External institutional pressures are pressures from outside the organization and include factors such as national and local government initiatives for promoting the development of a low-carbon society, transportation and logistics industry associations, the public’s normative expectations, supply chain members and peer competition imitation.
Mandatory pressure includes initiatives from all levels of government. These agencies are authorized to promulgate and implement regulations concerning green logistics. All kinds of planning and incentive measures for promoting the development of green logistics will directly affect the majority of truck fleets’ environmental behavior.
