The data that MeatWise uses is specified towards the Dutch meat industry and stems from major scientific research institutes to guarantee you that everything is a 100% valid and applicable. A summary is presented below in a table, but can also be seen on the buttons that are present on several locations! A more detailed deconstruction of the data is presented below along with the research institute that performed the research.

 Water Usage – Researched by UNESCO Insitute for Water Education

The green, blue and grey water usage should be added together to sketch a complete and holistic picture of the amount of water an animal uses. To convert the amount of water into something less abstract, the total number of hours of showering with the same amount of water is calculated. To calculate this a normal shower head was assumed to use 8.7 liters of water per minute.

For beef, pork, and poultry: See this link on page 27.

Example: In the Netherlands, one kilogram of beef uses on average 6513 liters of water which is equivalent to 12.5 hours of showering. Pork uses 4429 liters of water which is equivalent to 8.5 hours of showering. Lastly, poultry uses 1787 liters of water which is equivalent to 3.4 hours of showering.

For meat substitutes: See this link on page 18.

Example: A 150-gram soy burger uses 157.9 liters of water. A kilogram of soy burger hence uses 1052 liter which is equivalent to 2 hours of showering.

Feed conversion ratio – Research by Wageningen University

The feed conversion ratio indicates how much plant-based protein an animal has to consume in order to produce one kilogram of meat based protein. Since the meat substitute doesn’t need to convert plant-based protein into animal based protein this ratio is by definition 1:1.

For beef, pork, and poultry: see the link on page 12.

Example: To produce one kilogram of protein from beef a cow needs to eat 25.9 kilograms of plant-based protein. Hence the feed conversion ratio is 1:25.9.

Carbon Dioxide (CO2) Emissions – Researched by the Environmental Assesment Agency part of the Dutch Ministry of Infrastructure and the Environment

To convert the CO2 emissions into something less abstract we calculated the number of kilometers that can be driven with an average car. To calculate this we assume that an average car drives 15 km with 1 liter of petrol. One liter of petrol emits 2392 grams of CO2 hence an average car emits 160g of CO2 per kilometer.

For beef, pork, poultry, and meat substitutes: see this link.

Example: 100 grams of beef uses 1.8 kg carbon dioxide, hence a kilogram of beef uses 18 kg carbon dioxide. This is equivalent to 112.5 km of driving with an average car.
