How ideas shape the EU's climate policy: Moving toward the sufficiency paradigm for the EU ETS

Abstract This article examines the paradigm shifts in the European Union's (EU's) climate policy from 2009 to 2022 looking closer at the main policy instrument of EU's climate policy, the EU Emissions Trading System (EU ETS). The paradigm shifts of the EU ETS are linked to the climate policy paradigms prometheanism/growth unlimited (PGU), ecological modernization (EM), and sufficiency. The question of how ideas have shaped EU climate policy and the EU ETS in the past decade is answered, with the establishment of the EM paradigm and moving toward the sufficiency paradigm. There is a need for more research looking closer at how this paradigm shift impacts legislation for climate policy going forward.
