The carbon mitigation potential after 20 years varied between 8.2 and 19.3 t C/ha for the oak conservation scenario and between 21.6 and 42.9 t C/ha for the oak conservation–bioenergy scenario. The bioenergy scenario results in a continuous stream of about 1.36 t C/ha of carbon benefits per year, whereas the oak conservation scenario will stop accumulating carbon after 40 years, compared to current forest management and energy generation.

"Key to climate change abatement strategies is the understanding of the comparative carbon mitigation implications of management of native forests oriented to different end-uses such as conservation, conventional management, or integrated management that includes bioenergy.
