1. INTRODUCTION COST ACTION E22: Environmental optimisation of wood protection Norway has about 50 pressure treatment plants using CCA-preservatives. Three of the plants use creosote and two the Royal process ® . The treated volume is about 320,000 m 3 (transmission poles: 20,000 m 3 , sawn timber: 250,000 m 3 , other waterborne products: 20,000 m 3 and treated joineries with LOSP: 25,000 m 3 ). About 90 % of the volume are controlled by the national quality control scheme. 86 % of the volume is waterborne salts (CCA), 8 % creosote and 6 % oil borne preservatives. Jotun AS is the only producer of preservatives in Norway. The Norwegian Government has dropped an environmental tax for pressure treated wood, and will instead impose restriction. This information is based on the knowledge received from a survey we did during the work in COST Action E 2. We arranged a meeting with different institutions working with timber constructions, wood preservatives, wood preservation, fungi and remediation in general. All the institutions are located within 20 km from the Oslo centre. 104
