The city of Lahti, southern Finland, is home to a population of some 120,000 and has a goal to become carbon neutral in 2025, ten years before the country as a whole is due to meet the same target. Its environmental actions earned the city the title of European Green Capital 2021. Lahti city mayor Pekka Timonen believes that sustainability should always be part of normal city development and that being greener gives you a competitive edge.
