Agricultural practices have economic and environmental impacts for farmers, ranchers and buyers of their products.

The adoption of best-in-class agricultural practices, including precision agriculture and feed optimization, can help reduce farmer input costs, improve water quality and reduce greenhouse gas (GHG) emissions. With almost 92 million cattle, 71 million swine and millions of acres of farmland in the U.S. alone, there is an important opportunity to scale solutions in agriculture.

By pursuing best practices in areas such as manure management, enteric emissions and feed inputs in animal agriculture, we estimate there is a potential to reduce 300 million metric tons (MMT) of GHG emissions by 2030; while at the same time reducing waste and improving yield. In addition, we believe that through supporting fertilizer optimization and sharing best management practices with farmers in our agriculture supply chain, we estimate that there is a potential to reduce 25 MMT of GHG emissions by 2025.


How to Join

We are working with many of our suppliers to support efforts to optimize fertilizer use on a targeted 76 million acres of land by 2025. In addition, we are working with stakeholders across the beef, dairy, pork and poultry industries to adopt best practices that reduce enteric and manure emissions, optimize feed production and improve soil health. We hope you will join us in committing to reduce GHG emissions from agriculture.

To join the Agriculture pillar of Project Gigaton, your company should set a goal to reduce emissions at the farm level.

For example, you could submit a goal to:

- Kellogg Company: By 2025, support 500,000 farmers, focusing on Climate Smart Agriculture to improve livelihoods. Continue to help agricultural suppliers, millers and farmers to:

  • Adapt and be resilient to climate change.
  • Optimize use of fertilizer inputs.
  • Estimate GHG emissions and measure continuous improvement.
  • Optimize water use and enhance watershed quality.
  • Improve soil health.

- PepsiCo: 2025 Goal - Work to expand Sustainable Farming Initiative (SFI) across approximately seven million acres to increase environmentally responsible agricultural practices, improve crop yields and growers’ livelihoods, and advance respect for workers’ fundamental human rights. The expanded SFI includes action in crops that collectively represent approximately 75 percent of PepsiCo’s current agricultural-based spend.

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 for setting a fertilizer target

Establishing a fertilizer commitment will be unique for each company. Your goal may be to improve nutrient management through benchmarking or to work with a highly trained professional on practical ways to fine tune your application processes. Below are examples of the types of programs - from the most basic to the most advanced - that you can build in your supply chain.

What will you report each year?

Each year, you’ll be asked to submit data points to Walmart. This information will be used to calculate the greenhouse gas impact of the improvements you’ve achieved in your product(s) from working to optimize fertilizer use. For fertilizer goals, you'll be asked to submit:

  • Number of acres engaged in fertilizer optimization program
  • Location of crops engaged in fertilizer optimization program
  • Crop types engaged in fertilizer optimization program (e.g. corn, wheat, soy)
  • Tools and/or programs used to optimize fertilizer use for specific crops and locations. Types of programs should be based on the following program guidance (out of 4). Suppliers should strive for Level 4 programs.
How will your reported information be converted to greenhouse gases?

Once data has been submitted, the greenhouse gas equivalency will be calculated using the formula below. Emissions factors will be shared later this year.

Animal Agriculture

Practical guidance for setting an animal agriculture goal

When it comes to setting an animal agriculture goal, there are many approaches to achieve emissions reductions and the solution is dependent on the type of animal. You may find the below templates helpful in setting an animal agriculture goal:

What will you report each year?

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

  • Number of animals
  • Type of animals (beef, dairy, pork or poultry)
  • Types of programs
How will your reported information be converted to greenhouse gases?

The estimated greenhouse gas emissions reduced based on your outlined commitment will be calculated using government (e.g., USDA, US EPA), industry and literature values using informed assumptions about typical practices.

For example, each dairy farm anaerobic digester will be assumed to have methane reductions reported by the U.S. EPA for the amount of methane from manure reported by the industry. If your program has unique considerations (e.g., your average herd size is larger than an expected average), please tell us by contacting

Calculations for animal agriculture are currently in development and will be shared later this year.

While we have tried to present a menu of potential options for reducing agricultural emissions, we realize that our list is not exhaustive. Additionally, since much of this work is cutting-edge, methodologies to calculate the emissions impact of such innovations may need to be developed. If you believe you have an emissions-reducing practice or technology that should be counted toward Project Gigaton, but it is not covered here, please tell us about it by contacting
