Katowice, a major Polish city historically tied to coal, has joined the Powering Past Coal Alliance to phase out coal power and promote green energy. The city aims to be a model for others, having committed to significant CO2 reductions and investments in green infrastructure. Despite initial challenges like high unemployment due to mine closures, Katowice has diversified its economy and is now focusing on services and technology.
