Greenwashing in Packaging: 7 Red Flags Every Buyer Should Know

What Is Greenwashing in Packaging? 

Greenwashing is when companies market products as environmentally friendlywithout the substance to back it up. The term was coined in 1986 by environmentalist Jay Westerveld, who called out hotels promoting towel reuse to ”save the planet”—when they really just wanted to cut laundry costs.Today, greenwashing in packaging often involves vague terms like ”green,” ”eco- friendly,” ”bio-based,” and ”biodegradable” without evidence or certifications to support these claims. These deceptive practices mislead consumers, waste resources, and make it harder for genuinely sustainable companies to compete.

 Why Packaging Greenwashing Matters

Industries relying heavily on packaging—electronics, consumer goods, food service— have created a plastic waste crisis. As environmental consequences becomeapparent, companies rush to position themselves as sustainability leaders.Unfortunately, this has led to an explosion of greenwashing tactics.

The stakes are high:

.     70% of U.S. consumers care more about sustainability than in the past (Statista, 2024)

.    The U.S. generates 48 million tons of plastic waste annually

.     Only 5-6% is actually recycled (Department of Energy)

.    The  sustainable  packaging  market  hit  $266  billion  in  2024,  projected to  reach  $413 billion by 2030

When buyers can’t distinguish real solutions from fake ones, everyone loses—except the companies doing the greenwashing. 

Red Flag #1: Vague and Misleading Terminology

What It Looks Like

Packaging covered in words like ”eco-friendly,” ”green,” ”natural,” or ”earth- conscious”—with zero specifics about what makes it sustainable.

Why It’s Problematic

These terms have no legal definition. A product labeled ”eco-friendly” might contain just 2% recycled content. We’ve seen companies call petroleum-based plastic “green” because they added plant-based dye. For example, ”biodegradable” simply means an item can break down into smaller pieces over time—a process that applies to nearly all materials, including plastics, given enough time. It doesn’t specify how long, under what conditions, or whether the breakdown is actually beneficial.

What to Look For Instead

.     Specific percentages: ”Contains 75% post-consumer recycled PET”

.     Quantified benefits: ”Reduces carbon emissions by 32% vs. virgin plastic”

.     Real standards: ”ASTM D6400 certified for industrial composting”

.     Precise conditions: ”Compostable within 90 days at 60°C”

Quick Test: No numbers or standards = marketing luf. 

 Red Flag #2: Misleading Imagery and Symbols

What It Looks Like

Nature imagery (leaves, trees, green colors) that creates a false perception of environmental responsibility. Or recycling symbols that don’t guarantee recyclability.

The Deception

Colors and nature-related symbols in branding aren’t regulated. Photos of forests can evoke sustainability while the actual product contributes to deforestation.

The Recycling Symbol Problem

One of the most widespread examples involves the recycling symbol—a number  inside three interlocking arrows. While the numbers are resin identification codes indicating plastic type, they lead consumers to assume the plastic is recyclable.

The reality:

.     Only #1 (PETE) and #2 (HDPE) are widely recycled (~75% of programs)

.     #3-7 are rarely recycled in practice

.    The EPA has asked the FTC to reconsider these symbols due to consumer confusion

According to 2023 EPA data:

.     U.S. plastic recycling rate: 8.7%

.     For packaging specifically: 14.5%

.     Everything else gets landfilled or burned

Polystyrene (#6) is a prime example. Frequently marketed as ”recyclable,” it’s made from hydrocarbons derived from nonrenewable petroleum. Resistant to decomposition, polystyrene occupies around 30% of landfill mass globally—yet only about 6 facilities nationwide actually recycle it.

What to Do

.     Look for How2Recycle labels (from GreenBlue) with location-specific info

.    Ask: ”What percentage of facilities in our region accept this?”

.     Verify: ”Has the recycling market been stable for 3+ years?”

Red Flag #3: The “Biodegradable” Misrepresentation

The Problem

“Biodegradable” is the most abused term in packaging. Technically, everything biodegrades given enough time—that plastic fork will break down in about 450 years.

