LESS CO2 Schools

Worried about ever increasing energy bills in your school?

Want to become a more eco-friendly, sustainable school but not sure where to start.

Then LESS CO2 is the programme for you!

LESS CO2 focuses on energy and carbon savings, making our schools more sustainable through simple behavioural changes and retrofits.

LESS CO2 links schools together into a geographically close ‘cluster’. Each cluster brings together teaching staff, bursars, site teams and school managers for a year-long energy saving programme. This includes: workshops covering energy saving tips; recording and analysing meter data; behaviour change for staff and students; and incorporating energy-related sustainability issues into the curriculum.

The sessions are led by experienced LESS CO2 mentors, who have helped hundreds of schools on their sustainable journeys.
We know that schools learn best from hearing the experiences of other schools – this is the key to the success of LESS CO2.

As well as saving energy and money, LESS CO2 helps students take more responsibility in the running of their school and makes both staff and students more aware of the impact they have, through the use of energy, on the environment.

How to get involved

Information for maintained schools

As an individual school there are a number of options to being part of the LESS CO2 programme. This may depend on whether an existing cluster is active in your area, or, if not, whether you can start your own cluster with other neighbouring schools.

Information for Academy Trusts schools

We can set up a bespoke cluster exclusively for the schools within the Trust. Register your interest below and we will get in touch to discuss your specific requirements.
