How much time does the platform take?

Thirty seconds a day. Nothing more. Sustainers is deliberately designed not to create an additional burden. Onboarding takes no more than two minutes, and the platform is so intuitive that every employee can start using it right away. No training, no separate time blocks, no learning curve. In those thirty seconds, an employee records their action for the day and sees the impact they have made. That is all. It connects to what people are already doing, instead of adding something on top. Getting started is easy too: You provide one internal point of contact and the team captains We take care of the technical setup, the content, and the guidance No IT project, no large-scale rollout You can start organization-wide or with just one department.

How does Sustainers handle our data?

We store as little as possible. Only what is truly necessary: name, which can also be an alias, and email address. No IP addresses, no device data, and no unnecessary personal data. Your data is stored in a secure environment that only our fixed core team can access. No external parties, no contractors. Technically, we do everything we can to ensure this is handled properly: Encrypted connections, TLS 1.2 or higher Cloudflare protection on our endpoints Automated security scans via GitLab Annual external penetration test by security company Below0Day All recommendations from those tests are implemented immediately. And if you ever stop using Sustainers, the data is fully deleted — or exported in advance upon request.

Who is this suitable for?

Sustainers is not a standalone sustainability initiative. It is an extension of the sustainability manager or the team that is already working on sustainability. The platform is designed for organizations that want to take the next step: not just talking about sustainability, but making it truly land in the daily operation, with all employees. What it delivers for the sustainability manager: Control and overview of what is happening across the organization Scalability, without everything depending on one person Insight into where the greatest impact can be achieved For the organization as a whole: Employees gain a concrete perspective for action Sustainability stops being a project owned by one department and becomes something everyone contributes to Some organizations already have a sustainability vision. Others are still building one. Both can get started with Sustainers — as long as there is a real willingness to take meaningful steps.

What does it cost and how does it work?

We do not display a fixed price on the website, and that is intentional. Together, we determine the pricing based on the size of the organization and the type of content that will be most valuable for your team. This ensures the proposal matches the value it delivers — a partnership that works for both sides. We work with annual contracts. Not to lock people in, but because we know that this kind of change takes time. Embedding sustainability within an organization cannot be done in just a few weeks. An annual contract creates the space to do it properly — without time pressure becoming the wrong driving factor. Curious what a collaboration could mean for your organization? Get in touch and we would be happy to think along with you, with no obligation. - No fixed pricing — tailored to your organization - Based on company size and valuable content needs - Focused on long-term impact through annual partnerships - Built to create sustainable change at a realistic pace

Is the content also relevant for my employees?

Yes, and that is exactly what Sustainers focuses on: ensuring that every employee receives challenges through which they can genuinely make an impact. The platform is fully modular. For each role, department, or team, you can switch relevant topics on or off. A purchaser sees different challenges than a sales advisor. A field technician receives different actions than a colleague working in the office. This way, everyone can participate in the area where they can make a difference. We work on two levels: Work processes and roles Purchasing — which choices make a difference in the supply chain? Sales and advisory conversations — how do you bring sustainability into the customer conversation? Consultancy — how does sustainability become part of your advice? Nursing — how can I reduce the use of materials or medication? Sector-specific Construction — material choices, circular construction, logistics Distribution — transport, packaging, supply chain responsibility Healthcare — reducing or using medical devices more efficiently, following the guidelines of Samen de Zorg Vergroenen General practitioners and pharmacists — challenges based on the QuickScan for sustainable prescribing Accessible to everyone Topics that are recognizable for every employee: commuting, food, office energy use, and digital footprint. These remain available as a foundation, so colleagues without a direct role-specific connection can also participate. Our belief: the more recognizable the content is, the greater the chance that someone will actually act on it. We have more than 150 specific challenges in our library and always tailor the content to the organization.

What concrete benefits does it bring us?

The platform is built on learning by doing. Employees do not learn about sustainability by reading about it, but by actually doing it — small, practical challenges that fit directly into their daily work. We deliberately choose challenges that also create financial value. Reducing waste, lowering the use of raw materials, approaching conversations or processes differently — these are actions that are both sustainable and cost-saving. Why this is smart: - Sustainability becomes easier for managers to justify - Participation becomes more attractive for employees - You engage a broad majority, not just the early green adopters The financial benefit does not always have to take center stage. But when organizations are given the choice, they almost always prefer it. Because it lowers the barrier to participation and increases support across the organization.

Last weekend I thoroughly enjoyed reading an article by Michiel van der Geest in de Volkskrant about nurses leading the way in green healthcare. Nicole Hunfeld shares her 'eye-opener' during the COVID pandemic — the starting point of her mission to radically green the healthcare sector together with nurses.

It's great to read that so much is happening. Countless initiatives have now taken root in a sector that is already working incredibly hard, and that gives hope.

Why healthcare can be such a game changer

Nicole calls it the 'triple benefit': going green means lower emissions, lower costs, and often less time. That combination is incredibly powerful. And that's exactly what we at Sustainers have been working on over the past few months together with a major health insurer — weaving sustainability together with the financial added value for organizations.

Across many sectors we see similar cases where greening goes hand in hand with efficiency and cost reduction, as long as you approach it the right way. Together with De Groene Huisarts, we are developing data for GPs to make that impact visible there too. Another part of healthcare that is working flat out and creaking under the pressure of climate change — but one that is willing to take action. Concretely and practically.

The opportunity in healthcare

The article makes it painfully clear that healthcare has a strong throwaway culture. It is certainly not the only sector. Acknowledging that is step one. A lot of material is discarded unnecessarily or replaced too quickly. Products are not reused even when it would be perfectly possible. And that is where the opportunity lies.

By being smarter about materials, throwing less away, and reusing responsibly more often, something remarkable happens:

Costs go down
Waste decreases
CO₂ emissions fall

And perhaps most importantly of all in healthcare: it saves time and reduces workload.

Sustainability as a lever

Healthcare shows how powerful sustainability can be when you approach it well. Not as an extra burden or a box to tick, but as a solution. Better for the environment. Easier in practice. Cheaper to implement.
