How to Reduce Your Carbon Footprint By Eating Bugs

Why Eating Bugs Reduces Your Carbon Footprint

Eating bugs instead of meat can significantly reduce your carbon footprint. This is because insects have a much lower environmental impact than traditional livestock.

Here are some of the main reasons why eating bugs is better for the planet:

  • Bugs need less feed and water. Crickets, for example, need 12 times less feed than cattle to produce the same amount of protein. They also require significantly less water. This reduces land and water use.

  • Bugs generate less greenhouse gases. The production of beef releases up to 105 kg of CO2 per kg. Crickets emit just 1 kg of CO2 per kg. The lower emissions are linked to the reduced feed, water and land requirements.

  • Bugs need less space. Cattle grazing and feed crop production take up an estimated 70% of agricultural land. Bugs can be produced in compact facilities, freeing up land for other uses like carbon capture.

  • Bugs have higher feed conversion efficiency. Crickets need 6 times less feed than cattle, and half as much as pigs and chickens, to produce the same amount of protein. Less feed means lower environmental impact.

So by switching from meat to insect-based protein sources, you can significantly reduce the carbon footprint of your diet. Even small increases in bug consumption can make a difference.

How Much of a Difference Do Bugs Make?

Studies have quantified the actual carbon footprint reduction when replacing meat with bugs in your diet:

  • Replacing beef with crickets can reduce the carbon footprint of your protein intake by up to 98%.

  • Swapping beef for mealworms can reduce the carbon footprint by 96%.

  • Switching from beef to locusts lowers the carbon footprint by 93%.

So going from a beef-heavy diet to one focused on insects can almost completely decarbonize your protein consumption.

Even incorporating a modest amount of bugs, such as 25% of total protein, can cut your diet’s carbon footprint by around 25%. Any step towards eating more bugs will make a positive environmental difference.

Easy Ways to Start Eating More Bugs

Here are some simple tips to start integrating bugs into your diet:

  • Try cricket protein powder in smoothies or baking. It has a mild, nutty flavor.

  • Use granola with roasted crickets as a crunchy topping for yogurt or oatmeal.

  • Make burgers and meatballs with a mix of beef and chopped crickets.

  • Add whole or powdered crickets when making tacos, chili or stir-fries.

  • Roast crickets with spices as a high-protein snack.

  • Use mealworms and locusts as fishing bait, then eat what you catch!

  • Top pizzas with roasted crickets for extra crunch.

  • Make trail mixes with roasted crickets, nuts, seeds and dried fruit.

Start slowly, focusing on recipes that disguise bugs or use them as minor ingredients. Over time you can increase the proportion as your taste for them develops.

Answering Common Concerns About Eating Bugs

Many people new to entomophagy (eating insects) have some common concerns. Here are answers to some frequent questions:

Are bugs safe to eat?

Yes, most edible insect species are perfectly safe if farmed or wild-collected properly. People around the world have eaten insects for millennia.

Aren’t bugs dirty/unsanitary?

Farmed bugs are produced under controlled conditions to eliminate contamination and are very clean. Cooking them kills any potential germs.

Don’t bugs carry diseases?

There are no documented cases of diseases spreading to humans from farmed insects. Proper farming practices minimize any disease risks.

Will I have an allergic reaction?

Allergies are possible, but insect allergies are rare. You should still take precautions when trying them for the first time.

Will bugs taste bad?

Most people are pleasantly surprised by the taste when trying insects! Bugs tend to take on the flavors they are cooked with.

Isn’t it weird to eat bugs?

It may seem unusual, but keep in mind that 2 billion people around the world regularly eat insects! They are a completely normal food in many cultures.

Will I still get enough protein?

Yes, many bugs like crickets and mealworms are great sources of protein, comparable to meat and fish.

So don’t let fear of the unknown stop you from trying out eco-friendly bug eating. An open mind can lead to great new culinary experiences!


Switching even a small portion of your diet from meat to insects can massively decrease your carbon footprint. Bugs require far fewer resources to produce than beef and generate a fraction of the greenhouse gases.

Crickets, mealworms, locusts and other edible insects can easily be incorporated into many recipes. Start slowly, learning to enjoy their nutty flavor. With an open mindset, you may come to appreciate bugs for their sustainability and nutrition in addition to their taste.

Adopting entomophagy, even to a limited degree, is one impactful way we can alter our eating habits to reduce environmental harm. Given the enormous carbon footprint of livestock production, opting for eco-friendly bugs is an important strategy for lowering our individual contributions to climate change.
