Scope 1 & 2 calculation
Scope 1 and Scope 2 emissions calculated from your actual company data.
If a customer asks for your company's Scope 1 and Scope 2 emissions, the starting point is not a CO2 number.
It is the underlying activity data: electricity, fuels, vehicles, refrigerants, purchased heat and other relevant sources.
Evipace structures the data, applies appropriate emission factors and prepares a documented calculation you can review.

Source data
What data do we usually start with?
Not every company has every source. The relevant dataset depends on the reporting boundary, facilities and operations.
Stationary fuels
Natural gas, heating oil, LPG or other fuels used on site where relevant.
Company vehicles
Fuel consumption or other relevant fleet activity data for mobile combustion.
Refrigerants
Refrigerant losses or top-ups where relevant.
Process emissions
Only where relevant to the company's operations.
Purchased heat, steam or cooling
Where applicable and inside the reporting boundary.
Calculation service
From source data to a calculation you can trace.
We keep the calculation layers visible so another reviewer can understand how the number was produced.
Boundary review
We clarify which entity, sites and reporting period belong in the calculation.
Data structuring
We normalise activity data by source, site, unit and period.
Data-gap review
We identify missing periods, unclear units and incomplete sources.
Factor selection
We use appropriate factor sources and document the factor and version used.
Calculation
We convert activity data into CO2e using a documented methodology.
Scope classification
Relevant emissions are structured into Scope 1 and Scope 2 according to the applicable calculation framework.
Review package
We keep source references, assumptions and calculation logic visible for internal review.
Send the source data you already have.
Do not clean everything first. Invoices, exports and prior calculations are useful even when they are not yet organised into a complete dataset.
- Electricity invoices
- Electricity consumption exports
- Gas or fuel invoices
- Fleet fuel data
- Refrigerant service records
- District heating invoices
- Site list
- Reporting-period information
- Existing calculations
- Prior carbon reports
How the calculation work moves
- 01
Confirm boundary
Which legal entity, sites and period are included?
- 02
Collect source data
Which quantities were consumed, purchased, burned, lost or used?
- 03
Normalise units
Values are structured by source, site, unit and period.
- 04
Apply factors
Appropriate factor sources and versions are documented.
- 05
Calculate CO2e
Activity data is converted into a traceable emissions result.
- 06
Review assumptions
Gaps, estimates, exclusions and source references remain visible.
The calculation model we preserve
Scope 1 and Scope 2 work is easier to review when each layer remains separate.
- 01
Reporting boundary
Which legal entity, sites and period are included?
- 02
Activity data
What quantity was actually consumed, purchased, burned, lost or used?
- 03
Emission factor
Which factor converts that activity into greenhouse gas emissions?
- 04
CO2e
What emissions result from the calculation?
- 05
Source / version / assumptions
Can another reviewer understand how the number was produced?
What you receive
The output depends on the agreed calculation scope and the source data available.
- Structured Scope 1 activity data
- Structured Scope 2 activity data
- CO2e calculation
- Emission-factor references
- Factor versions where relevant
- Assumptions
- Data-gap notes
- Reporting boundary
- Calculation summary
- Supporting source mapping
Scope boundaries
What this service is not
This is calculation preparation, not assurance or certification.
Where the underlying methodology requires a distinction between location-based and market-based Scope 2, we explain and document it conservatively. Renewable electricity claims do not automatically make Scope 2 zero.
Scope 3
Not automatically included.
Product carbon footprint
Not included unless separately scoped.
Third-party assurance
Not provided by this service.
Certification
No certification claim is made.
Legal compliance opinion
Not part of the calculation service.
