Coalition Clean Baltic urges Danish authorities to stop the construction of Lynetteholm island

Coalition Clean Baltic • September 26, 2023

Coalition Clean Baltic calls to stop the Lynetteholm project that may result in environmental disaster in the Baltic Sea.

September 2023 - In 2021 the majority of the Danish Parliament adopted a Construction Act which allowed the constructor By & Havn and the Ministry of Transport to start the Lynetteholm project: an artificial peninsula in the Copenhagen harbour as a new district area in the city, that will house 35,000 residents and 35,000 workplaces. This project was approved despite Swedish criticism and without consultation of all the Baltic Sea countries.


In the same year, an Executive Order was introduced, nullifying the environmental laws in place and preventing complains. The only way for citizens, municipalities and associations to be heard is to raise a case in the national courts.


Environmental issues

The construction of this artificial island may block the flow of salt, oxygen-rich water into the Baltic Sea. The result of the Lynetteholm project can have significant, irreversible, negative environmental consequences for the Baltic Sea. Even minimal changes in the water flow into the Baltic Sea may affect the entire marine environment of all the countries around the Baltic Sea.

Regardless of the consultation responses, the ongoing Espoo negotiations with Sweden and the Climate Movement´s lawsuit, the construction of Lynetteholm continues.


Citizens and NGOs actions to stop the project

In 2021, Coalition Clean Baltic (CCB) called to postpone the the adoption of the Lynetteholm project through a letter sent to the Danish authorities, which was also shared with the European Commissioner for the Environment, Oceans and Fisheries , as well as with Directors General of respective DG of the European Commission and the Chair of the Baltic Sea Parliamentary Conference.


In 2022 Coalition Clean Baltic (CCB) signed another letter, together with other 16 NGOs, to complain to the EU about Lynetteholm blocking water flow.


In 2023 updated information were published about the Lynetteholm project. This document  contains the most updated information including those deliberations that have happened namely that:


  • updates about the Danish Climate Movement´s lawsuit;
  • the report of the 'professional reference group’ set by Transport Agency with four independent professors (Prof. Katarina Elofsson, Department of Environmental Science, Aarhus University; Prof. Lone Kørnøv, Department of Planning, Aalborg University; Prof. Stiig Markager, Department of Ecoscience, Aarhus University; Prof. Thorbjørn Joest Andersen, Department of Geosciences and Nature Management, University of Copenhagen) released on 5 March 2023 which states that “blocking effects are cross border and can potentially affect the entire Baltic Sea. One consideration might be to change the design of the project, so that the outermost part does not include Kongedybet”. Individual opinion of Prof. Stiig Markager is i.a. that “the calculations carried out by DHI are not sufficient to reject a significant effect on the salinity in the Baltic Sea. This effect can occur throughout the Baltic Sea and will thus affect all countries around the Baltic Sea. Furthermore, any effect on the stability of the Baltic Sea's water column will produce derivative effects that can accumulate over time and potentially affect salinity beyond the immediate effect on salt transport”. According to Prof. Markager, the implementation of the project in its current state will have significant negative impact on environmental status of the Baltic Sea, hence also constituting a violation of the EU MSFD;
  • the supplemented EIA report for the project changes in the Lynetteholm project was released for public consultation until 8 May 2023;
  • the completion of the Espoo Convention transboundary consultation process is unknown.


In addition, in March 2023 CCB shared its concern to the Helsinki Commission (HELCOM) regarding the Lynetteholm project and submitted documents to the Informal consultation session of the Helsinki Commission (IC HELCOM 1-2023). In June 2023 CCB submitted new documents to the Informal consultation session of the Helsinki Commission (IC HOD 3-2023).


The consultation on the Lynetteholm project by all Baltic Sea countries is a legal duty incumbent on Danish authorities. Until all affected countries and organisations are consulted we call to immediately stop the Lynetteholm project. 

