Can Mayor Michelle Wu make downtown Boston a hub for climate-tech?

Maybe her administration’s efforts can get a jolt from the state’s big economic development bill, which, if passed this week on Beacon Hill, would pump hundreds of millions of dollars into the sector. Or maybe they get a boost from a big party on City Hall Plaza to showcase local climate-tech companies — like the one Wu hosted last week with help from global energy company Schneider Electric, the Downtown Boston Business Improvement District, the Northeast Clean Energy Council, and the Massachusetts Clean Energy Center.

A few dozen companies with local ties set up booths for the day on City Hall Plaza. Some were from Boston but many came from outlying communities. Among those from the neighborhood: EnergySage, whose offices overlook the plaza from across Cambridge Street, and Schneider, whose North American headquarters office is a short walk away, off Washington Street. (Coincidentally, downtown won another climate-tech business two days later when car-charger supplier EVPassport announced it would open its East Coast headquarters in the Financial District.)

Outside City Hall, Wu was joined by Schneider executive Bryan Stevens, state economic development secretary Yvonne Hao, and NECEC president Joe Curtatone, the former longtime mayor of Somerville.

Curtatone injected some hyperbole when he introduced Wu to the crowd, forcefully referring to her as “the national and global leader on forging a new equitable economy.”

Once it was her turn to speak, Wu couldn’t help but admit that “it’s always great being introduced by a former mayor.”