The Scandal

Between 2010-2019, millions of ”biodegradable” plastic bags were sold using oxo- degradable technology. Manufacturers claimed environmental breakdown. EU research revealed they simply fragmented into microplastics, creating worse pollution. The EU banned them in 2021.

What Research Shows

A 2023 Plymouth University study tested 203 ”biodegradable” products:

.    After 3 years in soil: 83% remained intact

.    After 3 years in ocean: 91% showed no degradation

.     Meeting real standards: Only 14%

The Standards That Actually Matter

ASTM D6400 (US) / EN 13432 (Europe):

.     Requires 90% biodegradation within 180 days

.     In industrial composting (58°C ±2°C, controlled humidity)

.     Resulting compost must be non-toxic

.     Requires third-party testing

The Infrastructure Gap

Companies may market packaging as ”biodegradable” when it only meets minimum regulatory standards and won’t break down in natural environments or standard landfills. Industrial composting facilities exist in only 185 U.S. cities—serving about 5% of the population. For 95% of consumers, ”compostable” products end up in landfills where they won’t break down.

Questions to Ask

1.   ”What specific standard—ASTM D6400 or EN 13432?”

2.   ”Home compostable or industrial compostable?”

3.   ”Can you share third-party test results showing degradation rates?”

No clear answers = walk away.

 Red Flag #4: Exaggerated Environmental Claims Without Proof

 Red Flag #5: The Bio-Based Confusion

 Red Flag #6: Lack of Supply Chain Transparency

Ever noticed a brand bragging about sustainable packaging but dodging questions about where it comes from? That’s a red flag. Many companies hide high-polluting practices—like using compostable packaging from suppliers that destroy forests, or hyping small packaging changes while running emission-heavy facilities. Remember TerraCycle? They built a “zero waste” brand but were caught warehousing or landfilling most of the material they collected. Real transparency—like Patagonia’s Footprint Chronicles or Interface’s Carbon Dashboard—means sharing full supply chains, warts and all. If a supplier says “that’s proprietary” or hands you a marketing deck instead of real data, they’re hiding something.

Red Flag #7: The Virgin Material Trap

New regulations push brands to use more recycled plastic (PCR), but the truth is—there’s not enough recycled plastic to go around. That’s why so many companies claim sustainability while still relying on virgin materials. Existing factories are built for virgin plastic’s consistent quality; recycled plastic varies, raising costs and risking product performance. Virgin plastic comes from fossil fuels, driving emissions and pollution—but the real fix isn’t just more recycling—it’s compostable materials (like Cruz Foam, made from upcycled food waste) that break down naturally. Next time, ask: How much is virgin vs. recycled? Why can’t you use 100% recycled? And have you considered compostable alternatives?

How to Verify Claims Yourself

Check certification databases:

1.   BPI Compostable:bpiworld.org/BPI-Public-Database

2.   FSC Forest Products:info.fsc.org/certificate.php

3.   How2Recycle:how2recycle.info

If the certification number isn’t listed, it’s not certified.

Corporate cafeteria (2023):

.     Switched to ”recyclable” #5 PP containers

.     Local MRF doesn’t accept #5

.     Result: Zero environmental benefit, contaminated recycling stream

Cofee chain (2021):

.     Marketed ”plant-based” cups heavily

.     Customer backlash when cups weren’t actually compostable

.     Result: Reputation damage from social media

This is the norm for buyers who don’t verify.

 Why Greenwashing Backfires

Brands caught misrepresenting sustainability eforts face:

.     Legal action for false advertising

.     Reputation damage that’s hard to repair

.     Customer backlash on social media

.     Loss of competitive advantage as trust erodes

 The Opportunity

Businesses that prioritize genuine sustainability:

.     Build customer loyalty: 70% of consumers care more about sustainability

.     Future-proof operations: Stay ahead of regulations

.     Reduce costs long-term: Eliminate waste and improve efficiency

.    Attract conscious consumers: Premium pricing for authentic sustainability
