What You'll Learn
Cheese production's environmental impact
Cheese is a food product with a substantial environmental impact. It is considered worse for the environment than many types of meat, including chicken. This is due to several factors, including the amount of methane emitted by cows, the resources required to raise cows, and the carbon footprint of cheese production and transportation.
One of the main reasons cheese production is harmful to the environment is the significant amount of methane emitted by cows. Methane is a potent greenhouse gas that contributes to global warming. Cows emit methane through their belching and waste, and the amount of methane emitted is influenced by the cow's diet. For example, feeding cows seaweed has been found to reduce methane production and, consequently, greenhouse gas emissions.
Additionally, raising cows requires a significant amount of resources, including water, feed, and land. The feed for cows, such as corn and alfalfa, requires land and resources to produce, contributing further to the environmental impact of cheese production. Furthermore, the milk required to make cheese is water-intensive, and the production and transportation of milk contribute to the carbon footprint of cheese.
To reduce the environmental impact of cheese consumption, individuals can make conscious choices. Lower-fat cheeses tend to have a lower environmental impact because they require less milk, and the removal of fat from the cheese-making process reduces the climate impact. Additionally, choosing local cheeses with shorter transportation distances and supporting sustainable and organic farming practices can help minimise the environmental footprint of cheese production.
Some sustainable cheese brands focus on eco-friendly packaging, using recyclable materials and minimising waste. They also implement energy-efficient practices, such as utilising renewable energy sources and reducing processing and refrigeration requirements, to lower their carbon footprint. By selecting these sustainable options, consumers can make more environmentally conscious choices while still enjoying cheese as part of their diet.

Greenhouse gas emissions
Cheese is not good for the environment. According to the BBC's climate change food calculator, which uses data from a 2018 Oxford University study, eating 30 grams of cheese (enough to cover two crackers) three to five times a week for a year would generate approximately 201 kg of greenhouse gas emissions. This is equivalent to driving a car for 514 miles or heating an average UK home for 31 days.
The environmental impact of cheese is due to several factors. Firstly, cheese is a dairy product, and dairy cattle have a significant impact on the planet. Cattle produce methane and carbon dioxide, which have damaging effects on the planet. In addition, dairy farming is a major source of nitrous oxide, a greenhouse gas with a global warming potential 265-298 times greater than carbon dioxide. Agriculture generates 4.5 million tonnes of nitrous oxide per year through livestock manure, fertilized soils, and fertilizer runoff and leaching.
Another factor is the feed that cows consume. Grains such as corn and alfalfa are often fed to dairy cows, and the production and transportation of these grains have associated environmental costs. Additionally, the water and land required for dairy farming contribute to cheese's environmental impact. Dairy farms use approximately 83% of the world's farmland, and cheese production requires a substantial amount of water.
However, there are ways to make cheese consumption more sustainable. Choosing lower-fat cheeses is one option, as they tend to have a lower environmental impact. Skim mozzarella, gouda, and cottage cheese are examples of lower-fat cheeses. Additionally, supporting local and small-scale cheese producers can reduce the carbon footprint associated with transportation. Exploring cheeses made from alternative milk sources, such as sheep, goat, or buffalo milk, can also reduce environmental impact, as these options often require fewer resources.

Land and water use
Cheese is not good for the environment. According to the BBC's climate change food calculator, eating 30 grams of cheese three to five times a week for a year would generate approximately 201 kg of greenhouse gas emissions. This is the equivalent of driving a car for 514 miles or heating an average UK home for 31 days. The same quantity of cheese consumption over a year also uses 47,259 liters of water, enough for 727 eight-minute showers, and 740 square miles of land, equal to the size of two tennis courts.
The environmental impact of cheese is linked to its source: cattle. Enteric fermentation occurs in the digestive system of ruminant animals, such as cattle, sheep, goats, buffalo, and camels. These animals have a "fore-stomach", also known as a rumen, where microbes break down the food and allow them to digest it. Methane is produced in the rumen as a byproduct of the digestion process. It is 21 times more potent than carbon dioxide on a 100-year timescale and 84 times more potent over a 20-year period. Cattle produce both methane and carbon dioxide, which have damaging effects on the planet. In addition, dairy farming is a major source of nitrous oxide, a greenhouse gas with a global warming potential 265-298 times greater than carbon dioxide. Agriculture generates 4.5 million tonnes of nitrous oxide per year through livestock manure, fertilized soils, and the runoff and leaching of fertilizers.
The environmental impact of cheese is also influenced by the cows' diets. Climate change can affect the nutritional value and sensory traits of cheese, such as taste, color, and texture. The grains used to feed cows, such as corn and alfalfa, also have a carbon footprint. Even grass-fed cows can have a significant environmental impact, as they belch out a lot of methane. The environmental impact of cheese production can be reduced by supporting local and small-scale cheese producers, as this reduces the carbon footprint associated with long-distance transportation. It is also beneficial to look for cheeses with organic or grass-fed certifications, indicating environmentally friendly practices, and to explore cheeses made from alternative milk sources such as sheep, goat, or buffalo milk, which often require fewer resources and have a lower environmental impact.

