Maritime Association for Clean Seas

What Maritime Association for Clean Seas does

The Maritime Association for Clean Seas (MACS) is a Singapore-headquartered industry alliance founded in November 2025 by ocean impact organization Seven Clean Seas. Its stated purpose is to convene ship owners and operators, ports, and other maritime stakeholders to reduce ocean plastic pollution and help the sector meet and exceed the IMO's 2030 plastic reduction goals. The alliance operates a tiered membership model — Founding Members, Association Members, Patron Partners, and Knowledge Partners — anchored by Berge Bulk, Bernhard Schulte Shipmanagement, X-Press Feeders, Britoil Offshore Services, and Pacific International Lines at launch, with DP World joining in April 2026, Howden as a patron, and IMPA and INTERTANKO as knowledge partners.

MACS does not sell a proprietary technology product. Its offering is a collaboration platform layered around Six Clean Seas' certified plastic recovery projects, comprising environmental impact measurement and reporting, onboard waste solutions, port interface support, seafarer engagement programs, and a Sustainable Procurement Working Group developing a maritime plastics taxonomy and procurement decision-support tools. Underlying technology is limited to the macs.earth web presence and a member login hosted on the sevencleanseas.aquip.io platform; there is no public API, mobile app, or documented integration surface.

The business model is membership-fee driven (recurring subscription). MACS monetizes organizational memberships rather than transactions, with tiered contribution levels appropriate to each member's role in the maritime value chain. The parent/operator relationship with Seven Clean Seas combines alliance dues with the operational credibility of SCS's certified recovery track record — 6,348,780 KG of plastic collected and ~20,000 lives improved across four projects in Indonesia and Thailand — and targets 100,000,000 KG recovered and 200,000 lives improved by 2030.

Core offering

MACS is an industry alliance platform that brings together ship owners, operators, ports, and maritime stakeholders to tackle ocean plastic pollution and operational waste at scale. It provides environmental impact measurement and reporting, onboard waste solutions, port interface support, seafarer engagement programs, sustainable procurement guidance, and access to certified plastic recovery projects. The alliance is structured around multiple tiered membership categories (Founding, Association, Patron, and Knowledge Partners) and aligns its work with the International Maritime Organization's plastic marine litter action plan and 2030 goals.

Product overview

MACS is a unified industry alliance platform built and operated by Seven Clean Seas, designed to help maritime stakeholders meet and exceed the IMO's 2030 plastic reduction goals. The platform comprises multiple interconnected services: environmental impact measurement aligned with certified plastic recovery projects, onboard waste solutions for vessels, port interface support to improve waste reception facilities, seafarer engagement and training programs, and a Sustainable Procurement Working Group developing standards and tools. These services work together as an integrated approach to ocean plastic recovery at scale and waste reduction across the maritime value chain, with initial focus on sustainable procurement, vessel waste measurement, and improved portside waste reception.

Regional players

• Clean Arctic Alliance: The Clean Arctic Alliance is a coalition of NGOs working to reduce shipping emissions and environmental impact in Arctic waters. It is comparable to MACS as a coalition mobilising maritime stakeholders to address shipping-driven environmental issues, although its geographic and topical focus (heavy fuel oil / Black Carbon) differs.

Direct peers

• Clean Shipping Coalition: The Clean Shipping Coalition is an international membership-based coalition of environmental NGOs advocating for cleaner shipping at IMO. It is comparable to MACS as a coalition influencing maritime environmental policy, with a more advocacy-driven rather than operator-led membership base.
• Global Maritime Forum: The Global Maritime Forum is an international not-for-profit that brings together shipping, port, finance, and policy leaders to drive sustainable ocean industry transformation. It is a direct peer to MACS given its global coalition model and focus on shipping decarbonisation and ocean stewardship.
• Sustainable Shipping Initiative (SSI): SSI is a multi-stakeholder initiative of shipowners, ports, and maritime stakeholders focused on sustainable shipping practices. It directly competes with MACS in offering a collaborative platform for the maritime value chain to address environmental and operational sustainability.
• Poseidon Principles Association: The Poseidon Principles Association is a global framework for measuring and reporting greenhouse gas emissions from ship finance. It is comparable as a sector-collective standard-setting body in maritime sustainability, although its focus is climate-aligned finance rather than plastic pollution.
• INTERTANKO: INTERTANKO is a knowledge partner of MACS and a global trade association representing independent tanker owners. It is directly comparable as a coalition-style membership body coordinating sustainability and regulatory action among tanker operators, intersecting with MACS's maritime stakeholder engagement.

Broad incumbents

• World Shipping Council: The World Shipping Council represents the global liner shipping industry on regulatory, environmental, and policy matters. It is comparable to MACS in convening container ship operators for collective action on sustainability issues like IMO compliance.
• International Chamber of Shipping (ICS): ICS is the principal international trade association for the merchant shipping industry, representing around 80% of the world merchant tonnage. Like MACS, it convenes global shipping operators and engages on regulatory and sustainability issues including IMO compliance.
• BIMCO: BIMCO is the world's largest international shipping association, representing shipowners, operators, and other maritime stakeholders. It is comparable to MACS as a broad industry association serving similar members and shaping standards, though its scope is far wider than plastic-pollution-specific.
• International Association of Ports and Harbors (IAPH): IAPH is the global trade association for port authorities and operators, representing over 180 ports across 80+ countries. It is comparable as it addresses port-side environmental sustainability and plastic reception facilities, intersecting directly with MACS's port interface support objectives.
