Johannes Brehm

Researcher RWI – Leibniz Institute for Economic Research

My research investigates how environmental policies reshape economies and societies. I study how carbon pricing, transport regulation, and climate risks affect innovation, health, and inequality, and how people perceive and respond to climate action. Using rigorous state-of-the-art empirical methods, I aim to identify policies that are both effective and socially equitable.
