Find out how much water you save by eating plant-based. Enter how long you've been on a plant-based diet (or plan to be) along with your current diet type, and see your total water savings in gallons, plus reductions in CO₂ emissions, land use, and grain consumption — all broken down by day, month, and year.

A fully vegan diet saves approximately 1,100 gallons (4,164 litres) of water per person per day compared to a standard omnivore diet. This figure comes from the water required to raise livestock, grow their feed, and process animal products. Beef alone requires around 1,800 gallons per pound.
Producing animal protein requires water at multiple stages: growing the grain and grass animals eat, providing drinking water for livestock, and processing meat at facilities. It takes roughly 7 lbs of grain — and all the water to grow it — to produce just 1 lb of beef, making animal agriculture extraordinarily water-intensive compared to growing plants directly for human consumption.
A vegan diet (no animal products whatsoever) generates the largest water savings since it eliminates dairy and eggs in addition to meat. Dairy products like cheese and milk also carry significant water footprints — cheese requires about 382 gallons per pound. A vegetarian diet still saves substantial water by eliminating meat but saves somewhat less than full veganism.
Yes — even reducing meat consumption significantly lowers your water footprint. A Mediterranean diet, which emphasises plants and fish while limiting red meat, can save hundreds of gallons per day. Every meal where you swap meat for beans, lentils, or vegetables contributes real water savings, even if you haven't gone fully plant-based.
Livestock farming accounts for roughly 14.5% of global greenhouse gas emissions according to the FAO. A vegan diet is estimated to cut an individual's food-related carbon footprint by approximately 20 lbs (9 kg) of CO₂ equivalent per day. This calculator uses per-day savings rates scaled to your chosen diet type and the total number of days.
Animal agriculture uses roughly 77% of global farmland while providing only 18% of global calories. 'Land preserved' reflects the square footage (or square metres) of forest and farmland that is spared from conversion or degradation when you don't consume animal products. Vegan diets save approximately 30 sq ft of forested land per day.
On average, a vegan diet spares approximately one animal life per day when accounting for land animals, poultry, and aquatic animals across the full supply chain. This is an approximation based on per-capita consumption data and slaughter statistics, and the actual figure varies by region and specific dietary choices.
The daily savings rates used in this calculator are based on widely cited research and data from sources including Cowspiracy, the UN FAO, and peer-reviewed studies on dietary water footprints. Exact figures can vary depending on geography, farming practices, and individual consumption habits, but the figures here represent well-established averages used by environmental researchers.
