Sustainability

Sustainability at Dulwich College

Sustainability is integrated throughout our school, from infrastructure changes to student-led initiatives. We are committed to reducing our carbon footprint, setting short, medium and long-term goals, aiming to lead sustainability within the education sector.   

Total emissions per year

The graph below illustrates our scope 1, 2 and 3 emissions since our benchmark year (FY2022):  

Although our emissions have increased since benchmark, there has been increased granularity in data collection, increasing accuracy of our carbon footprint, and allowing us to more accurately identify different areas to reduce our environmental impact.  

Targeted Carbon Reduction

In aim of achieving net zero by 2045, we have set short-, medium-, and long-term goals to work towards.  

Short term (by 2025) 

We have focused on energy, commuting, and improving supplier sustainability through the following targets:  

  • 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 

We have successfully achieved a 15% reduction in scope 1 & 2 emissions, and have engaged our top 10 suppliers in discussions on how we can collaborate to achieve our shared sustainability goals.   

Medium term (by 2030)  

  • 34% reduction across all scopes  

We aim to achieve this by reducing gas and electricity use where possible, exploring sustainable alternatives to our gas network, promoting more sustainable school travel (including trips & expeditions), and prioritising responsible purchasing from our suppliers within scope 3 emissions.  

Long term (by 2045) 

  • Net zero by 2045 (90% reduction across all scopes, offsetting the remaining 10%) 

We will track our progress and alter our trajectory to accommodate any changes to achieve our overarching target. 

Regulations and recognition 

Through the implementation of targets, we have been able to focus on certain areas and cut our major emitters. We are committed to emissions reduction through regulations such as Energy Savings Opportunity Scheme (ESOS) and Streamlined Energy and Carbon Reporting (SECR). We have achieved the following: 

  • EMA Awards 2025: Energy Efficiency Project of the Year  

  • AA1000 accreditation, ensuring credible and transparent sustainability reporting  

  • Education Estates Conference Awards 2025: Project of the Year, Independent School 

  • TfL Gold standard, reflecting our efforts in active and public transport commuting 

  • ‘Best of the Best: Green Initiatives’ in the Week’s Independent School Guide 

Our 2025 Eco Week will cover a range of topics, driving pupil and staff engagement through a variety of initiatives focused around thinking differently. We hope this week can provide education for individuals on green initiatives and how we can reduce our individual environmental impact.   

Sustainability Communications 

We have increased communications around sustainability, through the following initiatives: 

  • Sustainability Spotlight (monthly sustainability newsletter)  

  • Poster coverage across campus  

  • Introduction of Sustainability Action Group, meeting half termly

“I enjoy working on our Net Zero Strategy with the College Community, to encourage our students through Academic Enrichment 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”
