Rising global temperatures threaten human health, ecosystems, and economic stability, prompting international efforts under the Paris Agreement to limit warming to 1.5 to 2 degrees Celsius. To curb human-driven carbon dioxide releases, carbon capture, utilisation, and storage represents an urgent and feasible pathway. An evaluation of emission sources explores both human-made and natural inputs alongside existing technological developments designed to reduce atmospheric greenhouse gases. Furthermore, the review examines carbon dioxide storage and geological sequestration methods in detail, whilst also addressing opportunities for productive gas reuse. By merging direct capture methods with both commercial utilisation and long-term underground storage, these technological frameworks provide an appealing, potentially profitable mechanism to help industry and governments achieve international decarbonisation targets.
Climate change increasingly harms ecosystems, human health, and global economic stability as temperatures rise. Understanding how to directly capture, use, and securely store carbon dioxide provides policymakers and industrial sectors with practical, viable options to lower atmospheric greenhouse gas levels and meet international environmental agreements.
The text highlights carbon capture, utilisation, and storage as an appealing and profitable concept for meeting reduction targets, pointing towards application by industrial emitters. However, because the abstract describes a broad review of technological trends and storage options rather than a tested product, it remains early-stage guidance and provides no specific timeline or technology readiness level.

The Paris Agreement was aimed at reducing the global temperature to no more than 2ºC while continuing efforts to keep it to no more than 1.5 ºC to combat climate change and its detrimental effects. Scientists are more confident than ever that the damage already being caused by climate impacts will get worse as global warming progresses, with increasing adverse effects on human health, ecosystems, and economies. Therefore, to alleviate the anthropogenic emissions of carbon dioxide (CO2) into the atmosphere, carbon capture, utilisation and storage (CCUS) is considered the most urgent and viable approach. This work studied extensively the likely sources of CO2 emissions, via anthropogenic or non-anthropogenic; and the current trends in technology to mitigate CO2. Also, the work provides an extensive discussion on CO2 storage and sequestration and briefly discusses the possible utilisation of CO2. By combining the benefit of direct capturing of CO2 and utilization, with long-term CO2 storage, CCUS is thus an appealing and profitable idea for meeting CO2 reduction targets.
