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

To join the Product Use pillar of Project Gigaton, your company should commit to improve the in-use energy efficiency of your product(s). By making the products our customers know and love more energy efficient, we can help our customers lower greenhouse gas emissions. 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 products sold 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. The best goals are specific, measurable, and time bound. 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 and how will it be converted to GHGs?

Each year, you’ll be asked to submit data points to Walmart based on the Project Gigaton pillars you’ve joined (Energy, Waste, Agriculture, etc.). For Product Use, you’ll be asked to submit the impact of improvements you’ve achieved in a given reporting year. There are two options for submitting Product Use data to Project Gigaton reporting:

Option 1: If your company already reports to the CDP Climate Change Questionnaire each year, this information can be leveraged to report emissions reductions to Project Gigaton. To report to Project Gigaton using your CDP disclosure, you must grant permission for Walmart to use your CDP disclosure during the sign up or reporting process and the following CC3.3b fields must be completed in your CDP disclosure:

  • Activity type
  • Description of activity
  • Estimated annual metric tons CO2e savings
  • Scope

Please use the 2017 CDP Climate Change Reporting Guidance to properly respond to question CC3.3b.

Option 2: For companies that do not report their emissions reductions to the CDP Climate Change Questionnaire each year, or who have implemented projects but are unable to calculate the greenhouse gas impacts, you can still report to Project Gigaton by submitting the following data points and Walmart will calculate the emissions reductions:

Energy consumed per hour of use (baseline product and more efficient product)
Electricity (kWh)/hour of use
Gasoline (gallons)/hour of use
Natural gas (MCF or therms)/hour use
Lifetime hours of use (baseline product)
Number of units sold in reporting year (more efficient product)

The supplier chooses the “baseline product”, which must be the supplier’s own product that represents the generation immediately preceding the more efficient product. If no such prior product exists, the supplier should choose the baseline based on guidance found in the Project Gigaton Accounting Policy.

There is no need to report every action – similar initiatives can be grouped together and recorded on a programmatic level (e.g. developing average figures that are weighted proportionately to the products represented).

Once data has been submitted, the greenhouse gas equivalency will be calculated using the approach outlined in Walmart’s Project Gigaton Accounting Policy.
