Impact on climate change

Aalborg Portland is considered the biggest polluter in Denmark. The emissions of the industrial company in 2018 were equivalent to 2.2 million tons of CO₂, or 4% of the national CO₂ emissions. According to the Danish Economic Council, the cement industry does not have a sufficient economic interest to reduce its CO₂ emissions, because the price to pollute is too low. In 2022, Aalborg Portland announced a corporate roadmap that sets an emissions ceiling target of no more than 600,000 tons by 2030.
