25zero is a project that involves mountaineering, monitoring equatorial glacial melt and raising awareness of the impacts of climate change. In the run-up to the 27th UN climate conference in November 2022 in Egypt, the green mountaineering project will launch an expedition in June 2022 to Mount Kilimanjaro. Africa’s highest peak is known for its summit ice cap, which has been shrinking rapidly since the beginning of the 20th century and is expected to disappear completely by 2040.
