HELCOM has recently joined the EMERGE project on shipping emissions in EU marine waters and was one of the 18 project partner organizations that attended its kick-off meeting in Laxenburg near Vienna, Austria from 24 to 26 February 2020.
Coordinated by the Finnish Meteorological Institute, EMERGE will quantify and evaluate the effects of potential emission reduction solutions for shipping in Europe, and develop effective strategies and measures to reduce the environmental impacts of shipping.
“Beyond producing data, the project will also develop several scenarios to help identify management options on how to best deal with all sorts of shipping emissions,” said Joni Kaitaranta, the HELCOM data coordinator handling the project at HELCOM. The outcomes of the project are expected to be further considered by the relevant HELCOM working groups.
As a project partner, HELCOM will mainly be involved in the work packages on hosting and publicizing spatial data outputs such as emission maps stemming from developed modelling framework and based on different management scenarios. HELCOM will furthermore participate in developing online tools for disseminating the outcomes and associated data to stakeholders, decision-makers and to the general public.
HELCOM has extensive experience in gathering and processing data on the marine environment and maritime activities, notably through its indicator work and its map and data service.
EMERGE will systematically analyze the complex interactions between technological options, pollutant emissions and dispersion, and environment. It will carry out measurements and modelling on actual vessels, along main shipping routes and in sensitive European marine regions.
Measurements will focus on abatement techniques and will include emissions to, and concentrations in water, air and marine biota. EMERGE will especially investigate how effectively available scrubbers reduce the effects of key pollutants.
For those who wonder why Laxenburg was chosen as the kick-off venue: besides hosting the premises of project partner IIASA where the event took place, the city is also (almost) the geographical centre of the project, effectively reducing CO2 travel emissions by the participants that were coming from all parts of Europe – ranging from the Baltic Sea to the Mediterranean.
Actions for a healthier Baltic Sea and HELCOM’s Voluntary Commitments to the UN Ocean Conference 2020 were addressed in Helsinki during the Annual Meeting of the Helsinki Commission – the 41st Meeting of the Baltic Marine Environment Protection Commission (HELCOM 41-2020) – that took place from 4 to 5 March 2020.
The Baltic Sea Action Plan (BSAP) and its update were one of the central themes of the event that also featured a high-level segment attended by high-level representatives such as state secretaries and other high-ranking ministerial representatives of the Baltic Sea countries and the EU. Only Ministerial Meetings rank higher on the HELCOM meeting scale.
“Building on the political will expressed by the ministers in 2018, we are now progressing from words to action, as 2019 marked the beginning of more concrete work on the new BSAP,” said Rüdiger Strempel, the Executive Secretary of HELCOM, in his statement.
Initially set to achieve its objectives by 2021, the BSAP is due to be updated in 2021 as mandated by the HELCOM Contracting Parties during the Ministerial Meeting held in Brussels in 2018. The past months were characterized by translating the political will expressed in 2018 into a concrete roadmap and actions towards the update, such as the analysis of sufficiency of existing measures.
In Helsinki, the high-level representatives recognized that clear progress has been made under the current BSAP during the past 13 years. However, they also acknowledged that the level of implementation has not been fully satisfactory and stressed the need to ensure and accelerate the implementation of the actions under both the current and updated BSAP.
Nevertheless, the BSAP remains one of the most effective instruments for a healthy Baltic, offering a long-term vision and strategic orientation, as well as a wide array of science-based actions and measures. The updated BSAP is expected to include considerations on climate change, marine litter, pharmaceuticals, underwater noise, and loss of and disturbance to the seabed, among other pressures.
At HELCOM 41-2020, the representatives particularly highlighted the importance of recognizing climate change as a cross-cutting topic and the need for more knowledge on the impacts and consequence of climate change, therefore regarding the BSAP as an “instrument to strengthen the resilience of the Baltic Sea ecosystem and minimize negative effects of climate change on society,” as stated in the meeting outcome.
Based on the existing plan, the update will maintain at least the same level of ambition as the current plan and include all actions and measures from that plan that have not been implemented yet.
The outcome of the HELCOM Stakeholder Conference 2020, held the day before HELCOM 41 and aimed at gathering input from stakeholders on the BSAP update and that was, was also presented during the session of the high-level representatives who particularly lauded the quality of the engagement of the stakeholders. A total of 49 potentially new BSAP actions were proposed during the event.
