A city councillor told newspaper Jyllands-Posten that the city, which has long stated its aim of becoming the world’s first CO2-neutral capital, would not meet that target as scheduled.

“I won’t need to stand there in 2025 and say ‘hurrah, we’re CO2 neutral’, because I know that CO2 will still be emitted (then),” elected representative Ninna Hedeager Olsen of the Copenhagen Municipality environment section told Jyllands-Posten.

Tourist board Visit Denmark has previously used the emissions goal to market the city, while Prime Minister Mette Frederiksen named the target during the C40 climate summit when it was hosted by Copenhagen in 2019.

But the municipality has included wind energy produced in other municipalities in its calculations on energy sustainability, according to the newspaper report.

This means it effectively still emits CO2 overall.

The company which supplies energy to the city, Hofor, has erected windmills in a number of municipalities outside of Copenhagen. But the electricity produced by these windmills has been used in calculations of CO2 emissions in both Copenhagen and in the municipalities in which the windmills are actually located.

The replication of the energy production in data for different locations can “rightly” be said to be “cheating the scales”, according to Hedeager Olsen.

But that is not the only problem in calculations of the city’s emissions, she also admitted.

“There are loads of things that haven’t been counted,” she said.

The goal to become climate neutral by 2025 was first set by the city in 2012 in a climate plan adopted by the city government.

Copenhagen was the following year awarded the Cities Climate Leadership award for the plan.
