The "Unfair Advantage"
for European Sustainability Leaders.

You could spent €25.000+ and 3 months hiring a consultant to tell you what might work.

OR...you can invest €1.490 to join a confidential Circle of 8 to 10 senior leaders at your level who share what has actually worked inside their organisations.

THE CHALLENGE IN 2026

Mandate reduced. Budget cut.
Still expected to deliver.

You are expected to drive transformation across your organisation while navigating P&L pressure, shifting priorities, and limited internal support. With little precedent, you must decide where to focus next while avoiding costly mistakes. Who do you turn to pressure-test those decisions before presenting them internally?
This is not a personal weakness. It is structural. The higher you climb, the fewer peers you have to speak openly with or test decisions against. That’s why senior leaders rely on trusted peers.

THE SOLUTION

Join a Confidential Circle of Peers at Your Level to Pressure-Test Decisions Together

Matched peer group from The Sustainability Circle's Personal Board of Advisors program, featuring diverse sustainability leaders connecting through their shared expertise and collaborative insights to tackle challenges together.
1. Join a Carefully Matched Circle

You are placed in a confidential group of 8–10 senior in-house leaders matched by seniority, responsibility, budget scope, and organisational complexity.

2. Solve Your Challenges With Peers

You bring a challenge your currently facing to the monthly session. Your peers share what worked for them in their organization and what didn’t.

3. Apply What Works in Your Role

You avoid costly mistakes and can confidently decide what to do next. If questions come up during implementation, you just turn to your group again.

WHAT IT'S LIKE TO BE PART OF A CIRCLE?

What a Circle Can Do for You

Only Senior Leaders

Everyone in your Circle holds responsibility for sustainability at your level. You speak with peers who deal with similar decisions and pressures.

No Selling

Selling at TSC is strictly prohibited. Nobody is there to pitch anything. People talk openly about their work and the challenges they’re dealing with.

Chatham House Rule

Everything shared in the Circle stays there. People can speak openly without worrying it leaves the room.

Built for Busy Leaders

Monthly sessions last two hours and are scheduled for the full year in advance. It’s a small but high ROI and  predictable time commitment.

Powerful Relationships

You build strong, trusted relationships with senior sustainability leaders you can speak openly with and rely on over time.

Support for Career Moves

Get support from peers in similar roles when you take on bigger responsibilities, negotiate your role, or consider your next step.

WE ARE NOT FOR EVERYONE

Who TSC Is For. And Who It Is Not.

TSC Is a Strong Fit If:

You're a sustainability leader inside a company. TSC is for people who work in-house and own sustainability decisions. Most are Heads of, VPs, CSOs.
You’re looking for a trusted peer group. You’ll be matched with a group of 8-10 peers in similar roles to work on your challenges and pressure test decisions.
You want to connect with other strategic leaders. You’ll talk about aligning with the C-suite, influencing teams, and making sustainability work.
You want fewer distractions and better conversations. No spam, no posturing, no performative LinkedIn threads. Just clear-headed discussions true peers.

TSC Is Not a Fit If:

You’re not in an in-house senior role. TSC is for sustainability leaders inside companies, not consultants, advisors, or vendors.
You’re looking for open-ended networking. TSC isn’t another loose sustainability network. We convene in thight-knit peers groups to work!
You just want content or templates. If you’re looking for off-the-shelf playbooks or reporting checklists, this isn’t the place.
You prefer passive learning over active engagement. You don’t have to be loud, but you do need to participate. If you’re just looking to lurk, this isn’t a fit.

What You Can Discuss With Your Circle

Almost anything! You team up with people in similar roles who have no work ties to you. That makes it easy to be completely honest and get first-hand feedback from people who have been there themselves.
Challenges Members Discussed With Their Circles:
A CEO wanted short-term wins and the member was out of ideas. The Circle discussed what worked in similar situations and how to reframe the conversation. The member left with new language and quick wins.
A member was about to sign a $50k materiality assessment contract. The Circle compared to their providers, scopes and costs. The member renegotiated and saved $20k.
Stripped-down regulation disrupted a member’s strategy. The Circle asked tough questions and helped the member regain clarity. The member left with a clear next step.
A member was facing an upcoming performance review and wanted to negotiate compensation. The Circle shared benchmarks and what worked in similar negotiations. The member secured a 15% raise.
A member was evaluating carbon accounting platforms and was overwhelmed by options. The Circle shared what worked in practice from them and what to avoid.

FAQs

How much time does it require?

Very little. We know you are busy. It is just one 2-hour call with your Circle group every months. No homework, no prep work. Just show up and solve problems and get support.

Who are the other members?

We manually vet every applicant. You will only be matched with Senior Sustainability Leaders (CSOs, Heads of, Directors, VPs) from non-competing companies in Europe. No consultants or sales vendors are allowed.

What if i can't attend a session?

Sessions are recorded for internal use, but the real value is the live discussion. Since the schedule is set 3 months in advance, most leaders find it easy to prioritize.


What if I don't like my Circle?

Trust the process. Circles are matched based on mandate, team structure, industry complexity, and current challenges. Often the peers you expect the least from bring the most valuable perspective. If it’s still not a fit, we’ll find a better group for you.
