Coalition Clean Baltic expresses serious concerns regarding factual massive release of greenhouse gas and other possible environmental consequences of the natural gas leakages that were detected by Danish and Swedish authorities from the Nord Stream 1 and 2 pipelines on 27-28 September 2022.


With the information available at this point and risk assessment from EIA Reports of both pipelines, presented under the Espoo Convention consultations, the full volume of gas, being contained in the damaged pipelines may be released into marine environment and atmosphere.


In the worst case scenario, given pipeline dimensions in the project description (internal diameter 1,153 mm, length 1,220 km) the volume of one pipeline can be calculated as 1.27 million m3. At the settle out pressure of 165 bar, there will be the equivalent of 210 million m3 (at atmospheric pressure) or around 148,000 tons of gas in one enclosed pipeline. According to the EIA, the consequent environmental impacts can occur following the release of gas:


  • Emission of greenhouse gases to the atmosphere:
    Methane, equivalent to the release of 3.7 million tons of CO2 in terms of climate change potential
  • Impacts on water quality:
    Natural gas exhibits negligible solubility in water, and thus has little effect on water quality in the event of an underwater leak. The gas will rise to the water surface, from where it will be released into the atmosphere; the extent to which it dissipates depends on meteorological conditions and the weight of the gas in relation to the surrounding air. A short thermal impact (temperature drop to negative value caused by gas expansion, or Joule Thomson effect) may occur in the surrounding water. Another possible impact on water quality from an accidental pipeline rupture and gas release is a possible updraft of bottom water. This could cause bottom water to be mixed with surface water, with an impact on salinity, temperature and oxygen conditions.
  • Impacts on fish, marine mammals and birds:
    All marine organisms (benthic fauna, fish, marine mammals and birds) within the gas plume or the subsequent gas cloud will die or flee from the influenced area, which subsequently could impact the designation basis of protected areas (including Natura 2000 sites). The impact will be of limited time and space. 

Besides the expert assessment of higher than estimated in EIA climate impacts (up to 14.3 million tons of CO2-equivalent over a 100-year timeframe), the identified leaks are located in or near the only cod spawning area we have in the Eastern Baltic Sea. Hence the event can cause considerable harm/mortality to the young fish recently born in the area, as well as physical and physiological damage (incl. gas bubble disease), spatial disturbance, etc. To monitor the environmental consequences of this unprecedented situation, all EU Member States being HELCOM Contracting Parties in the area should swiftly deploy instruments to measure the status in relation to e.g. salinity, oxygen and pH. Such equipment could be placed around the perimeter of the incident areas to measure if methane leak has further away effects.

We also herewith inquire that a transparent information process should be established by respective EU Member States being HELCOM Contracting Parties to keep the public aware of environmental impacts of the accident and their implications for future environmental efforts as well as their consequences on climate and health of the Baltic Sea. Respective HELCOM subsidiary bodies, i.e. STATE & CONSERVATION, RESPONSE and PRESSURE should be involved.

Brussels, 30 March 2026 - Today, Fisheries Ministers from EU Member States meet with the European Commission for the AGRIFISH Council. On this occasion, Oceana, BLOOM, ClientEarth, Coalition Clean Baltic (CCB), Environmental Justice Foundation (EJF), Seas At Risk and WWF EU, handed a symbolic ''Pandora’s Box'' to the EU Commissioner Costas Kadis, sending a clear message as the European Commission prepares its 2026 evaluation of the Common Fisheries Policy (CFP). The box represents the risks of revising EU’s main fishery policy framework: once opened, competing demands from Member States, industry, small-scale fishers, and coastal communities could quickly spiral into division, regulatory delays and uncertainties. This would put at risk the hard-won progress made in restoring Europe’s fish populations and improving the profitability of the fishing sector. NGOs urge decision makers to build on the progress made to date and to prioritise the full and timely implementation of the existing rules. Reopening the CFP and its related provisions would undermine ocean health and the long-term future of Europe’s fishing communities. '' Europe's fisheries policy is facing a credibility test. The law is already there. The tools to rebuild our seas already exist. What's missing is the political will to deliver. Overfishing should have ended by 2020 at the latest. Reopening the CFP would signal that missed deadlines carry no consequences, erode trust, revert the progress made, and put the future of our fisheries and coastal communities at stake ’’, said the NGO coalition. *** Oceana: Vera Coelho, Executive Director and Vice President in Europe BLOOM: Claire Nouvian, Founder and General Director ClientEarth: John Condon, Lead of Marine Ecosystems Coalition Clean Baltic (CCB): Ida Carlén, Co-Chair Environmental Justice Foundation: Steve Trent, CEO/Founder Seas At Risk: Dr Monica Verbeek, Executive Director WWF EU: Ester Asin, Director

