Abstract

With the development of industry, carbon emissions are increasing: global temperatures are rising, habitats are shrinking, sea level rises and other issues are emerging one after another, climate change is getting more and more attention, and strategic goals such as carbon neutrality have also been formulated to alleviate global climate change. As a material to mitigate climate change and help achieve the goal of carbon neutrality, biochar can effectively absorb and store carbon and reduce carbon footprints. Through a critical analysis of the role of biochar in achieving carbon neutrality, this paper analyzes the principles of carbon absorption using biochar in agriculture, etc., and points out the existing limitations of biochar, such as high cost and land occupation, and efficacy instability, and gives the existing research based on the limitations. An increasing corpus of research has pinpointed elements like the temperature at which biochar is formed and the kind of biochar that is best for a certain soils and plants. Some solutions and mitigation methods conclude that biochar has a high development potential to help achieve carbon neutrality.
