EuropaCat 2027 presents catalysis as a genuinely multiscale science, ranging from atomic-level understanding to industrial implementation and societal impact. The congress programme traces the catalytic journey from fundamental insight and advanced characterisation, through catalyst and process design, to applications essential for the energy transition, environmental protection, and the circular economy. Particular emphasis is given to catalytic solutions that support sustainable energy systems and environmental stewardship.
