People Behind the Mark 👋

We asked Millie Hocking , our Senior Account Manager the one thing she wished more businesses understood about supply chain emissions.

Not that Scope 3 matters, everyone knows that by now. It’s usually the vast majority of a company’s footprint, and most sustainability teams have known it for years.

The gap is the doing. And the reason it’s hard is rarely willpower, it’s data. Your emissions are sitting with suppliers who often haven’t measured their own, so you’re building a picture from partial numbers and spend-based estimates that can quietly flatter your progress.

Which is why the businesses moving fastest aren’t the ones who understand the theory. They’re the ones who’ve done the unglamorous work of actually getting the numbers.

That’s the step we help with.

London Climate Action Week is coming up.

A note from our founder, Steve Malkin, on why moments like this matter.

Bringing people together can be powerful, but only when there is a clear purpose behind it. For Steve, the value of LCAW is not in talking for talkings sake. It is in mobilising, learning quickly from eachother and working out how we do more, faster.

Planet Mark will be in London throughout the week, looking for the conversations that lead somewhere practical.

If you’re attending and want to meet the team, or need support with something action focused, send us a note.

This , the theme is Give To Gain, a global call to advance gender equality through generosity, advocacy and support.

At Planet Mark, we’re looking at it through our own lens: giving back to the planet. Our day-to-day work helps businesses measure their impact, improve over time, and take responsibility for their footprint.

Across our team, that commitment is personal.

For our Managing Director, Avital Johanan, it’s rooted in responsibility and collective impact:

“The collective impact of our members is my daily motivation… The choices we make impact businesses and their opportunity to transform and meet the needs of a sustainable future.”

For our Senior Engagement Manager, Hannah Dean-Wood, it’s much closer to home:

“Growing up in the countryside with frogs and fireflies as my daily companions made nature feel like my first set of siblings. Protecting the planet now feels personal rather than abstract, more like caring for a family member, and that perspective keeps my work at Planet Mark grounded in gratitude, responsibility, and a childlike sense of curiosity and joy.”

And those are just two perspectives.

In our latest blog, more of the women behind Planet Mark share what giving back means to them, and how it shapes the way they work every day.

If you’re reflecting on what you choose to give, your time, your voice, your leadership, their stories offer a thoughtful place to start.

🎥 Live from Cleaning

We’re here today at one of our Member Regular Cleaning’s client sites, filming a new case study that highlights how they’re putting sustainability into practice within the cleaning industry, showing how real change happens through everyday action.

It’s inspiring to see a business in such a hands-on sector leading by example and proving that .

A huge thank you to the Regular Cleaning team for their warm welcome, and to our Planet Mark crew, for bringing it all to life.

We’re thrilled to announce our partnership with , helping organisations accelerate their transition to low-carbon transport.

Almost a year after hosting our event together, this collaboration marks the next step in supporting businesses and employees to make measurable climate impact.

Octopus EV enables businesses to help employees save up to 40 % on an electric car through a no-cost, minimal-admin salary-sacrifice scheme, joining 7,500 + companies already on board.

🌍 Switching to an electric vehicle can save 1.5 million grams of CO₂ every year, the same as four return flights from London to Barcelona.

For Planet Mark Members, that means reducing emissions, supporting their journey to net zero, and empowering teams to lead by example.

Employees also benefit from £500 off low-carbon tech and access to green energy tariffs like Intelligent Octopus Go, empowering individuals and organisations to take measurable steps toward a more sustainable future.

Together, we’re turning sustainability ambition into measurable impact.

Yesterday, the Planet Mark team came together for our Q4 Strategy Day, an afternoon of reflection, collaboration and forward thinking as we head into the final stretch of the year.
The day was all about connection and collective thinking, from discussing our understanding of value chains to brainstorming around Planet Mark’s strategic pillars and themes for Q4. Our open colleague panel gave us a glimpse into a day in the life across different teams, a great reminder of how each role contributes to our shared purpose, and a chance to exchange honest reflections and ideas for the year ahead.

We also took time to pause and reflect on what change really means, not just as a shift in direction, but as a transition we each move through. From endings to new beginnings, it’s the space in between, ✨the neutral zone✨, where growth and transformation take root. 🌿

And, in true Planet Mark spirit, we finished with two truths and a lie (work edition), let’s just say we learned a few things we didn’t expect. 😄

A huge thank you to everyone who brought curiosity, openness and good energy to the day. It’s this collective reflection and collaboration that keeps Planet Mark moving forward with purpose.

Yesterday, some of our Planet Mark team attended the Great Green Balloon Debate, hosted by our Partner and sponsored by Carefree, with Sarah Duncan and Grace Greensitt leading the event.

Our Partnerships Manager, James Shorey, was a finalist in this year’s debate and came third place🎈, joining a fantastic line-up of sustainability leaders tackling one big question: Who’s going to save the planet?

James Shorey took to the stage to present “Everyone, Everywhere”, a powerful reminder that:

“We face hundreds of challenges and thousands of impacts, and that’s why every person’s actions matter. It’s about being an urgent optimist.”

💬 The key takeaway:
Collaboration is our greatest tool. Every solution matters, and only together can we turn optimism into meaningful climate action.

🎥 Live from The Langham Estate

We’re on site filming a case study that showcases the incredible steps The Langham Estate is taking on their journey to net zero.

Yesterday, some of our Planet Mark team attended the Energy Innovation Agency’s Accelerating Sustainability conference in Manchester, where our Founder, Steve Malkin, spoke about the importance of collaboration in driving credible climate action.

The day was a powerful reminder that partnership is key to scaling real-world solutions for net zero. From insightful keynotes to practical case studies, discussions explored how quality data underpins credible action, and how, for many organisations, the greatest challenge lies in overcoming the fear of making the wrong decision when adopting new energy technologies.

It was particularly inspiring to hear about the innovative pilot projects being rolled out in Norway by Skagerak, demonstrating what’s possible when technology is tested for both deployability and scalability.

A huge thank-you to the Energy Innovation Agency for bringing together such an ambitious community of changemakers. We’re proud to be a partner in accelerating sustainability across Greater Manchester and beyond. 🌍🚀
