The steel industry in China has developed over the last seventy years to become the world’s largest, now accounting for the 50% of the world’s production. The steel plant in Qingdao is housed in immense warehouses; white light pours in from clerestory windows onto the luminescent red hot steel as it is moved through several processes to create rods, bars, tubes and other products. The steel plants of China rely directly on energy inputs from coal-fired power stations; the burning of coal has led to extreme levels of air pollution and recently it has been announced that Beijing will close all its coal plants. The closures are part of a broader trend in China, which is the world’s biggest carbon emitter. Facing pressure at home and abroad, policy-makers are racing to address the environmental damage seen as a by-product of breakneck economic growth.
