By comparing transit to personal automobiles on a CO₂ per mile basis, riding the bus once is equivalent to taking 3.5 cars off the road for that trip (much more than the one car you wouldn't be driving yourself)

Burning a gallon of gas emits 9 kilograms of CO₂, so if you use 20 gallons of gas in a month, you would emit 180 kilograms of CO₂. If you used ten fewer gallons per month, it would have the same impact as 1/10 of an acre of forest.

If you stopped driving and biked/walked, you would have the same impact as 1/4 acre of forest for a year.

The average amount of water a toilet uses per flush is 5 to 7 gallons which is the same as keeping one person hydrated for about 6 days.

The average use of showers is 1,971.7 gallons in a week. this is equal to 17 pounds of co2, and that adds up to be 70 pounds of co2 in a month and that is 212 pounds of carbon dioxide in a year

Eating 4 eggs a day instead of 10 slices of cheese for a year is the same as taking a car off the road for 3 months.

The average American family will waste approximately 20 pounds of food per month. This is enough food to feed approximately 16 people.

The FDA estimates that 30-40% of all food in the US goes uneaten. That can be up to 20 pounds of food waste monthly for the average American. This means Americans are throwing out the equivalent of $165 billion yearly as a nation.

Meat-rich diets, (100g or more), can produce 7.2kg of carbon emissions on average, just daily, which is about twice as much as a vegetarian or pescetarian diet. That produces about 3.8kg of carbon emissions daily.

In 2019, the average annual electricity consumption for a U.S. residential utility customer was 10,649 kilowatt-hours, an average of about 877 (kWh) per month. This would be the same as a professional cyclist biking at full speed for 243.6 days for 12 hours each day.

The average 2,000 sq. ft. U.S. home uses around 12,000 kilowatt-hours of electricity yearly. This is equal to about 18,739 pounds of carbon dioxide.
