THE CHALLENGE

Driving the transition alone?

But who do you turn to when you’re not sure what will work?
Compliance alone no longer carries decisions through. Sustainability leaders are expected to deliver business impact and long-term change in organisations that shift priorities and push back. The challenge moves from expertise to judgement.

With little precedent, leaders must decide where to focus limited resources, which approaches will land internally, and how far to push. Doing this in isolation slows progress and risks impact and credibility.
The cost of working in isolation
Weeks are wasted on groundwork others have already done.
No one to stress-test decisions before they go to leadership.
Initiatives stall, get watered down, or never get approved.

WHAT TO DO INSTEAD

Join a Circle of Peers Who Have Already Been Where You Are

How Circles work.

TSC Circles are confidential groups of 10–12 senior in-house leaders, matched by responsibility, budget scope, and organisational complexity.
You bring a challenge to your group. Your Circle shares the solutions they implemented, the frameworks they used, and the mistakes they made so you don't have to.
100% Practitioner Experience
Strict Confidentiality
Curated for Seniority
60 Minutes per Month

Not advice. But what actually worked.

BEFORE
"Leadership supports decarbonisation in principle, but won’t commit to investment."
AFTER (60 MIN CIRCLE SESSION)
"This is the internal carbon price model we used to prioritise abatement options. Run it alongside capex planning, not sustainability reporting. That shifted the discussion from values to financial trade-offs.”
THE INNER CIRCLE

TSC is More Than Your Peer Group

Peers Who Understand You.

Finally, a room to drop the corporate mask. Connect with peers across Europe who speak your language, understand the pressure, and have your back.

Access, not networking.

Build deep, trusted bonds with Europe’s top sustainability leaders who will elevate your thinking and welcome you into a trusted inner circle of support.

10x Your Career.

Leverage direct access to top decision makers to absorb the mindsets, decisions, and connections that accelerate your path to the C-suite.

FAQs

How much time does it require?

Very little. We know you are busy. It is just one 60-minute call every months. No homework, no prep work. Just show up and solve problems.


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.
