"Rapid industrialisation and urbanisation in the past two decades have saddled cities like Linfen with heavy environmental burdens, damaging the health of local residents and fueling complaints .... However, Linfen is making efforts to turn its situation around ... The changes were made possible by changing the way the performance of local officials is evaluated, with promotions and other rewards linked to their efforts to improve the city's environment. Officials have not only closed down heavily polluting factories, but also taken action to add "green" features to the city." (Quoted from article)
