We spend a lot of time in this industry talking about what couples want. Their colours, their catering, their guest lists, their budgets. But there is a quieter conversation happening underneath all of that, and the latest research suggests it is one we cannot afford to ignore any longer. Couples, and the people around them, are no longer simply wondering whether businesses care about people and planet. They are looking for proof, and increasingly, they expect us to talk about what we are doing.
The numbers behind the shift
New research from 1% for the Planet, published this month, found that 74% of Britons believe UK businesses have a responsibility to financially contribute to environmental initiatives. Even more striking, more than half of people say this summer’s very hot weather has increased their sense of urgency around environmental action, a figure that rises to 70% of Gen Z and 63% of Millennials. With just 1% of UK private sector turnover representing around £55 billion every year, the public can see the scale of what business could unlock.
Expectations are not coming from a vocal minority. They are coming from the very generations filling our booking calendars. 84% of Gen Z and 82% of Millennials agree that businesses have a responsibility to contribute to environmental initiatives, and when asked where those contributions should go, climate and decarbonisation alongside conservation and restoration top the list.
Now layer the wedding data on top. Bridebook’s UK Wedding Report 2026, drawn from more than 7,000 couples, shows that 83% of couples now make a sustainable effort in at least one element of their wedding, and nearly a quarter include second-hand or vintage details. Meanwhile WedPro’s 2026 industry report shows the proportion of couples considering green elements in their plans has climbed to 81%, up from 70% the year before. Sustainability is not a niche any more. It is the mainstream, and it is growing.
Put those two sets of figures together and the message is unmistakable. The people planning weddings are the same people telling researchers that businesses must act, and must be seen to act. Gen Z alone is now 34% of engaged couples. These are couples who grew up in a climate crisis, and they are bringing those expectations to every supplier they meet, from the venue coordinator to the cake maker.
Doing the work is not the same as talking about it
Here is where many wedding and events businesses stumble. They are doing genuinely good things. They have switched to renewable energy tariffs. They source locally and seasonally. They have cut single-use plastics, built waste into their planning, paid their staff properly. And then they say nothing, because talking about it feels uncomfortable. It feels like boasting. It feels, if we are honest, a little like greenwashing territory.
But here is the problem with silence. When one business stays quiet about its genuine efforts, couples can only compare the businesses that are shouting. And too much of what is being shouted is vague. More than half of Britons, 52%, say they do not trust the environmental and sustainability claims that UK companies typically make in their marketing and advertising. That scepticism does not just hurt the greenwashers. It taints every business that says anything at all, and it makes the quiet, honest businesses invisible.
There is a real cost to that invisibility, and it is commercial. In the same research, 51% of people said they would be more likely to choose a company with independent third-party certification when deciding between two similar products or services. Among Gen Z that figure jumps to 73%, and among Millennials to 61%. In an industry where the average wedding involves choosing between dozens of similar suppliers, certification is not a nice-to-have. It is a differentiator.
Kate Williams, CEO at 1% for the Planet, captured the tension perfectly when she said businesses need to demonstrate that their contribution is real, because simply making another green promise is not enough. Demonstrating is the operative word. Not claiming. Demonstrating.
Why the wedding and events sector is uniquely placed
Weddings and events occupy a particular position in the economy. They are emotionally charged, highly visible, and deeply social. A wedding brings together fifty, a hundred, two hundred people, most of whom will attend several events a year and see the same suppliers at work. Every wedding is a showcase. Every couple is a storyteller, and every guest is a potential future customer, sitting in your venue, eating your food, photographing your flowers.
That visibility cuts both ways. If a supplier gets it wrong, the story travels through group chats and planning forums. But if a supplier gets it right, the story travels just as fast. When couples see a venue with solar panels and battery storage keeping the party going through a heatwave, when they watch a florist explain why the peonies have been swapped for something locally grown that morning, when they hear a caterer talk about where the flour in the sourdough came from, they remember. They talk. They recommend.
This is also a sector where the people doing the work are, overwhelmingly, small businesses. Small businesses often assume the responsibility conversation is aimed at big corporations, and it is true that 54% of people see large corporations as bearing the greatest obligation. But 30% say all businesses should contribute the same percentage of turnover regardless of size, and couples do not distinguish in the way the statistics do. To a couple choosing between you and the venue down the road, you are both simply businesses, and both are being measured.
Responsibility is more than the environment
It matters that we frame this properly. Acting responsibly to people and planet is not just about carbon. It is about how staff are paid and treated through long event days. It is about the supply chain behind every product, the growers, makers and manufacturers. It is about accessibility, inclusion, and the way we welcome every couple and every guest. It is about the communities our businesses sit within. Couples notice all of it, and increasingly they ask about it.
The 1% for the Planet research asked where business contributions should be directed, and while climate led, conservation and restoration followed closely behind. People expect breadth. They expect businesses to think about nature as well as carbon, people as well as planet. The good news is that most wedding businesses are already doing more of this than they give themselves credit for. The work is happening. The gap is the talking.
How to start the conversation, credibly
So how does a wedding or events business talk about responsibility without sliding into the greenwashing that 52% of the public already distrusts? Three principles.
First, be specific. Vague claims invite scepticism; specifics invite trust. Instead of “we care about the environment”, say “our electricity comes from a renewable tariff, and we have cut food waste by a third through smarter menu planning”. Facts are credible. Adjectives are not.
Second, be accountable. Independent verification matters, and the research bears that out. This is precisely why the Sustainable Wedding Alliance exists, and why our accreditation process is assessed and independently verified. When a couple sees accreditation, they are not taking a business’s word for its claims. They are taking ours, and ours is backed by assessment. For any business deciding between two similar suppliers, that third-party endorsement is what converts good intentions into bookings.
Third, be honest about the journey. No business has finished the work of sustainability, and couples do not expect you to have. They expect honesty about where you are, what you are working on, and what is next. The businesses that communicate this way build something rarer than praise. They build trust, and trust is what gets recommended.
The opportunity in front of us
There is a version of this where the responsibility conversation feels like a burden, another demand on businesses already stretched by rising costs and unpredictable weather. But I would frame it differently. The research shows an audience that wants businesses to lead, that rewards verified action with their custom, and that is asking us, clearly and in numbers we cannot ignore, to step forward.
Weddings are celebrations of the future. Nobody plans a wedding hoping the world their guests inherit is worse. Couples prioritising sustainable choices are not asking us for perfection. They are asking us to care visibly, act credibly, and speak honestly. The businesses that do will not just be doing the right thing. They will be the ones couples choose, recommend, and remember.
At the Sustainable Wedding Alliance, we are here to help you do the work, verify the work, and tell the story of the work. If you have been quietly getting on with it, now is the time to talk about it. If you have not known where to start, now is the time to start. Either way, you will not be doing it alone.
