How Biochar Emerged as an Unexpected Champion

Mar 31, 2023

It is evident that biochar is no longer a niche topic. Though at first sight, it may resemble a familiar fossil fuel, this coal-like material has proved to hold enormous potential as a key technology piece in the battle against the climate crisis.

Interest in biochar carbon removal (BCR) got a boost in October 2018, when the IPCC classified it as a promising “negative emission technology”. Over the past years, BCR has been receiving increased attention, in part because it does not suffer from some of the drawbacks that affect other carbon dioxide removal (CDR) solutions, such as low technological maturity or uncertainty of cost-effectiveness.

This article examines why BCR seems to have been elevated recently and discusses the emergence of BCR as one of the main durable CDR methods available for delivery today. In addition, it will examine the body of research on its permanence, outline the available third-party standards and methodologies, and highlight some developers of high-quality BCR projects that CEEZER works with.

What is biochar, and what is it used for?

Biochar is made by heating biomass in an oxygen-limited environment through a process called pyrolysis. The biomass, which has removed CO2 from the atmosphere during plant growth, is broken down into a carbon-rich material that is then compressed into a solid form.
