Illegal logging โ the harvesting, processing, and trading of timber in violation of national and international law โ is estimated to account for between 15% and 30% of global timber trade, generating revenues of between $50 billion and $150 billion per year. It is one of the world's largest environmental crimes, driving deforestation in some of the most ecologically sensitive forests on the planet, undermining legitimate forestry businesses, depriving governments of billions in tax revenue, and funding corruption and organised crime in affected countries.

Illegal logging takes many forms. At the smallest scale, subsistence communities may harvest timber from protected areas for personal use or local sale. At the largest scale, organised criminal networks engage in systematic extraction from national parks and indigenous territories, falsifying documentation to launder illegally harvested timber into legal supply chains. Between these extremes, a spectrum of illegality exists: logging with permits obtained through corruption, harvesting protected species, exceeding licensed harvest volumes, or operating in areas where permits were issued unlawfully.
The key mechanism that enables illegal logging to persist is the laundering of illegal timber into legal supply chains. Once illegally harvested logs are mixed with legally harvested timber at a processing facility, and accompanied by fraudulent documentation, they become effectively untraceable. Consumer countries โ particularly in Europe, North America, and increasingly China โ import billions of dollars of illegally sourced timber annually, often unknowingly. Legislation like the EU Timber Regulation and the US Lacey Act attempt to require due diligence in timber supply chains, with some success, but enforcement remains challenging.
