The UN Carbon Market

January 13, 2025 By EarthWise Leave a Comment

The UN climate conference in November approved an official market for large-scale trading of carbon credits.  This will allow industrial countries to help meet their emission reduction targets set by the Paris Climate Agreement by paying other nations to protect and restore forests and carbon-rich peatlands.

The first major participant in this multi-billion-dollar enterprise is Indonesia.  That country is home to the world’s third largest expanse of tropical rainforests and more than a third of the world’s carbon-storing peatlands.  Indonesia’s government plans to raise up to $65 billion by 2028 by selling carbon credits accrued by restoring and protecting its forests and peatlands.

The problem with carbon trading is that it can be filled with loopholes ranging from inaccurate carbon accounting to outright fraud.  Carbon trading with both individual companies and other countries can result in double- and even triple-counting of the same carbon.

For example, carbon credits are assigned when forests earmarked for agricultural or other development are preserved instead of being felled.  But what if that forest destruction wasn’t going to happen even without selling carbon credits? 

There are organizations in the business of verifying carbon accounting, but independent analysis of their methodologies has revealed serious shortcomings, and in many cases, the verifications have been deemed to be worthless.

There are real problems with carbon accounting and setting correct baselines for the carbon emission reductions associated with carbon credits.  Nevertheless, the existence of a global carbon market can be an important tool in the world’s efforts to mitigate the effects of climate change.

Biochar and carbon

April 25, 2024 By EarthWise Leave a Comment

Biochar is a charcoal-like substance that is made by burning organic materials like crop and forestry wastes in a controlled process called pyrolysis, which is burning in an oxygen-deprived environment.  Pyrolysis produces little or no contaminating fumes and results in a stable form of carbon that can’t easily escape into the atmosphere.  Biochar is a very efficient way to convert carbon into a stable form.

Adding charred biomass to improve soil quality has been done for thousands of years.  Indigenous people in the Amazon added charcoal, food residue, and other waste to their soil.  When mixed with soil, biochar creates favorable conditions for root growth and microbial activities, which reduces greenhouse gas emissions. 

Last year, 125,000 tons of carbon dioxide were removed worldwide in the durable carbon market, which is a carbon credit marketplace for carbon removal.  About 93% of that was in the form of biochar. 

Biochar represents a value-added way to deal with agricultural waste and also to make use of dead trees in forests that should be removed to lower the risk of wildfires caused by the presence of all that dry tinder material. 

A bill to fund biochar research is pending before the Senate Agricultural Committee.  It is a rare example of bipartisan legislation.

Biochar is currently expensive to make in the US because large amounts of biomass must be shipped to one of the fewer than 50 small-scale production facilities in the country.   But with appropriate infrastructure, biochar could play an important role in efforts to sequester carbon and combat climate change.
