Abstract
For taking measures to reduce greenhouse gas emission in small-to-medium-sized enterprises, it is discussed about how to evaluate their performance in management of the enterprises in this paper. In addition to a new assessment with a “spiral checking and feedback system”, a new management based on this assessment is proposed for reasonable evaluation of the taking measures and the CO2 reduction. A quantitative case study is conducted according to procedure and estimation of the above method for a company manufacturing construction materials. This study reveals that the saving of energy cost, which is attained by the suitable taking measures, brings about a effective profit to the manufacturer.
