RezerolabDades: check your Catalan municipality's zero waste progress
30+ indicators for 300 municipalities, updated every year RezerolabDades is a free public data tool built by Rezero that analyses over 30 waste-related indicators for approximately 300 Catalan municipalities each year. Indicators include separate collection rates, residual waste per capita, composting volumes, and proximity to Zero Waste targets. The tool is used by municipalities, researchers, journalists, and residents to track whether their area is moving toward or away from zero waste. What you can do with it - Look up your municipality's separate collection rate and compare it to Catalan neighbours - Share results with your local council as evidence for improving collection infrastructure - Use the data to write letters, reports, or media pieces about waste performance in your area - Identify which municipalities are models worth visiting or learning from How to access it - Visit Rezero's data page for the latest RezerolabDades release - Rezero publishes an annual summary report alongside the raw indicators Why it matters Accountability needs data. RezerolabDades makes it impossible for municipalities to hide poor performance behind vague statements: and equally easy to celebrate genuine progress. It is one of the most sophisticated municipal waste monitoring tools in Europe at a regional scale. Source & repost Shared here so you can get inspired or find action already happening near you.

Plant seagrass meadows with Posidonia volunteers
Help Mediterranean seagrass meadows recover Posidonia oceanica meadows shelter fish nurseries, calm waves, and store carbon along Spanish and Italian coasts. Volunteer planting and monitoring programmes invite residents to restore underwater meadows bay by bay. What you can do - Join GreenLife4Seas citizen science and restoration calls along the Catalan and Apulian coasts - Learn safe planting techniques with local diving clubs and marine biologists - Map meadow edges and report anchor damage to harbour managers How it works Teams coordinate seasonal planting windows when water is clear. Volunteers with snorkel or dive certification plant shoots in marked plots and return to photograph recovery. Why it matters Seagrass meadows are living breakwaters: they protect beaches, feed fisheries, and keep water clear for everyone who swims nearby.

Volunteer for Mediterranean marine reserve management
Steward MPAs from Barcelona to Sicily MedPAN links volunteers with Mediterranean protected areas: patrol support, visitor education, and habitat monitoring on islands like Ustica and in Catalan coves. What you can do - Browse MedPAN member reserves near you and ask about volunteer roles - Lead snorkel briefings that teach respectful wildlife watching - Help translate visitor guides so local fishers and tourists share the same rules How it works Reserves train stewards on seasonal tasks: nesting season rope lines, invasive species pulls, and underwater photo transects. Why it matters Protected coves recover fast when residents feel ownership: compliance rises and fish spill over into neighbouring waters.

Barcelona Zero Waste Observatory: residents and experts shaping city policy
A city advisory body where zero waste is built in public The Barcelona Zero Waste Observatory is an advisory body created by Barcelona City Council to bring together Zero Waste experts, civil society organisations, and community representatives who drive the zero waste movement in the city. Rezero: the Catalan Zero Waste organisation is one of the founding participants. The Observatory coordinates communication between the City Council and the entities running projects on the ground, giving residents and advocates a direct channel into municipal decision-making. What the Observatory does - Brings together 20+ organisations working on waste reduction, reuse, and circular economy in Barcelona - Serves as the official advisory body to the city on Zero Waste policy and plans - Facilitates joint projects: from school food surplus management to plastic-free market studies - Publishes findings and recommendations publicly How to get involved - Follow Rezero for Observatory updates and public consultation opportunities - Attend open events where Observatory members present findings to Barcelona residents - If you run a Zero Waste initiative in Barcelona, contact Rezero about joining the Observatory network Why it matters Cities that embed civil society into policy structures tend to make stronger and longer-lasting zero waste commitments. The Barcelona Observatory is a governance model other European cities are watching closely. Source & repost Shared here so you can get inspired or find action already happening near you.

Less food waste: more community benefit from school kitchens Rezero, working with the Barcelona City Council and the La Noguera City Council, developed a programme that channels surplus food from school canteens to community benefit rather than the bin. The collaboration maps the flow of leftovers, works with catering providers to reduce production overruns, and connects remaining surpluses with food banks and social organisations. When & where - Ongoing during school terms at participating Barcelona city schools and La Noguera comarca schools - Programme runs through catering contracts coordinated by Barcelona City Council, La Noguera City Council, and Rezero How to engage - If you work in a Barcelona or Catalan school, ask your catering provider and school board about joining Rezero's food surplus programme - Follow Rezero for the programme's expansion to additional municipalities - Parents can raise the food surplus topic at school board meetings as a concrete sustainability action Source & repost Shared here so you can get inspired or find action already happening near you.
