New technologies have significantly entered our lives and online services offer the opportunity for sustainable regional development. Electronic services offered by the new Information and Communication Technologies (ICT's), have proved an important tool in efforts to disseminate e-learning in modern education during the pandemic especially in confinement. E-Learning is the delivery of learning and training via digital resources. E-Learning is based on formalized learning and it is provided through electronic devices such as computers, tablets and even smartphones that are connected to the internet. The global pandemic has drastically changed the way that people learn worldwide. Citizens, experts, students from all around the world have suddenly shifted from classroom learning to online learning. This type of learning that is independent of place and time, extends learning to people around the world. This paper describes seminars that took place online in the framework of LIFE CLIVUT project (Climate value of urban trees-LIFE18 GIC/IT/001217).
