What We Do
DfE Climate Action Plan
The DfE Climate Action Plan (CAP) helps schools and multi-academy trusts measure, manage and reduce their environmental impact in line with the Department for Education’s Sustainability and Climate Change Strategy. Our Climate Action Plan for Schools provides a structured, practical framework to understand where emissions come from, set achievable targets, and implement improvements across energy, travel, waste and procurement.
We co-developed the national Climate Action Plan platform (climateactionplan.org.uk) which is now featured on the Government’s own Sustainability Support for Education site. Through this collaboration, every school can access a free version of the tool, while our premium package adds tailored data, analysis and long-term expert support.
