[3] In Liège, Sarah Schlitz has been involved in grassroots community organizing focusing on ecological, social and feminist politics.

[2] Between 2015 and 2018, she was campaign coordinator at the ecological association Inter-Environnement Wallonie [fr], and from 2016 to 2018 she was co-chair of the Coalition Climat.

[11] In April 2023 she became the centre of a scandal when it was made known that her personal logo had been added to projects that had been funded by her as state secretary,[13] which is illegal in Belgium.

She claimed that she had not asked for this and that the projects had acted on their own initiative, but leaked emails later showed that she had explicitly requested this herself, after which the opposition called for her resignation.

[14] To make matters worse, her cabinet employee shared a message on social media that linked nationalist party N-VA to Nazism.
