Disagreement about objectives Concerns about “flooding the market” GHG mitigation benefits cannot be measured directly,20,Conclusions,The leading approach to forest offset accounting has been discussed for more than a decade but has not overcome political and technical barriers.Consideration should be given to alternative approaches including “activity accounting.”,21,
