Oatmilk vs Almondmilk: Which Plant-Based Milk Has a Lower Environmental Impact?

Plant-based milks have surged in popularity, but not all are created equal when it comes to sustainability. Oatmilk and almondmilk are two of the most popular dairy alternatives, yet their environmental footprints differ significantly. Understanding these differences can help you make a more informed, eco-friendly choice.

From water scarcity to greenhouse gas emissions, we break down the key factors that determine which milk is truly greener. Whether you're a dedicated environmentalist or just starting to think about your carbon footprint, this comparison will guide you toward the most sustainable option for your morning coffee, smoothie, or baking.

Water Usage: Almondmilk’s Biggest Environmental Challenge

Almondmilk has a well-documented water problem. It takes approximately 1,611 gallons of water to produce just one gallon of almond milk, primarily because almonds are a water-intensive crop grown in drought-prone regions like California. In contrast, oatmilk requires only about 48 gallons of water per gallon, making it far more water-efficient. This stark difference is a major consideration for eco-conscious consumers, especially in areas facing water scarcity.

While some almond growers have adopted more efficient irrigation methods, the overall water footprint remains high. If reducing water usage is a top priority for you, oatmilk is clearly the more sustainable choice. Brands like Mooala offer delicious oatmilk options that are both creamy and environmentally responsible.

Carbon Footprint: Which Milk Emits Fewer Greenhouse Gases?

When it comes to greenhouse gas emissions, oatmilk again takes the lead. Studies show that oatmilk produces about 0.9 kg of CO2 equivalent per liter, while almondmilk emits around 1.2 kg per liter. Though both are far lower than dairy milk (which can exceed 3 kg per liter), oatmilk’s lower emissions are due to oats being a low-input crop that requires less fertilizer and energy to grow.

Additionally, oatmilk often uses less land and fewer pesticides than almonds. For those looking to minimize their climate impact, choosing oatmilk over almondmilk can make a measurable difference. Mooala's Original Oatmilk is a great option for everyday use, from cereal to cooking.

Land Use and Biodiversity: A Complex Trade-Off

Almond farming requires dedicated orchards that take years to become productive, and they often displace natural habitats. Oats, on the other hand, are a rotational crop that can be grown in many climates without permanent land conversion. This makes oatmilk generally better for biodiversity. However, almond trees do sequester carbon while growing, which slightly offsets their footprint.

It's also worth noting that almonds are a source of pollination demand, which can stress bee populations. Oat farming does not rely on bees, making it a more bee-friendly choice. If you're concerned about pollinator health, oatmilk is the safer bet.

• Oats are a rotational crop that improves soil health.
• Almond orchards require permanent land use and intensive bee management.
• Oatmilk production supports greater biodiversity in agricultural systems.

Packaging and Transport: Shelf-Stable Options Reduce Waste

Both oatmilk and almondmilk are available in shelf-stable packaging, which extends shelf life and reduces food waste. Shelf-stable cartons also allow for more efficient shipping since they don't require refrigeration during transport. This lowers the overall carbon footprint compared to refrigerated alternatives.

Mooala offers shelf-stable versions of both oatmilk and almondmilk, making it easy to stock up without worrying about spoilage. Their Barista Oatmilk is especially popular for coffee lovers who want a creamy, frothy texture without the environmental guilt.

Which Plant-Based Milk Should You Choose?

If your primary goal is to minimize water usage and greenhouse gas emissions, oatmilk is the clear winner. It uses less water, emits fewer greenhouse gases, and supports better land use practices. However, if you have a nut allergy or prefer the taste of almondmilk, choosing a brand that sources almonds from water-efficient farms can help mitigate some concerns.

Ultimately, both oatmilk and almondmilk are far more sustainable than dairy milk. The best choice is the one you'll actually use regularly, as any plant-based milk is a step in the right direction. For a balanced pantry, consider keeping both on hand for different recipes.

Making the switch to plant-based milk is one of the simplest ways to reduce your environmental footprint. Whether you choose oatmilk for its low water use or almondmilk for its taste, every small change adds up.