COP30 brings ocean and water to the center of climate policy

By CCB • December 5, 2025
In Belém, in the heart of the Amazon, the 2025 UN Climate Change Conference COP30 immediately set the bar high. In his opening speech, Brazilian President Lula da Silva stressed that climate change is no longer a "threat to the future", but a tragedy that the world is already experiencing here and now, and called on countries to accelerate actions rather than limit themselves to promises. However, as is often the case in COP meetings, the political reality turned out to be more complicated than ambitions. Negotiations were difficult: the countries could not agree on a clear and binding plan to phase out fossil fuels. It is important to note that the Global Action Plan has provided a platform for discussing the development of a roadmap for phasing out fossil fuels, the main driver of climate change. At the same time, COP30 has brought tangible progress in other areas: the countries agreed to triple the amount of adaptation funding for developing countries by 2035, strengthened the forest and ocean agenda, and expanded the range of practical initiatives under the Action Agenda . COP30 consolidated the trend: from "water at the center of the climate crisis" to a holistic ocean agenda closely related to energy, food, biodiversity and sustainable coastal development. From the COP29 Water Declaration to the COP30 Enhanced Ocean Water Program At COP29 in Baku, the Declaration on Water for Climate Action was adopted , with the aim to applying comprehensive approaches to combating the causes and consequences of climate change for water basins, emphasizing also the need to integrate water-related mitigation and adaptation measures into national climate policies, including Nationally Determined Contributions (NDCs) and National Adaptation Plans (NAPs). COP30 did not reverse this logic, but expanded it towards the ocean and coasts. Both processes "aquatic" and "oceanic" are moving in the same direction: integration of water, coasts and ocean into the climate plans of countries; development of nature-based solutions; strengthening transboundary management of water and marine systems; recognizing adaptation as an equal part of climate policy, rather than an "adjunct" to emissions reduction. Task Force on Oceans and the Blue NDC Challenge The international Task Force on Oceans , led by Brazil and France, was officially presented at the high-level ministerial meeting "From Ambition to Implementation: Delivering on Ocean Commitments" on 18 November, integrating oceans into a global mechanism to accelerate the incorporation of marine solutions into national climate plans. The Blue Nationally Determined Contributions (NDC) Challenge encourages countries to set ocean protection targets when updating their NDCs. The goal is to transition the Blue NDC Challenge into an Implementation Task Force. Members of the Blue NDC Challenge, currently 17 countries, can adopt a broad set of actions aimed at the protection and sustainable use of the oceans.These measures include the sustainable management, conservation, and restoration of coastal and marine ecosystems, supported by tools such as marine spatial planning, integrated coastal zone management, and climate-aligned marine protected areas. Countries are also encouraged to support sustainable and climate-resilient fishing and aquaculture, ensuring ocean health and long-term food security. B razil has set a clear example: its updated NDC includes a separate chapter on the ocean and coastal zones. For the first time, the national climate plan (Plano Clima) until 2035 includes a thematic adaptation plan for these areas. Priorities include the completion of national Maritime Spatial Planning (MSP) by 2030 and major programs for the conservation and restoration of mangroves and coral reefs (ProManguezal, ProCoral).

Pathway to Tox-Free Living: Policy and Action

By CCB • November 24, 2025
Leading scientists, consumer advocates and policymakers gathered on November, 18th in Brussels for the conference "From Evidence to Policy: Toward a Tox free Living Environment" . They warned that exposure to Endocrine Disrupting Chemicals in homes and consumer products represents a silent but severe public health and economic crisis. New findings presented to over 65 participants by the EU Baltic Sea Interreg project NonHazCity3 , LIFE ChemBee and the ToxFree LIFE for All projects as well as revealed widespread contamination of European households by complex chemical mixtures of hormone system disrupting substances (so called endocrine disrupters – EDCs) that contribute to chronic disease and impose enormous health costs. According to the key note speaker Dr. Aleksandra Rutkowska, the home environment is a significant source of exposure to EDCs through indoor air, dust and daily contact with common products. Current research links such exposure to a shocking amount of lifestyle diseases including 22 cancer outcomes, 18 metabolic disorder outcomes and 17 cardiovascular disease outcomes. Scientists also stressed that the crisis spans generations. EDCs trigger epigenetic changes that not only affect today’s population but also future children and even grandchildren. Other effects include reproduction disorders. Over the last decade, 150 million babies were born preterm, and evidence shows that reducing the use of plastics by half could cut the risk of preterm birth by half as well.
