Carbon calculations are only as reliable as the emission factors behind them, the figures that convert a litre of fuel or a kilowatt-hour of electricity into a CO2 equivalent number. These factors change over time as governments update their methodology and underlying data. This post explains how Enistic keeps its factor database accurate and current, so your figures stay correct year after year.
What Are Emission Factors?
An emission factor is a standardised figure published by a government or recognised body, for example DEFRA in the UK, that tells you how much carbon dioxide equivalent is produced per unit of a given activity, a litre of diesel, a kilowatt-hour of grid electricity, a tonne of a particular material. Every carbon calculation depends on applying the correct, current factor to the right activity data.
The Scale of the Database
Enistic maintains a database of over 40,000 UK and EU government approved conversion factors, covering fuel types, vehicle types, energy types, product composition, raw materials, and company-level annual emissions figures. This breadth matters because a business with multiple sites, vehicle types, and product lines needs many different factors applied correctly and consistently across the board.
How Updates Happen
Government bodies typically review and reissue emission factors annually, sometimes revising methodology as measurement improves or as national grid electricity mixes change. When an update is issued by the relevant authority, Enistic reviews the change and updates the factor in the platform promptly, so calculations going forward use the current figure rather than an outdated one.
Why This Matters For Your Reports
If a report used an outdated emission factor, the resulting figures would not reflect current best practice, and could be challenged under audit. Since factors update automatically within the platform rather than depending on someone remembering to check a spreadsheet, your reports are calculated against whatever is current at the time of submission.
Automatic updates handle the routine cases. Where a factor change is ambiguous, or where a specific activity does not map clearly to an existing factor, an in-house carbon consultant reviews it manually before it is applied to your data.

Why This Matters for Compliance
ESOS, SECR, and CSRD all expect emissions data calculated to a defensible, current standard. Enistic’s 11.7% audit rate, well below the roughly 33% industry average, reflects a platform where the underlying data has already been checked and kept current, not assembled at the last minute.
