Helping WHO build trust through health communications

Our work supported communications on climate action around three key pillars: promoting co-beneficial actions for health and the environment, building climate-resilient health systems, and protecting populations from climate impacts. Through clear, compelling storytelling, HCS helped translate complex technical themes into accessible narratives for global audiences.

The content included summary videos, vox pops, and explainers featured on WHO’s corporate and leadership channels. The content amplified high-level discussions, showcased ministerial commitments, and inspired engagement from youth and civil society. These projects demonstrate HCS’s proven ability to communicate environmental and public health priorities with creativity and impact, positioning climate and health as interconnected foundations of sustainable development.

HCS-produced videos and social content were shared across WHO’s official channels, reaching over 60 million followers (11.8M on Instagram, 12.1M on X, and 37M on Facebook), with further amplification through the WHO Director-General’s accounts, followed by 2.3 million more. This global distribution ensured broad visibility and engagement across regions, amplifying WHO’s health and climate messaging among policymakers, media, and civil society.