Furthermore, at HELCOM 41-2020, the representatives agreed on submitting five Voluntary Commitments by HELCOM to the 2020 UN Ocean Conference, concurring on:
updating of the Baltic Sea Action Plan by 2021,
the development of a HELCOM Science Agenda to contribute to the UN Decade of Ocean Science,
strengthening cooperation with other Regional Seas Organisations,
offering strong support for global efforts to address the marine litter problem on a global level, and
organizing a workshop on ecosystem-based management in support of the UN Decade of Ocean Science.
The voluntary commitments are part of HELCOM’s concrete efforts on global outreach and on advancing the global ocean agenda.
During the meeting, a number of HELCOM Recommendations were also adopted or revised by the Contracting Parties, such as the Recommendation on Deep-Sea Pilotage in the Baltic Sea (Recommendation 41/1) and the HELCOM Recommendation on the use of national manure standards (adopted in principle).
A roadmap on the collection of fisheries data to assess incidental bycatches and fisheries impact on benthic biotopes in the Baltic Sea was also agreed on during the meeting, as was the project proposal on the monitoring of pollution loads to the Baltic Sea (PLC-8).
Jochen Flasbarth, State Secretary at the German Federal Ministry for Environment, Nature Conservation and Nuclear Safety, with Rüdiger Strempel, HELCOM’s Executive Secretary. Germany will assume the chair of HELCOM from 1 July 2020 until 30 June 2022, taking over from Finland.
HELCOM 41-2020 also saw the nomination by Germany of Lilian Busse, Head of the Division of Environmental Health and Protection of Ecosystems of the German Environment Agency, as Chair of the upcoming German chairmanship. Germany will take over from Finland on 1 July 2020, for a period of two years.
The representatives further took note of Germany’s will to increase the political visibility of HELCOM work during its chairmanship, with the BSAP being at the centre of the work, further supporting the Parties in its implementation, and extending invitations to civil society and stakeholders to participate in HELCOM processes.
The high-level segment of HELCOM 41-2020 was attended by Katrine Nissen (Denmark), Harry Liiv (Estonia), Veronica Manfredi (EU), Terhi Lehtonen (Finland), Jochen Flasbarth (Germany), Silvija Nora Kalnins (Latvia), Vitalijus Auglys (Lithuania), Katarzyna Krzywda (Poland), Nuritdin Inamov (Russia) and Gunvor G. Eriksson (Sweden).
Concrete actions for a healthier Baltic Sea were proposed in Helsinki this week during the HELCOM Stakeholder Conference 2020 that aimed at gathering feedback from stakeholders on the Baltic Sea Action Plan (BSAP), HELCOM’s strategic programme of actions, which is due to be updated by 2021.
A total of 49 new actions to be considered for inclusion in the updated BSAP were voiced during the conference, touching upon a variety of topics such as hazardous substances, marine litter, shipping and other sea-based activities, as well as eutrophication and biodiversity.
Climate change was also heavily emphasized during the conference, as was the issue of implementation of BSAP actions at the national level, where stakeholders felt more progress should be made. Better collaboration between ministries and authorities also featured highly on the participants’ wish list, along breaking “thinking in silos” in favour of a more holistic view of protection of the marine environment of the Baltic Sea.
The conference, titled “For a sustainable Baltic Sea: The Baltic Sea Action Plan beyond 2021”, and that attracted over 120 participants from different organisations such as governments, NGOs, academia and industry, was a direct result of the decision recorded in the HELCOM Ministerial Declaration 2018 to include stakeholders in the BSAP update process.
According to the declaration, the BSAP update should “be strongly communicated with stakeholders, enable knowledge sharing between science and policy across all levels, be developed in a participatory and transparent way at the regional and local levels, including all appropriate stakeholders.”
Although its environmental objective to each good environmental status by 2021 is unlikely to be achieved, the BSAP remains one of the most effective instruments for a healthy Baltic.
“No other plan or programme offers the same long-term vision and strategic orientation, the same agreement on a holistic set of science-based actions and measures for a healthy Baltic Sea, the same regional and cross-sectoral acceptance,” said Rüdiger Strempel, the Executive Secretary of HELCOM, during the conference.
It is expected that the update of the BSAP will include considerations on climate change, marine litter, pharmaceuticals, underwater noise, and loss and disturbance of seabed, among other pressures. Based on the existing plan, the update will maintain at least the same level of ambition and include all actions and measures from that plan that have not been implemented yet.
The proposed actions gathered from the Stakeholder Conference will now be forwarded to the relevant HELCOM working groups for further consideration and possible additional development within HELCOM and the BSAP update processes.
In a bid to address the Baltic Sea’s eutrophication problem, about 40 experts on agriculture and wastewater attended a workshop in Helsinki last week to elaborate concrete actions and measures under HELCOM’s Nutrient Recycling Strategy.
