By tapping into CO₂ emissions from industrial sources (such as power plants and chemical factories), CO₂-based polymers can contribute to a circular carbon economy. This model reduces the need for new fossil fuel extraction and minimizes the carbon footprint of plastic production. Furthermore, the use of renewable energy sources in CO₂ capture and polymerization processes can significantly reduce the overall environmental impact of polymer manufacturing, making the entire lifecycle of CO₂-based polymers more sustainable .
