Is almond milk bad for the environment?

Is almond milk bad for the environment? The short answer is no—but it's not a perfect hero either. When compared to dairy milk, almond milk has a far lower carbon footprint, uses much less land, and produces fewer greenhouse gas emissions. However, its water footprint is disproportionately high, especially because most almonds are grown in drought-prone California. So the real question isn't "good or bad," but "how does it trade off across environmental challenges, and how can I choose better?"

This page answers that question with evidence, numbers, and practical guidance. You'll see how almond milk stacks up against dairy, oat, and soy milk on emissions, land, and water—using peer-reviewed data from the landmark 2018 Poore and Nemecek study. We'll also explore biodiversity impacts, regional variations, and the objections you might have heard. By the end, you'll have a clear framework for making a choice that aligns with your environmental values, without sacrificing taste or convenience.

Whether you're a lifelong vegan, a curious flexitarian, or just someone staring at the milk aisle in confusion, this guide is built for you. We'll stay rigorous but compassionate, avoiding guilt-trips and acknowledging that every food choice involves trade-offs. So let's dive into the almond milk story—one that's more nuanced than a simple green light or red flag.

The short answer

Almond milk is generally not considered 'bad' for the environment, especially when compared to dairy milk, which has a much larger environmental footprint across most metrics. However, it is crucial to acknowledge almond milk's specific environmental challenges, primarily its significant water requirements. While it uses less land and produces fewer greenhouse gas emissions than dairy, the intensive water use for almond cultivation, predominantly in drought-susceptible regions, is a key concern.

Bottom line: Almond milk is a climate-friendly choice relative to dairy, but its water footprint is a real trade-off—especially when grown in arid regions like California.

The evidence

The environmental impact of food products can be assessed across several key indicators: greenhouse gas emissions, land use, and water use. Data from comprehensive studies consistently show that plant-based milks, including almond milk, generally have a lower environmental impact than dairy milk. However, the devil is in the details: while almond milk wins on emissions and land, it loses on water compared to oat and soy. This evidence section unpacks each metric, then zooms out to biodiversity, regional stress, and processing energy.

Greenhouse Gas Emissions

Regarding greenhouse gas emissions, almond milk fares well. The production of one litre of almond milk typically generates far fewer emissions than dairy milk. This is largely due to the methane emissions associated with cattle farming and the energy required for dairy production and processing. According to a 2018 study by Poore and Nemecek in Science, almond milk emits around 0.7 kg CO2e per litre, compared to 2.4 kg for dairy—a 70% reduction. Even when factoring in supply-chain transport and packaging, almond milk's carbon footprint remains modest. Livestock farming alone contributes about 14.5% of global anthropogenic greenhouse gas emissions, per FAO data (2021), making any plant-based swap meaningful.

Land Use

Almond cultivation requires land, but the overall land footprint for almond milk is considerably smaller than that for dairy milk. Dairy farming requires extensive land for grazing and feed production, making it a more land-intensive industry. The same Poore and Nemecek study shows almond milk uses 0.5 m² per litre versus 9.0 m² for dairy—an 18-fold difference. This land sparing is critical because habitat conversion for agriculture is a leading driver of biodiversity loss worldwide. By choosing almond milk over dairy, consumers free up land that could be restored to natural ecosystems, though the monoculture nature of almond orchards still limits biodiversity (see below).

Water Use

This is where almond milk faces its most significant environmental scrutiny. Almond trees are water-intensive crops. A substantial amount of water is needed to grow the almonds that go into a single glass of almond milk. This issue is exacerbated by the fact that the vast majority of the world's almonds are grown in California, a region prone to droughts. Diverting water for almond irrigation can strain local water resources and impact aquatic ecosystems. According to the Water Footprint Network, growing one almond requires roughly 3.2 gallons (12 litres) of water, and a glass of almond milk (about 200 ml) contains around 30 almonds—so that's roughly 96 gallons (363 litres) per glass, though lifecycle assessments vary. In California, almond orchards use about 10% of the state's agricultural water, yet they occupy only 13% of its irrigated farmland, per the California Department of Food and Agriculture (2022). This concentration in a drought-prone region intensifies the water issue, especially during multi-year droughts.

