📊 [Poll] Is biochar carbon removal (hashtag#BCR) an open or closed systems carbon dioxide removal (hashtag#CDR) method? 📊🔦

🔦 Like many of you, I followed the discussions around BCR on Monday during the carbon removal and carbon farming (hashtag#CRCF) expert group with great interest. The majority of it was spent on monitoring and liability, or better how to track the sequestered carbon over time.

🤔 What struck me more than anything, was the underlying assumption of BCR as an open-system carbon dioxide removal (hashtag#CDR) approach (like enhanced weathering), whereas my understanding is that it is a closed system approach (like direct air capture).

💚 Why does this matter? Because it completely changes how we think about regulating BCR.

👉 To me, folks are confusing the process of removing carbon from biomass through pyrolysis (= closed, fully measurable system) from the application of the biochar itself (= which can be in open systems such as soils or forests).

⁉ What is your take? Closed or open system? Why?
