CMS grants the endangered Baltic Proper Harbour Porpoise the highest protection status following concerted action from NGOs

CCB • February 15, 2024

The common harbour porpoise is critically endangered in the central Baltic Sea and off the Iberian Peninsula, with only a few hundred individuals left. However, effective measures to enable the recovery of these special populations have so far been lacking. At the meeting of the UN Convention on Migratory Species (CMS COP14, 12-17 Feb 2024), the Baltic Proper harbour porpoise has now been included in Appendix I: This recognises this sub-population as critically endangered and emergency measures can be taken to save it. 

15 February 2024 (Joint Press Release) -
Whale and Dolphin Conservation, Humane Society International, Coalition Clean Baltic and ORCA made a decisive contribution to the decision. Last year, they submitted a joint report to CMS on the Concerted Action to call for stronger protections for the harbour porpoise populations in the Baltic Proper and off the Iberian Peninsula and to restore their habitats. As a result, the CMS member states of the EU submitted a proposal for the harbour porpoise to be included in Appendix I of the Convention, thereby granting it the highest protection status and enabling priority conservation measures to be taken. The uplisting has now been granted by CMS. The aim is to prevent, remove or mitigate obstacles to their seasonal migration and to control other factors that might endanger their survival. The main threats to the Baltic proper harbour porpoise include bycatch, underwater noise and pollution. 


"We are very pleased that the critical situation of these unique populations has been acknowledged; and we strongly encourage the countries around the Baltic Sea to take urgent action to ensure the survival of the only whale species native to the Baltic Sea", says Ida Carlén, formerly with the Coalition Clean Baltic, now Senior Policy Officer at the Swedish Society for Nature Conservation. 


"The uplisting of the Baltic Proper harbour porpoise to Appendix I of CMS is an important milestone that has been the result of years of hard work by NGOs. This positive outcome demonstrates the value and much-needed capacity that civil society can bring to international conservation objectives", says Ed Goodall, Head of intergovernmental engagement at WDC. 


The group of NGOs have long standing experience and have been working for decades in the development of marine conservation and policy, providing advice to governments and the EU as well as by raising awareness through campaigns and petitions. The uplisting of the Baltic Proper harbour porpoise to Appendix I of CMS is a further step forward in the implementation of effective conservation measures to protect this population.

Supporting information


The Harbour Porpoise is one of the smallest species within the larger family of whales, dolphins and porpoises. The genetically distinct Baltic Proper harbour porpoise sub-population is listed as Critically Endangered by IUCN as well as HELCOM, the regional seas convention in the Baltic Sea. There are only a few hundred individuals left in this population, which declined severely in the 1960-1970s due to being caught in fishing nets, particularly the highly deadly gillnet fisheries. They also suffer from high levels of toxic pollutants such as PCBs and dioxins. Due to ongoing pressure, the population has not recovered since.

 

Bycatch is the main threat to the only resident cetacean native to the Baltic Sea. However, environmental contaminants, underwater noise and the effects of climate change on the marine ecosystem, food availability and natural habitats also pose a threat to the harbour porpoise. 

 

In the process of the CMS Concerted Action, the NGO alliance of Whale and Dolphin Conservation (WDC), Humane Society International (HSI), Coalition Clean Baltic (CCB) and ORCA has also supported the so-called Jastarnia plan of ASCOBANS, a recovery plan for the Baltic harbour porpoise. This involves advising EU governments on measures to reduce bycatch. The NGOs maintain countries need to do much more to mitigate bycatch and implement and monitor effective conservation measures to help populations recover. 

 

The only survey on abundance and distribution of the Baltic Proper harbour porpoise was conducted by the SAMBAH project in 2011-2013. In 2024-2025 a second survey, SAMBAH II, will be conducted, which will be critical in assessing the current status of the population. 

 

WDC conducted an awareness-raising campaign for the Baltic Proper harbour porpoise with the aim of achieving a year-round ban on gillnets in marine protected areas. A petition with more than 100,000 signatures was submitted to the German government in September 2021. WDC also initiated an open letter to the German government, signed by more than 100 cetacean experts from around the world, calling for effective measures to protect the Baltic Proper harbour porpoise. WDC's educational work continues to this day. 

 

CCB and been engaged in awareness raising activities for the Baltic Proper harbour porpoise during this period, through a number of publications, press releases, events and educational activities. A CCB #SavetheBalticPorpoise petition was delivered to the EU Commissioner for Environment, Ocean and Fisheries, Virginijus Sinkevičius, in Helsinki, in November 2022 with over 120,000 signatures. Awareness raising and policy advocacy for this population remain as some of the main activities at CCB, with support of the Swedish Society for Nature Conservation (SSNC).

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).

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.
