As part of # global-donut-days hashtag_lookup:#global-donut-days a diverse group of changemakers came together in the city of Vienna to apply the four lenses framework and discuss what it would take to move the city towards the Doughnut. The event marked the launch of our initiative Doughnut4Wien and the creation of a new grassroots organisation aiming to create a Doughnut for the city of Vienna and use it to influence organisations and policymakers.
