In Peru, the National Pact for Legal Wood was signed in December 2014 by five government agencies, indigenous peoples’ federations, the private sector, and nonprofits. Under this agreement, parties committed to promoting trade in legal timber and to eliminating illegal logging in the country by 2021. Technology is being explored that can improve timber traceability and prevent illegally harvested wood from being passed off as legal. This includes attaching plastic tags to harvested logs with laserprinted QR codes that are smartphone-scannable. The QR code provides data on species, volume and geographic origin. What other tools exist that can increase transparency in timber supply chains?
