Cheese is a beloved food for many, but it has a high environmental footprint. Livestock generates significant greenhouse gases, and cheese requires a lot of milk—around 10 pounds of milk to produce a pound of hard cheese. This means that ruminants like cows, goats, and sheep, which are well-adapted to eating grass, also burp methane during digestion, contributing to the carbon footprint of cheese production. While some sources suggest that goat cheese is similar to cow cheese in terms of emissions, others indicate that goat milk is responsible for twice the amount of greenhouse gas emissions as cow milk. However, goats require less space and produce more milk from the same amount of food, and some studies suggest that goat cheese may be comparable to or even better than cow cheese in terms of CO2 impact per litre. Overall, the key factors influencing the environmental impact of cheese include the type of livestock, the amount of milk needed, the processing and aging involved, and the transportation and packaging methods used.
| Characteristics | Values |
|---|---|
| Carbon footprint | Goat cheese has a similar carbon footprint to cow's cheese, with goat milk being responsible for twice the amount of greenhouse gas emissions as cow milk. |
| Methane emissions | Goats, like cows and sheep, are ruminants, which means they burp methane during the digestion of grass. A single cow produces around 100 kg of methane each year. |
| Water usage | It takes 10 pounds of milk, which requires 5,000 liters of water, to produce a pound of hard cheese. |
| Processing | Younger, softer, and less processed cheeses are more environmentally friendly because they require less milk, less aging, and less electricity to maintain a cool temperature. |
| Transportation | Cheese produced by local and small-scale cheese producers is more sustainable because it reduces the carbon footprint associated with long-distance transportation. |

Goat cheese vs. other cheeses
Cheese is a high-carbon-footprint food item, and it is difficult for cheese lovers to give up. The carbon footprint of cheese comes from the fact that it takes a lot of milk to produce a pound of cheese—approximately 10 pounds of milk, on average, go into producing a pound of hard cheese.
Goat cheese is often considered a more environmentally friendly option than other cheeses, but the reality is more complex. Goat cheese has a similar environmental impact to cow's cheese, and both are considered better options than sheep's cheese. This is because, although all three animals (cows, goats, and sheep) are ruminants that burp methane during grass digestion, cows produce a larger volume of milk than goats and sheep, and goats produce more milk than sheep from the same amount of food. Therefore, the emissions caused by the lower milk yield of goats and sheep are not entirely offset by the higher milk yield of cows.
The impact of goat's milk is 1.5 times that of cow's milk, and sheep's milk is twice as impactful. However, there is a lot of variation in the data, and some goat and sheep milk products have similar or even lower CO2 impacts per litre than cow's milk. The type of cheese also matters; softer, less dense cheeses with lower fat content tend to have a lower environmental impact because they require less milk to produce. For example, fresh cheese like cottage cheese requires around 4 litres of milk, while hard cheese requires 9 to 10 litres.
The processing and aging of cheese also play a role in its environmental impact. Younger cheeses are more energy-efficient because they do not require as much electricity for refrigeration as older cheeses. Additionally, the environmental impact of cheese production can be reduced by supporting local, sustainable, and organic producers who use well-managed, grass-fed systems. These practices generate fewer environmental impacts, are more ethical, and produce more nutritious output.

Impact of methane emissions
Methane is a significant contributor to the carbon footprint of cheese production. Ruminants, including goats, burp methane during the digestion of grass, and methane is a powerful greenhouse gas. Each year, one cow can belch 220 pounds of methane, which is 28 times more potent than carbon dioxide in warming the atmosphere. While cows and other ruminants account for just 4% of all greenhouse gases produced in the United States, according to Professor Frank Mitloehner, an air quality specialist in the Department of Animal Science, ruminants in particular create a lot of methane, and this has led to calls for people to eat less beef.
Goats, sheep, and cows are all ruminants, and their milk has different compositions in terms of fat and protein content. This means that there is no single value for the environmental impact of their milk or cheese. On average, the impact of goat's milk is 1.5 times that of cow's milk, and sheep's milk is twice that of cow's milk. However, the data varies, and there are goat and sheep milk products with similar CO2 impacts per litre to those of cows.
The conversion from milk to cheese does not significantly add to emissions when measured against protein content. This indicates that the environmental impact of cheese is largely dependent on the type of livestock used for milk production. Goat and cow cheese have been described as equally detrimental to the environment, while sheep cheese is said to be even worse. However, it is important to note that the lower the fat content of the cheese, the less the climate impact, which means that soft cheeses like mozzarella or cottage cheese have a smaller environmental footprint than hard cheeses.
To reduce methane emissions from livestock, researchers are experimenting with feed additives, such as red seaweed, that have proven effective in reducing enteric methane emissions. Sustainable grazing practices can also help to offset methane emissions, and selective breeding of low-methane cattle could substantially cut enteric methane emissions by about 19% by 2030. While methane emissions from livestock are a concern, it is important to note that methane emissions from fossil fuel production and use are more serious than those from animal agriculture.

