One-line takeaway: Positioning sustainable products as the default, standard option rather than the unusual alternative can help close the gap between consumers’ green intentions and real action.
The grocery store is bustling with people on a busy weekend afternoon, yet the natural food aisle sits quiet. Shoppers pass over organic oatmeal, sustainable soaps, and eco-friendly cleaning products, flocking to familiar packaged goods and single-use plastic bottles.
Consumer demand for sustainable products is at an all-time high, so why aren’t eco-friendly items flying off the shelves? In theory, sustainability sells, but in practice, the “green consumer” is surprisingly elusive. Companies shifting toward sustainability are all too familiar with this paradox. According to one recent survey, 65% of consumers want to buy from sustainable brands, while only 26% actually do so.1
It’s easy to think sustainable products fail because they’re hard to find or cost too much, but the data says otherwise. The percentage of sustainable products on the market is steadily increasing, and most consumers are willing to pay a premium for them.2,3 Could it be that consumers simply don’t care enough? When three-quarters of people are concerned about how their purchases impact the environment, the issue isn’t apathy, either.4
What if the problem isn’t about cost, access, or motivation, but about design? Behavioral science suggests that choice context—the circumstances surrounding a shopping decision—can have a subtle yet powerful influence on what people buy. Think about the context surrounding sustainable products. Often, these items are positioned as an alternative option or a diversion from the norm. They’re relegated to “eco-friendly” grocery store aisles, separate product listing pages, or niche brand lines, while traditional products take center-stage as the default choice in checkout lines, shipping forms, and shopping apps.
Would green products perform better if they weren’t being sidelined to specialty aisles and shopping categories? Are consumers more likely to make sustainable choices if they’re integrated into everyday choice environments and positioned as the new standard?
This article explores why narrowing the intention-action gap in green consumption is less of a marketing issue and more of a design problem, where presenting sustainability as the status quo can make green products feel more normal, natural, and convenient.
Why Consumers Are Drawn to Defaults
It’s a well-known fact that consumer choices aren’t always perfectly rational. People overwhelmingly go along with pre-selected options, choosing the path of least resistance instead of making an active decision to opt for something else, even if that “something else” is somehow better. The tendency for consumers to stick with defaults—options that are automatically selected unless an alternative is specifically chosen—is a highly predictable behavioral pattern.5
There are a couple of key reasons consumers are drawn to defaults. Whether it’s eye-level store products, standard shipping options on checkout forms, or restaurant dishes at the top of the menu, choosing defaults is easy—it requires no exhaustive research, deliberate decision-making, or excessive mental effort. When it comes to minimizing cognitive load, defaults always outperform alternatives. This is why consumers are even more likely to select default products when they’re pressed for time.6
Beyond being convenient, defaults also convey important social cues to shoppers. Research shows that default options are often seen as implicit endorsements, indicating what’s “best” or socially acceptable.5 Consider how, on a restaurant menu, meat-based mains often feel like the recommended choice, while vegetarian alternatives seem more like atypical substitutions or subpar changes. In some cases, this endorsement effect is even stronger than the convenience of sticking with the status quo.7
When defaults deter consumers from choosing sustainable products, the solution isn’t informational marketing, but changing the decision environment. Research shows that behavioral design, called choice architecture, is incredibly effective at nudging consumers toward climate-friendly shopping choices. In fact, design-based nudges often work even better than information-based interventions like carbon footprint labels or persuasive messaging.8
Making Green the Automatic Choice
Defaults reveal a hidden truth about how people make choices—we don’t always choose products that fit with our values or attitudes, but lean toward options that feel easy and normal. How can we make sustainable products feel like intuitive choices rather than deliberate, conscious decisions?
Today, forward-thinking companies are exploring the subtle power of green defaults, a simple and cost-effective way to nudge well-meaning customers toward eco-friendly products. Even without marketing or promotion, small shifts in the shopping environment—either online or offline—can subtly change how consumers perceive eco-friendly products.
A growing body of research supports this emerging idea. For example, Dutch researchers recently experimented with different nudges encouraging online shoppers to choose pick-up point delivery over less sustainable residential shipping.9 Compared with informational nudges (showing CO2 reductions or green leaf icons indicating sustainable options), default nudges (where pick-up was automatically selected) were the most effective at steering shoppers toward sustainable delivery options. Similarly, lab studies and real-world experiments show that green defaults are highly effective at increasing renewable energy adoption. Many consumers stick with default green energy plans instead of opting out, even if they cost slightly more.10
These studies reveal how defaults can encourage shoppers to overcome common barriers in green product adoption, such as cost and convenience. What makes these simple design interventions so effective? Green defaults aren’t just about ease, but about communicating what’s normal.
Defaults tell people what kind of behavior is expected, desirable, or correct in a social context, tapping into our innate need to align with social norms and make decisions that solidify our sense of belonging. It’s like a worn path cutting through an expanse of lawn: we naturally follow the footsteps of others, not necessarily because the path is better than the sidewalk, but because following it feels effortless, natural, and socially acceptable.
Some companies are leveraging this behavioral tendency to promote plant-based food choices. Simply incorporating vegan and vegetarian options into traditional choice environments can increase their popularity—vegan meat alternatives like Beyond Meat sell 67% better in meat sections than on niche vegan shelves.11 How an eco-friendly product is labeled or branded can also shape its perception. For example, people are less likely to choose meals labeled “vegetarian” than identical meals without any label.12 Researchers think this is because “vegetarian” or “vegan” labels convey a sense of otherness that can deter omnivores from choosing plant-based options.
Whether it’s black bean burgers or biodegradable soap, eco-friendly brands are increasingly turning toward subtle, normalized framing instead of niche or specialty labels. The more sustainable products are woven into the fabric of our everyday lives, the less they feel like special alternatives or fringe options, and the more they become a regular part of our routines.
Shifting from Persuasive Marketing to Behavioral Design
Successfully selling sustainable products isn’t just a matter of good marketing, but smart behavioral design. As we’ve seen, subtle design tweaks to shopping environments can often be more powerful at shifting behavior than educational information or persuasive messaging.
It’s time we start thinking about sustainable product adoption as a design challenge rather than solely an awareness issue. While defaults are not a miracle fix for failing products, they can be powerful at encouraging sustainable product uptake when consumer intentions are there, but action is lacking.
Those rows of sustainable cleaners collecting dust on store shelves tell a story about how people make decisions. Convincing consumers to care about eco-friendly products is not enough to drive behavior when their less sustainable counterparts still feel like the easy, obvious choice. Rather than tucking sustainable products away and hoping that well-intentioned shoppers will hunt them down, building them into the flow of regular shopping can make sustainable choices feel not just effortless, but ordinary.
