“it takes about 2400 liters of water to make a burger” warns the Alec

Recently, members of the local energy and climate agency (Alec) in Lyon unveiled an instructive study on burgers. And more particularly on the resources necessary to manufacture them. Finding precise answers doesn’t seem so simple, since these change depending on what ingredients you choose inside your sandwich.

The carbon impact of a beef burger is therefore 14 times higher than that of a vegetarian burger. explains the Alec without however specifying the origin of the figures. For those who eat veggie burgers once a month, “that works out to about one beef burger and 4 chicken burgers” for a year explains the “service of the Lyon metropolitan area and actors working for the energy transition”.

We also learn that the water needs are heavy to make Whoopers, Big Macs or even Marcel Jackson.

For a burger with meat, you need about 2,400 liters of water. For comparison, it is a little less than for the manufacture of a t-shirt, with approximately 2,700 litres, but generally a t-shirt is used more than once, which makes it a better investment”. The Alec then quotes the Water FootPrint Network which states that an omnivore “who would replace 50% of animal products in their diet with plants could reduce their water footprint by 30%”.

It remains to be seen whether consumers are ready to change their eating habits in an attempt to limit their impact on the planet.
