Public buses in Copenhagen and Frederiksberg have been polluting markedly less thanks to brand new filters that eliminate 95 percent of particulate matters and nitrogen dioxide.

Over the past six months, some 300 buses have been fitted with more efficient filtering systems that significantly contribute to cleaner air in the capital.

The cleaner buses operate, for instance, on the 1A, 2A and 6A routes, which run through some of the most congested and polluted zones in the city.

And although they have been in operation for less than six months, they have already driven over 3.5 million km.

The filters were mostly financed by the Environmental Protection Agency (EPA) that invested 74 million kroner into the project, while the City of Copenhagen and Frederiksberg Municipality contributed with 9 and 1 million kroner respectively.

Cleaner air initiatives
“In addition to cleaner buses, we have launched a scheme that focuses on scrapping some of the oldest and most polluting burners,” stated Michel Shilling, the deputy director at EPA.

“And we have also increased control efforts regarding shipping emissions, so that the air in the capital and in the rest of Denmark will be even cleaner.”

By reducing air pollution, the new buses will help to eliminate one of the most serious sources of lung cancer and respiratory diseases in the capital.
