The Difference Between Sustainable, Organic, and Regenerative Farming
These three terms get used interchangeably in farm marketing and food media, but they describe different things. Each has a different scope, a different level of legal or third-party oversight, and a different set of commitments from the farmer.
Sustainable Farming: The Broadest and Least Defined Term
"Sustainable" has no legal definition in the United States and is not regulated by any federal agency. Any farmer, food brand, or retailer can use the term without meeting any specific standard or undergoing any inspection.
In general usage, sustainable farming refers to practices that meet present needs without compromising the ability of future generations to meet theirs — a definition borrowed from the 1987 Brundtland Commission report on sustainable development. In agriculture, this broadly means:
- Not depleting the soil faster than it can recover
- Managing water responsibly
- Reducing or eliminating environmental harm from chemical inputs
- Maintaining viable farm economics that allow continued operation
Because there is no certification process, "sustainable" is best understood as a direction or philosophy rather than a verifiable standard. When a farm or brand calls itself sustainable, the most useful follow-up question is: sustainable by what specific practices and compared to what baseline?
Organic Farming: Federally Regulated With Specific Requirements
USDA Organic certification is a legal standard administered under the National Organic Program (NOP), established by the Organic Foods Production Act of 1990 and implemented through regulations first published in 2002 (7 CFR Part 205).
To use the USDA Organic seal, a farm or food product must be certified by an accredited certifying agent and meet specific requirements, including:
- No synthetic pesticides or fertilizers. Organic farmers use approved substances from the National List of Allowed and Prohibited Substances; synthetic pesticides and most synthetic fertilizers are prohibited.
- No GMOs. Genetically engineered seeds and organisms are excluded.
- No antibiotics or synthetic growth hormones in organic livestock.
- Organic feed for organic livestock. Certified organic animals must be fed certified organic feed.
- Pasture access for ruminants. Organic regulations require that certified organic cattle, sheep, goats, and other ruminants have pasture access for a minimum of 120 days per year and receive at least 30% of their dry matter intake from pasture during the grazing season.
Organic certification requires annual inspections by an accredited certifier and fees based on the operation's size. Small farms — particularly those selling under $5,000 per year in organic products — are exempt from certification requirements but cannot use the USDA Organic seal.
What organic does not guarantee:
- Soil improvement. Organic standards prohibit synthetic inputs but do not require that soil health measurably improve over time.
- Animal welfare beyond baseline minimums. The organic pasture rule is a minimum, not a welfare standard.
- Local or regional sourcing. An organic product can be certified organic and shipped from anywhere in the world.
- Carbon sequestration or positive climate impact.
Regenerative Farming: Higher Goals, Newer Standards
Regenerative agriculture has no federal legal definition as of early 2026. It is not regulated by any U.S. government agency, and there is no equivalent to the USDA NOP for regenerative claims.
However, several third-party certification programs have emerged to verify regenerative practices:
Regenerative Organic Certified (ROC) — Created in 2018 by the Regenerative Organic Alliance, whose founding members included the Rodale Institute, Dr. Bronner's, and Patagonia. ROC is built on a three-pillar framework:
- Soil health — practices that actively build soil organic matter, including cover cropping, composting, crop rotation, and minimizing tillage
- Animal welfare — standards that exceed organic requirements, including meaningful outdoor access and humane handling
- Social fairness — standards for fair wages and working conditions for farm workers
ROC uses USDA Organic certification as its baseline — a farm must already be certified organic to pursue ROC — and then adds the higher requirements on top.
Savory Institute Land to Market — A supply chain verification program for regenerative land management, based on the Ecological Outcome Verification (EOV) protocol. This program is specifically focused on grassland ecosystems and livestock operations, measuring actual ecological outcomes (soil health, biodiversity, water cycle function) rather than input restrictions.
Practical differences between organic and regenerative goals:
- Organic asks: "Are you avoiding harmful inputs?"
- Regenerative asks: "Are you actively improving the ecosystem?"
A well-managed regenerative farm is trying to increase soil organic matter each year, build biodiversity, sequester carbon, and enhance the water cycle on that land — not just avoid doing harm.
Side-by-Side Comparison
| Feature | Sustainable | USDA Organic | Regenerative Organic Certified |
|---|---|---|---|
| Federal legal standard | No | Yes (USDA NOP) | No |
| Third-party certification | No | Required for seal | Yes (ROC) |
| Prohibits synthetic pesticides | Not required | Yes | Yes (organic baseline required) |
| Requires soil improvement | Not required | Not explicitly | Yes |
| Animal welfare standards | Not required | Basic (120-day pasture) | High (exceeds organic) |
| Social fairness standards | Not required | No | Yes |
| Applies globally | N/A | Yes | Yes |
Certified Naturally Grown: An Alternative for Small Farms
Certified Naturally Grown (CNG) is a peer-review certification program designed for small-scale farms that follow organic practices but find USDA Organic certification prohibitively expensive or paperwork-intensive. CNG farmers follow the same core NOP practices, verified by other farmers rather than paid certifiers. CNG is not legally equivalent to USDA Organic but is widely respected in direct-market and farmers market settings.
What This Means for Buyers
When you see these labels on products, here is a useful interpretive guide:
- "Sustainable" — Ask what they mean specifically. Without certification, it is marketing language.
- USDA Organic — A real, audited standard with meaningful requirements. A solid baseline.
- Regenerative Organic Certified — A higher bar than organic, with third-party verification of soil, animal welfare, and worker fairness improvements.
- Certified Naturally Grown — Organic practices verified by peers; common on small direct-market farms.
All four are better than no standard at all. The most direct way to understand a farm's actual practices remains asking the farmer, which is one of the enduring advantages of buying local.
