The European Union (EU) is now discussing a legislation proposal to ban illegal timber from the EU market. We use the ICES model to estimate the reallocation of global demand and timber imports following the EU legislation. We aim to assess the economic impacts and measure the potential emission reduction resulting from the introduction of this policy. Results show that an EU ban targeting only log imports is not effective in reducing illegal logging, but its main effect is the removal of illegal logs from international markets. Additionally, the unilateral EU ban increases secondary wood production in illegal logging countries as their exports become relatively more competitive. Through this mechanism, part of the banned illegal timber will re-enter international trade flows 'hidden' as processed wood. Extending the ban to timber processed products eliminates this effect and reinforces direct carbon emissions reduction from logging activities.
