<![CDATA[Industrial decarbonization requires carbon-management technologies that can reduce residual emissions without creating excessive energy, resource, or land burdens. This study aimed to map and compare the efficacy of bio-based carbon capture technologies for mitigating greenhouse gas emissions and supporting industrial sustainability. A systematic review, evidence mapping, and quantitative synthesis were conducted on 84 studies published between 2010 and 2026, covering microalgae, microbial fixation, carbonic-anhydrase-assisted capture, biomass-derived sorbents, biochar, and bioenergy with carbon capture and storage. Data were evaluated across technical performance, environmental effectiveness, economic feasibility, industrial scalability, and storage permanence. The findings showed that carbonic-anhydrase-assisted systems and bioenergy with carbon capture and storage achieved the strongest gross capture performance, while biochar and bioenergy with carbon capture and storage provided greater long-term storage potential. Microalgae and microbial systems offered valuable co-benefits through wastewater treatment, nutrient recovery, and biomass production, although energy-intensive cultivation and downstream processing reduced their net climate benefits. The study concludes that capture efficiency alone is insufficient for evaluating technological efficacy. Credible industrial deployment requires life-cycle greenhouse gas assessment, durable carbon storage, sustainable feedstock sourcing, realistic scale-up evidence, and integration with broader decarbonization strategies across diverse industrial sectors and operating conditions under transparent monitoring, reporting, and verification frameworks worldwide.]]>
