ABSTRACT
This chapter describes most advanced and robust effort to certify alternative fuels as sustainable. Having tried to examine all the things that present themselves as sustainability assessment resources. The whole field of sustainability assessment and certification is very dynamic, and the Roundtable on Sustainable Biomaterials (RSB) is evolving at the pace necessary to adjust to the situation. This starts to become particularly apparent relates to labor and human rights not only does it support the rights of workers as enshrined in the International Labour Organization's Conventions, Protocols, and Recommendations but in some ways surpasses them. So an organization for sustainability assessment and certification does not need to impose any specific carbon reduction value worldwide. The chapter also describes how systems of life-cycle analysis need to probe into materials and process pathways to understand if the inputs the materials, energy, and processes that provide what is needed to make sustainable fuel, themselves, sustainable.
