Yang X.F., Adair K.R., Gao X.J., Sun X.L. Hu J.Y., Ma J., Zhu Q.G., et al. Even though the CCUS approach has a pivotal role to play in our pursuit of carbon neutrality, the adoption of current CCUS technologies is hampered by their high energy consumption and costs. Owing to its controllable and tailorable electrical conductivity and inherent functional groups, biochar could be easily designed to have photonic, electronic, acoustic, and bio/redox interactions with other reactive substances, making it a viable alternative to replace unsustainable solid C-based catalysts.250, 251, 252, 253, 254 In addition, the possible use of biochar in the manufacturing of value-added construction materials has been explored.255,256 For instance, in a study, Das etal.257 obtained wood polypropylene composites with enhanced physical and mechanical properties after mixing wood and malleated anhydride polypropylene with biochar, suggesting that biochar with a high surface area may act as a reinforcing filler in the production of biocomposite materials. All authors discussed and approved the final manuscript. 2020. In many instances, being carbon neutral will limit contributions to climate change. Liu Y., Wang H., Jiang Z., et al.

Microbial production of recalcitrant dissolved organic matter: long-term carbon storage in the global ocean. Optimization of fertilizer and water use in croplands can greatly reduce GHG emissions in crop production systems.115 New synthetic N fertilizer types, such as slow- and control-release N fertilizers, and N fertilizers with urease and nitrification inhibitors, need to be developed to enhance N use efficiency.116 Better cropping systems, fertilization, and irrigation practices, and the use of advanced digital agriculture technologies, such as multi-sensor drone technology to allow farmers to manage crops, soil, fertilization, and irrigation more effectively and precisely, can reduce N fertilizer input and N2O emissions.117,118 For example, intermittent irrigation can substantially reduce the production of CH4 and increase CH4 oxidation, and thus can be an important choice to mitigate CH4 emissions from rice fields.119,120, Breeding crop varieties with a high N use efficiency (NUE) can reduce the N fertilizer application rate and reduce the emission of nitrogen oxides. McLeod E., Chmura G.L., Bouillon S., et al. Organic and inorganic model soil fractions instigate the formation of distinct microbial biofilms for enhanced biodegradation of benzo a pyrene. To achieve this, developing new methods for further optimization of waste recycling and nature-based processes in agroecosystems, along with the technological development of food factories, has the potential to reduce the need for chemical fertilizers and sustainably support human activities. Since the late 1970s, China has implemented six major ecological restoration projects, covering 44.8% of China's forests and 23.2% of its grasslands.175,176 The total annual C sink of the project area was 132 Tg C year1 in 20012010, over half of which was attributed to the implementation of these projects.176 Furthermore, for C sequestration in forest ecosystems, optimizing forest management strategies such as selection of suitable tree species, rotation length, and fertilization regimes are effective ways to increase the amount of forest C sequestration.177, 178, 179 Regulating stands into a more complex vertical structure will lead to faster growth and greater C sequestration in forests because multilayered canopies will occupy a range of light environments, resulting in high light acquisition and light-use efficiency.180,181 Since the SOC storage of broad-leaved forests is significantly higher than that of coniferous forests, afforestation should use mixed species planting and trees should be arranged according to the tree species' shade tolerance and successional characteristics.182 Fertilization, usually with N or P, could relieve plants from nutrient limitation and allow them to sequester more C in stems and soils.
