A practical checklist for your faith-based organisation on the road to carbon zero

Caring for the natural world is a value shared across faith traditions — stewardship of creation, the trust (amanah) placed in humanity, the call to protect what we've been given. For faith-based organisations, reaching net zero carbon is one of the most tangible ways to live that value. It can feel daunting, especially for communities meeting in old, hard-to-heat buildings. But it is achievable when broken into practical, affordable stages.

This article offers a staged checklist and points you to established schemes you can plug into — so you're not starting from scratch.

Why this matters now

Beyond the spiritual motivation, there are practical pressures: rising energy costs, growing expectations from funders and younger members, and in some traditions formal commitments (for example, the Church of England's net-zero carbon target). Acting also saves money — energy efficiency and renewable generation can free up funds for community work.

A note on definitions: "net zero" generally means reducing your emissions as far as possible, then offsetting only the small remainder through credible schemes. The emphasis belongs firmly on reduction first — offsetting is the last resort, not the strategy.

Step 1 — Measure your starting point

You can't manage what you haven't measured.

• [ ] Gather 12 months of energy bills (gas, electricity, oil)
• [ ] Note major travel associated with the organisation
• [ ] Use a carbon calculator designed for places of worship to establish a baseline
• [ ] Record it so you can track progress year on year

Step 2 — Tackle the building

For most places of worship, the building is the biggest source of emissions — and listed-building rules can constrain what's possible, so check before you alter anything historic.

• [ ] Switch to LED lighting throughout (one of the easiest wins)
• [ ] Improve insulation where permitted — roof, loft and draught-proofing first
• [ ] Consider secondary glazing or other heritage-sensitive measures for windows
• [ ] Review heating — is the system efficient, well-controlled, and only heating occupied spaces when needed? Modern controls and zoning can cut waste dramatically
• [ ] Explore heat pumps where the building and budget allow

Step 3 — Address energy supply

• [ ] Move to a renewable / green energy tariff
• [ ] Assess the potential for solar panels (rooftop PV) — even partial generation reduces both bills and emissions
• [ ] Consider rainwater or greywater harvesting where feasible
• [ ] Look at battery storage if you generate your own power

Step 4 — Behaviour, travel and procurement

• [ ] Encourage walking, cycling, public transport and car-sharing to services and events
• [ ] Choose ethical and sustainable suppliers; reduce single-use plastics (for example, communal water dispensers instead of bottles)
• [ ] Cut waste — including food waste at community meals; consider surplus-food partnerships
• [ ] Consider biodiversity on any land or grounds you hold — pollinator-friendly planting, trees, even beehives

Step 5 — Fund the work

• [ ] Build major measures into your reserves planning and budget (see setting a reserves policy)
• [ ] Research grants for energy efficiency and heritage buildings
• [ ] Important — VAT relief is changing. The Listed Places of Worship Grant Scheme, which reclaimed VAT on repairs to listed worship buildings, is closing on 31 March 2026 and being replaced by a new heritage funding package whose terms were not yet published as of June 2026. Don't assume the old basis will continue — check the current position before budgeting.
• [ ] Consider whether a legacy gift or dedicated appeal could fund a major project such as solar installation

Recognised schemes to plug into

You don't have to do this alone. Established, faith-specific programmes provide frameworks, surveys and community support:

• Eco Church (run by A Rocha UK) equips churches in England and Wales across five areas — worship and teaching, buildings, land, community engagement and lifestyle — with Bronze, Silver and Gold awards to mark progress. Scotland has Eco-Congregation Scotland; Catholic communities can use CAFOD's LiveSimply; there's an equivalent in Ireland too.
• Greening our Mosques (an Islamic Relief UK initiative) supports mosques to lead by example — from communal water dispensers to solar installation — with practical guides rooted in Islamic teaching on environmental responsibility. The Cambridge Central Mosque, opened in 2019, is Europe's first purpose-built eco-mosque, with rooftop solar, heat pumps and rainwater harvesting — a striking proof of what's possible.

Whatever your tradition, the pattern is the same: a recognised framework, a survey to benchmark where you are, and a community of others on the same road.

A copy-out summary

1. Measure — baseline your footprint
2. Building — LEDs, insulation, efficient heating (mind heritage rules)
3. Supply — green tariff, solar, water harvesting
4. Behaviour — travel, procurement, waste, biodiversity
5. Fund it — reserves, grants (note the LPW change), appeals
6. Plug in — Eco Church, Greening our Mosques, or your tradition's scheme

Start with the easy wins. Momentum and visible savings build the will for the bigger steps.
