Previous studies have well documented the positive association between organizational support and pro-environmental behaviors (PEBs) at work. However, there is limited evidence on their causal relationship. We also know little about whether employees' PEBs at work can be motivated by organizational support in actual working contexts. The present study explores how organizational support influences employees' PEBs at work via multiple methods. Specifically, a cross-sectional survey (pre-study, n = 219), an experiment with a recall paradigm (Study 1, n = 101), and a field study in a company (Study 2) were conducted. The results of the three sub studies consistently indicated that organizational support effectively facilitated employees’ PEBs at work. More importantly, in real organizational settings, employees are likely to engage in PEBs even when receiving only supportive information from the organization. Our findings highlight the role of organizations in shaping eco-friendly employees from the perspective of organizational support. Practical implications for organizations to integrate environmental sustainability are also provided.

先前的研究已经充分证明了组织支持与工作中的环保行为（PEB）之间的正相关关系。然而，关于它们之间因果关系的证据有限。我们对于员工在工作中的 PEB 是否可以通过实际工作环境中的组织支持来激发也知之甚少。本研究探讨组织支持如何通过多种方法影响员工在工作中的 PEB。具体来说，进行了横断面调查（预研究，n  = 219）、回忆范式实验（研究 1，n  = 101）以及公司实地研究（研究 2）。三项子研究的结果一致表明，组织支持有效促进了员工在工作中的 PEB。更重要的是，在真实的组织环境中，即使只从组织收到支持性信息，员工也可能参与 PEB。我们的研究结果从组织支持的角度强调了组织在塑造环境友好型员工方面的作用。还提供了组织整合环境可持续性的实际意义。
