Why in news?
World Environment Day is celebrated every year on 5 June, and in 2026 the United Nations Environment Programme (UNEP) has dedicated the observance to the theme of climate action. The Republic of Azerbaijan hosts the global celebrations in its capital, Baku, with the campaign message “Now For Climate”.
Background
World Environment Day was established by the United Nations General Assembly following the 1972 Stockholm Conference on the Human Environment. The first celebration took place in 1973 under the theme “Only One Earth”. Since then, the day has grown into a global platform for public outreach, raising awareness and prompting action on pressing environmental issues. Each year a different country hosts the main event and selects a theme.
In 2026 UNEP asks governments, businesses and individuals to focus on climate change. The campaign highlights the signals the planet is sending – rising temperatures, melting glaciers, wildfires and droughts – and calls for urgent action to reduce greenhouse‑gas emissions. The host nation Azerbaijan complements the global message with a national theme, “Inspired by Nature. For Climate. For Our Future.” The country is pursuing green growth through renewable‑energy projects, electric buses and conservation initiatives, and also hosted the UN Climate Change Conference (COP29) in November 2024.
