The recent local elections in the UK have seen the Green Party gain 440 councillors and two elected mayors, emphasizing the potential for local authorities to address climate change. Despite having no formal climate duties, councils can leverage their powers over planning, transport, and social care to implement impactful initiatives. For example, councils in Cambridgeshire have collaborated on a plan to enhance home energy efficiency, while Leeds City Council has developed a city-wide district heating network. Public engagement is also rising, as seen in Kendal, where a citizens' jury highlighted the community's desire for more ambitious climate policies. However, local councils face significant challenges, including a 18% reduction in funding per person since the 2010s, which limits their ability to act. To maximize impact, new councillors should advocate for clear climate responsibilities and funding, ensuring that successful initiatives can become standard practice across the UK.
