In order to improve understanding of European Grouping of Territorial Cooperation (EGTC) instruments, a Good Practice booklet, released in July 2018 and available here, provides examples of cross-border projects within the EU. The EGTC instrument was introduced in 2006 to overcome barriers when integrating territories and is an instrument which establishes an international entity under European law. As of December 2017, there were 68 EGTCs in the EU. The booklet highlights the EGTC instrument’s strengths: communication; visibility due to European legal basis; ability to promote local and regional authorities at EU level; better access to information than their individual members; ability to combine multiple functions. The booklet illustrates good practices of 21 EGTCs based on the 2016 and 2017 CoR EGTC monitoring reports.
