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 avoid one billion metric tons (a gigaton), of greenhouse gas emissions from the global value chain by 2030. There are innumerable ways to reduce or avoid emissions in your operations or supply 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 via 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, Forests, 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 supplier industries and products. Explore the other pages on this site for more information and practical guidance on setting an Energy, Waste, Packaging, Agriculture, Forests, 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, Walmart understands that business benefits can come from developing, setting, and pursuing a 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 many 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. Formal, specific goals lead to substantially better returns and are an important part of being eligible to be recognized by Walmart; so, when setting a new goal, make sure it’s SMART. SMART goals are:

  • Specific – what’s your impact area?
  • Measurable – can you measure progress?
  • Achievable – is this a reasonable goal?
  • Relevant – does this fit into your strategy?
  • Time limited – by when?

After joining Project Gigaton, you’ll be asked to report on your progress annually so the impact can be recognized and attributed toward the Project Gigaton 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 your own operations or your supply chain. It’s often easiest to start by focusing targets on either your own operations and build toward 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 many 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

Strategy
WWF
EDF

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 the reporting year. There are three options for submitting emissions data to Project Gigaton reporting:

Option 1: If your company already reports to the CDP Climate Change Questionnaire each year, your disclosure can be leveraged to report emissions reductions to Project Gigaton. To report to Project Gigaton using your CDP disclosure, you must grant permission through your company’s Project Gigaton account for Walmart to use your CDP data and the following CC4.3b fields must be completed in your CDP disclosure:

  • Activity type and description
  • Estimated annual metric tons CO2e savings
  • Scope
  • Estimated lifetime of the initiative
  • Percent of CO2e savings dedicated toward Project Gigaton (assumed to be 100% unless otherwise noted)

Please use the CDP Climate Change Reporting Guidance to properly respond to question CC4.3b. 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.

Option 2: For companies that do not report their emissions reductions to the CDP Climate Change Questionnaire each year, you can still report your already calculated aggregate greenhouse gas emissions reductions to Project Gigaton by providing the following:

  • Estimated annual metric tons CO2e savings
  • Activity type and description
  • Scope
  • Estimated lifetime of the initiative

Option 3: For companies that need help calculating the greenhouse gas impacts of their initiatives, you can still report to Project Gigaton by submitting the specific data points and allowing Walmart to calculate your greenhouse gas emissions reductions according to approach described in the 2018 Project Gigaton Accounting Methodology. You can submit data points for one or more of the six key pillars of Project Gigaton - Energy, Waste, Packaging, Agriculture, Forests, 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.
