Reducing greenhouse gas (GHG) emissions, which fuel climate change, can seem daunting – but it doesn’t have to be. There are time-tested and cost-effective enterprise strategies that are designed to help address this challenge. So what’s stopping your company from taking the next step and setting a target?

Project Gigaton is an initiative to prevent one billion metric tons, or one Gigaton, of greenhouse gas emissions from global value chains by 2030. There are innumerable ways to reduce emissions in your operations or value chain and Project Gigaton is designed so that every supplier can participate no matter what type of product you sell. The first step is setting a goal and you can do this one of two ways:

  1. For suppliers just getting started on their emissions reduction journey, setting a target in one or more of six key areas - Energy, Waste, Packaging, Agriculture, Deforestation, or Product Use - might be the right place to start. Each of these program pillars was chosen because of the meaningful and practical opportunities to prevent greenhouse gas emissions across many different suppliers and products. Explore the other pages on this site for more information and practical guidance on setting an Energy, Waste, Packaging, Agriculture, Deforestation, or Product Use target.
  2. For companies that have worked on sustainability for some time, or for those ready to progress towards a broad emissions reduction strategy, setting an emissions reduction target that captures your work across many areas might be the right next step. Keep reading this page for more information and practical guidance on setting a broad emissions reduction target.

From our own experience, we understand that business benefits can come from developing, setting, and pursuing a GHG reduction target. According to a joint report published by the World Wildlife Fund (WWF) and CDP (formerly Carbon Disclosure Project), U.S. businesses that commit to annually cutting their greenhouse gas (GHG) emissions can collectively reap as much as $190 billion in annual savings from reduced energy bills, increased productivity, and other associated benefits. Similar opportunity exists around the world.

Resources

Individual businesses can get started by viewing emissions as another form of waste, with financial value, or as a symptom of inefficiency in the value chain. The focus then becomes working toward a reduction in emissions leading to increased ROI, profit, and value.

Walmart believes in the value of setting such ambitious emission reduction goals, which is why we announced a science based target to cut our operational emissions 18 percent by 2025 in addition to Project Gigaton. Walmart’s emission reduction goal serves as an umbrella to cover a broad array of emissions reductions activities and sub-targets to reduce waste, improve efficiency, increase renewable energy use, and more.

How to Join


So, what type of emissions reduction goal should you set? While we encourage you to aim for an ambitious Science Based Target, your goal should reflect the maturity of your company’s sustainability program and can take a number of forms and timelines.

For example, you could set a goal to:

  • Cut carbon intensity per revenue in half by 2030.
  • Achieve a 20 percent absolute reduction in emissions by 2030.
  • Achieve a science based target by reducing absolute emissions 35 percent by 2030 and 80 percent by 2050.

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 reduction target.

Practical guidance on developing a program and setting an emissions target

Every company is in a different stage of the emissions reduction journey, and companies can set a target focused on you operations or value chain. It’s often easiest to start by focusing targets on your own operations and build towards a value chain goal. Your “own operations” includes Scope 1 and Scope 2 emissions (see figure below). Scope 3 includes your “value chain”.

  • Scope 1 emissions are direct emissions from sources that are owned or controlled by your company such as factories, office buildings, and company-owned fleet vehicles.
  • Scope 2 emissions are indirect emissions resulting from the generation of purchased energy, primarily electricity.
  • Scope 3 emissions are indirect emissions resulting from upstream activities such as production of goods and services purchased by the company, as well as downstream activities such as consumer use and disposal of products sold by the company.

Strategy frameworks such as the Carbon Productivity Portfolio can be useful when developing your company’s emissions reduction plans and goals. Organizations like Climate Corps Graduate Fellowship Program and many consulting firms offer professional and technical services to help you develop goals and expand your program.

Tools such as the Carbon Target and Profit Calculator can also be used to quickly estimate the potential value of goals for your company. Reviewing case studies can provide additional insights into how other companies think about goal setting and their implementation plans.

While your goal should reflect the maturity of your company’s sustainability program and can take a number of forms and timelines, we encourage you to aim for an ambitious Science Based Target.

Targets adopted by companies to reduce greenhouse gas (GHG) emissions are considered “science-based” if they are in line with the level of decarbonization required to keep global temperature increase below 2 degrees Celsius compared to pre- industrial temperatures, as described in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5).

When it comes to setting Science Based Targets (SBT) there are several methods available to you. The method a company chooses to use depends on its particular circumstances. Find out more about the different methods here or even go straight to the complete SBT manual to begin setting your own SBT.

Several organizations work with businesses in their efforts to build or improve emission reduction strategies. Some of these organizations include:

Climate Disclosure
WRI GHG Protocol Corporate Standard
CDP
EPA Center for Corporate Climate Leadership

What will you report each year?

Each year, you’ll be asked to submit data points to Walmart for the Project Gigaton targets you’ve set. For emissions targets, you’ll be asked to submit the impact of improvements you’ve achieved in a given reporting year. There are two options for submitting emissions 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
  • Estimated lifetime of the initiative (if applicable)

If you haven’t received a request to disclose from CDP but would like to volunteer to do so, please contact walmart@cdp-sc.com and CDP will help you get started. 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, but are able calculate the greenhouse gas impacts of their work, you can still report to Project Gigaton by submitting the following data points:

  • Activity type
  • Description of activity
  • Estimated annual metric tons CO2e savings
  • Scope
  • Estimated lifetime of the initiative (if applicable)

Option 3: 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 data points for one or more of the six key areas of Project Gigaton - Energy, Waste, Packaging, Agriculture, Deforestation, or Product Use - and Walmart will calculate the emissions reductions.

Reducing emissions in your business is a journey. Whether you are just starting out or have many years of experience, we hope you will join us as we work toward a better tomorrow. If you are not ready to set an emissions goal for your operations or supply chain, please consider making a commitment with one or more of the six areas of Project Gigaton listed below.
