The People behind Climate Justice for Rosa vzw
The Climate Justice for Rosa campaign was launched by Benjamin Van Bunderen Robberechts shortly after Rosa’s death, when he was just 14 years old. He quickly garnered the support of Rosa’s friends and family. After about two years of activism, it became clear that legally formalising the organisation was necessary to amplify its impact.
Climate Justice for Rosa is, and remains, a youth-led organisation. The day-to-day running of the organisation, the campaigns we choose, and the ideas we defend are all in the hands of Rosa’s friends, our Campaign Leads. They are the young people who shape and drive everything we do.
Over the years, many individuals with diverse expertise have contributed to the campaign in a variety of ways. To support the youth leadership, the board of our non-profit consists of individuals authorised by Rosa’s family. They serve in advisory and governance roles, offering legal, scientific, and strategic guidance. Their role is to help steer and safeguard the organisation, while the day-to-day decisions and direction remain with the Campaign Leads.
