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 all over the world.
By implementing best practices in manure management, enteric emissions, feed inputs, and other activities in animal agriculture, along with fertilizer optimization in crop production, we estimate there is a potential to reduce 300 million metric tons (MMT) of GHG emissions by 2030. With almost 92 million cattle, 71 million swine and millions of acres of farmland in the U.S. alone, there’s an important opportunity to scale solutions in agriculture.
Get involved by having your company commit to reducing emissions at the farm level.
For example, you could commit to:
- Optimize fertilizer use in corn production using optical sensors showing nutrient use efficiency improvement of more than 20% across 1,000 acres by 2025.
- Expand Sustainable Farming Initiative (SFI) across 4 million acres to increase environmentally responsible agricultural practices, improve crop yields and growers’ livelihoods.
- Implement animal agriculture best practices to reduce enteric and manure emissions across 2 million acres by 2030.
The above goals are illustrative examples only. You’ll need to determine the scope, timeline and type of goal that makes sense for your company and products. 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.

The adoption of best-in-class agricultural practices can help lower greenhouse gas emissions. One of the best ways to do this for row crops is to set a fertilizer optimization commitment. 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 and practices - from the most basic to the most advanced - that you can build and implement in your supply chain.Fertilizer Efficiency programs and practices grouped by expected GHG savings
Low GHG Medium GHG High GHG • Data collection tool that helps benchmark current practices
• Rate recommendation based on model optimizing fertilizer cost and crop yield
• Land-grant university rate recommendation
• Reduced tillage including conservation tillage and no-till
• Non-nitrogen fixing cover crops
• Combination of tools or farmer surveys with sufficient data showing nutrient use efficiency improvement of less than 10%
• Precision agriculture calibrated to optimize yield
• Mid- to late-season application informed by nitrogen-loss monitoring using real-time weather data
• Optical sensors with nutrient use efficiency improvement lower than 20% or unknown
• Nutrient/Soil management based on soil mapping
• High efficiency/sub-surface drip fertigation
• Crop rotation or cover crop with nitrogen fixing crops such as soy, alfalfa, legumes, etc.
• Working with an agronomist to evaluate and improve nutrient use efficiency
• Combination of tools, programs, or farmer surveys with sufficient data showing nutrient use efficiency improvement of 10-20%
• Overall rate recommendations optimized using real-time weather data
• Use of a nitrification inhibitor
• Optical sensors showing nutrient use efficiency improvement of more than 20%
• Combination of tools, programs, or farmer surveys with sufficient data showing nutrient use efficiency improvements of more than 20%

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:

- How to calculate and report emissions saved.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 every pillar you report to, you’ll be asked to submit the impact of improvements you’ve achieved in the reporting year. There are three options for submitting data to Project Gigaton reporting:
Option 1: For companies that need help calculating the greenhouse gas impact of their initiatives, let the Project Gigaton Calculators help! These calculators are available to help you report your progress during the annual Project Gigaton reporting period. They may also help you identify and estimate the emissions impact of future Project Gigaton goals.
Option 2: 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 all CC4.3b fields must be completed in your CDP disclosure. If you haven’t received a request to disclose from CDP but would like to volunteer to do so, or have questions about disclosure, please contact firstname.lastname@example.org.
Option 3: For companies that do not use the Project Gigaton Calculators or 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.
