The present Green Paper forms part of the Digital Strategy 2025, the broad outlines, measures and goals of which were published by the German Federal Ministry of Economic Affairs and Energy at the beginning of March this year. It marks the prelude to a broad discussion. It identifies, defines and correlates the legal and regulatory questions that need to be asked on the issue of digitalisation. The aim is to establish a regulatory framework to facilitate more investments and innovations based on fair competition, while also assuring basic individual and corporate rights and data sovereignty. Success or failure in this task will have a decisive effect on how far digitalisation can enter the mainstream of economic and social life, gain acceptance and be grasped as an opportunity.
