When we think about greenhouse gas (GHG) emissions in the value chain, the focus is often manufacturing and how we can manufacture products in a more sustainable way. But what about once a product leaves the shelf and goes home with our customer?

Consumer use is an important part of a product’s lifecycle. Designers, manufacturers and brands have a unique opportunity to help customers be more sustainable by delivering more efficient and innovative products to shelf – specifically, products that help the customer lower the greenhouse gas emissions associated with their enjoyment of a product.

How to Join


By making the products our customers know and love more energy efficient, we can help our customers lower greenhouse gas emissions.

To join the Product pillar of Project Gigaton, your company should set a goal to improve the in-use energy efficiency of your product(s). This results in the reduction of GHG emissions at the customer level.

For example, you could submit a goal to:

  • Increase your product(s) energy efficiency by 20 percent by the year 2021.
  • Help customers avoid 1 billion kWh of energy use between now and 2025.
  • Decrease GHGs emitted through product use by 25 percent by 2030.
  • Increase the energy efficiency of half our products by 2020.

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 one gigaton reduction target.

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 energy efficiency improvements you’ve achieved in your product(s). For product use goals, you'll be asked to submit:

1. Energy use of the baseline product, which should be calculated as follows:

Please note, the “baseline product” must be the product generation immediately preceding the “more efficient” product.

2. Energy use of the more efficient product

Please note, the “more efficient” product can only contribute emissions reductions to Project Gigaton for five years following its retail date, after which we will consider it business as usual for purposes of Project Gigaton.

3. Type of energy consumed, which should be specified as follows:

  • Electricity (kWh), gasoline (gallons), natural gas (MCF or therms)

4. Number of units sold for the reporting year

How will your reported information be converted to greenhouse gases?

Once the energy use gap between the baseline product and the more efficient product is determined, the greenhouse gas equivalency will be calculated using the EPA’s Greenhouse Gas Equivalencies calculator:

Once the per product greenhouse gas savings are calculated using the above methods, this figure will be multiplied by the number of product units sold during the reporting year. The total will be contributed toward the Project Gigaton reduction target.

By offering more energy-efficient products, companies can help customers lower the greenhouse gas emissions associated with enjoying those products. There are other product innovations that can provide emissions reduction benefits for the customer, including circular-design products or programs that help customers divert products from landfills toward reuse, refurbishment or recycling. Because much of this work is cutting edge, methods used to calculate the emissions impact of such innovations may need to be developed. If you believe you have an emissions-reducing product or service that should be counted toward Project Gigaton but isn’t covered by the energy-efficient products methodology, please tell us about it by contacting corpsu@wal-mart.com.