Sustainable cheese
Cheese is a beloved food for many, but it is not without its environmental consequences. The cheese industry produces 145 million tons of whey annually, yet only 54% is reused. Cheese production also contributes to deforestation, wildlife displacement, and ecosystem disruption. Greenhouse gas emissions, particularly methane, are another concern.
However, this does not mean that cheese cannot be enjoyed sustainably. Here are some ways to make cheese consumption more environmentally friendly:
Choose Lower-Fat Cheeses
According to the Environmental Working Group (EWG), lower-fat cheeses tend to have a lesser impact on the environment. This is because the removal of fat from the cheese-making process reduces the climate impact, and since toxins build up in fat, lower-fat cheeses are also better for health. Examples of lower-fat cheeses include skim mozzarella, gouda, and cottage cheese.
Support Sustainable and Organic Producers
Look for cheeses with organic or grass-fed certifications, which indicate environmentally friendly practices. These certifications ensure that the cheese comes from sources committed to ethical and sustainable farming methods. For instance, Daylesford Organic is a brand known for its commitment to sustainable and organic farming, prioritising animal welfare and the treatment of their cows.
Buy Local and Small-Scale
Supporting local and small-scale cheese producers can also be a more sustainable choice. Transporting animals, milk, and cheese to broad, often international markets, contributes to the environmental footprint of cheese. Additionally, well-managed, grass-fed systems generate fewer environmental impacts and are more ethical and nutritious.
Reduce Waste
Having a sustainable mindset can also help reduce waste and overspending. Properly storing and using leftovers protects investments and generates goodwill towards the planet. Additionally, consumers can be mindful of realistic quantities to avoid waste.
Consider Alternative Dairy Sources
Cheeses made from sheep or goat's milk can also lower your environmental footprint. However, it is important to note that while goat cheeses are similar to cow cheeses in emissions, sheep cheeses are worse due to higher methane emissions per unit of milk produced.
By adopting these practices, cheese lovers can continue to enjoy their favourite dairy product while also contributing to a greener and more sustainable future.

Cheese consumption and health
Cheese is a widely consumed dairy product, but its impact on the environment has been a cause for concern. While the environmental effects of cheese production and consumption are significant, it is also important to consider its nutritional value and health implications.
Cheese is a good source of protein and calcium, which are essential for maintaining strong bones and muscles. It also contains other important nutrients like vitamin B12, phosphorus, and zinc. However, cheese is high in saturated fat and calories, which can lead to health issues if consumed in excess. The Environmental Working Group's "Meat Eater's Guide to Climate Change and Health" highlights the impact of cheese consumption on health and the environment.
The report found that cheese is the third-worst offender, after lamb and beef, in terms of climate impact. This is due to the significant greenhouse gas emissions associated with cheese production, mainly methane and nitrous oxide. Methane is produced during the digestive process of ruminant animals, such as cows, and is much more potent than carbon dioxide. Nitrous oxide, emitted during dairy farming, has a global warming potential hundreds of times greater than carbon dioxide. Additionally, cheese production requires large amounts of water and land, contributing to environmental concerns.
To make more sustainable and healthier choices, consumers can opt for lower-fat cheeses, such as skim mozzarella, gouda, and cottage cheese, which have a reduced environmental impact and are better for health. Toxins tend to build up in fat, so lower-fat options are generally healthier. Additionally, supporting local and small-scale cheese producers, as well as exploring cheeses made from alternative milk sources like sheep, goat, or buffalo milk, can reduce environmental impacts. Organic and grass-fed certifications also indicate sustainable farming methods.
While cheese consumption has its environmental and health considerations, making conscious choices and opting for sustainable and lower-fat options can help mitigate these impacts.
