"The city of Boston on Tuesday launches Carbon Free Boston, which officials describe as the city's next step to becoming carbon neutral by 2050.
The initiative aims to address how to fuel a growing Boston while also meeting the city's climate goals.
There are currently 106 buildings, worth $9 billion, under construction in Boston. Over the past five years, the city has approved adding the square footage equal to 45 new Prudential Towers.
"We're very fortunate right now," said Austin Blackmon, the city's chief of energy, environment and open space. "Boston is in one of its largest building booms in its history, and that means there are great opportunities for us to have a lasting impact on the future of our city.
Boston already has more LEED-certified energy efficient buildings than any other city in the nation. And Massachusetts has been named the most energy efficient state seven years in a row.
By 2050 the state is committed to reducing emissions from fossil fuels by 80 percent. Boston is even more ambitious: It wants to be carbon neutral by then."
