It is learnt that, to fulfill energy saving and emission reduction, this circular economy pilot will be undertaken on four levels including districts and counties, industrial parks, enterprises and communities. The pilot work aims to explore effective modes of developing circular economy on different levels, breed a batch of circular economy models as reference and demonstration to units of the same kind, and promote the construction of an energy-saving and environment-friendly city. The pilot districts and counties and units are supposed to boast of such advantages as a good circular economy foundation, some achievements in the energy saving work, an impressive progress in industrial structure adjustment and enterprises culling, and an active promotion of pollution reduction and environmental treatment. With the goal of reducing resource consumption, decreasing waste emission and improving resource productivity, the pilot work expects an outstanding progress in energy saving and emission reduction during the 3-year pilot period.
