This is a reduction from a maximum of 3.4 million tonnes of carbon dioxide per year in Preem's original application to 2.2 million tonnes in the new version, something that P4 West was the first to report.

The reasons for this are that the expansion is done in a different way, and that Preem plans to use technology to capture carbon dioxide.

Advanced technology

- Since our first application in 2016, a lot has happened. We then based on existing technology and how the business worked then, says Dani Backteg, Preem's head of press.

How should you go about reducing emissions?

"It's all about smart engineering solutions and carbon dioxide feedback is also being developed," says Dani Backteg, Press Manager at Preem.

The expansion, which is being done, among other things, to better handle the residual product heavy oil, has been approved by the Land and Environmental Court in Vänersborg. But the decision was appealed to the Land and Environmental Court, to which Preem will now submit a response letter, before 31 October.

Aroused debate

The estimated doubling of the refinery's carbon dioxide emissions has received a lot of criticism, which has led the government itself to try the case. A hearing will be held in the usual way in the high court at the beginning of next year, but the decision will be taken by the government.

How much has the debate on carbon dioxide emissions affected?

- Both a little and very much. We are very keen on doing the best in our business and do not want to be identified as the problem, says Dani Backteg, Preem's press manager.
