In order to achieve energy conservation goals made in 2009
Climate Summit in Copenhagen, measures to realize low-carbon production in manufacture
enterprises in China were studied. The establishment and application of low-carbon
production evaluation system were introduced. The two main methods: Energy flow
analysis and AHP (Analytic Hierarchy Process) were brought in to satisfy the
target. The path of carbon travelling through the whole process was discussed.
Also, a weighted indicator system based on the analysis of energy flow was constructed.
A three layer framework considering five different aspects which pointed out
a direction to achieve the energy-consumption goal was designed. The results
showed that the system was available and the energy recycling was the most critical
factor for the low-carbon production and also the most effective way for energy
management to achieve its environment-friendly goal. Moreover, a practical example
was given and the effectiveness of the evaluation system was verified.
