What Customers Expect from Businesses on Sustainability in 2026

The Data: Customers Say They Care

If you want to know whether your customers care about sustainability, the survey data is unambiguous. They say they do. Consistently, across years, across demographics, across geographies.

NielsenIQ found that 78% of US consumers say a sustainable lifestyle is important to them. That number has held steady for several years, which tells you this is not a passing trend. It is a baseline expectation that has settled into consumer consciousness.

Deloitte's 2024 Sustainable Consumer report tracked the percentage of consumers who changed their behavior due to sustainability concerns. The number increased across every category they measured: food, clothing, personal care, household products, and more. This is not just people answering a survey question the way they think they should. This is people reporting actual changes in how they shop, what they buy, and which brands they stick with.

McKinsey and NielsenIQ published a joint analysis in 2023 that looked at five years of retail sales data. Products making ESG-related claims (environmental, social, or governance) grew 28% cumulatively over that period. Products without such claims grew 20%. That 8-point gap represents real revenue, not survey responses. It showed up in cash registers across the United States.

IBM's 2022 global consumer study reported that 49% of consumers paid an average premium of 59% for products they perceived as sustainable or socially responsible in the prior 12 months. Nearly half of consumers, paying more than half again the standard price. That number surprised a lot of people when it came out, and it deserves some scrutiny (more on that below).

Here is the honest caveat: these are stated preferences from published surveys. Every one of these studies is directionally useful, but none should be taken as a precise prediction of how your specific customers will behave. Survey respondents tend to overreport their sustainability commitment. The IBM premium number in particular likely captures what consumers paid for products they perceived as sustainable, not necessarily what they paid specifically because of sustainability. A $6 organic yogurt might be chosen for taste and bought at a farmer's market for convenience, with sustainability as a secondary factor.

Still, the direction is clear. Consumer interest in sustainability is real, it is growing, and it shows up in purchasing data, not just survey responses. The question is not whether customers care. It is how that caring translates into the decisions they make when they are choosing between your business and your competitor.

What “Caring About Sustainability” Means in Practice

There is a well-documented gap between what consumers say and what consumers do. Behavioral economists call it the intention-action gap or the attitude-behavior gap. In sustainability, this gap is wide enough to drive a truck through.

People tell pollsters they care deeply about the environment. Then they buy the cheapest option on Amazon. This is not hypocrisy. It is human behavior. Price and convenience dominate most purchasing decisions. They always have. Sustainability rarely overrides those two factors when there is a significant difference.

But here is the part that matters for your business: when price and convenience are roughly equal, sustainability becomes the deciding factor. Researchers call this the tie-breaker effect, and the evidence for it is strong.

Think about the last time you chose between two coffee shops that were equally close, equally priced, and equally good. One has a sign about sourcing fair-trade beans and supporting local farmers. The other has no such sign. You probably walked into the first one. Not because you went out of your way to find a sustainable coffee shop. Because all other things being equal, the sustainability signal tipped the scale.

This is how sustainability actually works in consumer decisions. It is not the primary driver. It is the differentiator when primary drivers are a wash. And for most small and mid-sized businesses, your competitors are already similar on price, quality, and convenience. You are operating in exactly the zone where the tie-breaker effect matters most.

The practical takeaway: you do not need to be the cheapest option or the most sustainable company on earth. You need to be competitive on price and quality (which you probably already are) and then give customers a reason to choose you over a comparable alternative. A visible, verifiable sustainability commitment does that. One specific example: a tree planting subscription that you can point to on your website, in your email signature, and in your proposals. It gives customers a concrete reason to prefer you when everything else is similar. For how to calculate whether that investment pays off, see ROI of Business Tree Planting.

The flip side is also true. When sustainability imposes a real cost on the consumer (higher prices, longer delivery times, less convenience), most consumers choose the conventional option. This is not a failure of values. It is a budget constraint. It means that the most effective sustainability strategies for your business are ones that add value for the customer rather than asking the customer to sacrifice. Planting trees through your business does not raise your prices or slow your delivery. It adds a positive signal at zero cost to the buyer.

Generational Differences

Not every generation cares about sustainability in the same way or to the same degree. Understanding the differences helps you calibrate your messaging and decide where to invest.

Gen Z (born 1997–2012). This generation reports the highest stated concern about environmental and social issues, across virtually every survey conducted in the past five years. A 2023 Deloitte survey found that climate change is Gen Z's top concern globally. They are more likely than any other generation to say they have stopped purchasing from a brand due to ethical or sustainability concerns.

