Have you ever considered how much water it takes to make jeans, a t shirt, beef, or other items we use or consume in society on an everyday basis?
In this guide, we look at how much water is takes to make and produce common everyday products and foods i.e. what their water footprints are.
Although water footprints of products and foods are a very rough/general estimate only, they can be a good starting point to consider how the choices we make of what to produce and consume impact water resources.
Summary – Foods, Products, & The Water It Takes To Make Them
- On a per weight basis, livestock animals meats, dairy based products (such as chocolate, butter and cheese) and processed foods can be water intensive to produce
- Amongst livestock animals meats, poultry tends to take less water to produce than other meats like beef and lamb, or even pork for example. Beef tends to be be the most water intensive (largely from animal feed for factory farmed beef)
- In terms of non animal meat based foods, some rice paddy varieties, some olive varieties, and some almonds can be water hungry
- Tomatoes and cabbages might be amongst some of the least water intensive crops to grow, along with potatoes
- With food, it’s too simplistic to give one figure that summarises the amount of water required to produce it. One things you have to consider how water use is being measured.
- For example, different measurables might include water usage per serving size, per gram of protein, per gram of fat, per amount of carbs, per micro and macro nutrients, per calorie, price, and so on. Some estimates indicate that meat even uses less water compared to fruit, grains and vegetables when measuring per dollar of economic value produced
- In addition, some foods have different variations and types – like sugar – which can be produced from sugar beet or sugar cane, and both these variations can have different water footprints. Milk is another example – there’s many different types of milk available – cow milk, goat milk, almond milk, and so on
- Water required to grow or produce food can also be geographic location specific i.e. it can depend on the methods or systems the farmer or producer uses, the soil type, the local climate, the amount of rain fed water used vs other types of water, and so on. These variables can drastically change the final water volume required for production
- Something that people don’t consider with beverages like sodas, fruit juices, coffee and beer or wine is that it can be the crops or plants used in those beverages, and not the manufacturing process that can be responsible for a lot of water use. Pure water usually has a lower water footprint than all those beverages
- Separate to the water footprint of individual foods and drinks, is the water footprint of a person’s diet. This takes into consideration the amount and types of foods eaten. For example, the average American diet might be far more water intensive than the diet of someone from another country
- Also separate to the water footprint of individual foods and drinks, is the volume of water used for certain food products within the agriculture industry as a whole. Volume can be broken down into plant vs non plant based products, and then into the individual meat types, fruit types, vegetable types, grain types, and so on. One estimate from news.thomasnet.com is ’29 percent of the total water footprint of the agricultural sector in the world is related to the production of animal products. One-third of that water is used to raise beef cattle.’
- In terms of fibres, cotton usually requires a lot more water to grow compared to other fibres
- Cars as a product usually use a lot of water to manufacture
- Different types of energy or electricity production can be more or less water efficient than others – for example, natural gas can be far more water efficient per unit of electricity or energy produced than coal and some types of biofuel
- With any product, it should be considered how long that product lasts for – and the water footprint can be divided among the number of years. This gives an idea of water footprint per year of owning the product (and gives a good way to compare products too). This is also a good way, if you throw out or update products regularly (like cars and phones), to see what your water footprint is to repair or keep a product vs getting a new one
- Direct and indirect water used to produce a product should be considered – this provides a total water footprint for the product across the entire production process, right up to purchase and consumption. For example, a product like water needs to be packaged, usually with a plastic bottle, and then also disposed of – both of which have a water footprint. Operational water footprints should also be considered e.g. how much water is used in the products and services required to run, repair and maintain … cars are a good example of this with water required to refine fuel, to clean the car, and so on.
- The features and characteristics of a finished product should be considered. As one example, 1kg of bovine leather may require a certain amount of water to produce, but the final amount of leather used in a small leather wallet is far less than the amount of leather used in a large leather jacket – and this impacts the final water footprint.
- The type of water used to produce a product or grow food should be considered – for example, using highly renewable water or growing rainfed crops, is different to using non renewable fresh water, or excessive water use from sources such as aquifers that can take a long time to recharge
- When looking at the visible and invisible water footprint of individuals, we see that the food we eat makes up a large majority of the total footprint, with meat eaters having a larger water footprint than vegetarians. Food waste also play a significant part in the daily water footprint of an individual
- There’s ultimately a vast amount of variables that can go into calculating and comparing water footprints – which can make the task complex
- Water footprints also have their limitations, such as only producing a water volume number that represents product. Local context such as providing jobs and livelihoods to people, or having abundant water supplies are represented with a basic water footprint number
*Note – water footprints of different products and activities are a rough guide only because of the nature of being able to accurately gather water use data over the lifecycle of a product, and the complexities and challenges involved. They can however be used to identify general trends and general water data, as well as be used for general comparisons.

- The global average water footprint of chicken meat is about 4330 litre/kg. The water footprint of chicken meat is smaller than the footprints of meat from beef cattle (15400 litre/kg), sheep (10400 litre/kg), pig (6000 litre/kg) or goat (5500 litre/kg).
- The water footprint related to the animal feed takes by far the largest share (99%) in the total water footprint of beef. Drinking and service water contribute only 1% toward the total water footprint. One piece of beef can be very different from another piece. The precise water footprint of beef strongly depends on the production system from which the beef is derived (grazing, mixed or industrial), the composition of the feed and the origin of the feed. Due to the large feed conversion efficiency, beef from industrial systems generally has a lower total water footprint than beef from mixed or grazing systems.
- The water footprint of sheep meat strongly depends on the production system from which the meat is derived (grazing, mixed or industrial), the composition of the feed and the origin of the feed.
- The average water footprint per calorie for pork is five times larger than for cereals and starchy roots. The average water footprint per gram of protein in the case of pork is three times larger than for pulses.

- The production of one kilogramme of beef requires approximately 15 thousand litres of water (93% green, 4% blue, 3% grey water footprint). There is a huge variation around this global average. The precise footprint of a piece of beef depends on factors such as the type of production system and the composition and origin of the feed of the cow.
- The water footprint of a 150-gramme soy burger produced in the Netherlands is about 160 litres. A beef burger from the same country costs on average about 1000 litres.

- Biodiesel isn’t quite so green in the context of water consumption. More than 180,000 liters of water are required to produce enough soybean-based biodiesel to provide a home with a month’s worth of energy. This is because large amounts of water are required for irrigation of the soil in which the soybeans grow, then more water to turn the soybeans into biofuel.
