Which of the following is one of the four areas of sustainability?

• A. Supply chain
• B. Marketing
• C. Finance
• D. R&D

Answer: (A)

Sustainability in business is understood as happening across the entire value chain, not just inside one department. The supply chain dimension matters because how materials are sourced, produced, transported, and handled by suppliers directly affects environmental impact, labor practices, and long-term economic viability. By improving ethical sourcing, reducing emissions in logistics, and ensuring responsible waste and end-of-life management throughout the chain, a company strengthens its overall sustainability performance. That’s why supply chain is listed as one of the four fundamental areas, alongside environmental, social, and economic (or governance) considerations. Marketing, finance, and R&D are important to business success, but they aren’t typically treated as the four sustainability areas themselves.
