The Copenhagen City Council on Tuesday is expected to approve a vote to divest the city’s investment fund, worth 6.9 billion kroner, or roughly $1 billion USD, from all its fossil fuels holdings.

If the vote passes, the Danish capital will sell off its stocks and bonds in coal, oil, and gas in its continued effort to become “the world’s first CO2-neutral capital by 2025,” Mayor Frank Jensen told local media.

The exact amount the city has invested in fossil fuels has not been made publicly available, but reporting indicates the divestment would cost approximately 1 million kroner in fees to execute.

“Copenhagen is at the forefront of the world’s big cities in the green transition… Therefore it seems totally inappropriate for the city to still be investing in oil, coal and gas,” Jensen said. “We need to change that and I think this will sit will with Copenhageners’ desire for a green profile for their city.”
