Espresso machine and equipment
Their consumption is already part of the electricity bill: it is not added a second time.
Back to activities
Bars and cafés
Your bar, a meeting point. For the planet too.
Know the emissions of your energy consumption, reduce where possible, and consider offsetting by supporting documented projects.
The venue in operation
From breakfast to the last cup.
The bill combines many uses together. The calculator avoids adding up individual appliances again.
Counter and refrigeration
Energy is included in the bill; any refrigerant leaks require separate technical data.
Washing and any kitchen use
Dishwashers, hot water and preparation affect consumption through electricity or fuels actually declared.
Lighting and air conditioning
Lighting and comfort of the venue are included in annual consumption, without estimates per individual appliance.
Readable data starts with the right period.
Twelve full months allow you to understand seasonality, air conditioning and the bar's real pace.
From data to action
Understand, reduce, then offset.
- 01
Data
Collect twelve months of bills and separate the energy sources actually used.
- 02
Estimate
Calculate the CO₂ of consumption with stated factors, units and year.
- 03
Reduction
Review hours, temperatures, maintenance and equipment without duplicating consumption.
- 04
Documented contribution
After reduction, the remaining emissions can be complemented by documented projects and retirements.
Offsetting complements emission reduction. The calculator's result does not prove that a contribution or retirement took place.
Bar calculator
Estimate the emissions of energy consumption.
Enter your bills' annual data. Empty fields remain excluded; no standard consumption is attributed to a cup.

How we calculate emissions
For each source we apply annual consumption × kg CO₂ factor per unit. We only sum results expressed in the same CO₂ indicator. We do not arbitrarily convert m³ into kWh and do not include WTT or life cycle.

|---|---|---|---|---|
| Elettricità acquistata | 0,1926 kg CO₂/kWh | 2024 definitivo Italia, consumo nazionale | CO₂ della produzione elettrica consumata | ISPRA, Rapporto 430/2026 — allegato «FE_energia_elettrica_2025-V2.xlsx», foglio «9», colonna «Consumi elettrici», riga anno 2024 (192,595 g CO₂/kWh); verificato sul file ufficiale il 2026-09-15 |

Included
Purchased electricity and on-site combustion of the stated sources over twelve months.
Excluded
Coffee, milk, ingredients, refrigerants, packaging, waste, deliveries, equipment and life cycle.
Primary sources, rows and limits
Electricity: final Italian national consumption factor for 2024 from ISPRA, 192.6 g CO₂/kWh, i.e. 0.1926 kg CO₂/kWh. Natural gas and LPG: only the Scope 1 CO₂ component from DESNZ 2026 used as a UK proxy, respectively 2.02231 kg/m³, 0.18194 kg/kWh GCV and 1.55491 kg/l. No WTT.
From the counter to people
A gesture at the till, a contribution that keeps going.
In the agreed journey, customers can choose to take part; the till prints a code on the receipt to redeem online. Compatibility and configuration must be checked for each system.
