Katy Millis, Head of Sustainability and Procurement, Dulwich College A SUSTAINABLE COLLEGE
Below are the key actions we are currently working through.
Water We will be completing the
Energy We are working on a proposal to add six solar arrays to various campus buildings. This could bring our solar production to around 25% of our total electricity consumption. In addition, we have a detailed feasibility study for replacing our natural gas-fired boilers with ground source heat pumps happening in the spring, and we hope to have full costs and plan by Easter 2024. This could reduce the campus gas consumption by 75%. We are also reviewing the action points for saving energy from our three Energy Saving Opportunity Scheme reports. These include voltage optimisation and checking the air handling is working efficiently. We are using our Building Energy Management System to identify areas of potential savings, for example reviewing set temperatures for heating systems.
installation of automated meter readers on all meters. By auditing, and therefore identifying, all meter feed locations, we can work out exactly where water is being used across the campus.
It is an honour to be working on the College’s net zero strategy, a role that includes encouraging our students through free learning during Eco Week, working with our prefect in charge of sustainability, listening to pupils’ Climate Change Society presentations, and presenting at our inaugural Sustainability Networking Event with Old Alleynians, current pupils and staff. I also work to encourage partnership schools to collaborate and share ideas. Dulwich College aims to be not only a sustainable school but also a leader in sustainability in schools, so that we can share best practice in the education sector. Our duty is the stewardship of the school for current and future generations of pupils and alumni, balancing environmental care, social wellbeing and growth. Over the past seven years the College has been working on a Sustainability Action Plan, referring to various documents including Environmental Impact reports, Energy Saving Opportunity Scheme reports, and Streamlined Energy and Carbon Reporting compliance details. We are continuing to evolve our sustainability capability and have now set targets to reach on our path to becoming a net zero organisation by 2050, in line with the Government’s legally binding aim. We first calculated our full scope 1, 2 and 3 greenhouse gas emissions for the period 1 August 2021 to 31 July 2022, and they are illustrated in the pie chart. Going forward, this data will be referred to as our baseline for future emission reduction targets. Of course, we understand emissions may go up depending on the College’s activities, and we intend to report progress on an annual basis. The baseline emissions are 6,412 tonnes of carbon dioxide, and the chart shows the source of these emissions. We have worked hard to establish a sensible trajectory, and the following short-, medium- and long-term targets have been agreed.
SHORT-TERM TARGETS TO ACHIEVE BY 2025: 15% reduction in tCO2e (tonnes of carbon dioxide equivalent) energy consumption. This may require behaviour changes on campus – turning off lights, closing windows and doors to capture heat indoors, and making sure heating is turned down when buildings are not in use at weekends and holiday periods. We are looking at how best to communicate these actions and also to highlight when savings are being achieved. 20% of suppliers with net zero targets. A large proportion of our emissions currently come from our external supply chain. Working with our top suppliers to investigate their sustainability aims will be key to driving down emissions over our medium- and long-term targets. 265 tCO2e reduction in commuting emissions. We hope we can achieve this by encouraging the use of public transport, walking and cycling. MEDIUM-TERM TARGET TO ACHIEVE BY 2030: Absolute reduction of 34% in carbon emissions versus our baseline set in 2022. LONG-TERM TARGET TO ACHIEVE BY 2045: Absolute reduction of 90% in carbon emissions versus our baseline set in 2022 .
Waste We aim to capture waste data accurately in order to minimise charges from our waste providers and maximise recycling where possible. We intend to review waste plans on the campus over the summer of 2024, with a view to incorporating communal bins rather than bins at each desk space or classroom.
Travel We are encouraging commuting by public transport, cycling and walking. We also need to maximise the use of the electric car charging points in the Old Sanitorium car park.
Biodiversity Our fantastic grounds team are creating wilding corridors to encourage natural habitats for insects and wildlife, and we are establishing casual quiet areas across the campus to encourage wellbeing for students and staff. We also have very active forest schools for our DUCKS students and our younger students on the main campus. These aim to help the pupils understand the outdoors within the College campus and learn to love the outdoors as a stimulus for all senses.

Supply chain We are engaging with suppliers in order to create a green supplier list. We need to consolidate orders and therefore cut down on the number of deliveries to campus. We will be reviewing food purchasing and waste, and reducing meat and dairy consumption.
