Quick takeaways
- Carbon removal and carbon capture serve distinct purposes in climate action, with the former focusing on extracting CO2 already present in the atmosphere.
- Despite its critical role in achieving net-zero emissions, carbon removal technology faces financial barriers hindering investment and development compared to cleaner energy alternatives.
Deep dives
Carbon Capture vs. Carbon Removal
Carbon capture and storage (CCS) and carbon removal are often misunderstood as the same concept, but they serve different purposes in addressing climate change. CCS aims to capture carbon dioxide emissions before they enter the atmosphere from sources like power plants, effectively preventing additional CO2 from contributing to global warming. In contrast, carbon removal focuses on actively extracting CO2 already present in the atmosphere to mitigate the effects of climate change. This distinction is crucial as various technologies develop across these fields, emphasizing the need for both to achieve net-zero emissions in the future.
