Cambridge Zero Carbon began in 2007 as a group of students, scientists, economists, and professionals who were deeply concerned about the climate crisis.
The group has been one of the most active organising groups in recent Cambridge history – coordinating over 30 direct actions and penning 6 public reports between 2015-2020.
The peak of their activity occurred in 2018 and 2019 around successive votes for divestment at University Council.
After five years of campaigning, Zero Carbon celebrated a “historic victory” in October 2020 when the University finally committed to fully divest by 2030.
After the launch of the University’s own “Cambridge Zero” initiative, Zero Carbon changed its name to Cambridge Climate Justice, and remains in operation.
In recent years, the University is still attracting criticism for delays, having “no plan” for actioning divestment, and continuing to accept fossil fuel donations.
