The Sumday Calculated dataset is a special database in Sumday that gives you extra flexibility when inputting data outside of industry or supplier emission factors.
This dataset is designed to support:
Direct entry of supplier-provided CO₂e values
Tracking zero-emission activities such as walking, cycling or renewable electricity
Custom scenarios that allow traceability in audits and reporting
What emission factors are in the Sumday Calculated dataset?
The dataset includes several types of emission factors:
1. Direct CO₂/CO₂e Entry Factors (1:1 conversion)
Custom factors labelled “Direct CO₂/CO₂e Entry” exist across multiple GHG categories.
Each has a conversion of 1 unit = 1 kg CO₂e.
This lets you enter emissions directly into Sumday, with no need for extra calculations.
Available across categories such as Business Travel, Purchased Goods & Services, Waste, Transportation, Investments, Use of Sold Products, and more.
2. Zero Emission Electricity Factors
Zero Emission Electricity (Scope 2): Available for many countries, allowing you to reflect renewable or low-carbon power purchases with an emission factor of 0.0000 kg CO₂e/kWh.
Walking & Bicycle (Scope 3): Employee commuting and business travel emission factors with 0 kg CO₂e/km.
Useful for tracking and reporting low-carbon behaviours without excluding the activity altogether.
3. Renewable Electricity Supply Factors
Found in Scope 3 (Fuel and Energy Related Activities).
Includes “Electricity Supply – Renewables” factors for multiple countries.
These are set to 0.0000 kg CO₂e/kWh, representing renewable electricity sources.
4. Custom GHG Gas Entries
Direct entry factors for Methane (CH₄) and Nitrous Oxide (N₂O) are also available.
-
These have fixed conversion factors aligned to their Global Warming Potential (GWP):
CH₄: 28.0000 kg CO₂e per kg
N₂O: 265.0000 kg CO₂e per kg
Enables precise recording of non-CO₂ greenhouse gas emissions when specific data is available.
How use the Sumday Calculated emission factors
Enable the dataset for use in your assessment
Go to your Emission Assessment Settings (icon with 3 lines and 3 circles in the top right of the assessment).
Add Sumday Calculated to your Scope 3 activity datasets and Save changes.
Enter data using custom factors
In the Accounting tab, locate the relevant transaction.
Switch to an Activity-based calculation.
Choose Sumday Calculated and select the relevant factor (e.g., Direct CO₂/CO₂e Entry, Walking, Zero Emission Electricity).
Enter your data in the Quantity field.
Keep records clear
(Optional but recommended) Add a note to the entry (e.g., “Supplier provided footprint” or “Zero emission renewable electricity contract”) to support audits and transparency.
🔎 Tip: You can view all available Sumday Calculated factors by clicking the EF Database Table (spreadsheet icon, top right in Sumday) and searching for Sumday Calculated.
