We currently only calculate the cumulative impact for VEGETARIANISM pledges.

Individuals: 1 | Days: 1 | Greenhouse Gas: 9 lbs | Grains: 3.36 lbs | Water: 525 gal

The Formula:
Over the course of a year, a person's vegetarian diet can help reduce 1.5 tons of CO2. (source: csmonitor.com)
1.5 tons = 1500 kg = 3,300 lbs
3,300 lbs / 365 days = 9 lbs CO2 per day ***

An average US person consumes 3.4 ounce (0.21 lb) of beef a day
(source: CattleNetwork.com)
Producing 1 lb of beef requires 2,500 gallons of water and 16 lbs of grain.
2,500 gal * 0.21 lb = 525 gal Water per day ***
16 lbs * 0.21 lb = 3.36 lbs Grains per day ***
