Packaging plays an important role in protecting and delivering quality products to our customers. How can we best design a package to reduce associated greenhouse gas (GHG) emissions?

In most cases, packaging is simply a means to transport a product. Once the end user has removed the product packaging it becomes waste. By optimizing design, sourcing sustainably and supporting recycling in packaging, the reduction of greenhouse gas emissions will be achieved through reduced weight in transportation and waste. Designers, manufacturers and brands have a unique opportunity to help deliver more efficient and innovative packaging to shelf.

How to Join


Making the packaging that your customer knows and loves more recyclable is a clear way to lower emissions. To join the Packaging pillar of Project Gigaton, your company can choose to set a goal specific to any or all of these areas: 1) optimize design, 2) source sustainably or 3) support recycling.

For example, you could submit a goal to:

  • Design for recyclability for 50 percent of packaging by 2025.
  • Lessen the weight of your packaging by 10 percent by 2020.
  • Switch from glass to plastic for packaging by 2021.
  • Increase use of recycled content or bio-based materials by 15 percent by 2030.
  • Switch from corrugate containers to reusable packaging containers (RPCs) to reduce damages by 20 percent by 2019.

The above goals are illustrative examples only and by no means the only goal style that could be submitted as part of Project Gigaton – you’ll need to determine the scope, timeline and type of goal that makes sense for your company and products. After submitting a goal using the button below, you’ll be asked to report on your progress annually so the impact can be recognized and attributed toward the Project Gigaton reduction target.

Practical guidance on setting a packaging target

Please consider Walmart’s sustainable packaging priority areas when looking to set a packaging goal. Walmart’s packaging playbook provides best practices, additional guidance and resources.

What will you report each year?

Each year, you’ll be asked to submit data points to Walmart based on the specific goal you submit. This information will be used to calculate the greenhouse gas impact of the packaging improvements you’ve achieved. For packaging goals, you'll be asked to submit:

  • Sales volume of packaging
  • Weight of old and new packaging
  • Material type of old and new packaging
  • % change in sustainably sourced content
  • % change in damages

To avoid double counting, your company can select either a recyclable or recycled content goal to count towards Project Gigaton. In general, we encourage companies to work on both increasing the recyclable and recycled content in packaging.

What tools are available to evaluate sustainable packaging changes?

Optimizing Design and Sourcing Sustainably

  • Consider using the COMPASS (Comparative Packaging Assessment) tool.
  • If you believe you have an alternative methodology that should be used to measure progress toward Project Gigaton, but isn’t covered by the COMPASS tool, please tell us about it by contacting corpsu@wal-mart.com.

Supporting Recycling

  • Consider using the How2Recycle labeling system.
  • If you believe you have an alternative methodology that should be used to measure progress toward Project Gigaton, but isn’t covered by the COMPASS tool, please tell us about it by contacting corpsu@wal-mart.com.
How will what you report be converted to greenhouse gases?

Calculations for optimizing design and sourcing sustainably are currently in development and will be shared later this year.
