The greenhouse gas emission factors study in construction industry

By analyzing the problem of greenhouse gas emission in construction industry, found out the key factors of effecting the greenhouse gas emitting and set up the measurement index system of greenhouse gas emissions in construction industry. using the gray correlation analysis method, we can analysis the level of greenhouse gases released by all kinds of energy when the construction enterprises used in construction process and then draw the conclusion that construction of the size of the greenhouse gas emissions ranking in the construction business process. The largest is coal; the cleanest energy is the natural gas. Greenhouse gas emissions not only helps to control the energy saving effect of the construction process, but also guide our strategy of building low-carbon economy enterprises and enhance their core competitiveness.
