Although these opinions may be conflicting, it can be accepted by most experts. Then, VIKOR method is introduced to combine these opinions to generate the final result which is considered as the best solution for reducing carbon emission in chemical industry. Evidently, this solution will help chemical industry decrease or control carbon emissions.
