Danish Government Bans Ship Scrubber Water Discharge by 2025

The Danish government has announced a ban on the discharge of scrubber water from ships into Danish territorial waters, effective July 1, 2025. Scrubbers are used by ships to comply with sulfur emission regulations, but their discharge can contain harmful substances like PAH chemicals, particulate matter, and heavy metals. The ban is expected to reduce discharges of these substances by up to 20 percent for nickel and 7 percent for anthracene, significantly benefiting the marine environment.

Environment Minister Magnus Heunicke highlighted the negative impact of scrubber water on the ocean’s ecosystems and food chains, emphasizing the need to end scrubber water pollution. Ships will be required to switch to low-sulfur fuel or closed scrubbers by 2025 or 2029 respectively, with the residual product from scrubbers to be delivered to port reception facilities. Denmark also aims to advocate for similar restrictions in the Baltic and North Seas through regional maritime conventions under the United Nations’ International Maritime Organization.

The ban on scrubber water discharge in Danish state waters reflects the government’s commitment to environmental protection and sustainability. By taking action to reduce harmful substances in the marine environment, Denmark seeks to promote healthier oceans and seafood, while also advocating for international regulations through the IMO. The new agreement establishes a timeline for transitioning to cleaner shipping practices, aligning with global efforts to minimize pollution from maritime activities.