But Gen Z is also the most skeptical generation when it comes to corporate sustainability claims. They grew up watching companies put green labels on the same products and call it progress. They can spot vague claims instantly. “We care about the planet” means nothing to a Gen Z consumer. “We plant 25 trees every month through verified reforestation partners, and here is the certificate to prove it” means something. For this generation, specificity and proof are non-negotiable. For a deep look at what constitutes proof versus posturing, see How to Avoid Greenwashing.

Gen Z's purchasing power is growing rapidly. The oldest members of this generation are now 29. They are early in their careers, starting businesses, making purchasing decisions for organizations. Their influence will only increase over the next decade.

Millennials (born 1981–1996). This generation currently holds the most spending power among sustainability-conscious consumer segments. They are 30 to 45 years old, in their peak earning and spending years, and many are in decision-making roles at their companies. A 2023 First Insight report found that 75% of millennials are willing to pay more for sustainable products, the highest of any generation.

Millennials are less skeptical than Gen Z but more discerning than older generations. They want to see action, not just promises, but they are less likely to do deep research into your claims. A visible badge, a partner directory listing, or a line in your email signature about tree planting is often enough to register as a positive signal. They do not need to read your entire sustainability report. They need to see that you have done something concrete.

For B2B businesses, millennials are particularly important because they are now the primary decision-makers for vendor selection at many companies. They bring their personal values into professional purchasing decisions. A 2024 Forrester study found that 68% of B2B buyers under 40 consider a vendor's sustainability practices when evaluating proposals.

Gen X (born 1965–1980) and Baby Boomers (born 1946–1964). These generations report lower stated priority for sustainability in purchasing decisions, but the trend is moving in the right direction. NielsenIQ data shows that sustainability awareness among consumers over 50 has grown significantly in the past five years, particularly for tangible environmental actions like tree planting, clean water, and wildlife conservation.

Gen X and Boomers respond best to straightforward, results-oriented messaging. They are less interested in your values statement and more interested in what you have actually done. “We have planted 1,200 trees this year” lands better with this demographic than “we are committed to a more sustainable future.” Numbers and tangible outcomes beat aspirational language.

One important note: generational stereotypes are useful as broad patterns but unreliable as predictions for any individual customer. A 60-year-old business owner may care more about sustainability than a 25-year-old consumer, depending on their personal values and industry. Use generational data to inform your strategy, not to define it.

B2B vs. B2C

Sustainability expectations play out differently in B2B and B2C contexts. If you sell to consumers, the dynamics above apply directly: the tie-breaker effect, generational preferences, and the intention-action gap all shape individual buying decisions.

B2B sustainability pressure is different. It is more structural and less emotional. It shows up in three specific places.

RFP requirements. More companies are including sustainability questions in their Requests for Proposals. A 2024 EcoVadis survey found that 67% of large companies now include sustainability criteria in their procurement process. If you sell to mid-size or enterprise companies, you will increasingly see questions like: “Describe your company's environmental sustainability practices” or “Do you hold any environmental certifications?” Having a specific, documented answer (we plant trees monthly through verified reforestation partners, here are our certificates) is materially different from leaving that section blank or writing “we are committed to sustainability.”

Vendor selection and audits. Beyond RFPs, existing clients are increasingly conducting sustainability audits of their supply chain. This is partly driven by regulation (the EU Corporate Sustainability Reporting Directive, for example, requires large companies to report on their supply chain's environmental impact) and partly driven by their own customers asking the same questions. Sustainability expectations cascade downward through supply chains. Your client's client asks them about sustainability. They ask you. This is the B2B multiplier effect.

Partnership and co-branding. When two businesses partner on a project, each one's reputation reflects on the other. Companies are increasingly reluctant to partner with businesses that have no visible sustainability commitment. Not because they are zealots, but because their own customers and stakeholders might ask questions. Having a documented sustainability practice (even a modest one, like a tree planting subscription) makes you a safer partner.

The B2B dynamic is less about whether individual decision-makers personally care about the environment (though many do). It is about structural incentives. Companies need to demonstrate sustainability across their operations, and that means preferring vendors who can document their own commitments. This is not a trend that will reverse. The regulatory pressure is increasing, not decreasing. The practical question for B2B businesses is whether you want to be ready when a client asks, or scramble to answer after you have already lost the deal.

The Cost of Doing Nothing

Most articles about sustainability focus on the benefits of action. Here is the other side: what happens when you do nothing. The cost of inaction is harder to measure than the cost of a $29 per month subscription, but it is real and it compounds.

Talent acquisition. Employees, especially younger ones, prefer employers with sustainability commitments. A 2024 Deloitte Global survey found that 44% of Gen Z and 40% of millennials have already rejected a job or assignment based on personal ethics or sustainability concerns. A 2023 IBM Institute for Business Value study reported that 67% of respondents are more willing to apply to and accept positions with environmentally sustainable companies.

