World Environment Day 2025 served as a powerful reminder that people everywhere want an end to plastic pollution.

As host of this year’s commemoration, the Republic of Korea underscored its leadership in global environmental diplomacy. Under the theme “Shared Challenge, Collective Action,” the official ceremony brought together delegations from 19 countries and representatives of major international organizations.

UNEP’s #BeatPlasticPollution campaign shed light on the deepening plastic pollution crisis—now infiltrating oceans, soils, and even human bodies through microplastics. The campaign resonated worldwide: from Times Square to Beijing Airport, UNEP’s messages filled billboards and public spaces, while governments rolled out new initiatives, signaling a growing global will to tackle plastic pollution.

The momentum ignited from World Environment Day 2025 will carry forward, continuing to drive action to #BeatPlasticPollution and move us toward a cleaner, healthier world.
