Calculator and Comparison Facts

In 2015, MorningStar Farms® worked with Quantis, leaders in life cycle assessment consulting, to conduct a study comparing the environmental impact of veggie meals, meat-containing meals, and some of our own products across water use, greenhouse gas emission and land use. With that data we created the Veg Effect Calculator so that everyone can see the good their veggie meal can create.

Choose the number of meals with meat you'd swap for veggie meals each week.
Now, imagine what could happen if more people made this swap. What a difference we could make!

That's enough water for 201 average showers image
That’s enough water for 201 average showers. Lather, veg, repeat.
Oh dear. If that many people chose veggies that often, it would literally change agriculture as we know it, so we can’t calculate what the impact would be. But hey, way to be optimistic!

*The actual environmental impacts will vary depending on various factors, including the source of the food and other overall dietary choices. Click here for lifecycle assessment and see below for comparison facts.

Choosing veggie meals over meals with meat can result in some big time resource savings. To make those savings more relatable, we’ve equated them to things you might recognize, like a parking space, or Niagara Falls or the moon. To find out how we define these comparisons, see the links below.


We based our Life Cycle Assessment on data from adults 18+ only, so all of our impact data reflects only the adults of a given population. Here’s how we got to those adult population numbers.

2014 estimated population figure from the Census Bureau image
U.S. - 245,201,076.

We used the 2014 estimated population figure from the Census Bureau and subtracted their 23.1% under 18 estimated population.

We averaged the 18 plus populations from each US state provided by the Census image
Average State - 4,770,175.

We averaged the 18+ populations from each US state provided by the Census.

We averaged the populations of every US city with over 50,000 residents image
Average City - 124,839.

We averaged the populations of every US city with over 50,000 residents and then subtracted the nationwide under 18 ratio of 23.1%.

To the Moon and Back image
To the Moon and Back

The distance traveled in a trip "to the moon and back" is equal to twice the distance of the moon from the earth (238,800 miles), plus one half the circumference of the moon (6,784 miles) - 484,384 miles. This is because a space craft would generally rely on the gravity of the moon to sling shot it back to Earth.

Universe Today makes mention of the longest and smallest distances from the Earth to Mars. We're using the closest expected approach with Mars in 2016, at 46.8 million miles.
