In summary: June 5th is World Environment Day. Today, thousands of brands will publish the same post with the same nature photo and the same message about the planet. Fluye also has a post. But this one includes the real numbers of what we do, even if they are small. Especially because they are small.
World Environment Day 2026: what we do while others post messages
Today is June 5th. World Environment Day, established by the UN in 1972 after the Stockholm Conference. More than fifty years of annual commemoration, which also means more than fifty years of brands writing posts about how much they love the planet.
Fluye also has today's post. What we try to do is make sure this one has something most don't: the real numbers of what we actually do, with its limitations and without embellishment. Not because we are better than anyone else. Because we believe it is the only honest way to participate in this conversation.
What happens on June 5th in the marketing world
You don't have to be cynical to recognize the pattern. World Environment Day triggers a fairly predictable process in many companies: an allusive content is published, a hashtag is added, a commitment to sustainability is mentioned, and by June 6th, the routine returns exactly to where it was.
This has a name: greenwashing. Not always intentional, not always conscious, but very widespread. A declaration of values without data behind it, without verifiable actions, without any way for the reader to check if it's real.
If you want to better understand where the line is between honest sustainability communication and greenwashing, we analyze it with concrete examples in this article. It's not about good or bad intentions. It's about what you can prove.
What Fluye does (and the numbers to prove it)
Fluye is a brand of thermal bottles. We sell a product made of 304 stainless steel, double-walled vacuum insulated, which keeps water cold for 24 hours and coffee hot for 12. We didn't invent the reusable bottle, nor were we the first in the European market. We are one among many.
The difference we try to maintain is this: each bottle Fluye sells finances 5.4 liters per month of drinking water for communities in Peru that still do not have access to it.
It's not a promise. It's a concrete mechanism. We work with the NGO Los Sin Agua on fog catcher projects, installations that capture fog and convert it into drinking water in areas of the Peruvian coast where it rains very little but fog is abundant. Each fog catcher provides approximately 300 liters of water per day to the community where it is installed.
If you want to understand how the technology works and where these projects are located, here is the full article about fog catchers.
The real numbers, with their limits
At Fluye, we publish impact numbers. We don't idealize them. When they are small, we publish them anyway. When they haven't grown as much as we expected, we say that too.
We continue with a project that is progressing slowly and sometimes not as fast as we would like. We don't have the resources of a big brand. We operate from Barcelona with a small team and with projects that depend on coordination with an NGO in Peru.
What we do have is transparency about what is happening and what is not. Photos with dates of active projects. Quarterly updated numbers. And the honesty to say that we are trying, not that we have already succeeded.
The updated data on liters financed, active projects, and the status of fog catchers are on Fluye's impact page. Not in a downloadable PDF that no one opens. On the website, visible, with an update date.
Why we buy plastic bottles even though we know we shouldn't
World Environment Day is also a good time to talk about something most sustainable brands avoid mentioning: the contradictions of conscious consumption.
We know that single-use plastic is a problem. We've known it for decades. UNEP has been documenting for years that we produce over 400 million tons of plastic annually, a huge portion of which are single-use containers. And we keep buying plastic water bottles.
Not because we are irresponsible. But because the alternative has friction: you have to remember to bring the bottle, you have to have a bottle, it has to be clean, it has to be where you need it when you need it. When none of that is resolved, the plastic bottle is easier.
The most honest selling point Fluye has is not its environmental impact. It's that if you carry a bottle you like, that keeps water cold, that isn't too heavy, and that you don't need to replace every year, the probability of you using it every day is high. And if you use it every day, you don't need the plastic bottle.
A Fluye bottle has the potential to prevent more than 150 plastic bottles a year if it replaces the usual consumption of bottled water. This calculation assumes that you previously bought bottled water frequently and now you don't. The actual impact varies depending on your previous habits. That's why we always state it with context, not as an absolute fact.
What we ask you not to do today
We don't ask you to share this article with a hashtag about the planet. We don't ask you to "join the movement" or "be part of the change." Those phrases no longer mean anything, and we know it.
What we do ask, if you've read this far, is that you check the numbers. That you go to the impact page and see what's really there. If something doesn't fit or isn't clear, ask us. We prefer an uncomfortable conversation over applause we haven't earned.

Another year. We are still here.
