Leuven CO2 emissions drop 12% in 2024, largest fall since 2011

Leuven's CO2 emissions fell 12% in 2024 versus 2023, the steepest annual decline since city-wide measurements began in 2011, driven by significant reductions from households and traffic. Total emissions are now 31% below 2011 levels. The data is a single-city municipal report; underlying drivers (e.g., weather, energy mix, policy) are not specified, so the durability of the trend is uncertain.
