It took lawmakers in the European Union more than five years to design a new regulation on data protection, the so-called General Data Protection Regulation (GDPR). At last, it becomes active on 25th May 2018. With the GDPR, data protection has been modernised for the ever-changing 21st century. It will give citizens control over their own information, and smaller businesses will have an advantage over big international ones. This is cause for celebration on 25th May, and we look at why this is a win for Greens and the public.
