Contributions of China’s Wood-Based Panels to CO<sub>2</sub> Emission and Removal Implied by the Energy Consumption Standards

Life cycle analysis on wood-based panels in terms of CO<inf>2</inf> flux can be used to quantitatively assess the climate change contributions of these materials. In this study, the annual CO<inf>2</inf> flux between 1990 and 2015 was calculated through gate-to-gate life cycle analysis of wood-based panels. As implied by the energy consumption standards, China’s wood-based panels used to be carbon sources during the period 1990–2007, with the average contribution to CO<inf>2 </inf>emissions of 9.20 Mt/year. The implementation of new standards and the development of Cleaner production technologies in China, decreased the energy consumption per panel. China’s wood-based panels acted as a carbon sink between 2008 and 2015, with the average contribution to CO<inf>2</inf> removal of 31.71 Mt/year. Plywood produced the largest contributions to the emission and removal of CO<inf>2,</inf> and was followed by fiberboard and particleboard. China’s wood-based panels, with good prospects and strong demands projected in the future, can potentially contribute to climate change mitigation.
