Achieving carbon neutrality will require the redirection of harvested wood towards long-life uses. To achieve carbon neutrality, France is relying on its carbon sink to balance residual emissions in 2050. A smaller carbon sink would require even greater emissions reductions from other sectors (transport, agriculture, industry, etc.), sectors in which France is already calling for drastic sixfold cuts between 1990 and 2050. In a context where the carbon sink in ecosystems is already falling sharply due to an increase in tree mortality, preserving this sink and developing carbon storage in wood products must be a major concern of the national climate policy.

To achieve the climate goals of the UE, The European Commission wants to create a carbon certification framework to encourage carbon storage in the land sector. The challenge is to develop a common and harmonised framework at the European level by better relying on the expertise acquired through existing certification frameworks. With this study, I4CE propose 7 recommendations, inspired by both our concrete experience with the French Label Bas-Carbone to which we have contributed, and by 15 years of research on carbon certification.

In addition to debates about the right level of wood harvesting, another issue is equally crucial from a climate point of view: what is the best way to use the harvested wood? France’s long-term strategy, the Stratégie nationale bas-carbone (SNBC), calls for an increasing proportion of wood to be directed towards long-life wood products such as those used in construction, which store carbon for long periods. The aim is to redirect part of the resources currently dedicated to shorter uses, such as paper and energy production, towards these longer-lasting uses. While the objectives are very ambitious, the strategy does not come with the policies needed to achieve them. I4CE has therefore assessed the technical feasibility of redirection of the wood use, and has identified the most promising production chains of long-wood products.

The French National Low-Carbon Strategy (SNBC) aims at doubling the volume of CO2 removals thanks to the contribution of the forest-based sector, the agricultural sector and the geological carbon capture and storage technologies. The projections concerning these compartments and the underlying technical assumptions have been explored and compared to the existing literature in an in-depth analysis, with the goal of clarifying the challenges and conditions for this massive increase in carbon removals. The conclusions are that far-reaching changes are required in the different sectors and that some objectives for the forest-based sector may be impossible to achieve.
