How do you communicate sustainability when the solution is technical, the audience is global and trust matters as much as the message?

In this episode of the Sustainability Review Podcast, Matthew Campelli is joined by Andreas Mündel, SVP of Strategy and Operations at DHL Group.

Together, they explore how DHL frames sustainability not only as an internal responsibility, but as a customer solution and competitive advantage. From GoGreen Plus to sustainable aviation fuel and electric fleets, the conversation looks at how decarbonisation can become part of the value proposition in logistics.

Andreas also shares how DHL balances simplicity with technical accuracy – particularly when communicating complex concepts like book and claim – and why external standards, NGO collaboration and auditable data are essential for building trust.

The episode also looks inside the organisation, exploring how DHL embeds sustainability through its “four bottom lines”, internal training, performance targets and clear KPIs.

Finally, Andreas reflects on the future of sustainability communication: more regulated, more evidence-based and more challenging, but ultimately better equipped to separate real progress from empty claims.

How do you communicate sustainability in a way that actually reaches people – across thousands of hotels, brands and audiences?

In this episode of Sustainability Review Podcast, Matthew Campelli is joined by Marjorie Pittet, VP of Sustainable Operations at Accor.

Together, they explore how sustainability communication works at scale in a global hospitality business – and why experience, not messaging, is often the most powerful way to engage people. From the guest journey to internal teams, the conversation looks at how sustainability can be embedded into everyday interactions, rather than treated as a separate narrative.

Marjorie also shares how Accor balances consistency with flexibility through a shared framework – what she describes as “freedom within a framework” – and how tailoring messages for different audiences, from investors to hotel staff, is key to driving action.

Finally, the episode looks ahead at how sustainability communication is evolving: becoming more data-driven and evidence-based, while still relying on storytelling and real-world examples to bring it to life.

Do we need to rethink — or even rebrand — how we communicate sustainability?

In this episode of Sustainability Review, Matthew Campelli is joined by Franzisca Weder, Professor of International Organizational Communication and Sustainability Communication at Vienna University Business School.

Together, they explore three distinct approaches to sustainability communication: communicating of, about, and for sustainability — and why the last of these might be the key to driving real change. The conversation challenges conventional thinking, moving beyond reporting and awareness towards communication that actively mobilises people.

Franzisca also shares how organisations can uncover unexpected sustainability storytellers within their teams, and why creating the right internal conditions is essential for those voices to emerge.

Finally, the episode looks at a bigger shift: how today’s disruptions might offer organisations a chance to redefine what sustainability means — and for communicators to sharpen how they frame and contextualise it.

What happens when doing your job well puts you in direct conflict with someone else doing theirs?

In this episode of Sustainability Review, we explore “embedded conflict” – a tension built into roles, KPIs and incentives that can quietly stall progress.

Anna Krotova, Sustainability Lead at Picnic and author of How to be a Chief Sustainability Officer, shares how she navigated this firsthand, balancing emissions targets against commercial pressures. The conversation unpacks how to reframe conflict, avoid unproductive stand-offs, and make progress without forcing compromise that leaves everyone dissatisfied.

If you’re working in sustainability – or any role where priorities collide – this is a practical look at how to move forward more effectively.

Isabella Bertold is going on an adventure to show there’s a different way for athletes to communicate about sustainability and the importance of nature.

The Canadian sailor and cyclist is preparing for an expedition that will take her by boat from the UK to Norway, and then across the Norwegian fjords by bike, joined by a handful of other intrepid explorers.

She shares her belief that the most powerful sustainability stories are told through raw, visceral experiences that show athletes in direct contact with the elements.

In this episode, Isabella discusses the tension between sustainability and performance in sport, the value of strong partnerships, her time leading the Canadian Women’s America’s Cup team, her role with Canada SailGP and what sailing can learn from cycling when it comes to building partnerships and supporting women’s sport.

Most climate tech startups aren’t investing in sport sponsorship – yet.

Many see it as too expensive, misaligned with their values, or unable to deliver on goals like awareness and adoption.

But one company is breaking the mould. Svante, a carbon capture startup from British Columbia, has teamed up with Speed Skating Canada on ‘Save the Ice’, a campaign that removes carbon every time someone shares their video.

For Canada’s most decorated Olympic sport, climate change isn’t abstract, it’s existential. In this episode, we learn more from Svante and Speed Skating Canada about their partnership, and why more climate tech companies should think about getting involved in sport.

In this episode, Nicola Barr talks about her work with FrontRunners — the athlete-led climate movement co-founded by Emma and David Pocock.

She shares how the group mobilised more than 150 athletes to support the 'Duty of Care' campaign, calling for a law that would require politicians to consider climate impacts on young people.

We also talk about the origins of the movement during the Black Summer bushfires, why athlete voices still matter, and how FrontRunners is now helping under-resourced sports organisations take action behind the scenes.

A recent newsletter explored the idea that athlete investors – those backing climate tech and renewables – might ultimately hold more sway in the sustainability space than athlete advocates.

But this follow-up podcast conversation with US rower Christine Cavallo serves as a powerful reminder that influence comes in many forms. Even without financial investment, athletes who are knowledgeable and committed can play a crucial role in the climate transition.

Christine brings a unique perspective, having experienced sustainability through the lenses of elite sport, academia, public policy and now the private sector in her role at the UN Global Compact.

She argues that business holds the key to meaningful progress on climate and environmental justice – and that sport could be a powerful testing ground for scaling new technologies, if it chooses to embrace that role. The episode is a wide-ranging and thought-provoking listen.
