Sustaining Sustainability

This week Mrs Franklin (the Academy’s Sustainability and Marketing Manager) joined me to present to a national conference of School Business Leaders. We were asked to present our work on reducing the Academy’s carbon footprint towards our goal of net-zero by 2030, and we also took the opportunity to look more broadly at our sustainability priority.

Many of the things we spoke about in our presentation are captured in the blog post I wrote around the #COP26 summit in Glasgow last November – Going Green: Churchill and #COP26. We emphasised how important it is to us that sustainability is one of the five priorities in the Academy’s five-year strategic plan, and that sustainability is driven by our students – as we owe it to them to protect the planet they will grow up on. In fact, I will be judging the students’ Seeking Sustainability competition entries next week!

Mrs Franklin was able to update the conference delegates on the impact of some of our carbon reduction work:

  • Reviewing our controls and boiler optimisation so that boilers are only on when they are absolutely needed has saved 22,000 kWh of energy
  • The replacement of our lighting with LED units has saved 150,000 kWh on electricity
  • The solar panels (or photovoltaic cells as they’re more properly called) which cover much of our roof space across the site can deliver up to 40% of the Academy’s electricity needs in peak summer weather
  • The introduction of point-of-use hot water heaters mean that our boilers can be completely switched off for long periods of time in warm weather, saving 300,000 kWh in gas

Finally, Mrs Franklin was able to present an updated carbon emissions chart which shows we have reduced our carbon footprint by 70% since 2015 – a further 20% reduction since the 2020 figures.

This presentation wasn’t all celebration however. As a school, we have picked almost all of the “low hanging fruit” in our battle to reduce our carbon footprint. The next stage of our journey to net zero involves the bigger challenge: reducing or removing our dependence on natural gas completely. As we look at heating and cooling solutions across the Academy’s estate, to replace our ageing gas boilers, we really want to find low-carbon solutions. Our Trustees last week commissioned work to explore how best to achieve this.

What we already know is that we will need additional funding to enable this work. We also know that the Department for Education is facing an estimated £11.4 billion bill just to bring the school building estate up to standard across the UK – and that’s before they begin to think about decarbonising that estate. And so, whilst we are grateful for the existence of the DfE’s Sustainability and climate change: a strategy for the education and children’s services systems – we feel that it doesn’t go far enough. If we are serious about net zero, we need to tackle the big ticket items which contribute to our carbon footprint: gas-fired heating systems, and emissions from transport. Whilst we can make progress on these issues ourselves, we’re going to need help if we’re going to solve them for good – and that means investment to back up the sentiments.

We know our students are ambitious for a greener future – and we owe it to them to deliver it.

  1. Great ambitions. Maybe you could look at the need for the car park light to be on as much as it is, a small thing but ‘every little helps’.

    Especially in view of the fact we are in a bat zone. and need our dark skies.

    Well done for your work so far and influencing the students in ways to reduce their carbon footprints. Hopefully they will then call out the parents that are not mindful of doing their bit.
