On the basis of already existing cross-border e-government pilot services and other EU initiatives, the study aims to explore and substantiate the existing and future needs (including socio-economic, environmental, legal and even sector-specific needs) and demand for cross-border e-government services. It will carry out an in-depth quantitative and qualitative cost-benefit analysis to demonstrate how cross-border e-government services can make mobility in the EU less burdensome, provide added value to citizens and businesses and why deployment of new cross-border public services is needed. The study will identify and assess the organisational, legal, technical and semantic barriers that hinder the deployment of cross-border e-government services in the EU and consider their solutions. As a conclusion, the study will identify and propose options for the development of cross-border public services with the highest potential impact.
