1. Recording the consumption of steam, heat and compressed air
To calculate emissions from steam, heat and compressed air, companies need to collect precise information on consumption. For steam and heat, this is usually done via invoices from the supplier or via meter data, for example from heat meters or steam meters in the company's own plant. As compressed air is usually generated on site, the electricity consumption of the compressors is the most important source of data. Alternatively, consumption values can also be estimated from operating times and compressor output.
Required activity data
The activity data required for this calculation includes:
- Consumption of steam, heat and/or compressed air: Collect data on the amount of steam, heat and/or compressed air consumed. The most common method is to use purchase records.
- The mass or volume of steam, heat and/or compressed air entering the facility: This data can be based on receipts, purchase records or data provided directly by the supplier and/or the customer's online portal.
2. Accounting for steam, heat and compressed air in the Climate Hub
Click on "+ Add own activity" to enter your steam, heat and compressed air consumption. This will open an input mask where you can enter the information step by step:
Entering district heating consumption involves several steps:
1. Name the activity
Enter a name for your activity in the field "Kind". This field is mandatory.
2. Market-based emissions factor
Indicate whether you have a market-based emissions factor.
If "Yes":
An entry form will open. Provide:
-
direct emissions factor and upstream factor for the market-based approach
-
unit of the factors (mandatory; selected via dropdown)
-
the source of the factor
-
optional: specify individual gases in the expanded section
If "No":
No market-based entry form will appear. Input continues directly in the location-based section.
In this case, the VERSO Climate Hub will calculate emissions solely using location-based factors – also for the market-based method.
Note: The unit dropdown in the location-based section will then be active, and unit selection is mandatory.
3. Location-based emissions factor
Provide:
-
direct emissions factor and upstream factor for the location-based approach
-
unit of the factors (via dropdown)
Note: If you previously selected "Yes" when asked about a market-based emission factor, the dropdown menu in this section is disabled and automatically adopts the unit from the market-based section.
If you selected "No", the dropdown menu is active here and selecting a unit is mandatory. -
the source of the factor
-
optional: individual gases and biogenic emissions in the expanded section
In the section "Required for ESRS E1-5", also specify:
-
whether the energy was self-generated
-
the share of renewable energy (%)
-
the share of nuclear energy (%)
This information is required for the E1-5 calculation (see point 4 under Energy consumption).
