What is it about?
Carbon dioxide (CO₂) is usually seen as a waste product that contributes to climate change. However, this paper shows how CO₂ can be used as a raw material to make fuels, chemicals, and plastics. By using CO₂ instead of fossil resources, chemical production could become more sustainable. The paper also compares different CO₂-based processes to find out which ones really help the environment when looking at the entire life cycle.

Why is it important?
This work is unique because it combines chemical research with life cycle assessment (LCA) to evaluate carbon dioxide (CO₂) conversion technologies from both a scientific and environmental perspective. Unlike many studies that focus only on how much CO₂ is used, this paper looks at the real environmental impact across the entire production process. It highlights where CO₂-based products can truly reduce the carbon footprint and where challenges remain. By linking catalysis and sustainability assessment, it provides a roadmap for future research and development toward a greener chemical industry.
Perspectives
Writing this review was a great opportunity to connect chemistry with real-world environmental challenges. I have always been fascinated by the idea that waste like carbon dioxide could be turned into something useful, and it was exciting to dig deep into both the chemistry and the life cycle impacts. I hope this article not only helps researchers develop better CO₂ conversion technologies but also encourages a broader conversation about how chemistry can drive true sustainability. More than anything, I hope readers find it inspiring to see science and environmental responsibility coming together.
