Almondmilk vs Oatmilk: Which Has a Lower Environmental Impact?

As more consumers shift toward plant-based diets, the environmental footprint of their food choices has come under scrutiny. Almondmilk and oatmilk are two of the most popular dairy alternatives, but they have vastly different environmental impacts. While both are far more sustainable than cow's milk, understanding the nuances can help you make a more informed, eco-conscious choice.

This article dives into the key sustainability factors: water usage, carbon emissions, land use, and agricultural practices. We'll also highlight how brands like Mooala are making it easier to choose responsibly with products like their Unsweetened Almondmilk and Original Oatmilk.

Water Usage: Almondmilk's Biggest Challenge

Almond cultivation is notoriously water-intensive. It takes approximately 1,611 gallons of water to produce one gallon of almondmilk, largely because 80% of the world's almonds are grown in drought-prone California. In contrast, oats require significantly less water—about 290 gallons per gallon of oatmilk. This makes oatmilk a far more water-efficient choice, especially in regions facing water scarcity.

However, not all almondmilk is equal. Some almond farms use drip irrigation and water recycling to reduce consumption. When choosing almondmilk, look for brands that source from farms with sustainable water management practices. Mooala's Unsweetened Almondmilk, for example, is made with almonds grown using responsible farming methods, offering a more eco-friendly option.

• Almondmilk: ~1,611 gallons of water per gallon of milk produced
• Oatmilk: ~290 gallons of water per gallon of milk produced
• Oatmilk uses about 82% less water than almondmilk

Carbon Footprint: Which Milk Emits Less CO2?

When it comes to greenhouse gas emissions, both almondmilk and oatmilk outperform dairy milk by a wide margin. Dairy milk emits around 3.2 kg CO2 equivalent per liter, while almondmilk emits about 0.7 kg and oatmilk about 0.9 kg. Though oatmilk has a slightly higher carbon footprint than almondmilk, the difference is small and often offset by other environmental benefits.

The carbon footprint of oatmilk is influenced by the energy used in processing and transportation. Oats are typically grown in cooler climates like Canada and Northern Europe, which can mean longer shipping distances. Almondmilk, on the other hand, benefits from local California production for U.S. consumers. Still, the overall impact remains low for both options.

• Dairy milk: 3.2 kg CO2e per liter
• Almondmilk: 0.7 kg CO2e per liter
• Oatmilk: 0.9 kg CO2e per liter

Land Use and Biodiversity

Almond farming requires dedicated orchards that occupy large swaths of land, often at the expense of natural habitats. In California, almond orchards have replaced diverse ecosystems, contributing to a decline in pollinator populations. Oats, by contrast, are typically grown as part of a crop rotation system that can improve soil health and support biodiversity.

Oats also require less land per gallon of milk produced. A study from the University of Oxford found that oatmilk uses about 0.3 square meters of land per liter, while almondmilk uses about 0.5 square meters. This makes oatmilk a more land-efficient choice, especially for consumers concerned about deforestation and habitat loss.

• Almondmilk: ~0.5 m² of land per liter
• Oatmilk: ~0.3 m² of land per liter
• Oat farming supports crop rotation and soil health

Pesticides and Agricultural Practices

Almond orchards are heavily reliant on pesticides, particularly during the blooming season when honeybees are brought in for pollination. This has been linked to colony collapse disorder and other bee health issues. Oats, on the other hand, are typically grown with fewer chemical inputs and are often rotated with other crops to naturally manage pests.

For consumers who prioritize organic or low-pesticide options, oatmilk may be the safer bet. However, some almondmilk brands are moving toward regenerative agriculture. Mooala's Original Oatmilk is made from oats grown without synthetic pesticides, making it a cleaner choice for both your body and the planet.

• Almond farming uses high pesticide loads, harming pollinators
• Oat farming uses fewer chemicals and supports crop rotation
• Choose organic or low-pesticide options when possible

Packaging and Shelf-Stable Benefits

Both almondmilk and oatmilk are often sold in aseptic cartons that are shelf-stable for months. This packaging reduces food waste and lowers transportation emissions because products can be shipped without refrigeration. Shelf-stable cartons are also widely recyclable, though consumers should check local recycling guidelines.

Mooala offers both almondmilk and oatmilk in shelf-stable formats, such as their Unsweetened Almondmilk and Original Oatmilk. These products eliminate the need for cold chain logistics, further reducing their carbon footprint. By choosing shelf-stable options, you support a more efficient supply chain.

• Shelf-stable cartons reduce food waste and transport emissions
• Aseptic packaging is recyclable in many areas
• Mooala's shelf-stable milks are convenient and eco-friendly

Choosing between almondmilk and oatmilk ultimately depends on your priorities. If water conservation is your top concern, oatmilk is the clear winner. If you're focused on carbon emissions, almondmilk has a slight edge, but the difference is minimal. Both options are vastly more sustainable than dairy milk. For a balanced, eco-friendly choice, consider incorporating both into your diet. Explore Mooala's Unsweetened Almondmilk for a low-carbon option or their Original Oatmilk for a water-wise alternative. Every small swap makes a difference for our planet.