“The aim of the [Nutrient Recycling Strategy] is to make better use of the nutrients already available [such as manure] and to reduce the [introduction] of new mineral nutrients into the cycle,” said Sari Luostarinen, the Chair of HELCOM Agri Group dealing with sustainable agricultural practices.
In 2018, the HELCOM members agreed, at the Ministerial level, to elaborate a Baltic Sea Regional Nutrient Recycling Strategy by 2020. Its objective is to reduce nutrient loading to the Baltic Sea by avoiding nutrient runoff by circulating the nutrients within the food chain.
“Agriculture remains a large source of nitrogen and phosphorus runoff to the sea,” said Susanna Kaasinen, HELCOM’s expert on agriculture and nutrients. According to the results of the recent State of the Baltic Sea report, 97 % of the Baltic Sea area suffers from eutrophication, mainly caused by excessive nutrient loading stemming from agriculture.
In Helsinki, during the workshop on nutrient recycling measures, the experts came up with a large variety of possible ideas for measures and actions which will now be considered by the HELCOM Agri and Pressure groups.
“The vision and objectives of the Nutrient Recycling Strategy were already defined in 2019,” said Kaasinen. “Now is the time to translate these into concrete actions and measures,” she said, adding that some of the proposals from the workshop could also be used for the updated Baltic Sea Action Plan (BSAP).
The BSAP is due to be updated by 2021 and is expected to heavily focus on eutrophication, among biodiversity, hazardous substances and litter, and sea-based activities.
Sea trout are reproducing again in parts of the Smeltalė river in Lithuania after a successful restoration exercise under the Baltic-wide RETROUT project.
“We counted 13 new sea trout nests within only two months after the restoration work was finished,” said Nerijus Nika from Klaipeda University, one of the partners responsible for the Lithuanian river restorations within RETROUT, further noting that the specifically created reproduction sections, or spawning habitats, were all intensively used by sea trout. The restoration work was completed in September 2019.
RETROUT carries out a number of river restoration demonstration cases in the project partner countries to improve the condition of sea trout populations.
“For viable and healthy sea trout populations, we need healthy and accessible rivers. Unfortunately, many rivers potentially suitable for sea trout aren’t yet in the condition we’d like them to be,” said Henri Jokinen, the RETROUT project manager at HELCOM.
In Lithuania, the rehabilitation started with the creation of a system of meandering shallow ponds in an area of the Smeltalė river previously purposed as a surface flow treatment wetland for improved water quality.
Since its construction 20 years ago, the wetland hadn’t been maintained, accumulating excessive sediments from defaulting sedimentation ponds as well as suffering from excessive vegetation on its banks.
In addition, a 500 m section was modified in the Smeltaitė stream, a main tributary of Smeltalė river, using stones, gravel and logs to create three 50 m long spawning and juvenile rearing habitats.
“According to local experts, such habitats are spawning hot spots for salmonids and lampreys in lowland streams of Lithuania,” said Jokinen. Indeed, all three created spawning habitat sections were intensively used by sea trout only two months after completion.
In the Smeltaitė stream, the two biggest trout nests – of 7,5 m2 and 10 m2 – were found in the restored stretch, in habitats pre-evaluated to be of high priority for sea trout females. One of these sites was constantly occupied for 1.5 month by up to five different trout, a rather unusual spawning behaviour.
With special focus on sea trout, the RETROUT project seeks to promote and develop sustainable coastal fishing tourism in the Baltic Sea region. RETROUT initiated 15 restoration cases in coastal rivers of Estonia, Lithuania, Latvia, Poland and Sweden. Measures under the project cover fishways, biotope restorations, water quality improvement, and dam removal plans.
In the RETROUT project, HELCOM leads the work package on Assessment of status and management of sea trout rivers and stocks which focuses mainly on the ecological aspect of trout fishing, notably through assessing fish stock and river habitat status, and by evaluating river restoration practices to improve trout populations.
The main results will be published as an assessment report and as a toolbox of best practices and guidelines for river restoration in the Baltic Sea.
“In addition to improving the actual condition of a river, the experience we get from these demonstration cases will help us to develop the ‘Guidelines for river restoration best practices in the Baltic Sea region,’ another major outcome of the project,” said Jokinen.
The restoration of the Smeltalė river was conducted by the Klaipeda District Municipality Administration, with technical and scientific support from the Klaipeda University.
“I was surprised by the large amount of existing research and projects in the Baltic Sea,” said Aaron Vuola, the HELCOM project coordinator in FanpLESStic-sea who led the publication, adding that it shows how pressing the issue of microplastics is in the region.
