Biobased products (biobased materials, bioenergy/biofuels, and biobased chemicals) are the futuristic replacement of fossil-based chemicals and considerably the best way of transiting towards a low-carbon economy (LCE) and which also can simultaneously mitigate the global challenges associated with the depletion of abiotic resources and climate change. Endurance with the biobased products is leading to the development of a biobased economy (BBE). Assessment of environmental sustainability achieved by the production of biobased products is important to understand their decarbonization potential, and all associated impacts with their life cycle and can be measured with life cycle assessment (LCA) tool. Life cycle sustainability assessment (LCSA) combines LCA with life cycle costing (LCC) and social life cycle assessment (sLCA). The framework of this paper is thus designed to provide an insight into biobased products with an overview of LCA as critical tools to measure sustainability. LCA methodology and its importance in determining sustainability for biobased products with associated limitations and probable solutions are also discussed. Circular economy (CE) integrating cradle-to-cradle (C2C) approach is also discussed as a promising endeavor to achieve LCE.
