9 June 2023 - Coalition Clean Baltic – CCB, the international network of environmental NGOs from the Baltic Sea Region, has condemned the unprecedented violence and aggression of Russia against Ukraine since the first day of this brutal war. It was obvious from its very beginning that, besides millions of human lives, nature will be severely damaged in any environmental compartment – land, water and air. Evidences of impacts were piling up and ranged from destruction of environmental infrastructure and contamination of soil to devastation of nature protected areas and extermination of flora and fauna.


On 6 June 2023, the dam of Kakhovka hydropower plant that was under control of Russian troops, was demolished, causing an immediate, uncontrolled and massive discharge of water from its reservoir, the biggest in Ukraine in terms of water volume. It has led to a large-scale man-made disaster across middle and lower Dnipro River catchment, the consequences of which will be felt for decades.


Besides catastrophic flooding of numerous settlements downstream with total population of tens of thousands of people, this accident will inevitably have severe environmental impacts affecting the area of over 5000 km2 both down- and upstream the destroyed dam. These foreseen impacts will include contamination of drinking water, flushing large volumes of polluted water and sediments into the Black Sea, death of large numbers of fish, waterfowls and benthic fauna, destruction of coastal habitats and numerous protected areas, changes in overall climate regime of the region. The lack of water supply upstream will have significant socio-economic consequences causing dehydration of the irrigation system of the agricultural sector in Kherson and Zaporizhzhia regions, shutdown of industrial enterprises, creating risks for cooling reactors of Zaporizhzhia nuclear power plant, largest in Europe.


It will have long-term and potentially even irreversible impacts for both Ukraine and for the European environment in general.


In support of our Ukrainian friends, members and partners, CCB urges the international community:


  • to appeal to your governments to condemn the actions of the Russian Federation causing yet another stage of a humanitarian catastrophe and act of ecocide;


  • to unite the efforts, capacities and competences in thorough investigation and evaluation of impacts of the Kakhovka dam demolition, as well as minimizing those;



Together, we have the power to change the course of events and make those responsible for this disaster liable. Let our voices be heard and our actions be an example of solidarity and responsibility towards nature and humanity.

EU Council decision on 2026 fishing limits fails to implement legally required safeguards, jeopardising the fragile marine ecosystem

3 October 2025 - Coalition Clean Baltic, together with its Member Organization BUND - Friends of the Earth Germany and the citizens’ initiative “ Lebensraum Vorpommern ”, have launched a petition to stop new oil and gas drilling projects in the Baltic Sea . The petition comes in response to plans to exploit a deposit just 6 km offshore Świnoujście , Poland, in the transboundary waters of the Oder Estuary and Pomeranian Bay. The planned site lies at the heart of NATURA 2000 protected areas , which are vital for biodiversity, climate action, and local communities. Oil and gas extraction in the Baltic Sea poses severe threats to its fragile ecosystems. Industrial activities such as drilling, pipeline construction, and ship traffic risk polluting the water with chemicals, oil leaks, and toxic waste. Underwater noise from pile driving and increased traffic would further degrade marine habitats. These pressures add to the already critical challenges faced by the Baltic Sea, including biodiversity loss, eutrophication, and the accelerating impacts of climate change. The consequences extend far beyond nature. Local communities rely on a clean and healthy Baltic for tourism, fishing, and quality of life. Expanding fossil fuel infrastructure would also undermine Europe’s climate commitments and lock in carbon emissions for decades to come. The petition calls on the Ministry of Climate and Environment of Poland, the Helsinki Commission (HELCOM), the European Commission, and the Secretariat of the Espoo Convention to : Stop the plans for oil and gas extraction in the Oder Estuary and the Pomeranian Bay; Ban any new oil and gas extraction across the Baltic Sea; Ensure strong cross-border cooperation and communication amongst all involved states. The petition is open through the WeMove Europe´s platform and can be signed here .
