“The industrial revolution of our time is
digital. [...] as companies aim to scale up
across the Single Market, public e-services
should also meet today’s needs: be digital,
open and cross-border by design. The EU is
the right scale for the digital times.”
Andrus Ansip, Commission Vice-President for
the Digital Single Market
