Everyone has an important part to play in combatting this global crisis, and the College is committed to reducing its impact on the natural environment to ensure that our day-to-day operations, our buildings, and our overall strategy put environmental sustainability at the centre of all we do.
Below we outline some of our sustainability initiatives, including our Sustainability Working Group. This page will be regularly updated with the latest news from the group, so check back to keep up-to-date with their progress.
The Sustainability working group was set up to take forward the development of an environmental sustainability plan. The group considered key areas of College operations and activities to identify where and how we can act to reduce our carbon footprint, increase biodiversity and set targets. The work of the group was informed by the Masterplan consultants, our land agents Savills, the University’s environmental sustainability strategy, and the College’s own baseline assessment of its carbon footprint with 2018/19 data.
The plan does not yet set a net zero target as data collection is still ongoing, especially from the Masterplan and our land agents, but it sets out the actions the College will or has already taken in key areas to make progress on our pathway to net zero. It is intended to be a living document that will be amended as more data becomes available, allowing us to set a realistic net zero target.

Oxford University Student Union (OUSU) has published sustainability demands of Oxford colleges to be achieved by March 2023. This note sets out the response of St John’s College to the demands.
In February 2022 we held the first meeting of the College’s Sustainability Working Group. The group is made up of representatives from across the St John’s community, including staff, students and Fellows, and is chaired by alumna Briony Fitzsimons, an expert in sustainability strategy and policy.
The group’s initial aim is to develop an environmental sustainability plan for the College, starting with examining college operations before expanding to consider our broader commercial property and agricultural portfolios. This work will contribute to the College’s overarching Environmental, Social and Governance (ESG) policy, which will consider College operations from a more general sustainability standpoint.
We are keen to hear the thoughts of the wider College community on how to make St John’s a more sustainable place to live and work. Students can contact their JCR and MCR Environment and Ethics Officers, and Fellows and staff can contact the firstname.lastname@example.org. Alumni are also welcome to contact us with their thoughts.
The Working Group has commissioned Aklimate to determine the College’s current carbon footprint and identify key commitments and actions points with regards to reducing emissions. You can find a brief summary of Aklimate’s findings in the one-page summary here.
We've included definitions of some key terms from the document below:
- Scope 1: Scope 1 emissions are the direct release of greenhouse gas emissions by the organisation, for example by running boilers and vehicles.
- Scope 2: Scope 2 emissions includes the emissions associated with purchased electricity.
- Scope 3: Scope 3 emissions are considered ‘indirect’, which means they are not directly in St John’s control, for example emissions generated by staff and students commuting.
In May 2022, the Staff and Sustainability Representatives ran the first annual St John's Sustainability Survey for staff, students and Fellows. The results of the survey will be used to inform the Working Group's actions moving forward.

We have designed College’s newest buildings with the environment in mind.
Kendrew Quadrangle, completed in 2008, includes solar panels along the roof of the east and west sections of the building, together with a biomass boiler for hot water generation. Geothermal heat pumps are installed for the underfloor heating and air conditioning, and low-energy lighting provided throughout. The north roof section consists of an array of photovoltaic panels (PV) to generate electricity for use within Kendrew Quad. The building won an Oxford City Council David Steel Sustainable Buildings Award, which recognises sustainable building developments in Oxford.
Library and Study Centre
Our Library and Study Centre incorporates passive environmental control measures designed to reduce the new building's energy consumption with an emphasis on natural ventilation and daylighting. Heating is provided by ground-source heat pumps, and a total of 40Kw photovoltaic panels on the roof.
18 Bardwell Road
18 Bardwell Road is a large 3 storey detached building in North Oxford, previously occupied by St Clare’s College which reverted back to St John’s in 2021. The building was a mixture of office and teaching space configured as 25 classrooms. The College’s aim was to refurbish and convert it for student accommodation to provide 20 graduate en suite bedrooms, with shared kitchens, including wheelchair accessible rooms.
The building sits within the North Oxford Victorian Suburb Conservation Area which creates particular challenges, yet the College were keen to create an exemplar for how Victorian buildings can be sensitively refurbished whilst significantly improving their energy efficiency and in doing so reduce their reliance upon fossil fuels and lower their carbon emissions. To this end TSH Architects with experience of low energy and Passivhaus design, and working with historic buildings were appointed to take the designs forward.
To meet the College’s intention of reducing carbon a number of measures had been allowed for as part of the design:
Insulation – Insulation installed to all external walls internally, which will dramatically improve the thermal performance from a U-Value of ~2W/m2K to ~0.6W/m2K whilst allowing the walls to ‘breathe’ as Victorian buildings where designed to do. In addition insulation has been installed in the roof voids.
Secondary glazing - The existing Victorian Sash windows allow for significant heat loss to occur through drafty unsealed, single glazed windows. Following extensive research and in line with official recommended guidance published by Historic England (Energy Efficiency and Historic Buildings: Secondary glazing for windows, April 2016), the strategy to improve the energy inefficiency of the existing windows was to install secondary internal glazing. The existing Victorian sash windows have been retained and refurbished in order that their appearance remains as existing. The secondary glazing will then significantly improve the thermal efficiency of the windows from ~4.8W/m2K to ~1.8W/m2k and reduce the risk of damage potentially caused by condensation and damp prevalent in single glazed windows.
Air Source Heat Pumps (ASHP) - In order to reduce the buildings reliance upon gas fired boilers and the carbon emissions associated with them, Air Source Heat Pumps have been installed to generate the heating and hot water for the building. No gas boilers have been installed in the building.
LED lighting – LED lighting has been installed throughout the building.
Photovoltaics - The orientation of the rear of 18 Bardwell Road, facing nigh on due South allows for the possibility of not insignificant power generation through the use of photovoltaic panels. The estimated annual generation through the use of PV is 7471 kWh/a. The estimated annual energy usage of this building is approx 45,000kWh. On this basis the PV arrays are expected to help generate approximately 16% of the building’s annual energy use. Furthermore, the PVs will assist in reducing the CO2 by 71.64 tonnes over a 20-year period. In an attempt to mitigate any harm caused by the visual appearance of the panels, an ‘Integrated PV panel’ system has been installed which sits flush with the adjacent Red clay roof tile.
In 2021 the College installed an array of 24 10kW PV panels on the south facing roof of the old sawmill building at Bagley Woods. In addition to the PV panels a 10kW battery storage unit has been installed which allows the generated electricity to be used throughout the day and night and not just when sunlight is available. This also powers the electric vehicle charging point which was provided as part of the project.
