World Environment Day, 5 June

The theme for World environment Day 2026 is “Climate action”, with the official campaign slogan “Inspired by Nature. For Climate. For our Future”. The slogan captures the urgency to address climate change for the sake of all life forms in our common home.

The Earth is already speaking to us—through record-breaking temperatures, more intense wildfires, extreme storms and glaciers disappearing before our eyes.

For years, we have said that limiting global warming to 1.5°C is essential to avoiding the worst impacts of climate change. Today, that threshold is dangerously close to being exceeded—and every fraction of a degree matters.

Climate change is no longer a future threat: it is reshaping life across the planet.

Yet another force is also gaining momentum: collective action. Communities are restoring ecosystems. Young people are driving change. Clean energy is transforming cities and homes. Sustainable solutions are already building a different future. Each of us must take action and make our contribution for all our sakes - human and non-human
