Walmart’s Project Gigaton: A Guide for Suppliers

Author: Jarrod Davis

In every new initiative Walmart develops, one goal remains at the core: commitment to the customer. That commitment goes far beyond low prices and customer service. It’s a promise reaching as local as the community, but as big as the world.

Walmart renewed its focus on the environment for its latest initiative. The company sees its responsibility to lead the way in preserving natural resources for future generations. In an effort to partner with suppliers in improving processes to protect the earth, Walmart launched Project Gigaton.

What Is Project Gigaton?

To explain the origin and goal of this initiative, Laura Phillips, SVP of Walmart Sustainability, was a guest on Focus on Suppliers.  She explained that earlier this year at Walmart’s Sustainability Milestone Meeting, Project Gigaton was announced as a plan to reduce environmental impact through Walmart’s supply chain.

“Walmart is committed to reducing emissions within our own operations as well as with our suppliers throughout the entire value chain,” Phillips said. “The challenge we’ve signed up for with our suppliers is to take out a billion metric tons of emissions. That’s a gigaton. Our challenge together that we launched at the Milestone Meeting is to work with our suppliers across different areas of work to take out a gigaton of emissions by the year 2030.”

Partnering with Suppliers

As a supplier, partnering with Walmart on Project Gigaton is not as cumbersome as it sounds. No matter what area of retail you work, there are many ways to reduce emissions within your own scope of influence. Phillips says there are different ways suppliers can participate in Project Gigaton. Many suppliers took action early and made amazing new commitments to the environment.

“We’ve had many suppliers make new commitments about areas of work they’re going to do toward the gigaton of reduction,” she explains. “Things like food waste, packaging, sustainable agriculture, fertilizer, and animal agriculture. We’ve even renewed commitments in areas like efficient energy products.”

Online Support for Suppliers

Walmart is not just encouraging suppliers to get involved. The company wants to help the project gigatonsupplier community by giving it the necessary tools to execute Project Gigaton across multiple areas of supply chain. That’s why they’ve launched the Walmart Sustainability Hub, a new supplier engagement platform online.

“We’ve designed new toolkits for suppliers,” Phillips says. “Whether they’re already leaders in the initiative or just getting started, suppliers can work in different areas in Project Gigaton. They simply sign up alongside Walmart to do the work together in the supply chain.”

One quick click to the Walmart Sustainability Hub gives a supplier tangible goals to reduce emissions. For example, in the areas of Packaging, Walmart lays out ideas of:

  • Switching from corrugate containers to reusable packaging containers
  • Designing for recyclability
  • Decreasing packing weight
  • Switching from glass to plastic

The Walmart Sustainability Hub provides the supplier with an array of ideas, goals, and reporting tools to partner with Walmart on the emissions reduction process.

Measuring Progress and Success

Project Gigaton is a large initiative, but with a large payoff for the environment. Phillips concluded her visit by touching on accountability. Using the online resources will not only support suppliers, but show how they and Walmart are achieving the goal.

“We’ll use the Walmart Sustainability Hub to share information and commitments,” she explains. “We’re also launching a metrics and measurements program very similar to the Sustainability Index that suppliers use today. We’ll be working together to monitor our progress over the next several years.

“All of these activities together, when we do them well, will add up to a gigaton of emissions reduction. It’s great for the environment, it’s great for our customers, and it saves money in our business.”
