Scope 1 & 2 calculation

Calculate and document your company’s Scope 1 and Scope 2 emissions.

For your corporate carbon footprint, start with the electricity, fuel, vehicle, refrigerant and purchased-heat records you already have. We organise the activity data, apply appropriate emission factors and prepare a documented Scope 1 and Scope 2 calculation for your review.

The short version

The short version

What are Scope 1 and Scope 2 emissions?

Scope 1 covers direct greenhouse-gas emissions from sources a company owns or controls; Scope 2 covers indirect emissions from the electricity, heat, steam or cooling it purchases and consumes.

For a manufacturing company, Scope 1 usually means natural gas and other fuels burned on site, fuel used in owned vehicles, and refrigerant losses. Scope 2 usually means purchased electricity and district heating.

The split, the organisational and operational boundary, and the location-based and market-based treatment of purchased electricity follow the GHG Protocol corporate standards.

What data is needed to calculate them?

Consumption data for a defined reporting period, plus emission factors appropriate to that data.

In practice that means meter readings or invoices for electricity and heat, fuel and vehicle records, refrigerant top-up records, and the site and entity boundary the figures apply to.

Where an input has to be estimated, the assumption is recorded alongside the figure rather than absorbed into it.

What you receive

The output depends on the agreed calculation scope and the source data available.

  • Emission-factor references
  • Factor versions where relevant
  • Assumptions
  • Data-gap notes
  • Reporting boundary
  • Calculation summary
  • Supporting source mapping

How the calculation work moves

  1. Confirm boundary

    Which legal entity, sites and period are included?

  2. Collect source data

    Which quantities were consumed, purchased, burned, lost or used?

  3. Normalise units

    Values are structured by source, site, unit and period.

  4. Apply factors

    Appropriate factor sources and versions are documented.

  5. Calculate CO2e

    Activity data is converted into a traceable emissions result.

  6. Review assumptions

    Gaps, estimates, exclusions and source references remain visible.

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.

When this service fits and what you can send

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.

  • Purchased electricity

    kWh from invoices, meters or energy records.

  • 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.

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

The calculation model we preserve

Scope 1 and Scope 2 work is easier to review when each layer remains separate.

  1. Reporting boundary

    Which legal entity, sites and period are included?

  2. Activity data

    What quantity was actually consumed, purchased, burned, lost or used?

  3. Emission factor

    Which factor converts that activity into greenhouse gas emissions?

  4. CO2e

    What emissions result from the calculation?

  5. Source / version / assumptions

    Can another reviewer understand how the number was produced?

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.

Where the emissions figures usually go next

A documented Scope 1 and Scope 2 calculation is rarely the end point. The same figures are normally requested again elsewhere.

FAQ

Frequently asked questions

Is this a company footprint or a product carbon footprint?

This service calculates organisational Scope 1 and Scope 2 emissions for an agreed boundary and reporting period. It is not a product carbon footprint or full life-cycle assessment. Scope 3 and product-level work require their own scope, data and method; a company total cannot simply be presented as the footprint of one product.

What determines the cost and timing of a Scope 1 and 2 calculation?

Key factors are the number of sites and emission sources, reporting period, data completeness, units, available electricity contracts and the required Scope 2 methods. Send energy and fuel records with the company boundary and intended use. The handover includes calculation inputs, factors and their sources, assumptions and gaps, rather than only a total.

What is the difference between Scope 1, Scope 2 and Scope 3?

Scope 1 is direct emissions from sources the company owns or controls. Scope 2 is indirect emissions from purchased electricity, heat, steam and cooling. Scope 3 covers other indirect emissions across the value chain, such as purchased goods, transport and business travel. This service covers Scope 1 and Scope 2; our Scope 1, 2 and 3 explainer sets out the wider picture.

What is the difference between location-based and market-based Scope 2?

Location-based Scope 2 uses the average emissions intensity of the grid the company draws from. Market-based Scope 2 reflects contractual instruments such as a supplier-specific factor or an energy attribute certificate. The GHG Protocol Scope 2 Guidance sets out both methods; which are reported depends on the data and contracts available.

What data do we need to provide?

Electricity and heat consumption for the reporting period, fuel and vehicle records, refrigerant records where relevant, and enough company information to define the boundary. Invoices and meter readings are usually the practical starting point.

What if some consumption data is missing?

The gap is documented, and where an estimate is used the method and assumption are recorded with it. A calculated figure should always be traceable back to the input it came from.

Do we receive only the final number?

No. You receive the calculation basis: activity data, units, emission factors, factor sources, assumptions and the boundary the result applies to, so the figure can be reviewed and defended.

Is the calculation audited or verified?

No. Evipace prepares and documents the calculation; it is not an assurance or verification service. If third-party verification is required, the documented basis is what a verifier would work from.

Does this cover Scope 3?

Not as standard. Scope 3 is a separate exercise with different data requirements and a much wider boundary. Where a customer request touches Scope 3, we say so rather than silently extending the calculation.
