**6. Conclusions**

This chapter introduces an environmental impact assessment framework for denim fabrics. This framework provides an opportunity to calculate impacts of product developers' and/or designers' choices in defining the denim fabric they would like to develop using scientific LCA data. One can even compare the impact results of different types of denim fabrics without even producing the fabric itself. Calculating and sharing this detailed science-based data also represents a new level of transparency. On the contrary to the common belief of raw materials being the main impact generators in denim fabrics, the framework also proves that impacts occurred during denim fabric manufacturing, during the production of the raw and auxiliary materials, and impacts of the background processes should all be taken into consideration.

There are challenges in LCA calculations since the primary data is highly company-specific. Therefore, the chapter focused on normalizing the data and creating a scaling that can be used in decision-making.

Greenwashing is not only denims but today's one of the growing problems in every sector, in every product. Baseless claims and marketing statement caused this problem and now it is really hard to clean it up. Certifications and labels were seen as one of the solutions to this problem however, industry experiences misapplications during *Life-Cycle Assessment as a Next Level of Transparency in Denim Manufacturing DOI: http://dx.doi.org/10.5772/intechopen.110763*

the certification process in the last couple of years. There is an information pollution in the market on what is sustainable denim. This framework will help designers/ companies compare their choices about their sustainable denim fabric definitions via science-based data.
