Lynetteholm environmental impact projections based on 41-year-old research

Greenlighting the dumping of sludge in Køge Bay was partly based on US report involving canal dredging from 1981 

Since January, hundreds of thousands of tonnes of sludge has been dumped into Køge Bay as part of the massive Lynetteholm artificial island construction project. 

The issue came to prominence after attracting heavy criticism from the Swedish government, among others. 

Despite that, the Danish authorities continue to maintain that the dumping doesn’t affect the sea environment in the bay – referring to the project’s environmental impact report.

But now national broadcaster DR has uncovered how the report is based on, among other things, a 41-year-old article from the US.

“It’s based on a number of assumptions for which there is no immediate evidence, so it resembles speculation,” Karen Timmermann, a DTU Aqua professor, told DR.

Sticking to their guns
Timmermann’s conclusion is backed by several other Danish experts and the authors of the original US report, which pertains to the environmental impact of canal dredging in a number of US estuaries.

Fred Lee, one of the researchers behind the report, underlined that their method would require thorough investigations of local conditions in Køge Bay to be used as evidence. 

“We don’t understand how the orgnisation behind this project has used our data to reach the conclusion there is no significant environmental impact,” Lee told DR.

Despite the news, city developer By & Havn maintains that its environmental impact report is sound and that this was the best calculation procedure.

To add insult to injury, a heavy grey residue recently began washing up in Copenhagen waterfront areas, much to the disdain of local residents.

Generated by the construction of the dams needed to complete the first phase of the building work, when sand comes into contact with water, By & Havn has confirmed the foam is not toxic.

Nevertheless, locals are adamant they will no longer bathe in their local designated area.

    How internationals can benefit from joining trade unions

    Being part of a trade union is a long-established norm for Danes. But many internationals do not join unions – instead enduring workers’ rights violations. Find out how joining a union could benefit you, and how to go about it.

    Internationals are overrepresented in the lowest-paid fields of agriculture, transport, cleaning, hotels and restaurants, and construction – industries that classically lack collective agreements. A new analysis from the Workers’ Union’s Business Council suggests that internationals rarely join trade unions – but if they did, it would generate better industry standards.
