The logistics and transport sector generates over a third of global CO2 emissions, significantly contributing to a company’s Scope 3 emissions. As regulatory targets become increasingly demanding, the selection of logistics service providers plays a crucial role for logistics buyers attempting to meet sustainability goals. In response, logistics service providers have been implementing a variety of green logistics practices to reduce their impact on the natural environment. The research aims to determine the most important green logistics practices influencing logistics buyers’ decisions in the context of logistics service providers’ selection. Grounded in behavioral decision theory, we test our hypotheses by conducting a series of scenario-based experiments with logistics and supply chain managers as respondents. The findings of this research aim at providing timely and practical guidance for managers at logistics service provider firms seeking to align their sustainability initiatives with buyer expectations.
