Emma Burlow talks with Jessica Riches, independent filmmaker and existential crisis communication strategist, about using sex, entertainment, humour, and trusted creators to make climate communication cut through.
In this episode
Why climate communicators need to “jump off the cliff of the norm” rather than take small steps, as Jessica Riches explains at 02:57.
The three reasons people shut down when confronted with existential risks: unfamiliar unknowns, exponential risk, and the feeling that they have no agency 06:42.
How parasocial relationships and trusted voices can communicate complex ideas more effectively than distant institutions or experts 09:29.
Why Jessica Riches turned to OnlyFans as a space for reaching audiences who are often overlooked by climate campaigns 14:51.
The thinking behind Headline Newds, a campaign delivering climate news through adult-content creators 24:24.
How the project worked with creators as co-creators rather than handing them a rigid communications brief 23:38.
Why facts alone haven’t shifted public understanding of climate change, and why the messenger matters as much as the message 29:56.
The campaign’s reach, including hundreds of thousands of views and strong levels of shares and saves despite widespread shadow banning 32:28.
Why climate communicators should stop treating people as corporate audiences and start recognising them as humans with existing interests, relationships, and communities 44:55.
Jessica Riches’ advice to take bigger creative risks, challenge conventional impact metrics, and consider a “little mini revolution” 45:48.

Memorable moments
“Better facts are not going to make this better.” Jessica Riches argues that climate communication has focused too heavily on accuracy, while overlooking story, trust, and cultural relevance at 30:00.
Jessica Riches describes Headline Newds as a way to combine climate facts with “a few puns and some sexual innuendo” while reaching communities that climate campaigns rarely prioritise 43:15.
The central challenge for sustainability professionals: being boring is rarely safer than being unexpected, especially when the goal is to reach people beyond the usual sustainability audience 45:07.
Content warning
This episode includes sexual content, strong language, discussions of pornography and sex work, and references to climate-related death and societal collapse.

The conversation focused on the implications of the UNEP report Limiting Overshoot, which warns that global warming could reach 1.8°C even under the best-case pathway, with current policies potentially leading to 2.6°C.
The discussion explored whether sustainability professionals should replace the 1.5°C message with 1.8°C, or stay focused on the existing target. The answer depends on the audience. People who already understand the science may be ready to discuss overshoot in more depth. For others, introducing another number could create confusion, weaken existing targets, or encourage a “what’s the point?” response.
Key takeaways
The UNEP report says overshoot is unavoidable, but warming can still be brought back down through a “peak and decline” strategy.
Current policies could lead to 2.6°C of warming 04:18.
Every fraction of a degree above 1.5°C increases the risks 04:40.
The required actions include immediate emissions cuts, methane reductions, a rapid transition to net zero, carbon dioxide removal, and adaptation 05:15.
Don’t add complexity before people understand the basics of climate change, urgency, and agency 07:21.
If an organisation already has a 1.5°C target, introducing 1.8°C without context could muddy the waters 10:00.
Sustainability messaging should reflect the audience’s level of awareness and readiness 10:52.
If the basics aren’t in place, focus on carbon literacy training, lunch and learns, e-learning supported by real engagement, or showing the National Emergency Briefing 14:08.
If the basics are in place, identify what’s preventing faster emissions reductions, stronger advocacy, supply-chain transformation, or industry leadership 15:46.
Overwhelm can be reduced by finding the “nugget of truth,” breaking the issue down, and acting on what’s achievable 12:19.
Supporting sustainability teams matters, even when sustainability isn’t part of the job title 13:43.

Ask honestly:
Do the climate basics exist across the organisation?
Is the current target driving real progress?
What’s stopping faster and bigger carbon reductions?
Is there a rock in the way that needs to be identified and removed?

The episode’s central message is clear: 1.8°C is a warning, not a reason to stop. There’s still a great deal to do 18:47.
Yes, we’re heading towards 1.8 degrees of warming, but there’s still a damn lot we can do in the meantime. Don’t stay in overwhelm. Get the basics in place, support each other, and take action.

This episode explores how businesses can bridge the gap between setting net zero targets and actually achieving them, moving from data collection to actionable strategies. Emma Burlow is joined by Louise Rehbinder, who delves into the Exponential Roadmap Initiative’s Five Pillars framework and its essential role in forming resilient, actionable net zero strategies for businesses of all sizes.
The Target-Action Gap:
Many companies have ambitious net zero goals, but employees are often unclear on how to achieve them. This episode discusses concrete ways to close that gap (Emma Burlow 00:01:19).

Intro to Exponential Roadmap Initiative:
Louise Rehbinder explains the organization’s mission, straddling think-tank and consultancy, and how they support corporates with up-to-date climate action guidance (Louise Rehbinder 00:02:16).

The Five Pillars Explained:
The Exponential Business Playbook is structured around five key pillars:
Reducing a company’s own emissions (Scope 1 and 2)
Value chain emissions (Scope 3: upstream, downstream, suppliers, customers, products)
Providing solutions that replace high-emission practices
Enabling mechanisms: finances and investment
Policy and social narrative for systemic change

(Louise Rehbinder 00:07:59 – 00:10:22)
Applicability to Small Businesses:
The playbook isn’t just for big corporates; it is designed to be accessible, with free tools like SME Climate Hub for smaller organizations (Louise Rehbinder 00:04:42).

Moving Beyond Data Collection:
The importance of balancing effort between getting accurate carbon accounting and actually implementing actions. Companies can make significant progress with available data without waiting for perfection (Louise Rehbinder 00:19:18).

Strategic vs. Operational Approaches:
How the playbook helps elevate climate action from operational and compliance-driven steps to integral parts of business strategy (Louise Rehbinder 00:33:18; Emma Burlow 00:33:25).

Practical Examples & Industry Leadership:
Some members use the playbook as the basis for company-wide strategy, particularly advanced IT, finance, or sustainability-led firms. Case studies include companies enabling broader systemic change, such as Stegra (Green Steel) and Unilever’s policy engagement (Louise Rehbinder 00:34:43–00:37:05).

Memorable Quotes
“Knowing your numbers does not reduce your emissions. …You need to also actually do the activities.” – Louise Rehbinder 00:17:52
“Climate is just one aspect that comes into play—something that will happen eventually. And it is about competitiveness for the companies.” – Louise Rehbinder 00:32:38

Resources Mentioned
Exponential Business Playbook
SME Climate Hub

Takeaways
The Five Pillars approach helps businesses systematically move from targets to tangible climate action.
Action and influence (Pillars 3, 4, and 5) are as crucial as accurate reporting (Pillars 1 and 2).
Tools and frameworks are freely available and can serve as “handholders” for sustainability teams at any stage.
