Abstract Environmental transition is increasingly governed through multilevel systems in which authority is shared across supranational, national, and regional governments. Existing research on multilevel climate governance has focused on coordination, implementation, and compliance, largely treating environmental objectives as politically consistent among territorial levels once adopted. This paper argues that multilevel governance also reshapes the political content of environmental transition itself, a process we call political reinterpretation: common climate objectives are selectively reprioritized and reframed as they enter territorially distinct political arenas. We test this argument using text analysis of parliamentary discourse, applying structural topic modeling to 10,564 speeches delivered across Spain’s seventeen Autonomous Communities (ACs) between 2019 and 2024 to uncover five substantive dimensions of environmental-transition discourse directly from legislative text. We find that these dimensions are distributed unevenly across regions, and, more critically, that Spain’s major statewide parties do not reproduce their national environmental-transition profiles across territories: territorial variation in the topics they prioritize within each party systematically exceeds the variation observed between parties operating in the same region. This pattern holds even among parties whose organizational structure gives them a strong incentive toward national uniformity, indicating that territorial incentives can outweigh the integrative pressures of statewide party organization. Understanding climate governance in decentralized systems therefore requires attention not only to how environmental policy is implemented across levels of government, but to how its political meaning is reconstructed as authority becomes territorially dispersed.
