The continuously rising emission of carbon dioxide (CO2) is a universal hazard which urgently requires collaborative action between policymakers and scientists. International treaties such as the Paris Agreement (with 196 signatories) reflect importance anthropogenic climate change truly global public concern. Towards aim recovery, most broadly utilized CO2 reduction strategies, including capture storage (CCS); capture, utilization, (CCUS); utilization (CCU) are reviewed herein. Of these methods, CCU shows greatest potential by recycling captured harnessing it resource to generate emissions-neutral or -negative value-added products (VAPs). Within methodologies, biologically-mediated (bio-CCU) microalgae promising biotechnology drastically reduce emissions. This review therefore details mechanisms photosynthesis sequester incorporate into valuable biomolecules. Microalgal cells utilize precursors macromolecules, lipids, proteins, carbohydrates, pigments; all discussed within frame industrial relevance market value. biofixation clearly demonstrated content myriad VAPs they produce. Moreover, pathways towards decreasing footprint (via prior atmosphere) increasing handprint (reducing emissions consuming CO2-neutral products) related bio-CCU presented Finally, existing challenges knowledge gaps acknowledged described, future research needs recommended.