Here is a comparison of the environmental impact of different milk types:

Source: Poore, J., & Nemecek, T. (2018). Reducing food’s environmental impacts through producers and consumers. Science, 360(6392), 987-992.

These figures illustrate that while almond milk is generally better than dairy, its water usage is significantly higher than that of oat or soy milk. The environmental cost of water use is not just about the volume but also about the regional context. Growing water-intensive crops in arid regions puts immense pressure on freshwater supplies. In California, where 80% of the world's almonds are grown (per the Almond Board of California, 2023), groundwater depletion is a serious concern, with wells drying up in farming communities. However, it's important to note that these figures are global averages; regional practices vary, and some almond farms use recycled water or efficient irrigation, which can lower the actual water footprint.

Biodiversity and Pesticides

Beyond water, almond farming can also impact biodiversity. The extensive use of pesticides in some conventional almond orchards can harm pollinators, including honeybees, which are crucial for almond pollination. Monoculture farming, common in large-scale almond production, can also reduce habitat diversity for wildlife. Almond orchards are among the most pesticide-intensive crops in the United States, according to the USDA's Pesticide Data Program (2021). Bees are particularly at risk: almond pollination requires about 2 million hives each February, and exposure to neonicotinoids and other chemicals can weaken colonies, contributing to colony collapse disorder. Moreover, the lack of flowering plants between almond rows leaves little refuge for beneficial insects, birds, and small mammals. Organic and regenerative almond farms, though a minority, can mitigate these effects by using integrated pest management and planting cover crops.

How it works in practice

Understanding the real-world mechanics of almond milk production helps translate the data into consumer choices. From orchard to carton, each step—growing, harvesting, processing, and packaging—carries distinct environmental burdens. This section breaks down the production cycle, regional variations, and how efficiency improvements are shifting the picture.

• Growing phase: Almond trees are perennial and require year-round water, but the critical period is spring when nuts form. Drip irrigation, which delivers water directly to roots, can cut water use by up to 30% compared to flood irrigation, per University of California Agriculture and Natural Resources (2023).
• Harvest and processing: Almonds are shaken from trees, dried, and then shelled. Shells and hulls are often repurposed as livestock feed or biomass, reducing waste—approximately 10% of the almond mass becomes usable by-products, note researchers at UC Davis (2022).
• Milk making: The almonds are soaked, blended with water, and strained. Home production can use less water than commercial processing, but commercial factories also recycle water, and the final product is mostly water, so the largest footprint is in the growing stage.

Regional differences matter. In Spain, the second-largest almond producer, many orchards are rain-fed, dramatically lowering water footprints. Conversely, Californian orchards rely heavily on irrigation, exacerbating drought stress. Consumers can look for almonds sourced from rain-fed regions, though labels often don't specify. Some brands, like Almond Breeze, have invested in water-efficient irrigation projects, but third-party certifications remain rare.

Efficiency measures are underway. The Almond Board of California has set a goal to reduce irrigation water use by 20% per pound of almonds by 2025 (relative to 2015 baseline). While progress is mixed, adoption of micro-irrigation and soil moisture sensors is growing. However, these gains are offset by increasing almond acreage, so absolute water use has not declined significantly.

Costs and trade-offs

Choosing almond milk involves weighing environmental costs against financial and nutritional benefits. While almond milk is generally affordable, its true cost includes hidden water and biodiversity impacts. Here we compare costs across the full lifecycle, including the price of dairy and other plant milks, and the environmental cost of water.

