In “Kyoto protocol”, greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and three replacements for chlorofluorocarbons (HFCs, PFCs, SF6). Greenhouse gases are important to keep track of because they trap heat in the atmosphere, which over many years causes changes in climate worldwide. A GHG emission inventory serves to track continuing progress in efficient resource utilization. In addition, these metrics serve as the benchmark for evaluating the effectiveness of all future GHG reduction initiatives such as new construction practices, energy conservation projects, and the use of carbon offsets. Furthermore, the GHG Reports which can be evaluated by an independent verification body can increase the market transparency and credibility of the organization. This study proposes a two-stage research structure. In the first stage, the standards of ISO/CNS 14064-1 and the GHG protocol are used to investigate the required procedures and methods of GHG inventory for a distribution center (DC). Based on these standards, the GHG report for the DC is gained. In the second stage, based on the major GHG emitters of the DC, the feasible GHG reduction strategies are drawn up. Then, the analytic hierarchy process (AHP) is used to evaluate the critical strategies of GHG reduction for the DC. Finally, a real DC is used to demonstrate the research structure and the year of GHG inventory is 2010. Based on the results of the first stage in case study, the total GHG emission for the case DC is 133.64 tons CO2e/year in 2010. Comparing the emissions of major GHG emitters, the emissions of “automotive diesel oil” and “purchased electricity” are 79.58 tons CO2e/year and tons 44.10 CO2e/year, respectively, and the sum is near 93%. Moreover, the results of the second stage in case study show that the importance of “automotive diesel oil” ranks first in the second layer of the AHP structure, the importance of “fuel usage” ranks first in the third layer of the AHP structure, and the importance of “planning the optimized delivery routing and implementing satellite navigation system” ranks first in the fourth layer (i.e., reduction strategies) of the AHP structure.
