Membership

A Global Community for Future-Ready Sustainability Leaders.

TSC is an application-only membership for Senior Sustainability Leaders to navigate challenges, exchange insights and build career-defining connections.

What You Get From a Membership

Join likeminded sustainability leaders to compare notes, tackle challenges and share the things that move your company forward today.

Sustainability Leaders Only

All members lead sustainability in-house. We accept fewer than 15% of applicants to ensure the group stays senior, relevant, and focused.
No consultants, no vendors, no freelancers. One of the biggest benefits is who’s not in the room. This is a space for doers — not sellers.
Everyone speaks your language. Everyone is already working through complex topics like CSRD, Scope 3, and investor expectations — no need to explain the basics.

The visual evokes exclusivity and professionalism, likely targeting senior-level professionals or executives. There is no additional text or imagery apart from the stylized background, which features a soft lighting effect and modern design elements.

Personal Advisory Board

You’re matched with 12–15 peers based on role, company size, and experience — so discussions are tailored to your reality.
Think of it like your own circle of strategic sparring partners. A tight-knit group meeting for monthly board calls — built to help you pressure-test decisions, unpack challenges, and move faster.
Instead of another open forum you forget about. This is a group that shows up for you — in regular meetings, in a private thread between sessions, and in real life.

Most participants have their microphones muted, indicated by red microphone icons with a slash. Backgrounds vary: some are in office spaces, others have virtual backgrounds, including the Golden Gate Bridge and a forest scene. The Zoom interface is visible at the bottom, showing standard controls like audio, video, participants, chat, share, and breakout rooms.

Timely Roundtables

Live sessions focused on pressing issues. Whether it’s regulatory changes, decarbonization, or team structure — we address what’s current.
Designed for open dialogue. Sessions are held under Chatham House Rule to ensure confidentiality and candour.
Led by the TSC team or fellow members. Facilitated to keep things sharp, relevant, and grounded in real-world challenges.

Most participants have their microphones muted. On the left side, a sidebar titled "Next up" lists upcoming events with dates and titles: 16.05: "After the Omnibus — Making Smart Moves While Adjusting Plans" 19.06: "From Cost Center to Value Driver: (Re)positioning Sustainability at the Core" 21.07: "Scope 3: Driving Decarbonization with and through Suppliers" The design uses a dark purple gradient with white text, indicating a professional, sustainability-focused webinar series.

Member-led Show & Tells

Real examples from within the Circle. Members walk through projects they’ve led — sharing what worked, what didn’t, and what they’d do differently.
Q&A built in. Each session ends with open discussion, so you can ask questions, compare experiences, and exchange insights with our participants.
Steal what works. You leave with frameworks, internal language, and a full recording you can revisit anytime. Take what’s useful and adapt it for your org.
A visual storytelling graphic titled "Show & Tell" featuring a case study from a professional at a leading B2B electric appliances manufacturer. The main text reads: "How my team and I at a leading B2B electric appliances manufacturer achieved a 30% reduction in Downstream Emissions (Scope 3, Category 11)." A winding flowchart shows the journey with labeled steps: "Challenge," "Tried this," "Didn't work. What I learned," "Found a better way," and "What we achieved." The graphic includes a profile photo of the presenter and uses a purple color scheme with curved arrows connecting the steps.

Real-Time Support from Experts for Any Topic

Ask questions anytime. Whether you’re drafting a CSRD update, weighing an investment, or planning a strategy shift — post in one of the Executive Circle channels and get real-time input from experienced peers.
Get trusted recommendations. From consultants to carbon tools to internal comms decks — save time and money by tapping into what others already vetted.
High-quality feedback, no invoice. The kind of advice you'd normally pay for? Inside the Executive Circle, it's just a post away.
A screenshot of a LinkedIn post in a professional sustainability forum. The main post, titled "GHG emissions in LTI plans," is from a user seeking input on incorporating greenhouse gas emission KPIs into long-term incentive (LTI) plans. They ask about others’ experiences and KPI definitions, particularly whether renewable electricity instruments are excluded. A comment below from a Head of Sustainability explains how their company used CO2e/turnover reduction, including Scope 1, 2, and 3 emissions, in their incentive plan, and how it was received positively by management and the market. The post has 1 like and 11 comments.

Who Membership is for

This isn’t another event full of pitches. And it’s not a €20K network for generalists.
TSC is for in-house leaders doing the real work — navigating strategy, pressure, shifting regulations, and growing expectations.
Join likeminded sustainability leaders to compare notes, tackle challenges and share the things that move your company forward today.

A TSC membership is a good invest if:

You're a senior sustainability leader inside a company. TSC is for people who work in-house and own sustainability decisions. Most are Heads of, VPs, Global Managers — but what matters is ownership, not titles.
You want to connect with other strategic leaders. You’ll talk about aligning with the C-suite, influencing teams, and making sustainability work across — and for — the business. With people who’ve done it.
You’re looking for a trusted peer group. You’ll be matched with a group of 10–12 professionals in similar roles and org contexts. A private space to ask tough questions, test ideas, and get clear answers.
You want direct access to senior experts. Our sessions bring in CSOs and top execs who’ve led real sustainability transformations — from compliance to strategy to execution.
You value honest, practical feedback. Working on a board presentation, a supplier strategy, or climate target validation? This is where you get clarity from people who’ve been there and done the work.
You want fewer distractions and better conversations. No spam, no posturing, no performative LinkedIn threads. Just clear-headed discussions with sustainability leaders who are serious about impact.

