Method

Where the numbers come from.

The emissions and land figures come from Poore & Nemecek's 2018 meta-analysis in Science, still the largest study of food's environmental footprint: 38,700 farms across 119 countries. It found that moving to a diet without meat and dairy cuts an individual's food emissions by up to 73% and their farmland use by roughly 76%.

Water savings draw on Mekonnen & Hoekstra's water-footprint work, which accounts for the irrigation and feed-crop water embedded in animal products — the reason a kilo of beef carries thousands of litres while a kilo of lentils carries a fraction of that.

Animal counts follow Counting Animals' widely cited method, which includes farmed fish and shellfish. Because aquatic animals are killed in vast numbers relative to their size, they make up most of the total, and any estimate that excludes them dramatically understates the toll.

Every figure here is an upper-bound average for one person in a high-consumption country. Treat it as a scale, not a receipt: the useful insight is that a single year of ordinary meals moves numbers that most people assume only policy can move.

FAQ

Questions, answered.

How many animals does going vegan save per year?
Counting a full year at roughly one animal per day — including farmed fish and other aquatic animals, which dominate the count by number — the usual estimate is around 365 lives, of which the large majority are fish and shellfish. Land animals alone come to roughly 25–30 per person per year.
How much water and CO₂ does a plant-based diet save?
Poore & Nemecek's 2018 analysis of 38,700 farms in 119 countries found that avoiding meat and dairy cuts an individual's food-related emissions by up to 73% — around 9 kg CO₂e a day for a typical Western eater — and frees up about 8.5 m² of farmland per day. Water footprint work by Mekonnen & Hoekstra puts the freshwater saving near 4,000 litres a day.
Are these numbers exact?
No. They are upper-bound population averages, not a measurement of your kitchen. Your real figures depend on where you live, what you replaced, and how your food was produced. The dashboard is designed to show the order of magnitude, which is the part that matters.
Does the dashboard store my data?
Everything is kept in your own browser using local storage. Nothing is sent to a server, there is no account, and clearing your browser data resets the dashboard.
What if I was already vegetarian or flexitarian?
Pick that starting point and the totals scale down accordingly — a vegetarian switching to fully plant-based saves roughly a third of what a daily meat eater does, because dairy and eggs still carry a significant footprint.
