Introduction

This week we'll look at BECCS, biochar, and nature based solutions, which in the short to intermediate term are our best solutions for carbon dioxide reduction.

Learning Outcomes/Goals

Terrestrial capture and nature based solutions

1. BECCS - Bio-energy Carbon Capture and Storage
2. Biochar
3. Carbon farming
4. Trees
5. Plankton
6. Mineralization

Nature based solutions have at least five advantages over technical carbon capture, and specifically technical Direct Air Capture (DAC). The first is ability to roll out without material or energy inputs, or significantly reduced inputs. A term for this is "scale-in-place". The second if the the total carbon capture potential, measured in billions of tons of CO₂ per year, globally. This number applies to soil and forest (see Nature based solutions). The third is scale, the solutions cover much of the globe. The fourth is cost, requiring significantly lower development, and related to cost, is benefit to smaller populations and indigenous people. The fifth, and very important, is regeneration to the local environment.