The review, for which a summary for policy makers is also available, establishes a comprehensive baseline on the existing policies related to microplastics on global, Baltic Sea, EU, and national levels. The report also showcases some of the existing research on microplastics at these various levels.
“This review confirms the need for harmonized monitoring methods if we want to be able to compare studies between regions and different matrices, or establish baselines for current microplastic levels,” said Vuola.
According to the report, the lack of commonly agreed methodologies for monitoring, sampling and analyses of microplastics is a major concern and calls for urgent need for harmonized, cost-efficient, and sufficiently robust monitoring methodologies for microplastics.
Currently, microplastics are not directly addressed through any global instrument even though several existing instruments cover some aspects related to marine litter and hence microplastics. However, the European Union is working towards restricting the use of intentionally added microplastic particles to consumer or professional use products.
Also highlighted by the report are the impacts of microplastics on humans through food chain or other means, still largely unknown and calling for more research.
“There is already lot of evidence of the negative impacts of microplastics to support the need for global, EU and national level regulation, but we also have to reduce the plastic use in general and address the problematic products in earlier phase of their life-cycle before they become marine litter and microplastics,” said Vuola.
In addition to providing an overview of the regulatory framework and useful information on topics such as sources and types of microplastics, the report can be used as a database for large amount of concluded research on various topics around the issue of microplastics.

Aren’t nutrients supposed to be good? What’s wrong with nutrients?
Nutrients are vital for humans, animals and the environment as a whole. They are also vital for agriculture and food production. No crops can grow without nutrients. But as with most other compounds, too much in the wrong place causes problems. In our region for instance, the excess of nutrients has led to the eutrophication of the Baltic Sea.
In terms of eutrophication and nutrients, what is the current status in the Baltic Sea region?
The Baltic Sea is a vulnerable sea for many reasons. The nutrients it has received in the past are bound in the sediments and released under certain conditions, causing internal nutrient loading. At the same time, nutrient runoff from current human activities is adding to the problem. Of the latter, many point sources have been reduced, for example due to improved wastewater treatment. But it is more difficult to restrict diffuse loading such as from agriculture. Depending on the weather conditions and due to increasing temperatures, eutrophication and its consequences are worsening. More actions to control the nutrient load are needed.
In general, what would need to be done to curb eutrophication and nutrient inputs, especially in regard to agriculture?
As said, crops cannot grow without nutrients. Both phosphorus and nitrogen need to be available for crops on the fields to achieve good yields. Good yields also mean that most nutrients given as fertilizers end up in the harvested crop and little is lost to the environment. The amount of nutrients spread as fertilizers should be adequate, for instance adjusting quantities depending on the crop, the soil type and its nutrient content, as well as the timing of the spread. The use of animal manure as a fertilizer is the traditional way to recycle nutrients in food production. However, due to segregation of animal and crop production it may be either available in excess or in deficit depending on the region. More precise utilisation of manure nutrients, including replacing mineral fertilization with manure, is important for reducing agricultural nutrient load. Also, other measures, such as reduced tillage, catch crops, water protection zones, are also needed to manage nutrient losses.
What concrete steps is HELCOM currently taking on the nutrient issue from the agriculture perspective?
HELCOM is efficiently driving several measures to reduce agricultural nutrient losses to the Baltic Sea. As an example, HELCOM is preparing the introduction of recommendations for national manure standards. The aim is to ensure the availability of updated, scientifically proven data on manure quantities and nutrient contents in the Baltic Sea countries so that the manure data used in fertilization planning and thus the amount of manure spread on fields becomes more precise. This is expected to reduce nutrient runoff from the fields. Furthermore, on resource efficiency, HELCOM is also preparing a strategy for nutrient recycling in the Baltic Sea Region. Again, the aim is to introduce more efficient measures to make better use of the nutrients already available and to reduce the need to introduce new mineral nutrients into the cycle. For example, this could be achieved by processing manure, different wastes and their by-products into recycled fertilizers.

Overall, what’s the current state of the management of wastewater from ships in the Baltic Sea, also compared to other seas?
The Baltic Sea is a highly sensitive sea area and eutrophication is one of its major problems. Therefore, following a lengthy preparation process within HELCOM, the International Maritime Organization (IMO) designated the Baltic Sea as “Special Area for sewage discharges from passenger ships under Annex IV of the MARPOL Convention.” Worldwide, it is the only region so far regulating these discharges.
The more stringent Special Area regulations, which already applies to newly built vessels, require passenger ships to either discharge their sewage into port reception facilities (PRF) or to treat sewage with an advanced on-board sewage treatment plant capable of reducing nutrients to a safe level for discharging at sea.
