GTL, Green Transformational leadership; VC, Value congruence; GI, Green identity. All alternative models were compared with the hypothesized three-factor model. CFI, comparative fit index; TLI, Tucker-Lewis index; SRMR, standardized root mean square residual; RMSEA, root mean squared error of approximation. ∗∗∗p < 0.001.
