Because let’s be honest: those aren’t always the same thing.
Glass, aluminum, paper wraps, matte finishes, earthy colors, clear packaging, and minimalist design can all shape consumer perception of sustainable packaging in a matter of seconds. And when you work in packaging, that matters. We care about the assumptions people make. We care about what cues they respond to. But we also care about whether the package is actually doing the job in a more sustainable way, not just borrowing the look of sustainability to help sell products.
Watch the full episode above or listen now on Spotify, Apple Podcasts, or our website. Until then, here’s a look at a few of the biggest moments from the conversation.
First, we kicked things off with a brand-new lightning round game. Natalie held up pairs of packages and asked two simple questions:
What do we think consumers would gravitate to as the more sustainable option?
What do we think is actually more sustainable once you look at the full picture?
Metal can feel reusable, glass can feel cleaner or more premium, paper can feel natural. Plastic often starts the race a few steps behind before anyone even gets to the label.
So between these options, go with your gut: which one are you grabbing off the shelf?
Aluminum water bottle vs. plastic water bottle
Glass yogurt jar with a paperboard wrap vs. polypropylene yogurt cup
Glass tea bottle vs. plastic tea bottle
Got your answers locked in? Then let’s explore what happens when you look past the first impression. What’s the carbon footprint of the package and the process behind it? How much energy does it take to make? How much heavier is it to move? How efficiently does it ship? What happens to it in the recycling stream?
Mike put it in the clearest possible terms: “The lens that I use when I think about packaging sustainability is, what’s the carbon footprint of the process and the output package? The carbon footprint for aluminum conversion into cans is higher than the plastic bottle concept, and that’s really the whole reason. Both are sustainable, but the question is: what’s more sustainable?”
We won’t spoil where we landed on each matchup here. Watch the video to see which packages seem like the obvious pick at first glance and which ones start to look a little different once the tradeoffs come into view.
A lot of consumers want to make the more sustainable choice. The interest is there. Natalie brought in a 2023 Trivium Buying Green Report showing that 71% of consumers actively prioritize products with sustainable packaging, 59% look for recycling and sustainability information on labels, and 80% are interested in refillable packaging.
But wanting to make the right choice and knowing how to make it are two very different things.
We try to make good decisions, but our brains are also looking for shortcuts the whole time — and most of them aren’t conscious. We see a package, we get a quick impression, and we start assigning meaning to it before we’ve really thought it through. That’s where a lot of the psychology behind consumer perception of sustainable packaging shows up.
Some of the things that can make a package feel more sustainable are:
Brown paper
Matte textures
Earthy colors
Minimalist design
Visible fiber or pulp
Muted print colors
Green packaging cues
None of those things automatically make a package more sustainable, but they can make it feel more natural, simple, healthy, or environmentally responsible in a split second.
One example really captures that. Natalie mentioned a past project where a plastic bowl was color-matched to look like molded fiber because the brand believed people would read it as more sustainable. The material didn’t change, but the signal did. And that kind of small visual shift can change how a package is read right away.
That’s part of what makes this such a tricky problem for food packaging. We want to send the right signal, but we also don’t want to build a less sustainable or effective package just because it helps trigger the “green” response faster.
On a single trip to the grocery store, our brains are making tens of thousands of assessments and decisions, and we are wired to do it in seconds.
That’s why details like these matter:
Matte surfaces can feel less processed
Off-white or earthy tones can feel softer or more natural
Green can suggest health or sustainability
Minimalist layouts can feel cleaner or more responsible
Clear packaging can suggest honesty, freshness, or quality
Sometimes sustainability and quality start getting bundled together in people’s minds. If a package feels more honest, more premium, or more transparent, it can start to feel more trustworthy overall.
“Can you imagine that on any single visit to the grocery store, our brains make tens of thousands of assessments and decisions?” asks Mike. “We’re really wired to make that assessment in just a couple of seconds. The idea of adding really factual and declarative verbiage or symbols to packaging that would help people make those decisions probably only works on .1% of consumers.”
That is why visual cues can influence packaging decisions long before consumers compare materials, claims, or life cycle data.
That doesn’t mean the facts don’t matter. It just means most people aren’t starting there.
One of the most frustrating parts of this whole topic is how easy it is for a package to look more sustainable without actually being more sustainable.
A 2023 study by the Journal of Consumer Research found that consumers often judge plastic packaging with added paper to be more environmentally friendly than the same plastic packaging without paper. Add a paper sleeve to plastic, and many people assume the package improved — even when it now uses more material and may perform worse environmentally.
That lines up with a shortcut a lot of people already carry around in their heads: paper good, plastic bad.
And once that belief settles in, it can be hard to move. Familiar ideas tend to stick, even when the data gets more complicated than the slogan. That matters for all of us in packaging, because it creates real pressure to add components, textures, wraps, or visual cues that may help sell the story while pulling the package in the wrong direction environmentally.
When considering consumers’ ideas about sustainability, it’s important to consider their point of view — literally. People see litter and ocean plastic. They see headlines, videos, and images that stick in their minds. They hear about microplastics and the persistent news about plastic everywhere. Over time, all of that builds a very strong emotional picture. Plastic starts to feel like the problem before any comparison even begins.
We’ve talked before about how the way people talk about plastics shapes the way they think about them, and that baggage shows up long before anyone starts comparing real sustainability tradeoffs. So when someone sees a glass jar, a paper wrap, a muted label, or a soft green color, it’s easy for that package to feel like the better choice right away. It looks calmer, cleaner, more natural. More sustainable. What they don’t see is the heat required to make glass or aluminum, the transportation impact of heavier formats, how efficiently one package ships compared with another, or what happens when a package underperforms and product gets wasted.
That’s where the gap opens up. The first impression is built on what people can see and feel in a moment. The bigger sustainability picture is usually hiding somewhere else.
A lot of packaging labels talk about recyclability. Many of them talk about recycled content. Much less packaging says anything about lower production energy, lower greenhouse gas emissions, or broader system tradeoffs compared with alternatives.
We’d love to tell the whole story. The problem is, most packages don’t exactly give you much room to work with. A yogurt cup is already doing a lot. It’s protecting product, carrying the brand, handling required information, and trying to stand out in a crowded aisle. There usually isn’t much space left for a mini lesson in life cycle assessment.
And even if there were, that still leaves the hard part: how do you say something meaningful without turning the package into a wall of claims? How do you explain a real tradeoff without oversimplifying it into nonsense? And how do you do any of that without drifting into greenwashing?
As Natalie put it, when comparing two options that are recyclable on the surface, “Yes, they’re both recyclable, but that’s not the differentiator from sustainability. The differentiator from sustainability is in that life cycle analysis data. There’s never any mention of, ‘This package reduced greenhouse gas emissions by x percent.’ Why aren’t we putting that on the bottle?”
That’s the challenge. The full story matters. But it’s a big story for a very small space.
People aren’t reading packaging like packaging professionals do. They’re reading signals, making quick judgments, and doing their best with the information in front of them.
That’s why packaging can’t rely on one signal, one claim, or one material story to do all the work. Performance, recovery, and communication all matter. And so does understanding the psychological triggers people are reacting to in the first place. Sometimes the decision is conscious. A lot of the time, it isn’t. It’s a quick visual read, a gut feeling, a familiar shortcut. That’s exactly why this topic matters so much in food packaging.
And if we’re going to ask consumers to care, we have to care too — not just about what looks sustainable, but about what actually holds up when you look at the whole system.
Thanks for tuning in to the latest episode of Crazy About Packaging. This one got into a part of food packaging that shows up every day but doesn’t always get called out directly: the gap between what packaging signals and what packaging actually does.
