World Environment Day Belgium

Plastic pollution permeates every corner of the planet, even in our bodies in the form of microplastics. The #WorldEnvironmentDay 2025 campaign, calls for collective action to tackle plastic pollution.

By drawing inspiration from nature and showcasing real-world solutions, the campaign encourages individuals, organizations, industries, and governments to adopt sustainable practices that drive systemic change.

This year’s World Environment Day (5 June) comes exactly two months before countries meet again to continue negotiating a global treaty to end plastic pollution.

Join the UN Environment Programme (UNEP)-led #BeatPlasticPollution campaign! Find out how here.
