报告摘要

Forest and wood products present four assets to help mitigating climate change: carbon capture and carbon storage, making forests one of the largest carbon sink, and material and energy substitution. In managed forests, carbon storage depends of course on long term management. Wood products on the market are also a significant carbon pool, with an entering flux of carbon from forest embedded in new products and an outing flux with end-of-life waste products management. When this stock is growing wood products become a carbon sink.
From the European and French perspectives, forest represent today the largest carbon sink compared to wood products on the market. Nevertheless, in the perspective of a climate change mitigation strategy over the coming decades, it is important to consider the dynamics of these sinks and also the substitution effects of increasing the use of a lower carbon intensity material and energy source than the dominant ones.
 In this presentation, the figures, the importance and the drivers of the forest and wood products carbon sinks are considered, taking as example the French situation. The importance of both material and energy substitution effects is also discussed. The prospects for the potential benefits of policies and strategies maximizing these effects are also exemplified on the basis of the French situation. For these policies implementation, methodological choices in environmental accounting tools are important in order to acknowledge the benefit of carbon storage in long life wood products. Then, the challenges with these strategies for obtaining the best effects of these levers for climate change attenuation are discussed. In a context of strong market competition with other materials, some possible ways of overcoming these challenges are presented.
