When COP26 was postponed, due to the global Covid-19 pandemic in 2020, over 330 youth delegates representing over 140 countries gathered online at Mock COP26. It was a powerful statement showing the ambition and dreams of young people worldwide fighting for a fair, equal and green world. The conference culminated with a global declaration to world leaders with 18 ambitious, yet realistic policies covering 6 important themes; climate education, climate justice, climate-resilient livelihoods, physical and mental health, nationally determined contributions and biodiversity. Mock COP delegates are now mobilising a movement of young people globally campaigning for their leaders to show this ambition and implement parts of our treaty. Mock COP has gained international recognition and demonstrated the power of youth mobilisation to gain a seat at the table at COP26 in Glasgow in 2021, and now COP27 in Egypt in 2022, see phase 2 and phase 3 activities for more information.