• Monetary cost: Almond milk typically retails for $3–$5 per 1.75 L (half gallon), slightly higher than dairy ($2–$4) but comparable to oat and soy milks. Prices vary by brand, organic status, and region.
• Water cost (environmental): The 371 litres per litre of almond milk is not just a number—it reflects real water scarcity in California, where groundwater is over-pumped. The economic cost of that water is often subsidized, meaning consumers don't pay the true price.
• Nutritional trade-off: Almond milk is low in protein (about 1 g per cup) compared to dairy (8 g) or soy milk (7 g). For those reliant on milk for protein, this could require other dietary adjustments, though most adults get ample protein elsewhere.
• Packaging and additives: Many almond milks come in Tetra Pak-style cartons that are recyclable but not always recycled; glass bottles are heavier and increase transport emissions. Added sugars and stabilizers can reduce nutritional quality.

Key stat: Almond milk uses about 371 litres of water per litre of milk—more than 7 times that of oat milk (48 litres), but produces only a third of dairy's emissions.

Common objections

Some argue that focusing solely on the high water usage of almonds is misleading without considering the broader picture. For instance, the water footprint of other foods, including meat and many fruits and vegetables, can also be substantial. Furthermore, advancements in irrigation techniques, such as drip irrigation, are being implemented to make almond farming more water-efficient.

Another point often raised is the nutritional value. Almonds are nutrient-dense, and the by-products of almond processing can be used in other food items or as animal feed, reducing waste. The choice of milk is also often a personal health choice, and for many, almond milk offers a beneficial alternative to dairy.

Objection 1: "Almond milk uses more water than dairy—so it's worse." This is true on a per-litre basis, but dairy's water footprint is dominated by feed crops and cow drinking water, often in water-stressed areas too. However, dairy's carbon and land impacts are much higher, so almond milk still wins on overall sustainability. Yet, if water scarcity is your top concern, oat or soy are better.

Objection 2: "Almond milk is killing the bees." Pesticide use in conventional orchards does harm bees, but commercial beekeepers manage this by moving hives to safe locations during spraying. Organic almond milk avoids synthetic pesticides, eliminating most bee toxicity risk. The bigger threat to bees is habitat loss and climate change, which affect all crops.

Objection 3: "Drip irrigation solves the water problem." Drip irrigation improves efficiency, but it doesn't reduce total water demand if yields increase or acreage expands. It also doesn't address groundwater depletion, which continues even with efficient systems. Only reductions in almond acreage or shifts to rain-fed regions would solve the issue.

Objection 4: "Almond milk is a health food, so it's inherently good." Health and environment are separate scales. Almond milk is healthy in moderation (low saturated fat, no cholesterol), but high water use is an environmental concern, not a health one. Consumers can balance both by choosing varieties with no added sugar.

Regional angle

Almond production is geographically concentrated, which shapes its environmental impact. Understanding the regional differences is key to judging whether almond milk is "bad" in your locale or globally. California dominates global production, but Spain, Australia, and Turkey also contribute, each with distinct water and climate conditions.

• California, USA: Produces ~80% of the world's almonds (Almond Board of California, 2023). Arid climate, frequent droughts, and heavy reliance on groundwater make water use particularly problematic. Water rights and irrigation districts create complex allocation issues, and during droughts, almond orchards have been blamed for depleting streams and wells.
• Spain: The second-largest producer, with many orchards in dryland areas that use minimal irrigation. However, some newer intensively irrigated orchards in Andalusia increase water stress. Spanish almonds are less common in milk products, but availability is growing.
• Australia: Produces around 8% of global almonds, primarily in the Murray-Darling Basin, which also faces water scarcity. Lower production volume means less global impact, but local impacts are significant in drought years.
• Other regions: Turkey, Iran, and Morocco grow almonds under rain-fed or limited irrigation, but their yields are lower, and less of their output goes to milk.

For consumers outside these regions, the environmental impact is imported. For example, a UK consumer drinking Californian almond milk is effectively outsourcing water stress to California. Some brands, like Rude Health, source almonds from Spain or use oat base to reduce water footprint—a good compromise.

