California is known for its actions on environmental issues. Starting January 1, 2025, stores can only provide customers with shopping bags before checkout: recycled paper bags or compostable bags (for unpackaged items such as bulk food or bulk produce). Effectively banning the use of all single-use plastic takeout bags. This statewide plastic bag ban is an important step towards zero-waste living and reducing plastic pollution.
Whether you're a shopper, business owner, or just an average person who cares about the planet, this guide will help you understand the changes and what to expect in the future.
What Is California’s California Banning Plastic Bags?
California has had some plastic bag laws for a while. Back in 2016, voters passed Proposition 67, which banned single-use plastic bags at grocery stores and large retailers. But in 2025, the rules got tougher.
California's new plastic bag ban builds on earlier laws like SB270 and Proposition 67, expanding restrictions to nearly all types of retail plastic packaging — even banning some plastic bags that were once allowed, such as thicker "reusable" plastic bags and certain biodegradable plastic bags, including thick bags that were once labeled "reusable."
Now, stores must stop giving out any plastic bags unless they are certified compostable or reusable under strict standards.
Why Is California Banning Plastic Bags?
The goal is simple: less plastic pollution.
Plastic bags don’t break down easily. They end up in oceans, harm wildlife, and clog landfills. California wants to move toward a zero waste future, and banning plastic bags is a big step.
The goal of the California plastic bag law is to limit harmful plastic packaging waste, keep oceans clean, and move toward a plastic-free shopping culture.
What Kinds of Bags Are Banned?
- Single-use plastic bags (thin ones from grocery checkouts)
- “Biodegradable” plastic bags (unless certified compostable)
- Reusable plastic bags under 2.25 mil thickness
- Plastic bags at clothing stores, convenience stores, and more
Bags must now be either reusable shopping bags that meet California’s durability standards or BPI-certified compostable bags that break down safely in composting systems.
What Kinds of Bags Are Still Allowed?
Don’t worry — you won’t have to carry your groceries in your hands.
Here are some bag options that are still legal:
✅ Allowed Bags:
- Paper bags (may cost $0.10 or more)
- Reusable fabric bags (canvas, thick polyester, etc.)
- BPI-certified compostable bags
- Bring-your-own bags (any type you already own)
💡 Tip: Always carry a small foldable bag in your purse or car. You’ll be ready anytime you shop.
Who Will Be Most Affected by California Bans All Plastic Bags?
- Grocery stores
- Retail stores (clothing, electronics, hardware, etc.)
- Convenience stores
- Food delivery platforms
- Farmers markets
What If You Forget a Shopping Bag?
Many shoppers are adjusting to this grocery bag ban in California by keeping a foldable cloth bag with them, or buying low-cost eco-friendly bag alternatives at checkout.If you forget your shopping bag, you have a few choices:
- Buy a paper bag for around 10–25 cents
- Buy a reusable cloth bag at the checkout
- Carry your items by hand (some people do this!)
Stores are not allowed to give you a plastic bag, even if you ask — unless it’s compostable or meets specific reuse standards.
What About Trash Bags or Produce Bags?
- Plastic trash bags (kitchen, yard, bathroom use)
- Produce bags in the fruit and veggie section
- Plastic packaging for frozen or raw meat
However, lawmakers may look at these in future bans. Some cities in California already offer compostable options for trash bags and produce bags.
Are Compostable Bags Allowed?
Yes — but they must be certified compostable, like those with the BPI logo.
These bags are designed to break down in composting systems, not regular trash. They're often used in places with food scrap recycling or compost bins.
❗ Be careful: Some bags are labeled “biodegradable” but are not truly compostable. Always look for trusted labels.
What Happens If a Store Breaks the Rules?
Stores that give out banned bags can face:
- Fines
- Inspections
- Complaints from the public
Retailers are encouraged to educate staff and customers. Many already have signs posted near the register about the new rules.
If your favorite shop is still giving plastic bags, you can report it to local city officials or the CalRecycle department.
How Does This Affect Small Businesses?
Small businesses are also subject to this rule – but some may need more time to adapt.
- Provide paper or compostable shopping bags
- Encourage customers to bring their own shopping bags
- Sell branded reusable shopping bags as extra income
Small shops must also follow California’s plastic packaging rules, though some receive extra time to switch to compostable or reusable options.
Is the Plastic Bag Ban Only in California?
No. California isn't the only state to ban plastic bags. While California leads the way, states like New York, New Jersey, Oregon, and Hawaii have also passed plastic packaging bans. California's law is one of the most comprehensive in the U.S.Other states have similar laws, including:
- New York
- Oregon
- Hawaii
- New Jersey
- Vermont
Globally:

- The European Union has restrictions
- Chile, India, and Kenya have bans

- Support stores that care about sustainability
- Talk to friends and neighbors about the ban

FAQs:
Is California really banning all plastic bags in 2025?
Yes. In 2025, California expanded its state-wide plastic bag ban, enforcing one of the strongest plastic packaging prohibitions in the U.S. The new California bag law makes it illegal for most stores to offer single-use plastic carryout bags, even thicker “reusable” plastic ones that were previously allowed. This move supports the state’s zero-waste and sustainability goals.
Does California’s plastic bag law apply to all stores and businesses?
Most retailers and grocery stores must follow the updated CA plastic bag restrictions, including supermarkets, pharmacies, and clothing shops. Some small businesses and food vendors may have limited exceptions, but they are still encouraged to follow the plastic carryout bag ban and switch to eco-friendly alternatives like paper or certified compostable bags.
Biodegradable vs Compostable bags in California?
Under California’s sustainability laws, only BPI-certified compostable bags (meeting ASTM D6400 standards) are allowed under the new plastic bag policy. Bags labeled “biodegradable” are not permitted unless they are properly certified, as they don’t meet environmental requirements. This is part of California’s effort to promote plastic-free shopping and reduce greenwashing.
Can I still use plastic trash bags or produce bags in California?
Yes — for now. While plastic grocery bags are banned, plastic trash bags and produce section bags (like the ones in fruit and veggie aisles) are still allowed. However, some California cities are already considering new retail plastic packaging rules to phase these out as well.
Are paper bags free under California’s plastic bag ban?
No. As part of the California plastic bag law, stores must charge at least $0.10 for a paper shopping bag. This small fee encourages customers to bring their own reusable shopping bags and helps reduce dependence on disposable packaging. It’s another step toward supporting the state’s zero waste and plastic pollution reduction goals.
