If they make full use of their powers, local authorities can make most applications of solar work today, without central Government support. That's the headline message from our new report, Leading Lights. This is a breakthrough for clean energy that will empower local leaders with ambitions to cut carbon and air pollution, and leaders who want to secure new and sustainable revenue streams for essential services. 

Analysis by C40 Cities shows to deliver on the Paris Agreement goals, every city across the UK should be powered by at least 90% renewable energy, making investment a necessity today. The good news is 85% of local authorities already own solar panels, nearly a third have integrated solar into their environmental strategies and the top 10 local authority investors have already collectively invested a cool £80m in solar.
