The Broke Environmentalist's Guide to Ethical Grocery Shopping

When we investigated big box grocery stores, we found that most of the major U.S. chains have very low sustainability ratings, which left us wondering — how do you grocery shop more sustainably while sticking to a budget?

‍

While food prices are up 19% since 2022, the good news is that ethical grocery shopping doesn’t have to be expensive, and you don’t have to split up your shop across a bunch of places to make it work. Often, you can stick to your values and stay within your budget. Here are a few simple, practical ways to do sustainable grocery shopping on a budget.

Things to Do Before Making Your Grocery List

‍

Saving money while sticking to your values starts before you even make your grocery list. First, shop your fridge and pantry to see what you already have. Then plan meals around those items, filling in only what you need. This saves time and money, reduces food waste, and can lower your grocery bill. Here are some guides to help you get started:

Choose Cheaper Proteins

‍

Plant-based protein sources like legumes, lentils, and dried beans are affordable, protein-dense, and have a smaller environmental footprint than meat. Buying them in bulk can lower costs and reduce packaging waste. If replacing meat entirely isn’t realistic, try cutting back and swapping in options like tofu and beans.

Shop From Surplus Inventory and Clearance Goods

‍

Discount grocers like Martie can help you shop more sustainably while cutting your grocery bill. The marketplace partners with brands to sell overstocked items, products with outdated packaging, or seasonal goods. It’s food that’s still perfectly edible but often discarded for cosmetic reasons. You can have these items delivered to your door at up to 80% off, while also keeping food out of landfills and reducing waste, water use, and CO2 emissions.

‍

You can also look for “clearance” or “ugly produce” sections at standard supermarkets, which often offer steep discounts. Apps like Flashfood can help you find soon-to-expire meat, produce, and bakery items from major grocery chains at around half price.

Support Local Farmers' Markets

‍

Local farmers’ markets are a great option for sustainable shopping on a budget. They offer a diverse range of fresh, seasonal produce while also supporting local farmers and producers. Local, in-season produce is typically cheaper and healthier than out-of-season options, and it often has better flavor and nutrients.

‍

Most farmers’ markets accept SNAP benefits, and programs like Double Up Food Bucks can help you stretch your grocery budget even further. Here are some guides to help you navigate farmers’ markets on a budget:

‍

Buy Non-Perishable Items in Bulk

‍

Warehouse clubs like Costco and Sam’s Club can help you save money on bulk purchases if you shop strategically. Larger pack sizes often mean a lower per-unit price, but they aren’t a fit for everyone. They tend to work best if your household goes through groceries, snacks, and household supplies quickly, you have space to store extras (like a large pantry, an extra freezer, or a garage), or you meal prep in large batches. If that sounds like you, consider buying staples like rice, lentils, oils, spices, frozen produce, and baking essentials in bulk.

‍

When buying bulk at refill stores, other local farm shops, or stores like Sprouts, you can take your own reusable containers or packets. This will help you cut down the packaging waste.

‍

Look for Trusted Certifications

‍

Some brands lean on nature imagery, leafy logos, and words like “natural” to appear more sustainable or ethical than they really are. These greenwashing tactics can lead you to pay more for claims that aren’t backed by anything. So skip the marketing and check for third-party certifications tied to the values that matter most to you. Pick the one or two criteria you care about, learn what their seals look like, and look for those labels. Here are some trusted certifications to look for:

‍

• Organic: USDA Organic verifies that produce and ingredients are grown without synthetic pesticides or fertilizers.
• Fair labor and trade: Fair Trade Certified and Fairtrade International signal fairer wages and working conditions for farmers and workers.
• Cruelty-free and animal welfare: Leaping Bunny confirms no animal testing, and they are certified cruelty-free.
• Non-GMO: Non-GMO Project Verified flags foods made without genetically modified ingredients.
• Sustainable seafood: The blue Marine Stewardship Council (MSC) label marks wild-caught fish from fisheries managed for the long term.
• Responsible sourcing: The Rainforest Alliance frog seal covers items like coffee, tea, and chocolate grown ethically.

Grow Your Own Produce If You Can

‍

Growing your own food is a great way to reconnect with the planet and the cycles of life. It can also help you save money. The average garden yields $600 of produce per year and costs around $70 to start. And you don’t need an elaborate kitchen garden. If you have the space, time, and energy, you can start by growing vegetables and herbs in a container or pot on your patio or balcony.
