Abstract
Background: Fundamental changes in the global economy have resulted in complex supply
chains that require continuous strategic adjustment in order to remain relevant, competitive and
sustainable. Increased use of road freight transport has resulted in an increase in global
greenhouse gas (GHG) emissions and impacts climate change.
Purpose: This study sought to explore the implementation of sustainable supply chain practices
aimed to reduce GHG emissions in the South African road freight industry.
Method: Empirical data were collected from a convenience sample of 108 supply management
profesionals employed at 13 logistics operating firms based in South Africa.
Findings: The results indicate that firms are placed under immense pressure to implement
sustainable practices. The main drivers for adopting sustainable initiatives are pressure from
consumer and brand protection; pressure from top management; and cost saving and revenue. The most
implemented initiative identified is eco-driving, eco-routing (routing and scheduling) and
increasing vehicle carrying capacity. The main benefits derived from implementing sustainable
supply chain initiatives were operational cost savings; increased competitive advantage; and
improved supplier relationships. However, the main challenges associated with implementing these
initiatives were lack of government support; lack of
understanding of the cost; and insufficient manpower...