For a small business competing for talent against larger companies, every differentiator matters. Salary and benefits are hard to match when you have 10 employees and your competitor has 10,000. Culture and values are where small businesses can compete. A visible sustainability commitment is a signal that costs relatively little but communicates something meaningful about what kind of company you are. When a candidate is choosing between two similar offers, the company that plants trees and supports its community has an edge over the one that does not. This is the tie-breaker effect applied to hiring.

Client retention. ESG requirements cascade through supply chains, as discussed in the B2B section above. If you are a vendor or subcontractor, your client's sustainability reporting requirements can become your problem. When a client asks you to document your environmental practices and you have nothing to show, you are not necessarily fired immediately. But you have given them a reason to look at alternatives. And the next vendor who bids on your contract will probably have something to show.

The pattern is subtle but consistent: companies do not typically drop a vendor explicitly for lacking sustainability credentials. They add sustainability to the evaluation criteria, and the vendor without credentials scores lower. Over time, this creates a structural disadvantage that compounds. The first client you lose to a more sustainability-visible competitor is hard to trace back to a single cause. The fifth one is a pattern.

Brand risk. Silence on sustainability is increasingly interpreted as indifference. Five years ago, having no sustainability statement on your website was the default. Most businesses did not, and nobody noticed. Today, more of your competitors have something to say about it, even if it is modest. When a potential customer compares your website to a competitor who prominently features their tree planting badges, their volunteer program, and their commitment to verified reforestation, your silence looks like a choice. It looks like you decided not to care.

This is not about being perfect. It is about being present. A simple tree planting subscription with a badge on your website moves you from the “says nothing” category to the “doing something real” category. That shift matters more than the scale of what you are doing. Customers, particularly younger ones, distinguish between businesses that are trying and businesses that are silent. They are much more forgiving of small efforts than they are of no effort at all.

The cost of doing nothing is not a single dramatic event. It is a slow erosion: slightly harder to hire, slightly easier to lose clients, slightly less competitive in RFPs, slightly less appealing to the next generation of customers. Each of these is small on its own. Together, they create a meaningful disadvantage that grows each year you wait.

Starting Small Works

The biggest barrier to sustainability action is not cost. It is the belief that you need to do something large and comprehensive to make it count. You do not.

The research consistently shows that customers respond to specific, verifiable actions more than to ambitious but vague commitments. “We plant 10 trees every month through verified reforestation partners” beats “we are committed to reducing our environmental footprint across all operations” in every consumer test, every time. The first statement is concrete, checkable, and real. The second is the kind of language that makes people roll their eyes.

This is the “one visible action” approach. Pick a single, specific, verifiable commitment and make it visible. Put it on your website. Mention it in your proposals. Add it to your email signature. Display the badge. The goal is not to solve climate change. The goal is to move from the “doing nothing” column to the “doing something real” column. That single step is worth more, in terms of customer perception, competitive positioning, and employee satisfaction, than all the sustainability strategy documents that never get executed.

Here is what “starting small” actually costs. A ForestMatters Seedling plan is $29 per month. That is 10 trees planted monthly through verified reforestation partners like Ecologi and Digital Humani. You get a badge for your website, quarterly impact certificates, and verifiable documentation. Annual billing brings it to roughly $24 per month (17% discount). For the cost of a team lunch, you have a documented, specific, ongoing environmental commitment.

If $29 per month is meaningful to your business, that is completely fair. But consider the alternative: doing nothing costs you credibility, competitive positioning, and potentially clients and employees, without saving you much. The ROI calculation is not about whether tree planting generates direct revenue. It is about whether the absence of any sustainability action costs you more than $29 per month in lost opportunities. For most businesses, the answer is obviously yes.

The businesses that get this right start with one action and build from there. They do not wait until they can afford a comprehensive sustainability program. They plant 10 trees a month, put the badge on their website, and mention it when relevant. Six months later, they add a volunteer day. A year later, they upgrade to a higher tier or add another commitment. The program grows organically because it started with something real instead of a plan that never got executed.

The data from the surveys above tells a clear story. Customers care about sustainability. They reward businesses that take visible, specific action. They are skeptical of vague claims and forgiving of small efforts. The cost of inaction compounds over time. And the barrier to starting is lower than most business owners assume.

You do not need to transform your entire operation. You do not need a sustainability director or a consultant or a 50-page strategy document. You need one visible, verifiable action that you can point to when a customer, a client, a potential hire, or an RFP asks what your business does for the environment.
