The Diocese of Oxford has committed to working towards net zero carbon emissions by 2035. This means supporting our churches, schools, vicarages, offices to reduce their emissions as far as possible, as well as looking at the impact of some of our resources.
So far:
• Over 300 churches have had an energy audit
• £10m investment has been committed for our clergy houses, and 51 properties retrofitted in 2024
• £1.5m has been invested in our schools for energy efficiency improvements
Read our net zero carbon action plan, and our latest annual carbon emissions report, which was published in November 2024.
The Big Switch for creation
This Creationtide we are encouraging all churches to switch to a renewable energy tariff. It is a relatively small step we can take, but with a potentially big impact. Across the diocese, we already know of 239 churches that are on a renewable electricity tariff, according to data from the Energy Footprint Tool (2024). Your church can make the switch too.
The Church of England have developed a robust definition for a green energy tariff, and have compiled a list of suppliers that meet this criteria. This list will be updated annually.
More information on the definition of a green tariff, the Parish Energy scheme and guidance on switching will be released shortly.
Supporting churches to net zero carbon
'Our net zero journey so far' - webinar recording
On 6 May 2025 we ran the first of two webinars, to hear from churches that have progressed their plans for net zero. Watch the recording to find out:
- what they did first
- who they involved (professionals, consultants etc)
- what unexpected challenges they have encountered
- their top tips for other churches embarking on this journey
Our next webinar will run on 9 October from 1-2pm. All are welcome, register to join.
Carbon Confidence in an Hour
Our new 'Carbon Confidence training' can be delivered in-person or online to your PCC, Deanery Synod, or other church event. Contact us to arrange a session. Alternatively, the training can be done on your own or in a small group, using the video below. Allow up to an hour for this session. The training covers:
- The missional context
- The science of climate change
- Climate justice and climate impacts
- Carbon footprints
- Case studies of action
- Looking to the future
Fundraising for net zero carbon
For regular funding opportunities, sign up to our Care for Creation newsletter. Every parish can also have free access to Cornerstone, a searchable grants database. Contact the Generous Giving Advisor for access and for an introduction to the database.
Details of national church net zero carbon grants, along with application forms and guidance documents, will be available from January 2026 as part of the next round of triennium funding. Any churches wishing to apply for these grants will need to have completed the Energy Footprint Tool to be eligible.
Getting started
There are four things all churches can do to start their net zero carbon journey
Thank you to all those who completed this year’s Parish Returns Energy Footprint Tool (EFT). The data gathered is used to establish the Church of England's carbon baseline and monitor progress, to track the impact of the steps your church is taking to reduce your emissions. It ensures your church is eligible for net zero carbon grants. At a Diocesan level it also helps us to:
- Spot churches with heating system issues.
- Identify which churches would benefit from an energy audit.
- Discover examples of good practices to share.
If you missed the deadline this year, please contact the Environment Team to find out how to share your data.
The Tool will open again in January 2026 to record 2025 energy use totals.
The diocese offers tailored advice to help your church reduce its environmental footprint and save money on energy bills through an energy audit. This includes a decarbonisation plan with long-term actions to reach net zero.
Currently nearly 40% of churches are on a renewable energy tariff. It’s the quickest way to reduce your carbon emissions, and support investment in renewable energy. The Church of England has an approved list of renewable energy suppliers, which is updated annually.
Find out how to turn your church's energy audit recommendations into a deliverable action plan with our simple, step by step guidance, 'From audit to action plan'. Begin with the quick-wins that focus on energy efficiency, and start planning for the bigger changes.
