The CROSS final event has two main objectives. The first objective is to close the CROSS activity, presenting its main achievements and results. This will also serve as a bridge between the CROSS activity and the new SWEET-Coevolution consortium. The second objective is to have a first in-depth look at the research results that have been achieved in the first 1.5 years of SWEET (EDGE, PATHFNDR, SURE and DeCarbCH).
