Restaurants
Your restaurant can do its part. For the planet too.
Know the emissions of your energy consumption, reduce where possible, and consider a documented contribution for the remaining ones.
Where to start
Every service has consumption and boundaries that need to be made explicit.
The calculator covers energy. Other sources require their own data and are not approximated with an average per meal.
Food and supplies
These are relevant for a broader inventory, but do not enter the energy calculator without specific data and method.
Refrigeration
Electricity consumption is included; any refrigerant leaks require separate technical data.
Waste and transport
These must be assessed with documented quantities, destinations and distances: they are not estimated automatically.
Data quality comes from everyday work.
Complete bills, a consistent period and distinct sources make the estimate readable and repeatable.
From data to action
Measure well, reduce first, document afterwards.
- 01
Data
Collect twelve months of bills and define the scope of the venue.
- 02
Estimate
Convert energy consumption into CO₂ with stated factors and consistent units.
- 03
Reduction
Identify actions on equipment, temperatures, timing and energy waste.
- 04
Documented contribution
For the remaining emissions, consider projects and documentation separate from the simple calculation.
Offsetting complements emission reduction. The estimate does not prove that a contribution or a retirement took place.
Restaurant calculator
Estimate the emissions of energy consumption.
Enter real annual data from your bills. Empty fields remain excluded and do not automatically become zero.

How we calculate emissions
For each source: annual consumption × kg CO₂ factor per unit. We only sum results with the same CO₂ indicator. We do not arbitrarily convert Smc into kWh and do not include upstream components or life cycle.

Included
Purchased electricity and on-site combustion of only the stated sources over twelve months.
Excluded
Food, beverages, refrigerants, waste, deliveries, goods, works and the full life cycle of the venue.
Primary sources, rows and limits
For electricity we use the final Italian national consumption factor for 2024 from ISPRA: 192.6 g CO₂/kWh, i.e. 0.1926 kg CO₂/kWh. For natural gas and LPG we use only the Scope 1 CO₂ component from DESNZ 2026 as a UK proxy: 2.02231 kg/m³; 0.18194 kg/kWh GCV; 1.55491 kg/l LPG. The factors do not include WTT.
From the venue to people
Involve your customers at the till too.
In the journey already planned for points of sale, the till integration can print a code on the receipt to redeem online. Configuration and compatibility must be checked for each system.
