Kirkland Signature Organic Creamy Peanut Butter

Scanned March 2026 · food · high confidence

This Kirkland Signature Organic Peanut Butter is a solid choice! The USDA Organic certification is a strong indicator of genuine effort in sustainable farming practices, which is fantastic for a food product where agriculture is the biggest impact. While Costco (the parent company) could be more specific about this particular product's full supply chain details, the organic label itself means they're doing a lot right where it counts.

How do the five signals break down?

Each signal is worth 20 points — the method is public at how we score.

What is on the label?

Primary claim: "USDA Organic" — a claim, not a certification. The difference is the whole game: see the cert guide.

What the claims cover

• USDA Organic certification means no synthetic pesticides or fertilizers, promoting soil health and biodiversity.
• The claim "100% U.S. Valencia Peanuts" is specific about the origin and type of peanuts, which is great for traceability.
• Organic farming practices directly address the biggest environmental impacts of peanut cultivation.
• The USDA Organic standard is a rigorous, action-based certification, not just a marketing term.

What is still missing

• Details about the plastic packaging (e.g., recycled content, recyclability instructions) are not visible, which is a common omission.
• Information on the carbon footprint of the product (from farm to shelf) is not provided, making it hard to understand its full climate impact.
• Specific labor practices beyond the general organic standards are not mentioned, which can be a factor in agricultural supply chains.
• Water usage in peanut cultivation isn't detailed, which is an important consideration for agriculture.

Where the footprint lives

Scope 1 — direct operations: Scope 1 covers the direct emissions from things the company owns or controls, like the fuel burned in their own factories or delivery trucks.

Scope 2 — purchased energy: Scope 2 is about the indirect emissions from the energy a company buys to power its operations, like electricity for the peanut butter processing plant.

Scope 3 — the supply chain: Scope 3 includes all the other indirect emissions that happen up and down the company's value chain, like the emissions from growing the peanuts, making the plastic jar, and transporting the finished product. This is usually where 70-90% of a food product's total impact hides, and it's rarely fully disclosed on the label.

Most of a product's emissions sit upstream in Scope 3 — the scope breakdown explains why that decides the score.

Smart swaps and tips

• Keep an eye out for packaging claims like 'made with recycled content' or 'easily recyclable' to round out the sustainability picture.
• If you're curious about the brand's broader efforts, check Costco's main sustainability report for company-wide goals.
• Consider reusing or repurposing the plastic jar once the peanut butter is finished to extend its life.
• Look for brands that also mention regenerative agriculture practices, which go a step further than organic in building soil health.
