Global supply chains represent the backbone of modern economic activity, linking producers, suppliers, and consumers across continents. These complex networks enable efficiency and innovation but also raise significant sustainability challenges related to resource use, labor conditions, and environmental impact. The integration of sustainable policy design into global supply chains is therefore crucial for achieving long-term economic and ecological balance. As nations and corporations navigate global markets, policy frameworks that promote ethical sourcing, low-carbon logistics, and circular production systems become key instruments in shaping a sustainable future.

Understanding Global Supply Chains
A global supply chain refers to the network of production, distribution, and delivery systems that span multiple countries.
It includes raw material extraction, manufacturing, transport, warehousing, and retail.
Technological advances in communication and logistics have enabled global interdependence among businesses.
Sustainability in supply chains now extends beyond environmental responsibility to include social equity and governance transparency.
