From 18 to 22 November, DUCKS celebrated Eco Week, uniting pupils, staff, and the wider College community to promote sustainability and foster a deeper connection with nature.
Sustainability
Sustainability is key to securing the College for future Alleynians.
Our duty is the stewardship of the College for current and future generations of pupils and alumni, balancing environmental care, social well-being and growth. We aim to become a leader in sustainability in schools, sharing best practice with others.
Sustainability at Dulwich College
Student focus on Sustainability
Sustainability features across the Dulwich College curriculum and our pupils enjoy a variety of activities relating to Sustainability: Forest school, Climate Change society, creative writing outdoors. There is an annual Free Learning Eco week every November which includes visiting speakers, student-led talks and a plethora of creative activities.
Baseline Carbon Footprint
We first calculated our full scope 1, 2 and 3 greenhouse gas emissions for the 12-month period to 31 July 2022, this now forms our carbon baseline for future emission reduction targets. Our carbon emissions totalled 8440 tonnes in this period.
In for year-end 31 July 2023 our total emissions were calculated and have shown an increase to 9859 tCo2e.
Travel was restricted due to Covid 19 in our first year of calculations, therefore trips and travel were limited. We have seen an increase in emissions from this category as more trips have been able to take place and our boarding community has been able to return to their home countries more frequently during holiday periods.
We have also seen a rise in expenditure across all subcategories within our purchased goods, however we are confident that we will be able to make significant changes within the departments we are reviewing in detail, for example, food purchasing, we are currently reviewing our menus to reduce red meat consumption and introduce a plant-based day.
We continue to evolve our sustainability capability and have agreed targets to navigate our path to become a net zero organisation by 2050 in line with the Government’s legally binding aim.
Our emissions are split across categories and are shown in the chart below:

Targeted Carbon Reduction
We have established a sensible trajectory to net zero, and the following short, medium- and long-term targets have been agreed by our Governors and CLT:
Short term by 2025
We will focus on energy and commuting reduction and moving to a new way of working with our suppliers through:
- 15% reduction against the baseline in our Scope 1 & 2 emissions
- 10% reduction in commuting
- 20% of our suppliers to have a net zero target
Through engagement with our main suppliers, we will establish their planned methodologies to cut carbon emissions and for our small suppliers we will share best practice on lowering the impact of the service they offer the College.
Medium term by 2030
This target requires the College to reduce its carbon emissions by 34% across all scopes. Key to achieving this will be finding sustainable energy alternatives to our current gas reliant footprint. We will also focus on scope 3 supplier purchases and action a sustainable travel and transport strategy.
Long term by 2045
The College aims to reduce its carbon footprint by 90% by 2045 to be on track for the Government’s target of net zero by 2050. New technology will evolve in the near future which we anticipate will afford us further opportunities, our likely challenge will be financial affordability. We will track our progress and alter our trajectory to accommodate any changes to achieve our overarching target.
Work to date
We have a Sustainability Action Plan we use to guide us through the complex steps of decarbonisation. We have in place a Sustainability Action Plan. We have a range of supporting documents including our latest Environmental Impact Report, Energy Saving Opportunity Scheme [ESOS] reports, and Streamlined Energy and Carbon Reporting [SECR] compliance details. These have all informed the activities and projects we are pursuing.
Current Decarbonising major Projects
We are exploring ways to decarbonise now and for future generations of custodians of the College:
-
Increasing Solar power generation
We want to increase our solar generation beyond the capacity of our existing solar arrays (on the Laboratory, swimming pool roof and the Lord George building) and are actively planning to add more panels to The Laboratory and Lord George buildings plus install new arrays on the Christison Hall, Sports Hall, Art and DT block and the Lower School. We believe we can generate c25% of the electricity we use on campus by sunshine.
The tender process is live and we intend to start work this year.
-
Heating using energy from Ground Source Heat Pumps (GSHP)
We are working with an external consultant on the feasibility (operational and financial) to install GSHPs across the SE21 campus. The intent of this project is to reduce our usage of gas by over 60% and reduce our carbon footprint by at least 800 tonnes per year.
We will have a detailed design and plan with full costs later this year.
Work in progress
Energy
- Solar and GSHP evaluation
- Prioritising Energy Savings Opportunity scheme report actions
- Using installed tools such as our Building management system to control heating timings and temperature
Water
- Complete the installation of automated meter readings on meters to track use in all areas
- Auditing all meter feed locations
- Harvesting rainwater across the campus
Waste
- Capturing total waste data accurately
- Recycling where possible increasing total %
- Reviewing waste plans within the Classroom
- Engaging local Council in waste strategy
Travel
- Reviewing travel on trips and expeditions
- Encouraging commuting by public transport, cycling and walking
- Maximising use of EV chargers
Supply chain
- Engaging with suppliers thus beginning to create a green supplier list
- Consolidating ordering and deliveries
- Reviewing food purchasing and waste, reducing meat and dairy consumed
Biodiversity
- Creating wilding corridor
- Establishing quiet areas
- Encouraging activity and interest in the outdoors
Katy Millis, Head of Sustainability and Procurement
“I enjoy working on our Net Zero Strategy with the College Community, to encourage our students through Free Learning during Eco week, being involved with our prefect in charge of Sustainability and listening to Climate Change Society presentations by pupils with particular interests in Environmental issues.
It was great to present our achievements to date at our inaugural Sustainability Networking event with Old Alleynians, current pupils and staff and to encourage partnership schools to collaborate and share ideas”
