isolation, we believe the power of a group can do even more!

Renewal in Future Years.

All neighborhoods are encouraged to renew registration for a second year as a STAR Neighborhood. If registration is renewed within a month of the one-year anniversary, any leftover points from the first year will roll over to the next year. For example, if a neighborhood earns 132 points in one year, 100 points are used to achieve the Bronze certification, but 32 points rollover to the next year!

To begin the second year, a neighborhood should update its community emergency network, host another community gathering, and revisit the leadership and goals, before proceeding to select actions.

Nebula Neighborhoods.

Some neighborhoods hit the ground running. They are organized, meet regularly, and have already begun acting to make their community more sustainable. Great! We invite each of these neighborhoods to register as a Nebula Neighborhood, sharing their past actions with us, so that we can share them with the rest of Princeton.

But don’t stop there! Take 10 points and begin your journey as a STAR Neighborhood.

Defining a neighborhood.

By definition, a neighborhood is any residential district that forms a community within Princeton. Neighborhoods can be one block, a street, an apartment building, or even a collection of city blocks. For the STAR Neighborhood program, each neighborhood is welcome to define its own boundaries, based on its unique geographical characteristics.

Types of Neighborhood Gatherings.

To get you started, here are a few ideas to bring your community together.

  • Keep it simple: Host a block party, potluck or backyard bbq.
  • Make it academic: Organize a book exchange or game night.
  • Note your talents: Plan a talent show or karaoke party.
  • Add a twist: Include an international focus or a scavenger hunt
  • Highlight food: Coordinate a cookie swap, wine tasting or soup crawl.
  • Do some good: Organize a charity event or a community yard sale.

Regardless, have fun getting to know your neighbors!
