This Research Note presents the outcome of an investigation into the processes of lone-actor terrorism which was part of the Countering Lone-Actor Terrorism (CLAT) Project. The research is based on a database of both plots and attacks across the twenty-eight EU member states, plus Norway and Switzerland, in the period 1 January 2000 to 31 December 2014. The database covers more than 70 variables and includes information relating to 120 individuals. This Research Note outlines some of the key findings of the CLAT project pertaining to 1) attack methodology and logistics; 2) political engagement and online activity and 3) leakage and interactions with authorities. The results relating to the personal characteristics of lone-actor terrorists are presented in a different Research Note in this issue of Perspectives on Terrorism.Security and Global Affair
