Satellite Study Reveals Uselessness Of CA "Carbon Offsets"; Logging Marches On, No Net Capture
Many of the companies promising net-zero emissions to protect the climate are relying on vast swaths of forests and what are known as carbon offsets to meet that goal. On paper, carbon offsets appear to balance out a companys carbon emissions: The company pays to protect trees, which absorb carbon dioxide from the air. The company can then claim the absorbed carbon dioxide as an offset that reduces its net impact on the climate.
However, our new satellite analysis reveals what researchers have suspected for years: Forest offsets might not actually be doing much for the climate. When we looked at satellite tracking of carbon levels and logging activity in California forests, we found that carbon isnt increasing in the states 37 offset project sites any more than in other areas, and timber companies arent logging less than they did before.
The findings send a pretty grim message about efforts to control climate change, and they add to a growing list of concerns about forest offsets. Studies have already shown that projects are often overcredited at the beginning and might not last as long as expected. In this case were finding a bigger issue: a lack of real climate benefit over the 10 years of the program so far.
EDIT
Ironically, while intended to help mitigate climate change, forest offsets are also vulnerable to it particularly in wildfire-prone California. Research suggests that California is hugely underestimating the climate risks to forest offset projects in the state. The state protocol requires only 2% or 4% of carbon credits be set aside in an insurance pool against wildfires, even though multiple projects have been damaged by recent fires. When wildfires occur, the lost carbon can be accounted for by the insurance pool. However, the pool may soon be depleted as yearly burned area increases in a warming climate. The insurance pool must be large enough to cover the worsening droughts, wildfires and disease and beetle infestations.
