The Swiss voice in the world since 1935

Kristian Foss Brandt

I cover climate and sustainability topics with a data-driven perspective. Trained as a journalist but working as a data scientist, I combine storytelling with analysis to uncover the facts behind Switzerland’s green transition. At SWI swissinfo.ch, I focus on how climate change affects daily life and what solutions can make a difference. I am passionate about exploring practical ways to reduce our environmental footprint and inspire others to do the same.
