During this human-centric era, global warming has become a significant concern for humanity. The continuous increase in atmospheric carbon dioxide (CO2) levels is the primary driver behind global warming, which in turn triggers changes in weather system and earth climate. The swift in human-induced activities, such as urbanization and industrialization, have resulted in a rise in environmental CO2 levels. This CO2 is harnessed and employed as a carbon source in the synthesis of several value enhanced products using physical and chemical approaches. Nevertheless, these chemical and physical methods don’t provide a cost efficient and eco-friendly procedure. Certain cutting-edge and ecofriendly pioneering approaches such as those based on photobiosynthesis, bacterial electrochemical synthesis, bacterial gas fermentation processes and advancing bioenergy technologies like systemic biological approaches, hold the potential to cleanse the atmosphere by capturing CO2 and generate value-enhanced products from it. These methods have the ability to decrease greenhouse gas emissions, upsurge productivity and foster economic growth. By analysing the challenges and opportunities, this chapter illustrates the feasibility of upscaling these technologies for industrial implementation and their integration with existing energy systems. Ultimately, these bio-green technologies provide an essential pathway to combat climate change and pave the way for a more sustainable and greener future.
