A key focus for everyone at St John’s is to develop a passion and understanding in our students for the environment.
This passion will lead to our students being at the forefront when making positive change in order to make a difference to the future of our planet. We believe in the principles of ethical responsibility towards the world we live in – a set of principles that sit alongside our educational purpose.

SEA – Schools for Environmental Action was established by St John’s and led by a UN  accredited climate change teacher.

  • We aim to make a significant, positive difference to our environmental impact through raising awareness of practical  actions we can take as individuals and as a school
  • We aim to plan regular activities, such as the whole school Climate Day of action in September 2019
  • We aim to constantly review our sustainability policy to ensure it leads to changes in the daily lives of staff and students in order to help the environment


UN Climate Change Accreditation

The UN, in conjunction with eduCCate Global, wish for all schools worldwide to have tackling Climate Change as a vital part of their vision and curriculum. As part of this they have put together an online course which is free and available for all teachers to become UN accredited Climate Change teachers. The course look at 5 major aspects of Climate Change, including:
Children and Climate Change, Cities and Climate Change, Gender and Climate Change, Human Health and Climate Change, and Climate Change International Legal Regime.

St John’s currently has one UN accredited Climate Change teacher, in Mr. J. Friend, whilst other staff both at St John’s and across the Excalibur Trust are currently taking the course.
