Integrating the theory of planned behavior (TPB) and the norm activation model (NAM), this study investigated the formation mechanism of university students’ willingness-to-pay (WTP) for carbon offsets under climate change. Through a survey of 2728 students across 28 universities in Yunnan Province, China, we developed an extended TPB-NAM framework incorporating carbon offset cognition (COC), climate change hazard perception (CCHP), and climate change awareness (CCA). Key findings revealed the following. (1) The integrated model explained 74.8% of WTP variance (R2 = 0.748), with behavioral attitude (β = 0.467, p < 0.001), subjective norms (β = 0.297, p < 0.001), and COC (β = 0.087, p < 0.001) emerging as primary direct predictors. (2) PN exerted the strongest indirect effect via ATP (β = 0.223, p < 0.001), while full mediation occurred between AC and WTP through ATP/PN. (3) Counterintuitively, CCHP demonstrated significant negative impacts (β = −0.027, p < 0.01), revealing nonlinear risk perception–behavior relationships. This research pioneers the application of TPB-NAM synthesis in carbon offset studies, proposing a tripartite intervention framework (“value identity–social norms–cognitive drive”) for campus carbon neutrality policies. The results advance voluntary carbon market mechanisms through theoretical integration and contextualized behavioral insights.
