BOSTON – As the president marks 100 days in office, opponents of Trump's policies on climate change and green-energy jobs plan to rally on Boston Common and across the nation this weekend. 

Nathaniel Meyer is the Boston-based associate climate campaign director for Corporate Accountability International. He'll be among those at the rally, which he says will include those most negatively impacted by President Trump's cabinet appointments and energy policies.

"It's across the board, both the people that he has picked and what he's done; his national budget proposal disbanded the Clean Power Plan," he said. "So, he's defunding everything that moves us forward on climate, and putting the folks who got us into this crisis in charge."

The rally begins at noon on Saturday at Boston Common. Hundreds of thousands are expected to take part in similar actions this weekend, including the People's Climate March in the nation's capital. 

Maria Belen Power, associate executive director of the group Grass Roots in Chelsea, says Saturday's action also aims to keep the pressure on for more good-paying jobs in the green-power sector.

"As we transition, which we are, into a fossil-fuel-free economy, that we have good protections for workers, and that this transition helps low-income communities lift up and get out of poverty," she said. 

Power says her group also will be taking part in the national People's Climate March on Saturday.

"We are sending a full bus from Chelsea, mainly young people of color; and we want to make sure that our faces and our communities are being represented in this nationwide march and demonstration in D.C.," she explained.

The People's Climate March kicks off at 11 A.M. on Saturday in Washington, D.C.
