Ted Christie-Miller from BeZero on assessing the scalability of carbon removal

An approach to assessing long-duration carbon removal methods in a world with few deployed carbon removal projects

Episode 19 of The Carbon Curve is with Ted Christie-Miller, Head of Carbon Removal at BeZero Carbon

Scalability is essential to the success of long-term CDR deployment - it is broadly acknowledged that by midcentury, CDR must grow from its current capacity of thousands of tons to billions of tons of removal per year. But how do we evaluate the potential to scale, the barriers that could prevent the necessary scaling, and the levers needed to overcome these barriers?

BeZero Carbon is a ratings agency for the voluntary carbon market. Combining expertise across climate science, finance and policy, it provides ratings, risk and data tools that improve information accessibility and decision making with the aim to build markets for environmental impact. As part of its work on carbon removal, BeZero Carbon has developed a methodology for assessing scalability across multiple carbon removal methods. 

Ted Christie-Miller, BeZero Carbon’s Head of Carbon Removal, discusses how the methodology was developed, what it can be used for, what its limitations are, and what’s next for BeZero on assessing CDR going forward.

In this episode, Na’im and Ted discuss:

  • The strategic importance of long-duration CDR to BeZero Carbon and why BeZero decided to assess the scalability of long-duration CDR methods;

  • The methodology used to assess CDR methods and how it’s different from methodologies used by other groups;

  • Challenges and surprises the team encountered when assessing scalability;

  • Key take-aways from this analysis and how BeZero hopes this assessment will be used, as well as planned future work.

The Carbon Curve
Few people realize this, but fending off the worst effects of climate change is going to require the removal of billions of tons of CO2 from the air every year. To even comprehend that scale - imagine running today's oil and gas sector... in reverse. Every two weeks, carbon removal specialist Na'im Merchant speaks to entrepreneurs, innovators, activists, and policy experts advancing bold ideas to scale up carbon dioxide removal to bend the curve on climate change.
