Abstract

After the Industrial Revolution, the ever-increasing atmospheric CO₂ concentration has resulted in significant problems for human beings. Nearly all countries in the world are actively taking measures to fight for carbon neutrality. In recent years, negative carbon emission technologies have attracted much attention due to their ability to reduce or recycle excess CO₂ in the atmosphere. This review summarizes the state-of-the-art negative carbon emission technologies, from the artificial enhancement of natural carbon sink technology to the physical, chemical, or biological methods for carbon capture, as well as CO₂ utilization and conversion. Finally, we expound on the challenges and outlook for improving negative carbon emission technology to accelerate the pace of achieving carbon neutrality.

Keywords: Carbon footprint reduction; Carbon neutrality; Carbon utilization; Climate change mitigation; Negative carbon emission; Renewable energy.
