Denmark is managing various marine and aquatic environmental initiatives and challenges. DTU Aqua has expanded its research and education efforts, including a partnership to develop a new marine observatory at Middelgrundsfort in Copenhagen, scheduled to run through 2029. Additionally, the DTU Hirtshals Campus has increased its enrollment in sustainable fisheries and aquaculture programs.

However, environmental pressures persist. Reports indicate declining fish stocks and species diversity in Danish and Baltic waters, with cod populations under significant stress and the rise of invasive species. Concurrently, agricultural pollution remains a concern, highlighted by repeated enforcement actions against a farm in Tønder Municipality for silage juice leaks into local streams.
