Kroger is one of the largest retail companies in the United States, operating a variety of supermarket chains and multi-department stores. With a history dating back to 1883, Kroger has established itself as a significant player in the grocery industry, offering a wide range of products including fresh produce, meat, dairy, and household essentials.

In terms of sustainability, Kroger has made several commitments to reduce its environmental impact. The company has set goals to achieve zero waste by 2025 and to reduce its carbon footprint significantly. Kroger is actively working on improving energy efficiency across its stores and distribution centers, and it has invested in renewable energy projects.

Kroger's sustainability efforts also include initiatives to reduce food waste and promote sustainable sourcing. The company has partnered with various organizations to donate surplus food and has implemented programs to ensure responsible sourcing of seafood and other products. Kroger is a member of the Sustainable Seafood Coalition and has committed to sourcing 100% sustainable seafood by 2020.

Despite these efforts, Kroger has faced criticism for not being transparent enough in its sustainability reporting. The company has been urged to provide more detailed information on its progress towards its environmental goals. However, Kroger continues to work towards enhancing its sustainability practices and reporting.
