Abstract
This paper provides an innovative approach to assessing carbon sequestration in sweet chestnut coppice
taking into account the importance of carbon fluxes in the whole forest-industry value chain in the
mitigation of climate change. The goals of this study were: to evaluate the baseline carbon capture of
sweet chestnut forest in the north of Spain; to assess the effect of thinning and extending the rotation
period on carbon storage; and to evaluate the substitution effect of using sweet chestnut products as an
alternative to other materials. The CO2FIX model was used to estimate carbon content in different forest
components: aboveground and belowground biomass, soil and wood products, under five different
thinning and rotation scenarios. Model parameterization as a function of stand age was carried out using
growth data, climate data, litterfall rates, sawmill processing data, and data on the lifespan of products
and their final end. Sawmill efficiency was measured in situ using the Lumber Recovery Factor.
The scenarios in which only one thinning was made resulted in more total carbon accumulating than
the baseline, especially when the 40 years rotation was increased by 20 years. In contrast, scenarios
involving two thinning did not even reach the baseline value of total carbon. Additionally, a positive
impact on GHG emissions was found for using wood to substitute other materials, i.e. cement and fossil
fuel. Taken together, these results highlight the sustainability of thinning and rotation treatments in
terms of carbon storage in sweet chestnut coppice, and quantifiably supports the environmental benefits
of the substitution effect of sweet chestnut wood products. As such, it provides valuable information for
forest managers and policy makers who wish to address climate change mitigation in forest management
planning.