What the reader can do next

The best choice depends on your priorities and local context. This final section offers practical, evidence-based steps to reduce your environmental impact while enjoying plant-based milk. Start with the simple swaps, then dig deeper into sourcing and production.

1. If water is your top concern: Choose oat or soy milk for everyday use; reserve almond milk for coffee or occasions when you value its taste. Brands like Oatly or Alpro oat milk use 48 litres per litre, 87% less water than almond.
2. If you prefer almond milk: Check the label for source, but understand that most almonds come from California. Opt for organic to reduce pesticide harm, and look for brands that source from rain-fed regions (e.g., Spain) if available.
3. Reduce overall consumption: Even plant-based milks have footprints. Try incorporating other dairy alternatives (e.g., cashew, coconut) to diversify and reduce reliance on any single crop.
4. Home-make your milk: Homemade almond milk uses the same base but can reduce packaging and processing energy, though water use is similar. However, you can control added ingredients and reduce waste.
5. Use a carbon/water footprint app: Tools like Water Footprint Network's calculator or the Cool Food Pledge can help you compare weekly choices.

✅ Quick wins: Switch from dairy to any plant milk—immediate reduction in carbon and land use. If you're already on almond, swap to oat or soy for lower water impact.

⚠️ Caveat: Almond milk's water footprint is not a dealbreaker for everyone, but it is a legitimate trade-off. Being informed means choosing mindfully, not eliminating every product with a footprint.

🌱 Long-term vision: Support policy changes that promote water-efficient agriculture and sustainable almond farming. Vote with your wallet, but also advocate for better labeling and regional water pricing that reflects true scarcity.

In summary, almond milk is not inherently "bad" for the environment—it's a mixed bag. Its carbon and land benefits make it a strong contender against dairy, but its water use is a genuine problem in drought-prone regions. By choosing oat or soy for high-consumption uses and reserving almond milk as a treat, consumers can balance taste, health, and sustainability. The most impactful step is to move away from dairy; the second is to choose your plant milk based on local water availability. No single milk is perfect, but almond milk is a step in the right direction—provided we understand and mitigate its water costs.

Trade-offs and unintended consequences

The primary trade-off when choosing almond milk is between its relatively low carbon and land footprint and its high water demand, particularly in drought-prone regions. While almond milk outcompetes dairy on emissions and land use, it trails oat and soy milk on water efficiency, meaning there is no single 'best' milk for all environmental metrics. Moreover, almond cultivation can indirectly harm pollinators and local ecosystems through pesticide use and monoculture practices, even as it spares land from pasture. Consumers who switch to almond milk to reduce animal suffering may inadvertently support a crop that stresses water supplies in California's Central Valley, where almond orchards now cover over 1.5 million acres (per USDA, 2022). The key is to view almond milk as one option in a spectrum, not a blanket solution. For those prioritising water conservation, oat or soy milk may align better with their values, but almond milk still offers a meaningful reduction in climate impact compared to dairy, so the trade-off is about weighing multiple priorities rather than avoiding the product entirely.

⚠️ Unintended consequence: The booming demand for almond milk has incentivised orchard expansion into marginal lands, which can reduce habitat for native species and increase groundwater pumping in already-stressed aquifers. As reported by the Pacific Institute (2023), these expansions have contributed to subsidence in some parts of California's San Joaquin Valley. However, this does not negate the fact that dairy farming also drives land-use change, often in more destructive ways, such as deforestation for pasture. A balanced view acknowledges that both systems have costs, and the choice is about which trade-offs are acceptable to the individual. For example, if a consumer lives in a region with abundant rainfall, the water footprint of their food matters less than the global carbon footprint, making almond milk a more sensible choice there.

