you will find draft versions of the Horizon 2020 work programmes for 2016-2017. These documents are being made public just before the adoption process of the work programme to provide potential participants with the currently expected main lines of the work programme 2016-2017. They are not yet endorsed by the Commission and they do not in any way prejudge the final decision of the Commission.
