Carbon Reporting for Charities and Nonprofits: A Practical Guide
Why Charities and Nonprofits Need to Report Carbon Emissions
Carbon reporting for charities and nonprofits has moved from voluntary best practice to practical necessity in 2026. Three drivers are pushing organisations that historically had no sustainability obligation to measure and disclose their emissions:
1. Funder and grant requirements — Major UK funders including the National Lottery Community Fund, Arts Council England, and Comic Relief now ask grant applicants and recipients about their environmental impact. Some require a carbon measurement as a condition of grants above certain thresholds.
2. Government and local authority contracts — Public sector procurement in the UK (under PPN 06/21), Scotland, and EU member states increasingly includes environmental sustainability requirements in tender evaluation. Charities winning government contracts are expected to have measured their carbon footprint.
3. Corporate partnership expectations — When a charity forms a corporate partnership with a large business subject to CSRD or SECR, that business may include the charity's activities in their Scope 3 Category 15 (investments) or upstream supply chain — and will ask for carbon data.
What Does a Charity's Carbon Footprint Actually Cover?
Charities and nonprofits have relatively simple emissions profiles compared to manufacturing businesses:
Scope 1 — Direct emissions: - Gas heating in offices, community centres, or care facilities - Diesel or petrol for charity vehicles (fleet, volunteer transport) - Refrigerant leaks from air conditioning (if applicable)
Scope 2 — Electricity: - Office and premises electricity - Electric vehicle charging (if fleet is electric)
Scope 3 — Indirect emissions: - Category 6 — Staff and volunteer business travel (rail, flights, car mileage) - Category 7 — Staff commuting - Category 5 — Waste from offices and events - Category 1 — Purchased goods (office supplies, printed materials)
Worked Example: UK Small Charity Carbon Calculation
Sample organisation: A 12-person UK charity with one office
Scope 1 — Gas: 12,000 m³ × 2.204 = 26,448 kgCO2e = 26.4 tCO2e
Scope 2 — Electricity: 18,000 kWh × 0.207 = 3,726 kgCO2e = 3.7 tCO2e
Scope 3 — Business travel (rail + car): 4.2 tCO2e
Scope 3 — Commuting (12 staff): 5.8 tCO2e
Scope 3 — Waste: 0.4 tCO2e
Total: 40.5 tCO2e | Per employee: 3.4 tCO2e/FTE
For a small charity, this total is modest — but having a measured, documented figure is far more credible with funders than a statement of "we try to be environmentally responsible."
What Do Funders Actually Ask About Carbon?
Different funders ask different questions. Common requests:
| Funder Type | What They Ask |
|---|---|
| National Lottery Community Fund | Environmental impact statement; are you tracking emissions? |
| Arts Council England | Carbon reduction commitments; have you measured your footprint? |
| Local authority contracts | Carbon Management Plan; Scope 1 and 2 targets |
| Corporate partners (CSRD) | Scope 1, 2, 3 in tCO2e; GHG Protocol methodology |

Frequently Asked Questions
Do charities need to report their carbon emissions?
Most UK charities are not legally required to report carbon emissions. However, major funders (National Lottery Community Fund, Arts Council England, Comic Relief), local authority contracts under PPN 06/21, and corporate partnerships with CSRD-regulated companies increasingly require or expect carbon disclosure. Having a measured carbon footprint strengthens grant applications and demonstrates credibility on sustainability.
What does a charity's carbon footprint cover?
A charity's carbon footprint typically covers Scope 1 (gas heating, charity vehicles), Scope 2 (office and premises electricity), and Scope 3 (staff business travel and volunteer travel — Category 6; staff commuting — Category 7; waste — Category 5). For charities with retail operations or large event programmes, additional Scope 3 categories may be relevant.
Do we include volunteer travel in our carbon footprint?
The GHG Protocol does not specifically require volunteer travel in a standard corporate carbon footprint — volunteers are not employees. However, some funders and B Corp assessors ask for volunteer travel as part of a broader organisational footprint. If volunteers travel significant distances for your charity's work, including them provides a more complete picture and demonstrates transparency.
How do we report our carbon footprint to a funder?
Most funder carbon questionnaires ask for total tCO2e for the most recent complete financial year, the methodology used (GHG Protocol is the standard answer), and any reduction target or commitment. A DeCarbonOPS Carbon Passport provides your Scope 1, 2, and 3 totals with a permanent verification URL that can be referenced in grant applications and submitted as supporting evidence.
Is DeCarbonOPS free for charities?
DeCarbonOPS is free for your first annual Carbon Passport report — whether you are a charity, nonprofit, or commercial business. There is no credit card required to sign up. Your first report gives you a complete Scope 1, 2, and 3 calculation with a shareable verification URL.
