Winds of change are starting to blow through Boston’s business community.

One clear signal came earlier this month, when close to 20 business organizations said they would heed an appeal from House Speaker Robert DeLeo to help develop a transportation policy that likely will call for additional revenues. "It's time for a united voice from the business community that can be a powerful driver of progress," said Jim Rooney, the CEO of the Greater Boston Chamber of Commerce.

On the issue of climate change – and what to do about it – the folks at the Environmental League of Massachusetts say business community attitudes are also changing on climate change. League officials offered up for the CommonWealth Codcast three business leaders who reflect that change -- Cynthia Curtis, senior vice president of sustainability at the commercial real estate firm JLL; Kyle Cahill, director of corporate responsibility at John Hancock; and Tedd Saunders, chief sustainability officer at the Saunders Hotel Group.

“For a long time, legislators were only hearing from industry representatives and businesses that said this legislation or that policy is going to be bad for business – we’re going to have to lay off people and costs will go up,” said Saunders.
