Inevitable trend of low-carbon China's past economic model was more extensive.The development of economy took up a lot of raw materials and energy and the added value of products were not very high.This kind of development model has caused lots of pressure on resourses, energy,and environment,which is unsustainable.In this context,the low-carbon economy came into being.
Situation of China's Logistics Industry Small-scale logistics enterprises, low efficiency.Most of China's logistics enterprises are evolved from the traditional materials ,commercial storage and transportation companies.The scale of them are small.
Fig.1:Carbon emissions of various transport modes Warehousing is one of the central part of logistics,which plays an important role in buffer,adjustment and balance.Low-carbon warehousing requires the location of warehouses to be reasonable and the layout to be scientific so that to save transportation cost and improve the utilization rate of storage facilities.Warehouses adopt green building art and take full advantage of eco -friendly materials and green power in ventilation,lighting and other aspects[4].
Packaging should be on the basis of product’s life cycle.On the principle of reduce,reuse and recycle, reduce the use of disposable plastic packaging materials and promote the use of biodegradable and other environmental friendly packaging materials.The design of packages should be sizeable so that to save materials and costs.Moreover, promote the standardization of packaging so as to reuse the package.