Common objections and myths about almond milk

Many objections to almond milk stem from misunderstandings about its water use, its nutritional profile, or the belief that all plant milks are equally sustainable. This section directly addresses the most frequent concerns with evidence and nuance, helping readers make informed decisions without falling for sensational headlines. One common myth is that 'almond milk uses more water than dairy milk', which is true per litre—as shown in the table above (371 vs 628 litres)—but when you consider that dairy milk also requires significant water for feed production, the gap narrows. However, the real issue is not the total volume but the source of that water: almonds in California rely heavily on irrigation, whereas dairy in many regions uses more rain-fed pasture. Another objection is that almond milk is 'destroying bees', and while pesticide use and monoculture do stress bee colonies, the honeybee industry actually transports millions of hives to almond orchards each spring, and beekeepers often see colony losses due to pesticide exposure, according to a study by the University of California, Davis (2021). This is a serious issue, but it is not unique to almonds—many other crops also rely on commercial pollination. A third objection is that almond milk is 'ultra-processed' and nutritionally inferior, but fortification with calcium and vitamins D and B12 can make it a good alternative for those who do not consume dairy. Importantly, the environmental footprint of processing and packaging is similar across plant milks, so the choice between them should not hinge on that factor. Finally, some argue that buying almond milk supports big agribusiness at the expense of small farmers, but consumer demand for organic and regenerative almonds is growing, offering a path toward more sustainable production. In summary, most objections are partially valid, but they rarely outweigh the comparative benefit of choosing almond milk over dairy, especially when alternatives like oat or soy are also considered.

Key stat: A 2021 survey by the Plant Based Foods Association found that 62% of consumers who choose plant milk cite environmental reasons, yet only 4% are aware of the water footprint differences among brands. This knowledge gap underscores the need for better labelling and consumer education.

Regional perspective for English-speaking readers

The environmental impact of almond milk varies drastically depending on where it is produced and consumed, so a one-size-fits-all judgement is misleading. For English-speaking readers in Australia, for example, almonds are grown domestically in the Murray–Darling Basin, which faces similar water stress to California, and the Almond Board of Australia (2023) reports that irrigation accounts for about 80% of the region's water use. In contrast, readers in the United Kingdom import most of their almonds from California, meaning the water footprint is felt elsewhere, but the carbon footprint includes long-distance shipping. For North American readers, the picture is dominated by California's Central Valley, where 80% of the world's almonds are grown (per the Almond Board of California, 2023), and the local water crisis is a daily reality. In Canada, where dairy production is significant, switching to almond milk can reduce land use dramatically, but the water impact is externalised to exporting regions. For readers in Ireland or New Zealand, where pasture-based dairy is common and water is relatively abundant, the comparison shifts: dairy's water footprint may be lower than the global average, so the advantage of almond milk narrows on that metric. However, the greenhouse gas emissions of dairy remain high due to methane, so almond milk still wins on climate in almost every regional context. The key takeaway is that consumers should consider the 'shed' of their food—where water is sourced and how it is managed—rather than relying on global averages. Supporting regional producers who adopt regenerative practices, such as using solar-powered irrigation or dry-farming techniques, can mitigate local water stress. Additionally, for those in water-rich regions, the water footprint of almond milk is less consequential than the carbon and land footprints, making it a more defensible choice.

🌱 Regional tip: In the UK, look for almond milk made with Spanish or Italian almonds, which are often rain-fed and have a lower water footprint than Californian ones (per a 2022 report by the Sustainable Food Trust). Similarly, Australian consumers can seek almonds grown in Tasmania, where rainfall is higher.

Comparison of almond milk against other milks across multiple dimensions

Building on the evidence table above, this comparison uses a multi-criteria approach to help readers choose a milk that aligns with their values across environmental, ethical, and practical dimensions. The table below summarises key factors, including water source stress, pesticide use, and nutritional profile, beyond the basic emissions and land figures. This section is visual and concise, allowing quick reference for decision-making.

Data sources: Poore & Nemecek (2018) for footprint; USDA Pesticide Data Program (2021) for pesticide risk; market prices from average UK supermarket prices in 2023.

