A Greener King's

The College's efforts to improve environmental sustainability began, like many things at King’s, as a spontaneous grassroots movement amongst students, staff, and Fellows alike. In 2009 this passion and commitment led to the College implementing an Environmental Policy, which asserted its commitment to acting sustainably at every level of its institutional operations. In recent years we have seen sustained reductions in our energy use, with insulation improved, inefficient boilers replaced, and new buildings constructed to efficient Passivhaus standards. In order to reduce our carbon emissions, we have adopted a decarbonisation strategy, based on an initial report, with the aim of becoming carbon net-zero by 2038. A second decarbonisation report has recently been commissioned to more accurately assess the carbon emissions across all the College's buildings and operations.

Building for the Future

Sustainable construction methods and advances in technology are offering new possibilities to minimise the carbon footprint of our buildings.

Wildflower Meadow

Since 2020 the College’s Back Lawn has been converted into a colourful wildflower meadow stretching from the Chapel to the Cam.

Sustainable Planting

King's has undertaken a wide variety of initiatives to promote biodiversity and tackle the nationwide decline of pollinators. 


The College has fully divested from all direct investments in fossil fuels and invests positively in environmental markets - but more can be done.

Get Involved

Improving our sustainability is a College-wide effort that necessarily involves all members of the King's community, staff and students alike.

Environmental Research

Academics at King's are helping to address the key challenges of the climate crisis and lessen the impact of pollution and waste.

Renewable Energy

Moving towards renewable energy sources can diminish our reliance on fossil fuels and the untold harm they do.

Global Projects

Tackling the effects of climate change and halting further destruction of habitats requires global collaboration.

Growing Local

Growing our own food can play a big part in preserving our local environment and reducing our carbon footprint.

Helping Ecosystems

Mitigating the destruction of habitats and use of pesticides can help arrest the sharp decline in pollinating insects.
