Energy & Environment
The natural world and the infrastructure that sustains it.
European cities sit between the EU Green Deal's ambition and the daily reality of delivering it. The Mission for 100 Climate-Neutral and Smart Cities by 2030, the Covenant of Mayors for Climate & Energy, and the Renovation Wave all converge at municipal scale — where energy systems, building stocks, water networks, and green infrastructure must be replanned together.
This cluster brings together resources across three intersecting domains: clean energy generation and distribution; circular use of water, waste and material flows; and climate adaptation through nature-based solutions and resilience planning. EU funding instruments (Horizon Europe, LIFE, Cohesion, the Just Transition Fund) flow through programmes coordinated by NetZeroCities, ICLEI Europe and the Covenant of Mayors.
Drill into each leaf for grid and renewable-energy resources, circular-economy and resource-management tools, or climate-resilience and nature-based-solutions case studies — for sustainability officers, energy planners, climate-adaptation teams and the civil society organisations supporting them.
