Sustainable Princeton announced a changing of the guard for board president and the addition of two new Board members. Co-Founder and Board President, Matthew Wasserman is passing the leadership baton on to Vice President, Yamile Slebi.

“Eight years ago, a small group of people committed to the idea of changing people’s habits and getting ‘sustainability’ a seat at the table, got the ball rolling by starting a small non-profit with local grant money,” recalls Wasserman. “We knew it wouldn’t be easy, but then again, when are the things really worth doing, easy? As board president, I have been honored and fortunate to be surrounded by incredibly smart, passionate people as we have worked to build Sustainable Princeton into what it is today.”

On passing the baton, Wasserman reflected, “We have earned that seat at the table as evidenced by the recent endorsement of the Climate Action Plan and the assignment of a council liaison to our Board of Directors. While I admit I’m a bit sad about stepping down at such a crucial juncture, I know our new Executive Committee, led by Yamile, is immensely qualified to lead us into the future. I look forward to seeing what they accomplish. And like any proud parent, I know they’ll do great things.”

A corporate and securities lawyer, Colombia native Yamile Slebi began her support of organizations in the nonprofit sector at FairTrade USA where she worked with farmers around the world on market access, quality improvement, and capacity building. Prior to joining the Sustainable Princeton board in 2015, she volunteered working to help with the Great Ideas initiative, now in its 7th year.

“I’m very proud of the organization Sustainable Princeton has become. We have an amazing staff and a very committed board,” said Slebi. “One of the strengths of our programming and community outreach is presenting residents with sustainable choices that protect the environment and generate financial savings. Home energy audits, for example, can translate into residents saving on energy bills and a reduction of the collective impact on our footprint right here in Princeton.”

Princeton’s Climate Action Plan (CAP) was endorsed by Municipal Council last July. Since then, Sustainable Princeton has worked with multiple stakeholders and committees to implement strategies outlined in the plan.

Slebi continued, “with the CAP, we are hoping to reduce Princeton’s greenhouse gas emissions and build the community’s resiliency, (the ability to withstand the effects of climate change). This aspect is very close to my heart,” shared Slebi, “it has the potential to directly benefit Princeton’s underserved population. We are currently working with the municipality on the creation of Princeton Prepares, a new registration program to assist our most vulnerable residents during climate crises.”

Slebi especially enjoys working with students on green projects because they are passionate about protecting our planet — “the younger generations get it,” she says.

“Every town should have an organization that leads the community to take action for a healthier local ecosystem, emissions reductions, and resiliency. We are so fortunate to have Sustainable Princeton working on these critical challenges and I am sincerely honored to support the organization by helping to lead the charge,” said Slebi.

Of this, Sustainable Princeton Executive Director, Molly Jones, said, “Sustainable Princeton is extremely fortunate to benefit from the skills and expertise of a top-notch Board. The addition of Steve Averbuch and David Hill will further strengthen our joint efforts. Matt has done an incredible job supporting the organization’s evolution, so it is bittersweet to see him shift from the role of President. Yet, we are excited by the fresh view and thinking that Yamile will bring to this position and to helping Sustainable Princeton realize its full potential.”
