Xavier Cortada implemented the HELLO participatory art project with attendees of COP26 from November 1st – Nov 12th. This page showcases the project through images and videos, connecting those on-site with the global community online. Thousands of people from across the world who attended COP26 wore HELLO stickers in a collective effort to catalyze conversations around climate action, urge world leaders to meaningfully address the climate crisis, and ultimately turn it around.
