Over the past decade, there has been a surge in the popularity of milk alternatives to traditional dairy milk. Options like soy, almond, oat, hazelnut, coconut, and rice milk are becoming more common. But if you’re trying to be environmentally friendly, which one should you choose? Let’s explore some of the most popular milk alternatives and rank them based on their impact on the environment, helping you make a smart choice when shopping.
We’ve been eager to start a series about the environment and climate change because these are some of the most pressing issues of our time. Understanding the environmental impact of our choices, like the type of milk we drink, is an important step in addressing these challenges.
First up is dairy milk. Studies, like one from Oxford University in 2018, show that dairy milk is not very eco-friendly. It produces three times more greenhouse gases than any plant-based milk and uses nine times more land. This is mainly because cows need a lot of feed, which requires large areas of land to grow. Dairy milk also uses a lot of water—about 120 liters for just one glass. So, if you’re aiming to be environmentally conscious, dairy milk might not be the best choice.
Rice milk is often cheaper than other alternatives, but it has a high environmental cost. It releases a lot of methane, a potent greenhouse gas, due to bacteria in rice paddies. The fertilizers used in rice farming can also pollute water sources. Plus, rice milk needs about 54 liters of water per glass, making it quite water-intensive.
Almond milk is a popular choice and uses less land than many other alternatives. However, it requires a lot of water—around 370 liters for a nearly liter-sized carton. Most almonds are grown in California, where water scarcity is a big issue. Additionally, almond farming relies heavily on commercial bees for pollination, which has raised concerns about bee health.
Coconut milk has a relatively low impact on land and water use, as it doesn’t require deforestation. However, the high demand for coconut products can lead to rainforest destruction in some areas. Most coconut milk comes from countries like Indonesia and the Philippines, so it’s important to choose fair trade brands to support ethical practices.
Soy milk is a strong contender, with low land and water use and low emissions. It also has a protein content similar to dairy milk. While there are concerns about phytoestrogens in soy, you would need to consume large amounts to see any negative effects. However, soy is often grown for animal feed, which can lead to deforestation. Choosing ethically sourced soy products can help reduce this impact.
Hazelnut milk is gaining popularity for its nutty flavor and lower environmental impact. Hazelnut trees help reduce greenhouse gases and are wind-pollinated, which is beneficial. However, there are human rights concerns in some regions, so it’s important to know where your hazelnut milk comes from.
Before we reveal the top alternative milk, here are a few honorable mentions. Pea milk reportedly produces only 25% of the emissions of dairy milk. Macadamia milk uses less water and is usually grown in areas with more water availability. Hemp milk is also environmentally friendly, often produced in small batches.
The current winner in the alternative milk category is oat milk. It uses very little water and land and has low emissions. Although a lot of oats are currently used for animal feed, there’s potential to shift more production to milk without a major environmental impact. Oats are grown in cooler climates, reducing the need for deforestation. The main concern with oat milk is that it’s a monoculture crop, which can make it vulnerable to pests and diseases, leading to pesticide use.
Overall, the differences between plant-based milks are relatively small compared to dairy milk. If you want to reduce your environmental footprint, switching to an alternative milk is a great step. Depending on your taste and dietary needs, you might want to try different options or rotate between them.

In the last decade or so, there’s been a renaissance of alternatives to dairy milk that are gaining popularity, including soy, almond, oat, hazelnut, coconut, rice milk, and many others. But which one should you actually be drinking if you want to be environmentally conscious? Today, we’re going to go through some of the most popular milk options and rate them from worst to best based on their environmental impact, so you can make an informed decision when you’re buying.
We’ve been wanting to start a series on this channel related to the environment and climate change for a while now. The climate crisis is going to be one of the biggest challenges of our time, so we want to think about it and talk about it as much as possible.
Up first is dairy milk. The general consensus is that dairy milk is not very good for the environment. An Oxford University study in 2018 found that dairy milk results in three times more greenhouse gas emissions than any alternative milk and nine times more land use, primarily due to the feed required for cows and the land needed to grow that feed. Dairy milk also uses a significant amount of water; a single glass (200 milliliters) requires about 120 liters of water to produce. So, if you’re looking for an environmentally-friendly milk, dairy isn’t the best option.
Our first alternative is rice milk. Rice milk is usually less expensive than other milk alternatives, but it ranks high in emissions due to the methane released by bacteria in rice paddies. Additionally, the fertilizers used can pollute waterways. Rice milk contributes three times the amount of fertilizer runoff compared to other alternatives. It also requires 54 liters of water per glass, making it quite water-intensive.
Next up is almond milk, which many people are familiar with. It requires less farmland than most other alternatives and has lower emissions, but it uses a lot of water—around 370 liters for a nearly liter-sized carton. Most almond farming occurs in California’s central valley, where drought is a concern, putting extra strain on the environment. Additionally, nearly 70% of commercial bees are used to pollinate almonds, and a significant number of these bees have faced threats in recent years.
Coconut milk has a fairly low impact on land and water use, as it doesn’t require deforestation. However, global demand for coconut milk can lead to rainforest clear-cutting in some regions. Most coconut milk comes from countries like Indonesia and the Philippines, and it’s important to look for fair trade brands to ensure ethical practices.
Soy milk is a strong alternative, ranking well in terms of land usage, water usage, and emissions. It also has a protein content similar to dairy milk. While there have been concerns about phytoestrogens in soy, research indicates that you would need to consume large quantities to see any negative effects. However, soy is often grown in large quantities for livestock feed, leading to deforestation in some areas. Choosing products from ethical sources can help mitigate this issue.
Hazelnut milk has gained popularity for its nutty flavor and lower environmental impact. Hazelnut trees help reduce greenhouse gas emissions and are wind-pollinated, which is beneficial. However, there are human rights concerns in some regions, so it’s important to know the source of your hazelnut milk.
Before we reveal our top alternative milk, there are a few honorable mentions with less research available. Pea milk reportedly creates only 25% of the emissions of dairy milk. Macadamia milk is a good alternative that uses less water and is typically grown in less water-scarce regions. Hemp milk is also considered environmentally friendly, as it’s often produced in small batches.
The current winner of the alternative milk battle is oat milk. It uses very little water and land and has low emissions. While a significant portion of oat production is currently used for animal feed, there’s potential to transition that production for milk without causing a larger environmental impact. Oats are grown in colder climates, reducing the need for deforestation. The main concern with oat milk is that it is a monoculture crop, making it susceptible to disease and pests, which can lead to pesticide use.
At the end of the day, the differences between these plant milks are relatively small compared to dairy milk. If you want to decrease your environmental impact, choosing an alternative milk is a good step. Depending on your personal taste and dietary restrictions, you might want to try different options or rotate through various kinds.
