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.
Activity data required
The activity data required for this calculation includes the amount of electricity consumed for the company:
- Electricity consumption: Collect data on the amount of electricity. The most common method is to use purchase records.
- Purchase records: The mass or volume of electricity entering the facility. This data can be based on receipts, purchase records or data provided directly by the energy supplier and/or the customer's online portal.
Balancing steam, heat and compressed air in the Climate Hub
No predefined activities have been created in the Other (steam, heat, compressed air) area. You can add your own factors if required. If the emission factors are known, you should always use the market-based and location-based approach. For both methods, you must specify whether the energy was self-generated and what percentage of the energy is renewable or nuclear.
