Abstract
Over the past several decades, a persistent and gradual elevation in atmospheric carbon dioxide (CO2) concentration has been observed. This rise in CO2 levels contributes to the greenhouse effect, resulting in the trapping of more heat at the planet's surface and subsequent global warming. Based on current trends, it is projected that the global temperature will rise by approximately 1.5 °C between the years 2030 and 2052. In light of this, it becomes imperative to mitigate global warming by undertaking substantial actions to reduce CO2 emissions. One approach to address this challenge is the sequestration of carbon dioxide, whereby it is captured from the atmosphere and utilized to produce valuable products. This has the potential to not only reduce the amount of CO2 in the atmosphere but also lower the cost associated with emissions reduction. Carbon dioxide, when present above ambient levels, can be directly employed in processes such as enhanced oil recovery, where it is injected into oil wells. Additionally, it can be chemically transformed into materials, chemicals, or fuels, such as methanol, cement, biochar, and fuel production. While no single technology can fully address climate change, several innovative approaches have been developed to assist in reducing atmospheric CO2 levels. These include direct air capture, cloud treatment, biomass-based construction, restoration of blue carbon habitats, and enhanced weathering. These methods and strategies for carbon dioxide sequestration are explored and described in order to counteract the adverse effects of CO2 and other greenhouse gases on climate change and global warming. It is crucial to recognize that numerous industries and companies play a substantial role in generating CO2 emissions. Nonetheless, it is feasible to mitigate the concentration of this gas through various measures, both pre and post-emission, thereby reducing its impact on the environment. Therefore, this study aimed to explore and describe innovative approaches and strategies for carbon dioxide sequestration in order to mitigate the adverse effects of CO2 and other greenhouse gases on climate change and global warming.