You won't get value if:

You’re not a senior sustainability leader. This membership is built for professionals who own and drive sustainability at a strategic level.
You’re not in an in-house role. TSC is for sustainability leaders embedded inside companies — not consultants, advisors, or vendors.
You’re looking for open-ended networking. TSC isn’t another general sustainability community. It’s curated, intentional, and built to help you get clarity on real challenges — fast.
You just want content or templates. If you’re looking for off-the-shelf playbooks or reporting checklists, this isn’t the place. TSC is about leadership, peer insight, and strategic decision-making.
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's It Like to Be a TSC Member?

Don't Just Take Our Word for It—Hear from
Our Members Themselves!

Only Senior Leaders

We accept less than 15% of applicants. No vendors, no consultants — just senior sustainability leaders sharing openly what works and what doesn't.

No Selling

Strict no-solicitation policy. No cold DMs, no sales pitches in shared spaces. The Executive Circle runs on trust and candid peer exchange.

Chatham House Rule

Everything shared stays in the Community. Confidentiality is core — and most peer groups choose to sign NDAs to speak openly.

Built for Busy Leaders

It just takes 2 hours a month — and we schedule your peer sessions around your calendar, based on your preferences during onboarding.

Fits Into Your Workflow

Yes, TSC runs on a platform — but you’ll only get what matters, right in your inbox. No spam, no daily logins, no overwhelm.

No Theory. Real Impact.

This isn’t a shallow course or content feed. It’s where senior leaders solve real problems, fast — and walk away with smarter decisions.

Why Join The Sustainability Circle?

Fair question. €1.490/year is an investment — but if you’re here, you’re serious about leading sustainability at a higher level. And the truth is: one sharp insight, one honest exchange, one intro, or one shortcut can easily save you €20K
— or weeks of wasted time.
Your CEO wants short-term wins — and you’re out of ideas. You hop on a call with a peer who's been there. They share how they reframed the conversation. You leave with new language and a few quick wins.
Market or regulatory changes made your strategy obsolete. You need to pivot fast? Join a roundtable with others in the same boat. They share what they’re doing — and what’s not worth stressing about. Together, you shape a new plan to lead change in your company.
You’re about to sign a $50k contract with a consultancy.
Before you do, you check in with the Executive Circle. Others share how they scoped it tighter — and got better results. You renegotiate, save $20k, and earn serious credibility with your CFO.
You’re evaluating carbon accounting platforms and lost in the requirements jungle. You ask who others picked and why. They share honest feedback — what actually worked in practice — so you can choose with confidence.
You need to negotiate your compensation. You wonder what market rates look like, how others split salary and bonus, and what arguments actually work. You connect with members who’ve done it recently — and walk into your conversation more prepared (and walk out with a better offer).
You just got out of a rough leadership meeting. You show up to your peer-group call, vent a little, and hear “been there.” You leave with three ideas for how to reframe the issue — and show up stronger next time.
You’re unsure about your next career move. You wonder if you’re having the impact you could. You’re torn: stay or move on? Double down or pivot to something new? Invest in skills—or relationships? Get feedback form peers who’ve faced the same crossroads, and leave with clarity on your next step.

How much time do i need to allocate?

2 hours a month are the baseline that will cover your monthly Personal Board of Advisor Session including the preparation. Beyond that you can follow the mantra: The more you put in, the more you get out.

How long is the TSC Membership? Will it fit my schedule?

The membership is 12 month long and starts with introductory sessions in Week 1. The main community-wide live sessions run on Thursdays and Fridays (Europe time). Your Personal Board of Advisor Sessions are based on your individual schedule.

How can i get the membership reimbursed by my employer?

TSC membership benefits both you and your company. The skills you acquire at TSC enhance your capacity to deliver results that advance the business. For this reason, many of our members receive reimbursement from their employers through their company's Learning & Development (L&D) budget.

  • Actionable Advice: Engage with peers to avoid costly mistakes, reduce blind spots, and gain fresh perspectives. Leaders benefit from eye-level interactions rather than content-based learning alone.
  • Career-Making Support System: No matter the problem, one of your peers has faced it. You gain allies for every challenge, ensuring you never have to make critical decisions alone.

By leveraging your L&D budget for TSC, you invest in a support network that accelerates your professional growth and enhances your decision-making process. This practical, peer-driven approach offers immediate benefits to your role and organization—because there are things that can't be learned in a course or read in a book.

What if I don't like the TSC Membership?

If you’re less than 3 weeks in, we’ll refund you 100%. Our only request is that you give us feedback so we can make improvements.

What can I expect from the application process?

The initial step in joining us is to fill out an application. If your application aligns with our membership criteria, you can expect to hear from us within 2 working days to arrange a 20-minute virtual interview.
