FAQ
Can we add our own EPDs/LCAs as emission factors?
Chevron arrow down
Yes, customer-specific emission factors can be added any time upon request. Depending on the type of data and source, these can either be made available only for the requesting customer, or for all users in the system.
How many emission factors do you have?
Chevron arrow down
The CEMAsys platform has access to over 300,000 global emission factors from various scientific sources; including the EPA and DEFRA.
How often are your emission factors updated?

Most emission factors are updated annually, based on new available data. However, an assessment of the need for an update as well as availability of new data is made each year, which results in not all emission factors being updated annually. This is especially the case in some Scope 3 categories.
