Poland's northern coast borders the brackish Baltic Sea, a saltwater sea featuring estuaries and lagoons that suffer from chronic eutrophication due to agricultural runoff, urban waste, and industrial discharges. The Baltic Sea is one of the most eutrophied seas globally, with nutrient loads leading to dead zones and algal blooms. 

Verity One Ltd. proposes the deployment of oyster-based biofiltration systems to naturally remove nitrogen and phosphorus from these waters, enabling the creation of verified blockchain-backed Nutrient Credits. These credits align with EU environmental directives, such as the Water Framework Directive and Marine Strategy Framework Directive, and support regenerative marine economies through the HELCOM Baltic Sea Action Plan.

  • Vistula Lagoon & Delta: High nutrient loads from the Vistula River; HELCOM hotspot with heavy eutrophication.
  • Oder River & Szczecin Lagoon: Receives ~56,750 t N and 2,800 t P annually; shared with Germany, persistent poor water quality due to internal loading.
  • Gulf of Gdańsk & Puck Bay: High eutrophication (HELCOM HEAT assessment); seasonal hypoxia and cyanobacteria blooms.
  • Curonian Lagoon & Vistula Spit: Intense coastal eutrophication during warm months.

 

HELCOM, formally known as the Baltic Marine Environment Protection Commission (also referred to as the Helsinki Commission), is an intergovernmental organization dedicated to safeguarding the marine environment of the Baltic Sea. It serves as the governing body for the Convention on the Protection of the Marine Environment of the Baltic Sea Area (commonly called the Helsinki Convention), which aims to prevent and eliminate pollution in the Baltic Sea from all sources, including land-based activities, shipping, and atmospheric deposition.

Established in 1974 with the signing of the original Helsinki Convention in Helsinki, Finland, HELCOM was one of the first regional seas conventions globally. The convention was updated in 1992 to address emerging environmental challenges and entered into force in 2000. HELCOM has evolved into a key platform for coordinating environmental policy, science, and action in the Baltic region, influencing broader EU and international marine protection efforts.

Its primary goals include reducing pollution from nutrients (e.g., nitrogen and phosphorus leading to eutrophication), hazardous substances, and marine litter; promoting sustainable maritime activities, such as shipping and fisheries; conserving biodiversity and habitats, including through marine protected areas; monitoring and assessing the environmental status of the Baltic Sea via regular reports and indicators; and implementing the Baltic Sea Action Plan (BSAP), a comprehensive strategy updated in 2021 to achieve a healthy Baltic Sea by 2030, with ongoing revisions as needed.

HELCOM also facilitates cooperation on issues like hydrographic surveying for safe navigation and response to environmental emergencies. As of 2025, recent activities include adopting a list of priority substances and substances of concern to address emerging risks, hosting a stakeholder conference on hazardous substances in March 2025, and granting observer status to the International Union for Conservation of Nature (IUCN) in April 2025 to enhance marine conservation collaboration.

HELCOM's membership includes all coastal states bordering the Baltic Sea, plus the European Union, ensuring coordinated regional action. The organization is headquartered in Helsinki, Finland, and operates through annual meetings, working groups, and expert networks.

The Baltic Sea is one of the world's most polluted enclosed seas, facing challenges like eutrophication, biodiversity loss, and climate change impacts. HELCOM plays a crucial role in addressing these through binding recommendations, data-driven assessments, and alignment with EU directives like the Marine Strategy Framework Directive. Its work supports global goals under the UN Convention on the Law of the Sea and the Sustainable Development Goals (especially SDG 14: Life Below Water). Despite progress in areas like phosphorus reduction, the overall contamination status remains elevated across the Baltic Sea as of the latest 2025 assessments.

Proposed pilot sites leverage oyster deployments for nutrient filtration, with estimated reductions based on regional data and similar projects.

SiteAnnual Nutrient Load (t N/P)Pilot Size (Oysters Deployed)Projected Reduction (kg N/P per Year)
Vistula LagoonHigh (part of 349,000 t TN / 13,800 t TP from major rivers)100k–500kUp to 5,000 kg N / 250 kg P
Szczecin Lagoon56,750 t N / 2,800 t P100k–500kUp to 4,000 kg N / 200 kg P
Gulf of GdańskVariable, high eutrophication index50k–200kUp to 2,500 kg N / 125 kg P

Poland's major ports—Gdańsk, Gdynia, Szczecin, and Świnoujście—handle significant traffic, contributing to nutrient pollution via bilge discharge, greywater, and runoff. Oyster reefs can act as buffer zones near shipping lanes, filtering pollutants and enabling ESG-compliant offsets.

  • Enhance ESG profiles for maritime operators.
  • Support Blue Economy by tying credits to shipping-based nutrient offsets.
  • Address port-related emissions and comply with EU regulations.

  1. Deploy: Install oyster reefs in targeted hotspots using IoT-monitored systems.
  2. Monitor: Real-time data collection via AI (IBM Watson) and blockchain for verifiable filtration metrics.
  3. Certify: Quantify nutrient reductions through biomass analysis and third-party verification.
  4. Tokenize: Issue blockchain-backed Nutrient Credits linked to Pearl Tokens for governance and incentives.
  5. Report: Provide dashboards for stakeholders, aligning with HELCOM and EU reporting.

Verity One Ltd. invites collaboration with Poland’s Ministry of Maritime Economy & Inland Navigation, HELCOM, and port authorities to launch pilots in the Vistula or Szczecin Lagoons. Contact us to discuss technical setup, funding, and integration plans.
