Algae related regulation & legislation

These pages have been edited and formulated in their present form under the EU-funded Horizon Europe project Locality. However, the activity leading to these pages predates the project and will hopefully continue after it ends.

Within the project we decided it was time to present all this regulatory information in a compact and accessible way, and to make it publicly available for the benefit of any member — or potential member — of the algal community. Many EU projects have or had a task dedicated to legislation and regulation, and most are asked to provide a legislative feedback or deliverable. We have collected much of the information from public or restricted-circulation deliverables of several projects. We have compiled data from the many sources cited throughout these pages, and we have discussed the topics in person and remotely with many knowledgeable people.

We invite all knowledgeable people in the community to contribute, modify and update the information on these pages, and to help make this a useful resource both for newcomers and for practitioners who have limited time and resources to collect this data themselves.

Access to these pages is open to anyone. Authoring, modification and commenting rights are restricted to known, authorised users. We are keen to provide anyone who is properly identified with a username that grants authoring, modification and commenting rights. We reserve the right to revoke those rights from anyone who does not comply with the purpose, style and ethics of these pages.

Comments, questions and suggestions by email are welcome from anyone at: legal@algen.eu

1. Within the present scope of these pages (EU-level regulation)

• 1.1 Missing chapters or missing relevant content in any of the existing chapters.
• 1.2 Corrections, clarifications, important additions or emphasis to the explanations already provided.
• 1.3 Missing regulatory topics not yet mentioned that are also relevant to algae under EU law.
• 1.4 Clearer or better explanations of any topic; graphic explanations are especially welcome.

2. National regulation

Contributions covering the specifics of regulation at the level of individual EU member states.

3. Non-EU legislation

Contributions on, and comparisons with, legislation relevant to the topics of this site in non-EU jurisdictions.

4. Upcoming and prospective developments

Information and discussion on upcoming rules, proposals, strategies, initiatives, theoretical frameworks and similar forward-looking material.

Note on national, non-EU and prospective content: we still have to define how such contributions are marked to be clearly distinguishable from the main subject of these pages (EU-level regulation in force). At least initially we expect such topics to be unevenly covered; they must be visually distinct from the core content.

The algal community in the EU is, in many ways, a large family: we meet regularly, we know each other or at least know of each other. Several organisations enable the social contacts and cooperation that make these pages possible.

• EABA — European Algae Biomass Association is the most important networking body, with more than 300 members from industry and academia, and organises many events. EABA has always been actively involved in regulation and legislation activities, representing the interests of the industry. Recently this activity has been amplified: Silvio Mangini, one of the most knowledgeable experts on algae, EU regulation and standardisation, has retired from his industrial duties and moved part-time to EABA.
• EU4Algae is a European Commission-led initiative (DG MARE) launched in 2022 to accelerate the development of a sustainable and innovative algae sector in Europe.

Most of the information, opinion and regulatory context discussed in these pages has been developed, reviewed or debated within the framework of EABA and EU4Algae activities and their associated events and working groups. We are grateful to both organisations and to their members and participants for the knowledge shared over the years.