Uppsala, March 2026 - CCB has closely worked with the implementation of the EU Marine Strategy Framework Directive (MSFD) ever since its adoption and welcomed the opportunity to give feedback to this crucial directive for marine biodiversity and ocean health through the EU Call of Evidence . Evaluations conducted by the EU Commission previously found many positive effects for EU marine waters stemming from the directive, but also that the directive has some shortcomings. CCB however, maintains that the largest obstacle to fully implementing the directive and achieving Good Environmental Status (GES) is the lack of political will among Member States to do so. This forthcoming revision must therefore result in a framework directive that is more easily enforceable, measurable and implementable, accompanied by sufficient funding to carry out the measures. Furthermore, in order to achieve GES as fast as possible other key pieces of EU legislation must also support reaching it and focus on achieving the goals of the MSFD in their objectives. Seeing that European seas generally are in poor condition and under mounting pressure from human activities and that in the Baltic Sea the situation is especially dire there is an urgent need for truly ecosystem-based management of our seas and for reaching GES. The revised MSFD can help us achieve this, but only if it includes the points outlined below and the directive is fully and swiftly implemented: *** [Short version]*** Operationalise the overarching GES goal: EU sea areas were supposed to reach GES already in 2020, but due to low political ambition, sadly did not do so. Member States should therefore strive to reach GES as fast as possible now. Setting a new overall deadline for when to reach GES is not the answer on how to achieve this goal most efficiently, instead tools that address pressures and measure progress and ensure actual, timely implementation of ambitious measures must be included in the revised directive in order to operationalise achieving the overall GES goal. CCB therefore recommends making the existing and forthcoming threshold values for the descriptors and their criteria legally binding and part of the main directive. Improving regional coordination and implementation: To improve the coherence, coordination and effectiveness of MSFD implementation, assessment of GES, monitoring and the national PoMs the role of the Regional Seas Conventions (RSCs) must be clarified. CCB would welcome collating all the national PoMs into one regional PoM for the Baltic Sea, which should be aligned with, in addition to reaching the goals of the MSFD, with achieving the goals of the Baltic Sea Action Plan (BSAP). Land-sea interface: For the Baltic Sea to achieve GES it is key that land-based pressures, primarily nutrient runoff from agriculture causing severe eutrophication, is also addressed and that implementation of the MSFD goes hand in hand with the implementation of the Water Framework Directive (WFD). The goals of the MSFD and achieving GES should also be included when implementing and shaping the Common Agricultural Policy (CAP), as well as any synergies with implementing the EU Zero Pollution Action Plan which are also important to identify and utilise. The Baltic Sea also has a too high prevalence and level of other pollutants and hazardous substances affecting marine life. Fisheries and aquaculture: As one of the main pressure factors on the marine environment in general, as well as in the Baltic Sea, fisheries and aquaculture and the effects they have on the marine ecosystem and its biodiversity must be addressed in order to achieve GES. This is especially crucial when considering the MSFD descriptor for Biodiversity (D1), Fish and Shellfish (D3), Food webs (D4) and the one for Seabed integrity (D6). Climate change: Climate change is also affecting the Baltic Sea faster than other marine regions and must be factored in when managing the sea area and its resources to ensure EBM and the full implementation of the MSFD and achieving GES. The effects of the climate crisis should be accounted for when setting pressure reduction targets and threshold values for the descriptors and their criteria, in a way that when an effect cannot be measured nor predicted the precautionary principle must be used. Revising Art. 14 of the MSFD: Article 14 in the MSFD outlines the acceptable exceptions when reaching GES is not possible. The article needs to be revised in the forthcoming revision, since it contains too many and too broad in scope possibilities for exemptions (e.g. in Art. 14(4)), which jeopardise the implementation and fulfilment of the directive as a whole. A possible way of modifying it would be to introduce an obligation for Member States to demonstrate that they have taken all measures within their control nationally and that they have tried to address the problem and advance solving it on a regional level through cooperating with other Member States, before they can apply for a possible exemption. Make the Programme of Measures contain ambitious & concrete measures: One of the cornerstones of the MSFD is the national PoMs that are published every six years and are precluded by an assessment of GES in national waters and a monitoring programme. Unfortunately, the current approach to PoMs where Member States freely can choose measures has led to an overall too low level of ambition in the PoMs, and to large differences within regions and between neighboring countries in terms of which measures are included. In order to fully implement the directive and to achieve GES it is of paramount importance that the national PoMs have a high level of ambition and contain concrete, implementable measures and that there is regional coordination. Easing the reporting burden: One of the results from the evaluation of the MSFD was that the current reporting burden is considered to be too high and a possible way to address this is to align the reporting obligations of the MSFD to more reassemble those of the WFD, that has a more simplified 6-year cycle compared to the MSFD. The implementation cycle however should not be revised or at least not in a way that delays reaching GES. Improve coherence with other legislation: To ensure that the revised MSFD is fully implemented it is essential that coherence with other relevant legislation is improved. The MSPD (foundation for the forthcoming Ocean Act) is also currently being revised and to reach the goals for both the directives achieving GES needs to be a cornerstone of the Ocean Act. This is the only way to deliver truly ecosystem-based management of our seas, and the revision of both directives should therefore be coordinated and focused on achieving GES. CCB looks forward to continuing to provide input to the revision process of the MSFD as well as working with the implementation of the MSFD, especially in the Baltic Sea. CCB expects that the revision will result in a more enforceable directive that leads to the fast implementation of ambitious measures to improve the state of the Baltic and European Sea areas and to the achievement of GES.
