She has addressed political leaders and taken part in major climate-related events, and her activism has been widely covered by international media, drawing both support and criticism.

Supporters credit her with increasing public attention to climate issues and youth activism, while critics have questioned her rhetoric, methods, and role in political debate.

She has received numerous honours, including inclusion in Time's 100 Most Influential People and being named Person of the Year in 2019.
