Nowadays the deteriorating global climate alters us to lower the energy consumption and reduce the emission simultaneously. In the aspect of economy, energy-saving and emission-reduction are feasible methods to lower the product cost, and to obtain more profits for a factory or an enterprise. There are increasing energy-saving and emission-reduction technologies designed by governments, device manufacturers, software companies, research institutes. Thereby a real problem arising is how to select the appropriate solutions for a factory or an enterprise according to their real production characteristics and different duration plan for their future development. Cloud service, as a novel service mode, supplies a new solution for the problem of selection and realization about the possible technologies to save energy consumption and reduce the emission from the real production line. Therefore this paper proposes a technical solution of service cloud building for energy-emission and emission-reduction in manufacturing industry. Then main function modules are designed, and this paper explains the key-technologies to build this service cloud respectively. Finally some useful conclusions are drawn for the real application of service cloud in the engineering respectively.
