What makes you different from other sustainability consultants?

I come from the fashion industry itself. I worked as a designer, product developer and CSR manager before I became a consultant, and I still work as sustainability strategist in the team at Kuyichi. So I know how decisions get made in product, buying and marketing, and I set up strategies and claims processes that fit those timelines and the everyday reality of a fashion company. I don't write strategies or reports that change nothing, and I won't help a brand look further along than it is. I will show you where you stand and which steps come next.

Do I need external support if I already have a sustainability team?

Your team knows your company best and handles the daily work: data, suppliers, questions from customers. Every team also has topics where deeper expertise helps, such as green claims, due diligence or reporting. For those I bring the knowledge, the tools and the training, so your team comes out stronger in its own role.

Can small brands afford sustainability consulting?

Yes. I work with small and large brands, and not every brand needs a full project. Sometimes one strategy session or a team training gives you enough direction to move forward. Tell me what you need, and we will find a form that fits your budget.

Do you work with clients outside Europe?

Yes. Most of my clients sell in Europe or supply European brands. I specialise in EU rules and what European customers expect, so I help companies outside the EU understand what their European buyers and regulators ask of them.

SUSTAINABILITY CONSULTANCY FOR FASHION AND LIFESTYLE BRANDS

I help fashion and lifestyle brands do what they say and say what they do.

Book a discovery call

I'm Nynke Eggen, and The Sustainability Club is my sustainability consultancy in Amsterdam. I help fashion, lifestyle and consumer brands with sustainability strategy, green claims, due diligence, reporting and training. You work directly with me, from the first call to the final presentation.

THERE IS A FUTURE HERO IN EVERYONE.

Most people want to do the right thing. What they miss is clarity: which rules apply, where the impact is, what to do first. I started The Sustainability Club to give that clarity, so you and your team can make the changes yourselves.

What I do

Sustainability strategy

A sustainability strategy and roadmap that bring together what the law asks of you and what you want to achieve as a brand. You know where your impact is, what to do first and why, and your team has a plan it can work with.

Green claims

I help you make claims you can stand behind, by making sure the impact behind them is real. I check your claims against EmpCo and other rules, write your green claims guide or playbook, and set up the system so marketing, product and sales know what they can say and how to substantiate it. You can talk about your progress with confidence.

Due diligence

Find and reduce the human rights and environmental risks and impacts in your supply chain, based on the OECD due diligence guidance. You know where the risks are, what you are doing about them, and what to answer when a customer or regulator asks.

Sustainability reporting

A clear sustainability report, following the GRI Standards or in your own format. Your report is where accountability starts. I help you use it to find your biggest impacts and act on them, year after year. Or I set up the reporting framework, so your team knows what to report, how, and who owns which data.

Training

Training for your team, in-company or at an event, on green claims, strategy, reporting and due diligence. I break complex topics down into steps that are easy to understand and to act on, for the people who work on this day to day.

Interim

I join your team as sustainability strategist for a set period, from half a day a week: to set up your strategy or systems, to cover a leave, or to keep the work going while you decide on a permanent role.

Rules, frameworks and reports are more than paperwork. Used well, they show you exactly where to improve.

How I work

Let's talk

Make it doable

Most brands know what they want to do. The hard part is the how: which rules apply, what you can prove, and who does the work next to their existing job. I make the plan fit the way your organisation already runs.

Start with the product

For a brand that makes products, most of the impact is in the product: what it is made of, where and how. That is where I look first, because that is where the biggest reductions are. Communicating about it comes after.

Go and look

I have walked hemp fields in China with a client to understand a supply chain that barely exists on paper. You can't ask a chain like that for a certificate overnight, so we started with relationships. My advice starts from the situation as it is.

Use the law as a tool

I help you understand what the law requires. Meeting it often reduces your impact already. Then we choose the extra step that matters most for your brand, and I help you say it clearly, with the proof in order.
