When we relaunched Tackle the Crisis at the start of 2025, our goal was simple: to shift the climate conversation from despair to determination. As set out in our ESG report, we committed to sharing positive, solutions-focused stories every month that highlight how people, businesses and communities are working together to protect nature and build a more sustainable future.
From biodiversity restoration to circular innovation, this campaign has allowed us to celebrate the ideas and partnerships driving real change. As 2025 comes to a close, we’re proud to say we’ve met that goal – twelve months of good news that remind us what’s possible when we tackle the crisis with hope, collaboration and purpose.
Below are our highlights from September to December. You can catch up on our other posts here and here.
September
Community Energy for Social Housing in Otterbeek
We highlighted Community Energy for Social Housing in Mechelen, Belgium – the winner of the 2025 European Sustainable Energy Award for Local Energy Action. The project has transformed 200 social housing units with solar panels, shared electric vehicles and green spaces, providing affordable energy while building community resilience. Funded through citizen investment and delivered by the City of Mechelen, the Klimaan energy cooperative and Woonland housing association, it’s a blueprint for socially inclusive climate action.

Traceless Materials: Plastic-free innovation from Hamburg
Based in Hamburg, traceless Materials is revolutionising the fight against plastic pollution. Their pioneering biomaterial, made from agricultural residues rather than fossil fuels, is home-compostable and breaks down naturally in just a few weeks, leaving no microplastics behind. Even better, it can be processed on existing industrial machinery, helping manufacturers transition to sustainable materials without overhauling production. This is exactly the kind of scalable circular solution that embodies the spirit of Tackle the Crisis. Learn more
rrreefs: Restoring coral reefs with science and art
The Zurich-based social enterprise rrreefs is combining marine science, design and community engagement to revive one of the planet’s most vulnerable ecosystems. Using 3D-printed clay modules, they create reef structures that provide shelter for fish and allow coral to settle and grow—bringing biodiversity back to degraded reef sites within months. With projects across the tropics and a goal to restore 1% of coastal coral reefs by 2034, rrreefs shows how innovation and ecology can thrive together. Find out more
November
Pine martens return to Exmoor
In one of the UK’s most exciting rewilding stories this year, Devon Wildlife Trust released the first pine martens into Exmoor National Park, marking their return to south-west England after more than a century. The project, supported by landowners and local communities, is helping to restore balance to woodland ecosystems and reintroduce a key native predator that plays a vital role in maintaining biodiversity.

Mycobuild: Can mushrooms build a circular future?
Could fungi really help save the world? Researchers think so. The team at Norwegian Mycelium (NoMy) and the Institute for Circular Economy of Bio:Polymers (ibp) at Hof University of Applied Sciences are exploring how fungal mycelium – the root-like network of mushrooms – can be turned into compostable, carbon-storing insulation materials. Mycelium-based products require less energy to produce, replace fossil-derived materials like Styrofoam, and even lock away CO₂ during growth. The Mycobuild project aims to scale production by 2026, showing how nature’s own recycling system can help us build a more circular, sustainable future. Read more · Watch the TED Talk
Wavy Wonders: Turning seaweed into sustainable snacks
In Copenhagen, Wavy Wonders is proving that sustainability can be both delicious and practical. Their innovative seaweed snacks use fast-growing winged kelp—a carbon-sequestering, fertiliser-free marine crop that supports healthy ocean ecosystems. By replacing resource-intensive ingredients with regenerative alternatives, Wavy Wonders is showing how food innovation can be a nature-based solution in itself. Learn more

Berlin’s citizen-led tree law takes root
In a landmark example of community-driven climate action, the city of Berlin adopted a draft law proposed by the citizen initiative BaumEntscheid Berlin, committing to plant hundreds of thousands of new trees by 2040. The plan aims to bring the total number of trees in the German capital to over one million, helping to cool urban areas, improve air quality and increase biodiversity. What makes this story remarkable is its people-powered foundation gathered more than 33,000 signatures to make this happen, proving that grassroots democracy can shape real environmental policy.

Looking Ahead
Across 2025, Tackle the Crisis has shared stories of innovation, restoration and hope—from renewable energy and rewilding to social innovation and circular design. Together, these examples reflect the core values of EnviroSustain: that sustainability thrives where people and planet work in partnership.
As we move into 2026, our commitment continues. We’ll keep spotlighting positive change and amplifying the individuals and organisations proving that progress is possible, one story at a time.
