The first part of this project analyzes the demand, supply, and possible market price of domestic reduction credits generated from “Early Action Project” and “Offset Project”. The results show the possible market price of credit is expected could not give the sufficient incentives to the decision makers to apply the Offset Project further. In order to solve the problem, a flexible market adjust mechanism is suggested in this project. In the second part, the international decision making procedure of CDM on investment additionality is investigated. The localized industrial benchmarks are then established based on the empirical data. Furthermore, ten cases of investment analysis of Offset Project applications and five international CDM methodologies have examined by this project to facilitate the work of EPA. The statistical data of cross-countries’ energy usage and GHGs emissions management strategies are analyzed in this project to re-examine the policy of GHGs management. In turns, this project reviews the international best available techniques (BAT) and available technologies for GHGs reduction for the three industries, the iron and steel production, cement manufacturing, and large combustion plants system, respectively. The BAT reference documents of GHGs reductions for the industries above-mentioned are constructed as consequences. Also, the costs of voluntary GHGs reduction measures of the iron and steel production, cement manufacturing, and synthetic fiber manufacturing at domestic level are analyzed in the project so as to formulate effective environment-related policies. To assist with analysis and review the individual case of GHGs emissions evaluation and case tracking, this project has examined fourteen cases of environment development activities and three tracking cases have been checked with report for each individual case. Finally, four experts consulting meetings and a series of training programs are held so as to support the issues about the GHGs management.
