You know you want to move on sustainability. Knowing how is the hard part.

You know it matters, but don't know where to start

You're overwhelmed by regulations, requirements and certifications

You want to communicate your impact without greenwashing

Your teams need to be activated and empowered

You have a goal in mind, but don't have the right knowledge or manpower

You want data-driven insights and use them for good
Six things we're genuinely good at
All services
Impact measurement
GHG accounting, life cycle analysis, KPI dashboards and reduction scenarios — models your team can run themselves next year.

Communication & storytelling
Reports, brand narrative and content that's evidence-based and greenwash-free. No clichés, no green wallpaper.

Strategy & roadmap
Materiality, target setting, SBTi alignment and a roadmap built to survive contact with your actual business.

Practical implementation
The part other consultants leave you with. Pilots, supplier engagement, process change — done alongside your team.

Data-driven tools
Workshops, mentoring and critical review, so you build capability in-house and need us less over time.

B Corp certification
End-to-end guidance through certification, including the new 2025 standards. You don't have to reinvent the wheel.
We don't consult. We do.
Plenty of consultants write the strategy. We're the ones still there when the supplier says no and the data doesn't add up.
We start with a straight answer
We meet, look at where you actually are, and tell you honestly what's worth doing first — and what isn't.
We embed
One or two days a week inside your team. In your Slack, in your meetings, owning outcomes rather than recommending them.
We build capability as we go
Your people learn the work while we do it. The goal is that you eventually need us less.
We scale to what you need
Busy reporting season? Scale up. Quiet quarter? Scale down. No employer obligations either way.
We tend to stay a while
Most clients started with one project and are still with us years later. Here's the whole relationship, not a list of jobs.
Client stories are being added.
What clients say
We spent over two years trying to get B Corp certified on our own — then New Alchemists jumped in and made it happen.
Four people who will actually be in your Slack
No account manager layer, no junior hand-off. You meet us, you work with us.

We're looking for people who like sustainability work that actually gets finished — embedded in client teams, in Amsterdam, with real ownership.

The things people ask first
We work on a hour-rate basis, and only invoice hours actually worked. Rather put us on retainer? Also possible. A B Corp trajectory usually runs 6–9 months, a greenhouse gas analysis or LCA around 1-3 months. We'll give you an honest estimate after the first conversation — including telling you if you don't need us yet.
At company level using the Greenhouse Gas Protocol, or at product level using life cycle assessment. We build the model so your team can run it themselves next year.
Usually not. Companies from about 10 employees benefit from getting the foundations right early — far cheaper than retrofitting later. If we think you genuinely are too early, we'll say so.
A certification from non-profit B Lab for companies meeting high standards of social and environmental performance, accountability and transparency. It looks at your impact on workers, community, customers and the planet.
You keep everything — models, templates, dashboards, documentation — and your team knows how to run it. Most clients keep us on for the annual cycle, but by choice rather than dependency.
Not sure where to start?
Most companies don't need everything at once. In a free 30-minute call we'll help you work out what to prioritise.
