What principle does Uniqlo uphold by donating proceeds from paper bags?

Uniqlo demonstrates its commitment to corporate social responsibility by donating proceeds from paper bags. This practice aligns with the principle of giving back to the community and supporting social initiatives, showcasing the company's dedication to making a positive impact beyond just profits. Corporate social responsibility emphasizes ethical practices, environmental stewardship, and community engagement, which are fundamental to building a sustainable business model. By integrating this principle, Uniqlo not only enhances its brand reputation but also connects with customers who value companies that contribute to social causes.

The other options, while important business strategies, do not accurately describe the motivation behind donating proceeds from paper bags. Cost reduction focuses primarily on minimizing expenses, market expansion pertains to increasing the company's reach and growth in new markets, and brand loyalty building centers on fostering customer commitment and repeat business. None of these accurately reflects the altruistic initiative of donating from sales, which is rooted in corporate social responsibility.
