I don't have the sources or exact numbers on hand, but I remember reading that the world's extractive & production processes create something like ~4 billion tons of oil, ~4 billion tons of iron, ~x billion tons of cement, and ~50 billion tons of sand, per year. These industries developed over many years and as you note are distributed globally. With market demand and regulatory pressure, we believe achieving CO2 removal across different modalities at the giga-ton scale is possible in our lifetimes.

That being said, we try to bring a conservative approach to our scaleup plan. The most immediate challenge is demonstrating CO2 removal at the megaton scale (1 million tons per year) to validate the process and meet short-term demand for voluntary offsets.
