- Criticism of voluntary carbon trading and forest conservation strategies such as REDD+ has focused mainly on the carbon accounting methods used to calculate credits.
- Each credit traded on voluntary markets is supposed to represent the reduction, avoidance or removal of 1 metric ton of carbon dioxide from the atmosphere.
- However, recent science has raised questions about how REDD+ and other types of projects measure the number of tonnes of emissions saved.
- The process relies on establishing a baseline deforestation rate against which the project's success in reducing or eliminating emissions is measured. But critics say the process can be flawed and that conflicts of interest among parties involved in setting the baseline have not been addressed until recently. (John Cannon)
