Sustainability leaders in conversation
INVITE-ONLY COMMUNITY FOR IN-HOUSE SUSTAINABILITY LEADERS

Where sustainability leaders go to make progress

The connections that open doors. The knowledge that keeps you ahead. The peers who help you avoid the mistakes that cost organisations dearly. All in one community.

THE VALUE

Community is your competitive advantage

Most sustainability leaders carry the agenda alone. The weight of it is real, and most of the time there's nobody nearby who gets it. Leafr Leaders is where that changes.

Ask an expert

Direct access to people who are writing the rulebooks to seek clarification and get answers. e.g. SBTi, ISO, B Corp, Green Claims, Ecovadis.

Regular events

Monthly socials and an annual conference to put faces to names. Drinks, surfing, climbing, boules. The informal stuff that makes the formal stuff work better.

Resources & training

Training & courses

Validated peer recommendations

Tools & services recommended by peers that have actually used them.

A few simple values hold the community together

Closed doors, open chats

We all agree to have honest and open conversations in the knowledge that confidentially is of paramount importance.

Give before you take

The best communities run on generosity. Show up for others without keeping score and the whole room moves faster.

Practical, not preachy

The best conversations start with admitting what's hard. We're commercially minded, down to earth, and don't take ourselves too seriously.

Who's behind Leafr Leaders

Built by people who live this work

Nick and Gus had worked with hundreds of sustainability leaders at the UK's most well-known companies, and they kept hearing the same thing: "I'm in a small, siloed team with no support network". We started out running simple group dinners to connect those leaders, and the energy was incredible. Attendees asked for more. Leafr Leaders was born out of those dinners, and we've stuck true to the approach: intimate connections between like-minded leaders in sustainability. We've seen what separates the leaders who move fast from those who stall. Almost always, it comes down to who they have around them. Nick Valenzia and Gus Bartholomew Co-Founders of Leafr Leaders

Membership

Invite-only, and intimate by design

We believe the best communities act like the ultimate personal advisory board. Big enough to have diverse perspectives and small enough to be fully trusted.

FAQS

The things people usually ask

Who is Leafr Leaders for?
It's for senior, in-house sustainability and ESG leaders — heads of sustainability, ESG and impact, CSOs and equivalent. If you carry the agenda for your organisation, you'll be among peers.

We currently have industry working groups for Consumer, Food and Beverage, and Built Environment.
What exactly is a Canopy and how does it work?
A Canopy is a confidential peer group of six leaders at a similar level, meeting monthly throughout the year. Each session follows a structured format: one member brings a live challenge, the group asks clarifying questions, then shares relevant experience from their own careers. No advice-giving for the sake of it. No one talking book. Just honest, structured peer support from people who understand your context.

We form Canopies periodically for those that are interested in them, as they require careful consideration and training.
Is it really confidential?
Yes. We operate under strict confidentiality — no vendors, no audience, no minutes. It's the foundation everything else is built on.
What stops industry working groups becoming a compliance problem?
Good question, and one we've thought carefully about. Every working group operates under a clear participation framework that sets out what kinds of information can and can't be shared. Sessions are designed around professional development and shared challenges, not commercially sensitive information. We take this seriously so you don't have to worry about it.
What is the time commitment?
As much or as little as you like. Most members spend a couple of hours a month — a Canopy meeting, the odd forum post, and an event or call when it suits them.
Is this a corporate membership or a personal one?
Most members join with their company's support, but if that's not available we also welcome you to join as individuals investing in their own development. Leafr Leaders includes structured courses, expert-led sessions, and peer learning frameworks that map directly to professional development objectives. We can provide documentation to support an internal sign-off conversation if that's helpful. What matters is that you're here as a leader with something to contribute.
What does it cost?
Membership is an annual fee, which we'll talk through on your intro call once we know it's a fit. The perks, discounts and 0% commission consultant network are designed to more than cover it.
How do I join?
Request an invite, have a short conversation with us about fit, and if it's a match you're welcomed in. We're highly selective, and only open the door periodically.
