Manual Entry

Last updated 19 days ago

Manual Entry is a data input method where emission calculations are performed individually and directly by the user within the system. It is particularly suitable for organizations with limited data volumes or for single, activity-based calculations.

The Manual Entry screen can be accessed via the Manual Entry tab under the Data Entry+ module.

Facility Settings

Before starting a manual emission calculation, the facility for which the calculation will be performed must be selected.

In the Facility Settings section, the following information related to the selected facility is displayed:

  • Facility name

  • Facility type (e.g., Office)

  • Country and city information

  • Emission profile

The emission sources (emission factors) listed on the Manual Entry screen are those that have been previously defined under the selected facility’s Emission Profile. Therefore, only emission factors included in the relevant emission profile can be used in manual calculations.

Date Range Selection

On the Manual Emission Calculation screen, the start and end dates to be included in the calculation are defined. This date range represents the period covered by the entered activity data.

For example, if a calculation is based on an invoice, the consumption period stated on the invoice should be defined here.

Calculation Method

Before performing the calculation, the calculation method must be selected:

  • Activity-based

  • Spend-based

This selection determines which emission factors will be listed in the system. If an activity-based emission factor is to be used, the activity-based method should be selected; if the calculation is based on financial values, the spend-based method should be selected.

Emission Source and Unit Selection

After selecting the calculation method:

  • Emission Source is selected. This represents the emission factors added to the emission profile of the selected facility.

  • Unit is selected. Unit options are also listed based on the units defined in the emission profile.

Activity Data Entry

In this field, the consumption amount or activity data used as the basis for the calculation is entered.
Examples include the amount of fuel used, energy consumed, or quantity of products purchased.

Supplier Information (Optional)

Selecting a supplier is not mandatory; however, associating emissions with a supplier provides a significant advantage.

When supplier information is entered, emissions are linked to the relevant supplier. This allows users to track how much emission originates from each supplier in the Supplier Management and analysis modules.

Description and Supporting Documents

Optionally, users can:

  • Add additional information related to the activity in the Description field

  • Upload supporting documents

Examples include:

  • Natural gas invoices

  • Electricity invoices

  • Other documents supporting the activity data

These documents serve as references for audit and verification processes.

Calculation and Results Management

After completing the required fields, click Calculate.

Once the calculation is completed:

  • The performed calculations are displayed in the Last 5 Results section at the bottom of the screen

  • For each record, the ⋯ (three-dot) menu allows users to:

    • Edit the record

    • Delete the record

All calculation results can be viewed in detail on the Results page. Each record is listed with the facility, category, date range, emission factor used, and calculated tCO₂e value.

Manual Emission Calculation – Subcategory-Specific Explanations

On the Manual Emission Calculation screen, data entry fields may vary depending on the selected scope (Scope 1, 2, or 3) and subcategory. This structure is designed to ensure accurate emission mapping in line with GHG Protocol and ISO standards.

Purchased Goods and Services

In this subcategory, there are two separate options: Products and Services.

  • Products should be selected when purchasing physical goods

  • Services should be selected when purchasing services (e.g., water supply, consulting)

If an incorrect option is selected, ISO and GHG mapping of emissions may be inaccurate.

When the spend-based method is selected, the system uses spend-based emission factors added to the emission profile. The currency used for activity data entry (USD, EUR, TRY, etc.) can be selected, and Carbondeck automatically performs all currency conversions.

Upstream / Downstream Transportation & Distribution and Travel

In these categories, emissions related to road, sea, air, and rail transportation are calculated. In general, two main data points are required:

  • Distance

  • Weight (for freight transport) or number of people (for travel)

Special Case: Air Transportation

For air transport calculations, two data entry types are available:

  • Distance

  • Port (Airport-based)

When the Port option is selected, departure and arrival airport codes are entered, and the distance between the two airports is automatically calculated by Carbondeck. The user only needs to enter the weight (for cargo) or number of people (for travel).

Franchises

When calculating franchise emissions:

  • A franchise previously defined in the Settings section is selected

  • The franchise’s Scope 1 and Scope 2 emissions are entered

Investments

In the Investments category:

  • A company defined in the Settings section is selected

  • The calculation year is specified

  • The company’s Scope 1, Scope 2, and Scope 3 emissions are entered

This approach is aligned with the GHG Protocol Financed Emissions methodology.
