Nongovernmental valorization of carbon dioxide

Area of Science:

• Environmental Science
• Chemistry
• Biogeochemistry

Background:

• Carbon dioxide (CO2) is the primary greenhouse gas, driving climate change.
• Current carbon management focuses on emission reduction and sequestration in sinks.
• Limited consideration has been given to utilizing CO2 on a scale impactful to atmospheric concentrations.

Purpose of the Study:

• To survey the potential and limitations of using carbon dioxide as a chemical feedstock.
• To evaluate the role of natural biomes (trees, vegetation, soils) in carbon management.
• To assess the feasibility of large-scale carbon withdrawal for atmospheric amelioration.

Main Methods:

• Literature review and analysis of existing research on carbon utilization and biome-based storage.
• Assessment of CO2 as a feedstock for organic chemicals, fuels, and inorganic materials.
• Evaluation of natural carbon sinks for their capacity and limitations in carbon management.

Main Results:

• Carbon dioxide can be a valuable feedstock for various chemical products and fuels.
• Natural biomes offer significant potential for carbon sequestration, but face limitations.
• Large-scale carbon withdrawal is necessary to meaningfully impact atmospheric CO2 levels.

Conclusions:

• Utilizing CO2 as a feedstock and enhancing biome carbon storage are complementary strategies for climate change mitigation.
• Further research and technological development are needed to realize the full potential of these approaches.
• Integrated strategies combining industrial utilization and natural solutions are crucial for managing atmospheric carbon dioxide.
