The challenge to scale carbon removal to 10 gigatonnes by 2050 is clear. Despite scientific recognition of its need, this sector is still in its early stages of development with just 0.006% of this target met so far.
Understanding how scalable a carbon removal method is, and which factors will have an impact on scalability, is crucial to understanding this new market and to inform where investment needs to be directed in this nascent industry.
This assessment seeks to, for the first time, unpick how scalable five different carbon removal methods are on a comparative basis.
1. The carbon removal¹ market needs transparent metrics and frameworks to assess its potential to scale.
2. BeZero Carbon has built a methodology which follows three steps: defining the System Boundaries, identifying the Universal Factors and assessing carbon removal methods using a qualitative rubric.
3. The results of the assessment of Bio-energy with Carbon Capture and Storage (BECCS), Biochar, Direct Air Capture (DAC), Enhanced Weathering and Ocean Alkalinity Enhancements will be published in January 2023.
¹For the purpose of this report, “carbon removal” refers to only engineered solutions.
