Collaborating with Rewriting Earth, we developed a creative framework for the UNEP 'Sports for Nature' initiative, to kick start a global movement against climate change. Our brief was to bridge the gap between high-level policy and public engagement, designing an adaptable visual system for a diverse network of 140+ sports signatories. We delivered an extensive activation toolkit, scroll-stopping social media content, and seamless digital guidelines. Launched globally on World Environment Day 2025, the campaign successfully transformed complex environmental targets into high-impact, shareable assets that empowered world-class sporting bodies to demonstrate their ecological commitment and mobilise their communities.
