Question

which action is the best example of supply-chain sustainability?
moving production to the cheapest factory available
using faster shipping methods even if they pollute more
reducing pollution and improving working conditions across suppliers
selling a product in as many countries as possible

Explanation:

Supply - chain sustainability focuses on environmental and social responsibility along with economic aspects. Moving production to the cheapest factory may ignore social/environmental factors. Faster but more polluting shipping goes against environmental sustainability. Selling in many countries is about market reach, not sustainability. Reducing pollution (environmental) and improving working conditions (social) aligns with supply - chain sustainability.

Answer:

C. Reducing pollution and improving working conditions across suppliers
