OilCom's pathway to sustainability integration, as shown in Fig. 2, commenced from the dormant decoupled strategy, moved to a compliance-driven sustainability strategy and then a peripheral sustainability integration configuration. Currently, it is moving to- wards an integrated sustainability strategy. During its early years, OilCom did not have a sustainability strategy. The MCSs were still being developed and sustainability was managed in response to growing pressures for increased health and safety performance in the industry (in Fig. 2, moving from A to C). As OilCom employees gained a broader and deeper knowledge of sustainability issues, integration of the MCSs and SCSs occurred, which underpinned greater technical and organ isational sustainability integration (from c to G). Even though oilCom could currently be described as resembling configuration G, it is heading towards the mobilisation of the SCSs, which may eventually lead to full sustainability integration within its corporate strategy (configuration H). The Gond et al. (2012) model suggests that the integrated sus tainability strategy emerges through the subtle incorporation of the scss in organisational systems. In Fig. 2, the first two configurations depict low levels of integration (characterized by a loose coupling between MCSs and SCSs), while the last two configurations occur with higher levels of integration (tight coupling of MCSs and SCSs). oilcom's MCSs and s could currently be described as loosely
