Study Says Relentless Deforestation Demands New Carbon Credit Accounting
Estimation-based protocols cannot fully account for net forest carbon, calling into question the value of carbon credits and benefits to manage global warming, according to a study illustrating a direct measurement approach
"The upshot of the study is that it calls into question the validity of estimation-based commercial forest carbon credits worldwide, absent a full carbon accounting that can be verified by direct CO2 measurement—
The problem is that existing protocols cannot fully account for net forest carbon, a metric of benefit to the atmosphere that balances carbon uptake by photosynthesis and carbon release by respiration. Limited measurements of forest biomass, exclusion of actual CO2 measurements and reliance on vegetation growth models are employed worldwide, including by the California Air Resources Board, the Climate Action Reserve, the American Carbon Registry, and the UN Reducing Emissions from Deforestation and Forest Degradation (UN-REDD+), despite the risk of invalidation by direct measurement, according to a recent study, also co-authored by PEM.
"We have lost our way in the forest, blinded by large-scale umbrella policies devoid of mandates for actual measurement of forest CO2 and truly independent verification of net CO2 reduction claims; scientific challenge to these protocols and policies appears to be the only way to lay bare the issues," remarked Marino.
Solutions to slow and stop deforestation are hiding in plain sight, including universally accepted forest carbon science and measurement methods, such as eddy covariance, deployed worldwide in over 600 locations, to determine net carbon sequestration, or net ecosystem exchange. However, established research methods have not been used for commercial applications as illustrated by the study.
