How to Reduce Your Carbon Footprint By Simply Changing Your Diet

Reduce or Eliminate Meat Consumption

Eating meat, especially beef and lamb, has a significant carbon footprint. Ruminant livestock like cattle produce methane, a potent greenhouse gas. Their feed also requires land and water resources.

I have made efforts to cut down on the amount of meat I eat or even eliminate it from my diet completely. Some simple ways I’ve done this include:

  • Going meatless on certain days of the week, like “Meatless Mondays.” This reduces my meat intake without completely eliminating it.

  • Choosing plant-based protein sources like beans, lentils, and tofu more often instead of meat. These are lower carbon options.

  • Opting for chicken and pork over beef and lamb when I do eat meat. Their production emits less greenhouse gases.

  • Exploring vegetarian recipes to find new tasty ways to avoid meat. Things like veggie burgers, pasta dishes, and curries can satisfy without meat.

Over time, I’ve found cutting down on meat reduces my carbon footprint significantly while still letting me enjoy some meat-based dishes occasionally.

Eat More Plant-Based Foods

In general, choosing plant-based foods over animal products reduces carbon emissions from food production. Here are some simple diet changes I’ve made:

  • Eating more fruits and vegetables. Produce has a very low carbon footprint. I try to eat seasonal, local produce when possible.

  • Choosing milk alternatives. I’ve switched from dairy milk to unsweetened almond milk or oat milk. Their production emits less greenhouse gases.

  • Having meatless days. I designate certain days of the week to eat completely plant-based. It’s an easy way to add more veggies and legumes into my diet.

  • Replacing eggs with tofu or beans. Scrambled tofu makes a great substitute for scrambled eggs in the morning. Beans also work well in dishes like burritos.

  • Exploring whole grains. There are lots of climate-friendly whole grains like quinoa, barley, and farro to try in place of refined grains.

These simple substitutions add up! I’ve found going plant-based even a few days a week makes a meaningful difference.

Shop Locally and Seasonally

Eating local, seasonal produce has a lower carbon footprint than imported foods. Some tips:

  • I shop at farmer’s markets when possible to buy fresh, local fruits and vegetables. This supports local agriculture too.

  • I look for in-season produce when meal planning. Things like berries in the summer or squash in the fall.

  • If shopping at a grocery store, I check where produce is sourced from and aim to buy local.

  • I purchase foods that can be grown locally like apples or carrots rather than importing out of season foods.

  • I am mindful of air-miles – produce flown in has higher emissions. I try to avoid imported produce when local is available.

  • I freeze in-season produce to enjoy later in the year. This reduces the need to import.

Choosing local, seasonal food reduces emissions from long distance transport and refrigeration. Supporting local farmers and produce has great environmental benefits too!

Waste Less Food

Reducing food waste is another way I lower my diet’s carbon footprint. Some helpful strategies include:

  • Planning meals ahead of time so I only buy what I need at the store. This prevents over-purchasing.

  • Storing produce properly to maximize freshness. I keep things like bananas and tomatoes out on the counter.

  • Checking expiration dates and using the “FIFO” method (first in, first out) to rotate food in my fridge and pantry.

  • Freezing extra portions of cooked foods to eat later in the week. Soups, curries, and casseroles freeze well.

  • Using leftovers creatively, like turning leftover chicken into a salad or sandwich the next day.

  • Composting inedible food scraps rather than throwing them out. This keeps them out of landfills.

Avoiding food waste means I get the most out of what I purchase while reducing its environmental impact. A little planning goes a long way!

Drink Sustainably

Beverages can sneakily contribute to our carbon footprint. Here are some easy fixes:

  • I choose tap water whenever possible rather than bottled water. Tap water has no packaging waste.

  • When I buy drinks, I choose cans over plastic since aluminum is very recyclable.

  • I’ve switched to dairy-free milk options like oat or almond milk. Their production and transportation emits less CO2 than dairy milk.

  • I avoid juice and instead eat whole fruits. It takes a lot of fruit to make a little juice!

  • I make coffee and tea at home rather than getting take-out drinks. This prevents disposable cup waste.

  • If I do purchase drinks, I bring a reusable cup or bottle to avoid extras.

With some simple swaps, I’ve lightened the footprint of what I drink. Using reusable containers also reduces waste.


Adjusting my diet is an impactful yet simple way I reduce my carbon emissions. Eating less meat, choosing more plants, reducing waste, and drinking sustainably makes a tangible difference. With a few new habits, I can eat foods I love while also caring for the planet!
