The fourth EUCROWD public event took place in Athens on 9th May 2017. The international conference and workshop “Let’s Crowdsource the Future of Europe” organized by Science For You brought together 47 citizens from 9 different countries. The event focused on how EU decisions are made and in what ways crowdsourcing will allow citizens to participate directly. In particular, participants discussed when crowdsourcing could be used in the legislative process of the EU, what topics should it cover and what tools and methodologies can enhance crowdsourcing by learning from best practices in Greece.
