Environmental considerations have led organizations to take an important role in designing
environmentally-friendly, recyclable products to complement improvements in the environmental
standards of services. In this context, the application of lean practices may result in pollution reduction.
In this paper, firstly, the integration of green lean approach is discussed, and then the limitations of green
lean approach are identified. Finally, we integrate the Six Sigma approach in order to overcome these
limitations, and assess the performance of the green lean approach. Measurement System Analysis and
Gage Control are used as methodology to measure the variations of the process in order to decrease
unfavorable ecological impacts of companies' products or services, while enhancing environmental
efficiency.
