Dollar Tree Inc., a U.S. Fortune 500 company in the deep discount retail industry faced pressure from the shareholder advocacy group As You Sow asking the company to intensify its climate transition plans and adopt a "net-zero" emission goal. The activist shareholder had filed a shareholder resolution to press the company and to engage other shareholders in its advocacy. This was not the company's first brush with climate-related shareholder pressure. In fact, a similar 2020 resolution that received record-breaking support already caused the company to revamp its sustainability initiatives. The case provides a brief overview of Dollar Tree's business, the recent landscape of sustainability reporting in the U.S., the nature of the environmental resolutions filed, and the narrative of management opposition to the resolutions. The case captures the interactions between environmental shareholder activism and those charged with governance and management. This case is useful for students who are interested in learning about recent trends of ESG-related shareholder activism and sustainability reporting, especially those related to environmental issues, and how companies may react to them.
