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.

Blue carbon credits and the fight against climate change

Carbon credits have been around since the late 1990s.  The idea is to offset carbon emissions from some carbon emitting activity – anything from a wedding in California to a factory operating in Minnesota – by buying carbon credits earned from a carbon-absorbing activity, such as planting trees in the Amazon.

Blue carbon credits are credits earned by increasing the carbon stored in coastal and marine ecosystems. Coastal ecosystems such as mangroves, tidal marshes, and seagrass meadows in fact sequester and store more carbon per unit area than terrestrial forests and are increasingly being recognized for their important role in mitigating climate change. 

Blue carbon credit awards have to date been relatively few and far between and have mostly been granted for mangrove restoration efforts.  But mangrove projects are now ramping up dramatically in scope.  Scientists are working hard to analyze the amount of carbon in other ecosystem types – seagrasses, salt marshes, seaweeds, and seafloor sediments – so that these systems can also enter the carbon credit market.

Over the past 20 years, conservation scientists have spread over 70 million seeds in the bays of Virginia to restore over 9,000 acres of seagrass meadows that were devastated by disease in the 1930s.  The restored meadows are absorbing nearly half a ton of CO2 per acre. 

The rules to allow for blue carbon credits are recent and evolving, which is a big deal. The market may currently be small, but it is growing exponentially.  But as important as carbon credits are, it is still paramount to decarbonize before turning to offsets for existing emissions.

Trees are the number one way in which carbon can be removed from the atmosphere and stored in vegetation over the long term.  A single tree can absorb CO2 at a rate of 48 pounds per year.  Because of this, the carbon footprints of 18 average Americans can be neutralized by one acre of hardwood trees.  And it has been found that managed forests accumulate more carbon per acre than unmanaged forests.

Many people compost their food scraps and yard waste because they think it is the right thing to do.  In some places, like San Francisco and Seattle, there is curbside pickup available to have these organic materials composted.
