The objective of the project has been to generate Easy-to-use tools for Nordic environmental authorities, providing them with guidance on what terms can be used when formulating BAT and CT conditions in the permit and licensing process. The tool can also be used as a guide to industries applying for permits. This report, Part 1, contains a summary of findings, analysis and conclusions of the project. There are two other reports from the project: "Part 2: Surface treatment of metals" and "Part 3: Fish processing industry" which give overviews of BAT, CT and Easy-to-use tools for the two specific sectors. The project has looked into common processes and production technologies for each of the sectors, and their main environmental impacts. Investigations on relevant permit requirements have been carried out in Denmark, Iceland, Norway and Sweden. The report compiles the common terms used in Nordic permits and summarizes experiences concerning BAT and CT requirements. The BAT and CT requirements identified in the Ease-to-use tools are separated into various themes to ease the user's identification of relevant information.