Carbon footprint of goat milk
Goat milk has a smaller environmental impact than cow milk, but a larger impact than dairy milk from cows. This is due to several factors, including the amount of milk produced, the feed conversion ratio, and the enteric methane emissions of goats.
A study on the carbon footprint of dairy goat milk production in New Zealand found that indoor farms produced an average of 11.05 tonnes of CO2e per hectare, while outdoor farms produced 5.38 tonnes of CO2e per hectare. The choice of manure management system and supplementary feed can substantially affect the carbon footprint. Nitrous oxide emissions from manure management can contribute up to 18% of total emissions.
Goats require less space and produce more milk from the same amount of food compared to cows. This means that goat milk has a lower feed conversion ratio, which results in lower land and water usage for feed production. According to a study published in the Journal of Animal Science, today's dairy producers use only 10% of the land, 23% of the feedstock, and 35% of the water that was used to produce the same amount of milk in 1944.
However, one of the main concerns with goat milk is the high methane emissions associated with ruminants. Ruminants, such as goats, burp methane during the digestion of grass, and methane is a potent greenhouse gas. The Lassey method, used in the New Zealand greenhouse gas inventory, provides a more robust estimate of emissions from enteric fermentation and is considered a reliable tool for assessing the carbon footprint of goat milk production.
While goat milk may have a slightly lower environmental impact than cow milk in some aspects, it is important to consider the overall sustainability of dairy products. Reducing the consumption of dairy products or choosing plant-based alternatives can be more effective in mitigating the environmental impact of the dairy industry. Individual actions, such as reducing cheese consumption or choosing low-fat cheese varieties, can also contribute to reducing the carbon footprint of dairy products.

Environmental impact of production
The environmental impact of cheese production is significant. According to the Environmental Working Group (EWG), cheese is the third-worst food in terms of climate impact, surpassed only by beef and lamb. The production of cheese involves a high carbon footprint due to the large amount of milk required, with around 10 pounds of milk needed to produce a pound of hard cheese. This leads to excessive water usage, with 5000 litres of water required to make one kilogram of cheese.
Goat cheese, in particular, has a similar environmental impact to cow's cheese. While goats require less space and produce more milk from the same amount of food, they emit methane during digestion, a powerful greenhouse gas. Goat milk is responsible for twice the amount of greenhouse gas emissions as cow milk, according to the UN Food and Agriculture Organization. However, goats in the United States and New Zealand may be more efficient, with comparable emissions to cows.
The type of cheese also impacts the environment. Soft cheeses tend to be greener than hard cheeses as the latter requires more milk, more aging, and longer cooking times. Younger cheeses are also more energy-efficient than aged cheeses due to the electricity required for refrigeration. Lower-fat cheeses have lower emissions because the removal of fat from the cheese-making process reduces the climate impact, and toxins build up in fat.
To reduce the environmental impact of cheese consumption, individuals can embrace sustainable practices. This includes reducing portion sizes, choosing local and small-scale cheese producers to lower transportation emissions, and supporting sustainable brands that use energy-efficient processes and eco-friendly packaging.

Sustainable cheese consumption
Cheese is one of life's great pleasures, but it's also a food with a significant environmental impact. The good news is that there are ways to enjoy cheese while being mindful of sustainability. Here are some tips for sustainable cheese consumption:
Choose the Right Type of Cheese
Not all cheeses are created equal when it comes to sustainability. The production of different types of cheese can have varying impacts on the environment. Soft cheeses, for example, tend to be more sustainable than hard cheeses since they require less milk and a less extensive aging process. Younger cheeses are also more energy-efficient than aged varieties because they require less electricity for cooling during aging. Additionally, when it comes to milk sources, goat and cow cheeses have been found to have similar environmental impacts, while sheep cheese tends to be worse due to higher greenhouse gas emissions per unit of cheese.
Reduce Serving Sizes
One of the most effective ways to make your cheese consumption more sustainable is to reduce your serving sizes. Treat cheese as a luxury item and use smaller amounts of stronger-tasting cheeses. For example, a small amount of fresh goat cheese or feta can provide more flavour than larger amounts of milder cheeses like ricotta or mozzarella. Grating your own Parmesan can also help you use less while maximizing flavour.
Support Sustainable Practices
As a consumer, you have the power to support sustainable practices in the cheese industry. Look for cheese producers that are transparent about their environmental practices and animal welfare standards. Some cheesemakers are certified as Animal Welfare Approved, ensuring best practices for their animals, which can result in superior-quality milk. You can also support creameries and dairy industries that are committed to environmentally friendly practices, such as adjusting cows' diets to include seaweed, which reduces methane production.
Mindful Consumption and Storage
Practising mindful consumption and storage can also contribute to sustainability. Consider setting a cheese budget for yourself, buying only the amount you need for the week, and avoiding waste. Properly storing leftovers is also important for reducing waste and protecting your purchases.
Explore Alternatives
If you're open to trying something new, you can explore alternative options that offer the taste and experience of cheese without the same environmental impact. For example, you can try vegan cheeses made from nut-derived or plant-based sources, reducing the impact associated with dairy production.
In conclusion, by following these tips and adopting a sustainable mindset, you can continue to enjoy cheese while being mindful of its environmental impact. Remember, individual actions, no matter how small, can collectively make a significant difference.
