What users say
Participating in the Sustainers challenge, gives us the chance to learn about our own consumption behaviours to change habits to make a tangible difference today and into the future. The IPCC have published a new report that shows that Having the right policies, infrastructure and technology in place to enable changes to our lifestyles and behaviour can result in a 40-70% reduction in greenhouse gas emissions by 2050. This offers significant untapped potential. The evidence also shows that these lifestyle changes can improve our health and wellbeing. What’s good for the planet is good for us. Let’s be a part of the change we want to see.
Good intentions quickly disappear in the busyness of the day. This app keeps sustainability simple and visible. The game element makes it fun and ensures it truly becomes a team activity.
"Starting small and staying consistent — supported by the Sustainers app — helped us save 400,000 kg of CO₂, and genuinely changed my personal behavior for good."
“What an eye-opener—an app that gives you insight into the impact of your own daily actions. Simple, effective, and inspiring—it helps you make yourself, your team, and your company more sustainable within your own sphere of influence! No more excuses—just take action.”
“The sustainable transition is ultimately about people and their behavior. Making their own impact visible can be the difference between taking action and not taking action. Sustainers is fantastic at driving this behavioral change in a simple and engaging way.”
Through Sustainers' challenges, Klaverblad has measurably reduced CO₂ at both the organizational and individual level — a meaningful step toward net zero.
"Healthcare institutions are full of green ideas — Sustainers finally gave us the platform to bring those ideas together and turn them into real, rewarded action."
By deleting 60,000 emails alone, I saved an estimated 1,400 kg of CO₂ — Sustainers made our digital footprint visible and gave us concrete steps to reduce it.
Sustainers is one of the most effective tools I've seen for engaging employees in reducing a company's carbon footprint — impactful, practical, and genuinely motivating.
Frequently
asked
questions
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.
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.
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.
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
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.
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.
