Expert consultations — interviews and substantive contributions

All World 3.0 research processes undergo multi-stage external validation. We confront our analyses with the expertise of independent researchers and leading institutions working in climate policy, emissions physics, and regulatory engineering. Through regular expert consultations, we critically examine our underlying assumptions, eliminate the risk of interpretive error, and sharpen the precision of our legislative conclusions. As a result, we deliver solutions that are not only ambitious, but above all grounded in the current state of scientific and legal knowledge.

Ingun Grimstad Klepp

Professor of Clothing and Sustainability, Oslo Metropolitan University

A researcher specialising in clothing habits, textile consumption, and the environmental impact of fashion. Her work spans the relationship between technical, social, and historical dimensions of textiles, with a particular focus on how knowledge about clothing practices can inform policy processes to reduce environmental burdens, including climate impact.
She is affiliated with the Consumption Research Norway institute (SIFO) at Oslo Metropolitan University, where she leads research on sustainable textiles, garment lifespans, washing habits, and the social dimensions of clothing. She is also the founder of the Clothing Research platform (clothingresearch.oslomet.no).