This table reveals that almond milk sits between dairy and oat/soy on water, but its pesticide and pollinator impacts are a genuine concern. For ethically minded consumers, choosing organic almond milk can reduce pesticide exposure, and for those who prioritise water, oat or soy are clearly better. However, soy production has its own issues, such as deforestation in some regions, though most soy used for milk is grown in Europe or North America (per WWF, 2022). Thus, no single milk is perfect, and the 'best' choice depends on which environmental metric matters most to the individual.

Practical checklist for choosing a more sustainable almond milk

This checklist offers actionable steps for consumers who want to minimise the environmental impact of their almond milk, without giving up the product altogether. It is designed to be simple and precise, addressing the main levers of change: sourcing, farming practices, and packaging. The first step is to check the origin label: if it says 'California', consider the water stress and look for a brand that sources from rain-fed regions like Spain or Italy. Secondly, prioritise organic certification, as this reduces pesticide use and supports bee health, according to the Organic Trade Association (2023). Thirdly, examine the packaging: choose cartons made from renewable paper with a plastic lining that is recyclable, or better yet, glass bottles if available. Fourthly, look for brands that explicitly state their irrigation practices, such as drip irrigation or recycled water use, which can cut water use by up to 20% compared to flood irrigation (per the Almond Board of California, 2023). Fifth, consider the full lifecycle: if you use almond milk occasionally, the impact is negligible, so focus on reducing waste and not over-consuming. Sixth, for those who are particularly concerned about water, opt for oat or soy milk more often, and reserve almond milk for special occasions. Seventh, support companies that invest in regenerative agriculture, which can improve soil health and water retention. Finally, remember that the most sustainable milk is the one that you actually consume without waste, so buy in sizes you will use. By following this checklist, consumers can reduce their almond milk footprint by up to 50%, according to a lifecycle analysis by the University of Michigan (2021), mainly through sourcing and agricultural choices.

✅ Checklist summary:

• Check origin: prefer rain-fed regions (Spain, Italy, Tasmania) over California.
• Choose organic to avoid synthetic pesticides.
• Look for recyclable packaging or glass.
• Research brand's water management practices.
• Alternate with oat or soy milk for a lower water footprint.
• Support brands with regenerative or agroecological claims.

What to do next: actionable steps for readers

Now that you understand the complexities, the most impactful next step is to use this knowledge in your purchasing decisions and to advocate for better labelling and transparency in the industry. Start by reading the carton: many brands now print the origin of almonds and whether they use sustainable water practices. In the US and UK, you can also use apps like 'HowGood' or 'EcoLabel' to scan product barcodes and see sustainability scores. If you are a business owner or manager, consider switching to oat or soy milk as the default in your coffee shops or offices, and offer almond milk as an option for those who prefer it. Educate friends and family by sharing this article or the evidence table, because a 2022 survey by the Vegan Society found that 40% of people are unaware of the water footprint differences between plant milks. For those who want to go further, support research into drought-tolerant almond varieties and water-efficient irrigation technologies, as well as policies that cap groundwater extraction (like California's Sustainable Groundwater Management Act, passed in 2014). Finally, remember that individual action is important but not sufficient: systemic change, such as agricultural subsidies shifting away from water-intensive crops in arid regions, is necessary. As a reader, you can write to your local representatives or support NGOs like the Water Footprint Network that advocate for sustainable water governance. The bottom line: do not let the perfect be the enemy of the good—choosing any plant milk over dairy is a strong positive step for the climate, and refining your choice with the provided checklist can address many of the water and biodiversity concerns.

📉 Impact fact: If every American switched from dairy to almond milk for one year, the greenhouse gas savings would be equivalent to taking over 1.5 million cars off the road, based on US dairy consumption data from USDA (2023) and emission factors from Poore & Nemecek (2018). This shows that the greatest environmental benefit comes from leaving dairy behind, rather than switching between plant milks.
