This study examines the possibilities to monetize on carbon markets four types of actions through which the forestry and wood sector can mitigate climate change: - Increasing the carbon stock in the forest - Increasing the carbon stock in wood products - Using wood as a substitute for fossil fuels (wood for energy) - Using wood as a substitute for materials more energy intensive (wood as a material) Actions of the "stock increase" type can theoretically be valued on the voluntary carbon markets. Developments are nevertheless necessary to make these valuations operational. Mechanisms of the "substitution" type can be valued only on the compliance market. They are currently valued at the level of the user (electric power generation, heating etc.); the forestry and timber industry can only participate in this system via agreements such as "supply contracts". - This report analyses three project types that could be carried out to activate these mechanisms: - Reforestation / Avoided deforestation - Improved forest management - Optimized utilization of products On the basis of seven hypothetical projects, this study identifies a strong carbon sink potential in France (several million metric tons of CO2), including afforestation, the conversion of coppice forest into high forest and the changes in the uses of harvested wood. Carbon certification is expensive and makes sense only above a critical size that enables project developers to recover their expenses. For reforestation projects in metropolitan France, for example, we estimate this size to be around 100 hectares. Several certification programs coexist on the voluntary carbon market. Their pertinence to the seven hypothetical projects is also analyzed, together with the conditions for carbon credits generated in the French forestry and wood sector to be monetized on carbon markets. To achieve this, two conditions need to be met: methodologies approved by standards should be developed, and the forestry and wood sector should implement a proper organization.
