Two Swedish cement plants underreported 348,000 tonnes of CO2

Two Heidelberg Materials cement plants in Sweden underreported about 348,000 tonnes of fossil carbon dioxide between 2014 and 2023, the Swedish Environmental Protection Agency said on Wednesday.

The company reported too high a share of biogenic material in plastic fuel burned at its Slite and Skövde plants. After requesting more detailed calculations, the environment agency revised the fossil-emissions figures for the ten-year period.
Heidelberg must now surrender about 348,000 additional allowances under the EU emissions-trading system. The authority has also referred the case to prosecutors for investigation, which it says is routine when reporting errors are found.
The company told SVT that the calculation method had been approved but applied incorrectly, and that external audits did not catch the error. It said an accumulated surplus of allowances would cover the correction. Slite emits about 1.5 to 1.8 million tonnes of CO2 a year and is among Sweden’s largest industrial emitters.
