At Cassiobury Infant & Nursery School, we are dedicated to fostering a sustainable future, fully aligning our efforts with the government’s sustainability and climate change strategies. We strive to reduce our carbon footprint, which is an integral aspect of our School Development Plan (SDP).

To actively promote sustainability, we have established a student eco-council that empowers our pupils to engage in eco-friendly initiatives. Our efforts are guided by a nominated sustainability lead and a focused working party that includes our Headteacher, School Business Manager, and several governors.

Our school has collaborated with a Climate Action Advisor who conducted an audit covering four key areas and produced a detailed report. This document outlines our current initiatives and provides valuable recommendations for further development and improvement; it has also been used to guide our Climate Action Plan.

Our comprehensive Climate Action Plan addresses the four key areas of:

1. Decarbonisation

2. Adaptation & Resilience,

3. Biodiversity

4. Climate Education & Green Careers.

Through these initiatives, we aim to cultivate a culture of sustainability within our school community, inspiring students to be responsible stewards of the environment. Together, we are making significant strides towards a greener future.

The Eco-Schools Awards

The Eco-Schools programme unites young people to make realistic but dynamic change, creating positive impacts for our planet right now. The Eco Council follows a simple, seven-step framework that empowers young people to make a difference in their school, local community and beyond. Schools connect their activities to three or more of the Ten Eco-Schools Topics. These topics break large, global issues like climate change into more manageable and directed themes that prompt young people to consider environmental changes that they can make in their school and everyday lives.

The Eco-Schools Green Flag is an internationally recognised award for excellence in environmental action and learning. In July 2025 Cassiobury Infant & Nursery School achieved it’s third Green Flag award with Distinction.

The Eco-School Committee

Our Eco Council is made up of 18 members. The committee meet at least once a month and include children from Reception to Year 2. At committee meetings we discuss the school Eco Action plan and collaboratively work towards achieving the targets. Eco members take pride in the work that they do and feed back to the rest of their class the key points of discussion after each Eco Council meeting; sometimes they talk in assembly about projects that they are working on.

Environmental Review Autumn 2025

The Eco Council carried out an environmental review to identify areas of strength and points for development linked to the ten topics. We answered all the questions and then added up our score. This information helped us to see what we are already achieving, and what we can do better; you can read our review below

Eco-Code

The members of the Eco-Council came up with their own Eco-Code which we have copied and placed around school. It’s purpose is to support the children and adults in school to remember key actions they can undertake to help work together to look after the environment.
