Redfin data scientists analyzed all properties sold under Redfin in 2015 to find the top 10 greenest neighborhoods across the nation. Two Greater Boston neighborhoods, Newton and Dedham, made it to the top 10.

The term “going green” shouldn’t be new to any industry. It certainly isn’t for home developers. Today, home developers and architects are including more ec0-friendly amenities into their designs and houses. As for the two Massachusetts neighborhoods, they did more than just including “green” amenities into their community.

Newton Centre

At No. 4, Newton has 49 percent of its homes considered green. Instead of building more eco-friendly homes or updating old amenities, Newton provides sustainable resources to its residents. Green Newton, a non-profit organization, provides free home solar evaluations, preferred solar panel pricing and financing options to encourage residents to install solar panels.

There is also a free energy assessment (Newton Energy $avers initiative) and energy efficiency programs (Solarize Massachusetts and Mass Save) that are offered to the residents. Through those initiatives, residents can figure out how to save energy at home. Since 2008, more than 2,600 Newton homes were able to reduce the total carbon emission by 2,000 tons, and save an estimated $760,000 annually.

Dedham

Just beating No. 10 (Del Sur, San Diego), 41 percent of downtown Dedham’s homes are green. Located just 30 minutes outside of Boston, Dedham has such projects as the Sustainable Dedham Initiative, which focuses on educating residents about sustainability, energy conservation, pollution and climate change issues.
