From 28 September to 2 October, Milan hosted the proceedings of the Youth4Climate, the conference of 400 young delegates, and of the pre-Cop26. Two pivotal moments in the run-up to the historic Cop26 in Glasgow — the United Nations climate conference that is expected to secure a stronger commitment from the international community to cutting CO2 and greenhouse gas emissions in the fight against the climate crisis.

They were intense days, during which young people tried to make themselves heard as much as possible, both inside and outside the walls of Milan's convention centre. Inside, activist delegates pressed international leaders in every way possible to abandon all fossil fuels — not just coal — by 2030. Outside, 50,000 students joined the climate strike on 1 October, complete with a march that wound through the streets of Milan. A river of young people who had a clear goal in mind: climate justice. And a clear timeline for achieving it: now.

Among the 50,000 were the international leaders of the Fridays for Future movement. Three young women: Milan's own Martina Comparelli, Sweden's Greta Thunberg, and Uganda's Vanessa Nakate.

We followed the week's events in the city step by step. And the result is captured in full in this video, which we hope will give you too the enthusiasm and hope needed to reach the finish line. Because another world is not only possible — it is necessary.