This is an important step forward towards a healthier Baltic Sea, while, at the same time, showing how a MARPOL Annex IV Special Area may be implemented.
Why the Technical Guidance? What’s its objective, background?
Handling big volumes of sewage in ports requires new and innovative approaches. Initial experiences show that there is no “one size fits all” solution. Almost each port, with its own, specific infrastructure requirements, needs a tailored solution.
The Technical Guidance sets out probable problems a port may encounter, and presents possible solutions on the different aspects of the management of wastewater from ships, be they of infrastructural or technological nature, or related to planning and communication.
Who is the Technical Guidance meant for?
The Technical Guidance offers recommendations to port operators and shipping companies. It can also be useful for administrations and municipal wastewater companies dealing with the issue.
How do you expect the Technical Guidance to improve wastewater management in the Baltic Sea?
The Technical Guidance will hopefully aid all involved stakeholders to better understand the major and various challenges ports and ships face when it comes to managing wastewater. Awareness and good communication is a first step in working together on practical solutions, and ultimately, on improving the environment of the Baltic Sea.
Intended for shipowners, port operators, local administrations as well as municipal wastewater companies, the Technical Guidance was developed to facilitate the management of wastewater from ships to better comply with IMO regulations on wastewater handling in the Baltic Sea region.
In 2011, the IMO designated the Baltic Sea a Special Area for sewage discharges from passenger ships, directing passenger ships operating in the Baltic Sea and not equipped with an on-board sewage treatment facility to discharge their sewage – or black water – at port, in a so-called port reception facility (PRF).
“Initial experiences show that there is no ‘one size fits all’ solution,” said Susanne Heitmüller, the Chair of HELCOM Maritime, the HELCOM working group that deals with shipping-related topics. “Almost each port, with its own, specific infrastructure requirements, needs a tailored solution,” she added.
The current lack of experience with sewage handling in ports requires the development of new and innovative approaches to manage these new challenges. The Technical Guidance for the handling of wastewater in ports was produced to fill this gap and offer a wide range of possible options to several scenarios ships and ports may face.
“The Technical Guidance sets out probable problems a port may encounter, and presents possible solutions on the different aspects of the management of wastewater from ships,” said Heitmüller.
Under the IMO regulations, all newly built passenger ships after June 2019 are required to comply to stricter rules on wastewater discharges, while older passenger ships will have to comply to the same rules by June 2021, with some exceptions until June 2023 for ships en route directly to or from a port located outside the Baltic Sea and to or from a port located east of longitude 28˚10′ E.
According to the rules, passenger ships which carry more than 12 passengers will have to either discharge sewage into port reception facilities, or alternatively at sea – provided that nutrients have been reduced by 70% for nitrogen and 80% for phosphorus through on-board treatment.
Untreated wastewater has been identified as an important source of both hazardous substances and nutrients, the main cause of eutrophication leading to unwanted growth of blue-green algae that upset the Baltic Sea’s biodiversity.
If not their waters, then at least the experts of the world’s regional seas converged in Helsinki in late November to share best practices on the Sustainable Development Goal related to oceans and seas, SDG 14, and to start preparations on its joint outlook report to be presented at the Ocean Conference 2020.
The HELCOM-hosted workshop that took place in Helsinki from 25 to 27 November was a follow up of the UN Regional Seas Programme‘s Annual Meeting held in Berlin earlier in October and also co-hosted by HELCOM.
“Our organisations are truly the best place to translate the global visions into action at the regional level,” said the Executive Secretary of HELCOM, Rüdiger Strempel, during his opening remarks in Helsinki, referring to the driving role of the regional sea conventions and bodies on advancing the global environmental targets.
Two of the global frameworks, the SDGs and the Aichi targets, have long been important guidelines for HELCOM in working to conserve the global marine environment.
“The SDGs and Aichi targets are, in fact omnipresent in our everyday work,” said Strempel, adding that “both have proven to be key to advancing the ocean agenda, and decisively influence the policies we develop, the strategies we devise, the actions we implement.”
“At HELCOM and in the Baltic Sea, we believe that the various regional seas mechanisms can learn a lot from each other,” said Strempel, further stressing that despite HELCOM not directly being linked to the UN system, it continually takes account of the relevant UN goals and processes.
The other commitments were to establish a NOx Emission Control Area (NECA) in the Baltic Sea, to strengthen the implementation of the HELCOM Baltic Sea Action Plan to support ocean-related SDGs, and to identify Ecologically or Biologically Significant Marine Areas (EBSAs) in the Baltic Sea.
