Let's put our skills to work.
The community is actively working on these issues:
Cities worldwide are committing to carbon neutrality, but the gap between political targets and physical reality is vast. Decarbonizing urban heating, transport, construction, and waste systems within a generation requires coordinated action across sectors that have never worked together at this speed.
Forests across Europe and beyond are experiencing accelerating decline driven by climate change. Drought, rising temperatures, insect epidemics, and fungal diseases are killing trees at unprecedented rates across multiple species, turning forests from carbon sinks into carbon emitters.
Climate change is accelerating. We need actionable, community-level ideas to reduce greenhouse gas emissions where we live and work.
Hydroponics can revolutionize urban farming, but current systems are too expensive and complex for most people. We need affordable, beginner-friendly solutions.
Housing prices are skyrocketing, making it difficult for many to find affordable places to live. We need creative solutions to this crisis.
Access to clean water is a basic human right. We need to find ways to make it more affordable and accessible for every community.
Our public transport system is outdated and inefficient. We need ideas to enhance its reliability and accessibility for all residents.
Every year, millions of tons of waste end up in landfills. We need innovative solutions to reduce household waste and promote recycling.
