The purpose of this study is to analyze the current status of the wood material demand in Taiwan for the references of forestry policy-making, academic research and CO2 sequestration estimation. By using the classification definition of the harvested wood product of FAO, the wood product groups were reclassified and estimated, including roundwood, sawnwood, wood based panels and pulp wood and wood chips. According to solid wood equivalent volume, the total wood material demand and consumption were estimated. In 2011, wood product demand is 5.29 million m^3, the consumption is 5.20 million m^3. However, the wood self-sufficiency rate is only 0.45%. The demand difference between solid wood equivalent volume and round wood equivalent volume is 3.29 million m^3.
