Maybe LCA( Life Cycle Assessment )，LCA is“The compilation and evaluation of inputs and outputs and their potential environmental impacts over the life cycle of a product system, including four interrelated, repeated steps: purpose and scope determination, inventory analysis, Impact Assessment, and interpretation of results.”. Life-cycle assessment is a technique and method for assessing the environmental impact of a product throughout its life cycle, from the acquisition of raw materials to the production of the product to its disposal after use.”

Dear Jiale Liu

Thank you for your answer.

My question was as follow:

Practically, how can I evaluate the greenness of an analytical method using any metric tool such as National Environmental Methods Index (NEMI), Analytical Eco-scale, Analytical Greenness Calculator (AGREE) and Green Analytical Procedure Index (GAPI).
