How Sustainable Is Petaluma Dog Food? The Carbon, Water, and Land Data
If the 163 million dogs and cats in the United States formed their own country, their meat consumption alone would rank among the world's largest sources of food-related emissions. One peer-reviewed analysis found that pet food is responsible for roughly a quarter to a third of the environmental impact of all animal-product consumption in the U.S. So when pet parents ask what the most sustainable dog food is, it is a serious question with measurable answers. This article shares Petaluma's third-party life cycle data, in plain numbers, so you can see exactly how a plant-based bowl compares to conventional kibble on greenhouse gas, water, and land.
Quick Answer
The most sustainable dog food is one with a measured, transparent environmental footprint, not just a green label. According to Petaluma's third-party life cycle assessments, feeding a dog our plant-based food instead of conventional meat-based kibble lowers diet-related greenhouse gas emissions by around 84%, freshwater use by around 65%, and land use by around 89%, without giving up complete, AAFCO-balanced nutrition.

Why your dog's food has an environmental footprint
Most of a dog food's environmental impact comes from one place: the ingredients, and especially the animal protein. Growing, raising, and processing those ingredients uses land, water, and energy, and livestock in particular releases methane and nitrous oxide, two potent greenhouse gases.
The scale is real. UCLA researcher Gregory Okin estimated that dog and cat food in the U.S. accounts for the equivalent of up to 64 million tons of carbon dioxide per year in methane and nitrous oxide alone, a figure published in PLOS ONE. A separate global analysis in Global Environmental Change put dry pet food at 56 to 151 million tons of CO2-equivalent emissions and 41 to 58 million hectares of agricultural land each year.
That is the context behind the search for eco-friendly dog food. The good news is that the same lever that drives the footprint up, animal protein, is the one a thoughtfully formulated plant-based recipe can pull down.
How we measure it: the life cycle assessment
A life cycle assessment, or LCA, is the standard scientific method for measuring a product's environmental footprint. It adds up the inputs and emissions across a product's whole life: growing the ingredients, processing them, packaging, and transport. The result is a set of concrete numbers rather than a vague claim.
At Petaluma, we commissioned third-party life cycle assessments for our recipes so the impact of our food is measured, not estimated. The full reports are public: you can read the adult formula LCA and the senior formula LCA in full. The numbers below come straight from those assessments, compared against conventional meat-based kibble.
Petaluma's environmental impact, by the numbers
Across our adult and senior recipes, switching a dog from conventional kibble to Petaluma reduces diet-related greenhouse gas emissions by around 84%, freshwater use by around 65%, and land use by around 89%.
Greenhouse gas emissions
~84% lower
Adult 83% · Senior 84%
Freshwater use
~65% less
Adult 62% · Senior 68%
Land use
~89% less
Adult 88% · Senior 89%
| Petaluma formula | Greenhouse gas reduction | Freshwater reduction | Land use reduction |
|---|---|---|---|
| Adult: Roasted Peanut Butter & Sweet Potato | 83% | 62% | 88% |
| Senior: Baked Pumpkin & Peanut Butter | 84% | 68% | 89% |
Figures are drawn from Petaluma's third-party life cycle assessments versus conventional meat-based kibble. For the full methodology and a deeper look at our practices, see our sustainability page.
Why plant-based lowers the footprint so sharply
The reductions are large because animal agriculture is resource-intensive in a way plant ingredients are not. Producing a calorie of protein from chickpeas, peanuts, or oats takes far less land and water, and emits far fewer greenhouse gases, than producing the same calorie from beef, chicken, or lamb.
Greenhouse gas
Livestock release methane and nitrous oxide directly, and clearing land for grazing or feed crops adds more. Removing factory-farmed animal products from the recipe removes the single largest source of those emissions. A 2025 review in Frontiers in Sustainable Food Systems found that nutritionally sound plant-based pet diets consistently carried a lower environmental burden than meat-based ones.
Water and land
Animal protein needs feed crops, and those feed crops need land and water, so the footprint compounds. Feeding plants to dogs directly skips that extra step. That efficiency is why our land-use reduction reaches nearly 89% and our freshwater reduction lands in the 62 to 68% range.
Sustainability without compromising nutrition
A lower footprint only matters if the food still nourishes your dog completely. At Petaluma, sustainability and nutrition are not a trade-off. Our recipes are formulated by veterinary nutritionists, use organic and whole-food ingredients, and are complete and balanced to AAFCO standards. The nutritional profile of each recipe is verified through third-party laboratory testing and published on the product page.
We evaluate each vitamin, mineral, and amino acid on its own merits, in the best interest of your dog's long-term wellness, rather than ruling out an ingredient category to follow a trend. For a closer look at whether dogs can flourish on this kind of diet, see our review of the research on the benefits of plant-based dog food.
A bowl that's better for your dog and the planet
Petaluma is plant-based, formulated by veterinary nutritionists, and complete and balanced to AAFCO standards, with a measured environmental footprint up to roughly 89% smaller than conventional kibble. See the difference in your own dog's bowl.
Beyond the bowl: our certifications
The recipe is the biggest lever, but it is not the only one. Petaluma is a Certified B Corporation, which means our social and environmental performance is independently audited. We carry The Climate Label, an independent climate certification, and we are a member of 1% for the Planet. Our food is baked, not extruded, in a solar-powered U.S. facility.

Frequently Asked Questions
What is the most sustainable dog food?
The most sustainable dog food is one with a measured, transparent footprint. Plant-based recipes tend to score best because animal protein drives most of pet food's impact. Per Petaluma's third-party life cycle assessments, our food lowers diet-related greenhouse gas, water, and land use by roughly 65 to 89% versus conventional kibble.
Is plant-based dog food actually better for the environment?
Yes, when it is nutritionally complete. A 2025 review in Frontiers in Sustainable Food Systems found plant-based pet diets consistently carried a lower environmental burden than meat-based diets, because growing plant protein uses less land, water, and energy than raising livestock.
How big is pet food's environmental footprint?
Larger than many people expect. Research in PLOS ONE attributes about a quarter to a third of the environmental impact of U.S. meat consumption to dogs and cats, and a Global Environmental Change study estimates dry pet food drives tens of millions of tons of emissions annually.
Does eco-friendly dog food mean lower nutrition?
It should not. Petaluma's recipes are formulated by veterinary nutritionists and meet AAFCO complete-and-balanced standards, with each nutritional profile verified through third-party laboratory testing. Sustainability and nutrition work together rather than against each other.
How do you know Petaluma's footprint numbers are real?
The figures come from third-party life cycle assessments, the standard method for measuring environmental impact. You can read the full adult and senior assessments yourself.
Is Petaluma a certified sustainable company?
Petaluma is a Certified B Corporation, carries The Climate Label, and is a member of 1% for the Planet. Our food is baked in a solar-powered U.S. facility. These are independent, audited programs rather than self-declared labels.
