BAKU, Azerbaijan|June 2026 – With global temperatures near record highs and El Niño set to return, governments, businesses, and communities marked World Environment Day 2026 on Friday 5th, with urgent calls for climate action.
Azerbaijan hosted the official global commemoration in Baku. Extreme heat is one of the deadliest and fastest-growing climate threats to lives, livelihoods, and economies. With the Paris Agreement’s 1.5°C limit likely to be temporarily breached, UN Secretary-General António Guterres said the priority now is to limit the damage.
“This World Environment Day, warning signals are everywhere. The past eleven years have been the eleven hottest on record… The world is heading for a temporary overshoot above 1.5 degrees,” Guterres said.
“Our task is to make that overshoot as small, as short, and as safe as possible and rapidly bring temperatures back down.”
He called on nations to cut emissions, accelerate a just transition from fossil fuels to renewables, reduce methane emissions, protect forests and oceans, support communities to adapt, and deliver promised climate finance to developing countries.
As host, Azerbaijan pledged to nearly double renewable energy capacity by 2030 and implement a climate plan aligned with 1.5°C. The country also committed to a 40% reduction in emissions by 2035 and 30% renewable energy by 2030. Azerbaijan faces severe climate impacts itself, including the shrinking of the Caspian Sea, the world’s largest inland water body.
The nation has taken a leading role in climate diplomacy after hosting COP29 and the recent World Urban Forum.
“This year’s focus on climate action could not be more timely,” said Rashad Ismayilov, Azerbaijan’s Minister of Ecology and Natural Resources. “The science is clear: every fraction of a degree of warming costs lives, livelihoods, and ecosystems, and no country is spared.”
UNEP Executive Director Inger Andersen said World Environment Day is about turning warnings into action. “We can craft our own story by acting to slow and adapt to climate change… But it will take all of us,” she said.
More than 2,000 World Environment Day events were registered worldwide. Highlights included heat action, with more than 50 cities from Lagos to Paris participating in UNEP’s “50@50” initiative to share solutions for extreme heat and sustainable cooling. It involved digital activities such as Editathons in Santiago and Nairobi, which added 15 new Wikipedia articles, 511 references, and 69,500 words on climate.
