Namugerwa heard of Greta Thunberg and her Friday strikes in 2018.[1] She was later inspired to take similar action as Greta Thunberg at 13, after she watched a local news report about mudslides and flooding in rural sections of the country.[2] Namugerwa has since become a prominent young climate advocate and an integral member of Africa’s most prominent chapter of Fridays for Future taking place in Uganda.[5][1] She teamed up with Sadrach Nirere, Hilda Flavia Nakabuye, and her cousin Bob Motavu to birth the Fridays for Future Uganda. She has been engaged in Friday striking since February 2019, calling for more climate actions, and she has led the writing of a petition to enforce the ban of plastic bags.[1][9]
