For a quarter century, Green Decade Newton has been an advocate for environmental action. Now known as Green Newton (GN), the organization will host a 25th Anniversary Celebration from 7 to 9:30 p.m., June 11, at Lasell College. The event honors GN’s work for change in Newton, and its 2015 New England Merit Award from the Environmental Protection Agency for “outstanding contributions on behalf of our region’s environment.”

The same GN board and membership will continue its work advocating for the environment and educating the public about leading a sustainable lifestyle. “We anticipate our new name will enhance the public’s understanding of our purpose, and attract more people and businesses to become involved in Green Newton’s important work for the environment,” says Board President Marcia Cooper.

The anniversary celebration includes live music, hors d’oeuvres, desserts, wine, raffles and a silent auction. Boston Globe columnist Derrick Z. Jackson will speak, and two Newton residents will be honored for their contributions as local environmental leaders.

“We work hard all year to educate folks and preserve our environment, and this is a chance to celebrate our successes over 25 years,” says event Co-Chair Sunwoo Kahng. “This includes the recent EPA award and our new website, and one of our board members, Peter Smith, is making sure we have enough carbon offsets so that our party will be carbon neutral.”
