A free-to-use online resource – specifically designed for school sustainability champions.


Join a growing movement of schools taking action to reduce their environmental impact. The Greener Schools Index is a powerful, free-to-use online resource designed to help schools measure, track, and benchmark their sustainability progress.
Developed in partnership with the UK Schools Sustainability Network (UKSSN) Operations Group, this initiative provides essential insights across key sustainability areas, including energy, air quality, biodiversity, waste management, and more.
The Greener Schools Index invites schools to complete a comprehensive online survey, developed alongside esteemed sustainability authorities Paul Edmond, Chief Finance and Sustainability Officer at HEART Academies Trust, and Helen Burge, Consultant Consultant School Business Leader.

Our second Greener Schools Index report draws on data from schools and Trusts, revealing that while sustainability is a growing priority, it remains an aspiration for many settings.
In this report, we highlight the key findings, including the role of the GSI in shaping Climate Action Plans. We explore where schools are making meaningful progress and where there is more to do, alongside insight from a school leader who has used the GSI to drive their sustainability journey.
Discover how they used the GSI as a baseline to create a structured roadmap, identify next steps, and track progress over the course of a year.
Getting started is simple and rewarding. By following a few easy steps, your school can gain a clearer picture of its sustainability journey and uncover new opportunities for improvement.

The Greener Schools Index is more than just a survey- it’s a movement driving real change. Zenergi’s first national report is out now, using data insights to highlight areas where schools need more support. Your participation in the next one can help influence policy and secure funding for sustainability initiatives in education.
The report reveals that while many schools have now appointed sustainability leads, fewer have formalised a Climate Action Plan, and 53% are still actively working towards integrating sustainability into their broader development strategies.
