The City of Somerville might be onto something here; it is efforting to become carbon neutral by 2050. If all things are equal or at least close to equal, I believe local small-to-mid-sized companies would embrace the green initiative. The challenge only really exists when being green adds measurable cost to the companies monthly overhead.
From the BBJ:
“‘Sustainability and taking care of the environment is a deeply held conviction of the community,’ said Daniel DeMaina, media manager for the city of Somerville, in an interview…The city will release a form called a Request for Information, for companies to propose their green-tech ideas at an event on Oct. 21. Companies have until Dec. 1 to submit their plans.”
