Walmart de Mexico SAB de CV, also known as Walmex, is a subsidiary of the American retail giant Walmart Inc. The company is headquartered in Mexico City and operates in the Mass Merchants sector, with a focus on retail sales of groceries, clothing, electronics, and other consumer goods. Walmex is one of the largest retailers in Mexico, with over 2,500 stores and more than 300,000 employees across the country.

In recent years, Walmex has been making significant efforts to reduce its carbon footprint and transition to renewable energy sources. The company has set ambitious targets for decarbonisation and has implemented a range of initiatives to achieve these goals.

One of the key areas of focus for Walmex has been corporate energy management. The company has invested heavily in energy efficiency measures, such as LED lighting, HVAC upgrades, and smart building systems, to reduce its overall energy consumption. In addition, Walmex has implemented a range of renewable energy projects, including solar panels, wind turbines, and biomass boilers, to generate clean energy on-site.

To further support its renewable energy goals, Walmex has also entered into several corporate power purchase agreements (PPAs). These agreements allow the company to purchase renewable energy directly from a third-party provider, typically a wind or solar farm, at a fixed price over a long-term contract. By doing so, Walmex is able to secure a stable and predictable source of renewable energy, while also supporting the development of new renewable energy projects.

One notable example of Walmex's corporate PPA initiatives is its partnership with Enel Green Power Mexico. In 2019, Walmex signed a 10-year agreement to purchase 33% of the energy generated by Enel's new 220 MW wind farm in Coahuila, Mexico. The project is expected to generate over 800 GWh of clean energy per year, equivalent to the electricity consumption of around 500,000 Mexican households.

Walmex has also been working to reduce its carbon footprint through a range of other initiatives. For example, the company has implemented a waste reduction program, which includes recycling, composting, and waste-to-energy conversion. In addition, Walmex has introduced eco-friendly packaging and has set targets to reduce its greenhouse gas emissions from transportation and logistics.

Overall, Walmex's efforts to decarbonise and transition to renewable energy sources are commendable. The company has set ambitious targets and has implemented a range of initiatives to achieve these goals. By investing in energy efficiency measures, renewable energy projects, and corporate PPAs, Walmex is not only reducing its carbon footprint but also supporting the development of a more sustainable energy system in Mexico.

However, there is still room for improvement. Walmex could consider setting even more ambitious targets for decarbonisation and renewable energy adoption, as well as exploring new technologies and approaches to further reduce its environmental impact. In addition, the company could work to engage its suppliers and customers in its sustainability efforts, to create a more holistic and impactful approach to sustainability.
