More than 30 students and organizers staged a sit-in at a Tufts University administration building Tuesday morning to demand a meeting with the school’s brass about fossil fuel divestment.

Tufts sophomore Shana Gallagher said the students plan to try to peacefully occupy Ballou Hall until Tufts commits to divest its endowment from fossil fuel companies over a five year period.

The sit-in coincided with Earth Day. Recently, students from universities across the country – including Harvard and Yale – have pushed for their schools to divest from fossil fuels.

Most of the students were from Tufts Climate Action.

In a statement, that group said, “the climate crisis is an imminent danger to mostly low-income communities and communities of color across the world, and Tufts simply cannot continue to invest in and profit from this destruction.”

The group said by investing in fossil fuel companies, the Medford-based university is ignoring climate change and “refusing to live up to its own core values.”
