You don’t have to be perfect to make a difference.

A study at the University of Michigan and Tulane University discovered that the single most important action we can take to combat climate change is to adopt a plant-based diet. It doesn’t have to be all or nothing. If we all decreased our animal protein intake by even 40-50% we could make significant progress in reversing climate change.


Animal agriculture is responsible for more than 18% of greenhouse gases worldwide. Plus, it contributes to land and water degradation, biodiversity loss, acid rain, coral reef degeneration and deforestation. Learn more about this on our plant-based Call to Action page by clicking here.

FACT: Just 1 family meal that contains 1 pound of beef needs up to 8,000 gallons of water to produce. YOUR ACTIONS MATTER.

How you can help?

Being 100% vegan has been an unattainable challenge for many people so let’s focus on being “imperfectly vegan” and taking the pressure off. Our team here at Habits of Waste translated the University of Michigan & Tulane University study into tangible action. If we all swapped 8 meals per week to plant-based then collectively we can do more than a few of us going fully vegan.

Climate change is now at an ‘all hands on deck’ urgency.

We can not wait for governments and corporations to act. Perhaps the single greatest contribution we can make as individuals is to change our diet. The carbon footprint reduction of committing to at least 8 plant-based meals a week is on par with switching to a hybrid automobile for the average American family.

— Dr. Martin Heller, Research Specialist, Center for Sustainable Systems, University of Michigan

Let’s do the math:

It is estimated that a 40% reduction in animal-based foods (8 meals / week) results in a ~504 kg CO2eq/person/yr reduction.

Average annual milage for a family of four =11484 mi/yr, at avg fuel efficiency (22.3mi/gal) and 8.887kg CO2e/gallon = 4577 kg CO2eq/yr

The same mileage with a Prius fuel efficiency of 55mpg = 1855 kg CO2eq/yr, so reduction is 2722 kg CO2eq/yr.

The conclusion: a family of 4 reducing diet by 504 kgCO2eq/person/yr = 2016 kg CO2eq/yr

Scientists recommend we cut our animal protein intake by at least 40% in order to protect the planet. 🌎 That’s 8 meals a week. Who’s in? I’m joining @howchangers to be #imperfectlyvegan through their campaign called #8meals

We asked how #8meals was working out and here’s what we heard back:

“I found it re-invigorating for my cooking! I have gotten tired of the endlessness of planning and preparing meals… but this lit a happy healthy fire under my butt. And I do love a challenge. Excited for a delicious week! And I like the idea very much that all meat need not be eliminated. Just less.
Thank you!”

“This is so doable !”

– Dahlia

“I could never go fully vegan but this I can do!”
