Advantages

Large mitigation potential

Annual GHG reduction can reach 1.0 Gt CO₂e, comparable to China's total terrestrial carbon sinks.

Cost-competitive

Abatement cost is lower than many other carbon removal technologies.

Region-specific pathways

Optimal regional utilization pathways are identified to guide deployment.

Applications

• Biomass power and heat：Generate power and heat from agricultural, forest, and manure residues, displacing fossil fuels.
• BECCS：Capture and store CO₂ during bioenergy conversion to achieve negative emissions.
• Agricultural residue valorization：Convert agricultural residues to energy, avoiding open burning pollution.
• Forest residue-to-energy：Use forest residues for clean energy, reducing fire risk.
• Regional carbon neutrality pathways：Develop region-specific carbon neutrality pathways based on resource endowments.
