Resumo: Despite sustained interest in sustainable tourism, the gap between environmental concern and travel behavior is still often explained as an individual failing. This article develops an integrative conceptual review and synthesis of behavioral, discursive, organizational, household decision-making, environmental ethics, and political-economic studies to reframe this gap as a multilevel condition of environmental incoherence. The proposed model explains how values, household negotiations, platform-mediated choices, institutional incentives, and mobility regimes interact to produce and stabilize misalignment between environmental commitments and travel practices. Its main contribution is a diagnostic framework that distinguishes temporary inconsistency from structurally reproduced incoherence, identifies the mechanisms through which incoherence circulates across micro-, meso-, and macro-levels, and clarifies which institutional levers may strengthen alignment between sustainability discourse and material mobility practices. © 2026 The Authors
