Carbon Reporting for Hotels and Hospitality Businesses

The Carbon Challenge for the Hospitality Sector

Hotels, restaurants, and event venues operate complex buildings with intensive energy demand — heating, cooling, kitchens, laundry, pools, and 24-hour lighting. The hospitality sector accounts for approximately 1% of global CO2 emissions and is under growing pressure from corporate travel buyers who now require supplier carbon data as part of their Scope 3 Category 6 reporting.

If your hotel or hospitality business supplies accommodation or events to corporate clients, expect to receive a supplier carbon questionnaire within the next 12 months.

Scope 1 Emissions for Hotels

The largest Scope 1 sources for hospitality are:

Natural gas — used for space heating, domestic hot water, laundry boilers, and kitchen equipment

Refrigerants — commercial kitchen refrigeration and large-scale HVAC units in hotels generate significant refrigerant leakage. Apply GWP × annual top-up weight.

Company vehicles — hotel shuttles, laundry collection, supply vehicles

Worked example — 80-room hotel, UK: - Natural gas consumption: 180,000 m³/year - Scope 1 (gas): 180,000 × 2.04 = 367,200 kgCO2e = 367.2 tCO2e

Scope 2 Emissions: Electricity

Hotels are among the most electricity-intensive commercial buildings per square metre. Lighting, lifts, laundry, refrigeration, kitchen equipment, and guest room systems all contribute.

UK example: 80-room hotel, 450,000 kWh/year × 0.193 kgCO2e/kWh = 86.9 tCO2e Scope 2

Switching to a REGO-backed renewable tariff reduces this to near zero at minimal extra cost. Solar PV on roof areas can offset 15–30% of consumption in most UK and European locations.

Scope 3 Emissions for Hospitality

Category 3 — Well-to-tank upstream fuel emissions Auto-calculated from Scope 1 gas and diesel. DEFRA 2023 WTT factors: natural gas 0.376 kgCO2e/m³, diesel 0.641 kgCO2e/litre.

Category 5 — Waste Hotels generate significant food waste, linen waste, and packaging. Apply DEFRA 2023 waste factors: landfill 0.459 kgCO2e/kg, recycling 0.021 kgCO2e/kg.

Category 1 — Food and beverage supply The embedded emissions in food and drinks purchased by hotels can be significant. A spend-based estimate using DEFRA food & catering emission factors gives a defensible estimate for Category 1.

Category 6 — Guest business travel (for buyer reporting) When a corporate client stays at your hotel, they include the hotel stay in their Scope 3 Category 6. DEFRA 2023 publishes a hotel overnight factor of 31.1 kgCO2e per night (covers all hotel activities per guest night including energy, water, food, and waste per occupied room). Report this intensity metric prominently — it is what corporate travel managers directly ask for.

The DEFRA Hotel Night Factor Explained

The 31.1 kgCO2e/night figure is an average UK hotel factor covering energy, water, laundry, food preparation, and waste per occupied room night. It is used by corporate buyers in their Scope 3 Category 6 calculations.

If your hotel is more energy-efficient than average, you can calculate a property-specific factor:

> Property-specific factor = (Total tCO2e Scope 1+2+3 operational) ÷ (occupied room nights per year) × 1,000 kgCO2e/tCO2e

This allows you to demonstrate a lower footprint per guest night than the industry default — a competitive advantage in corporate travel procurement.

Hotel Carbon Benchmarks

Source: Carbon Trust UK hotel benchmarks 2023. Higher-star hotels have higher emissions due to larger rooms, more amenities, pools, and spas.

Reduction Priorities for Hotels

1. Renewable electricity tariff — the single highest-impact action, eliminating Scope 2 entirely at low cost
2. Heat pump replacement for gas boilers — reduces Scope 1 gas significantly; payback period 5–8 years at current energy prices
3. Food waste reduction — UK hospitality wastes ~920,000 tonnes of food annually (WRAP 2022). Each tonne of food waste avoided saves ~2–3 tCO2e depending on disposal route
4. LED lighting throughout — typical hotel lighting retrofit reduces electricity consumption by 40–60%
5. Linen reuse programme — laundry is one of the most energy-intensive hotel operations; guest opt-in to multi-night linen reuse reduces both Scope 1 gas and Scope 2 electricity
