In this insightful and energising episode of Straight Talking Sustainability, host Emma Burlow sits down with Crista Buznea, Head of Sustainability Marketing at Ecologi, to explore how effective communication can transform sustainability from a worthy burden into an engaging, dopamine-filled journey that drives real business action.
With a background spanning tourism marketing at Heathrow and TUI before transitioning into sustainability leadership, Crista brings unique perspective on what actually works when trying to bring sustainability to the masses through authentic storytelling, strategic listening, and remarkably, the occasional use of negative messaging.
Crista's career transformation began during travels through Thailand and Cambodia, where she witnessed the dark side of tourism that her university degree had glamorised: child exploitation, fake orphanages, environmental pollution, and animal welfare issues.
This awakening led her back to university for another degree, then into roles at Heathrow and TUI where she applied marketing skills to sustainability challenges, successfully integrating sustainability into every in-flight entertainment magazine, on-screen content, in travel agencies, and through video campaigns.
Her mission has always been bringing sustainability to the masses, making it accessible rather than corporate, engaging rather than jargon-filled.
When the pandemic eliminated tourism jobs including Crista's, she showed up on LinkedIn every day telling sustainability stories, filming content, and building consistency that ultimately attracted Ecology.
They offered her a platform doing sustainability "very differently to anything I'd ever seen," using gamification and creating what Crista describes as "an environment full of dopamine" that makes sustainability genuinely engaging.
This philosophy challenges the traditional worthy, anxiety-inducing, difficult journey narrative that dominates much sustainability communication, suggesting instead that positive energy and accessible entry points drive far more participation than guilt and complexity.
The conversation centres on Ecologi's latest campaign, "Sustainability Shouldn't Be Unsustainable," which emerged from Crista's social listening at climate conferences and events.
Working with over 24,000 businesses gave her extensive exposure to sustainability leaders' challenges, and she consistently heard paradoxical demands: integrate sustainability on the ground but also be a strategic thinker, speak up but not too loud, don't be afraid of greenwashing but don't be green-hushed either.
The campaign mirrors these tensions back to the industry, acknowledging that sustainability professionals are caught between business objectives and regulatory pressure, between optimistic targets and harsh reality, between spreadsheets and storytelling.
Crista reveals fascinating insights from Ecologi's marketing experiments testing positive versus negative messaging, carrot versus stick approaches. Their weekly "Good News" series generates 20% of weekly engagement, proving positive content works.
However, when testing the same message framed as a barrier versus a motivation, barriers (the stick, the negative framing) perform marginally better.
This counterintuitive finding challenges the sustainability sector's growing emphasis on positivity-only approaches, suggesting that balanced communication acknowledging both challenges and opportunities resonates more authentically than relentless optimism or doom-focused messaging.
The episode explores critical sustainability marketing challenges including AI-generated content that lacks authenticity (easily spotted through overuse of dashes, lists of three, and algorithmic patterns), green-hushing driven by Western political changes and business caution, and the constant need to simplify jargon (carbon neutrality, net zero, beyond value chain mitigation) into accessible language that creates "light bulb moments" for business audiences.
Crista emphasises that great sustainability leaders navigate paradoxes daily, finding middle ground between competing tensions rather than choosing one extreme.
Emma and Crista discuss the toolkit for engaging any business through understanding their barriers and motivations. Barriers include financial constraints, time scarcity, lack of internal knowledge, and doubt about business returns.
Motivations include competitive advantage, brand reputation, customer attraction, and ability to hire and retain quality staff. Ecologi's annual Climate Commitment Survey consistently shows these as top drivers, with case studies like Co-op demonstrating customer and colleague engagement success, and University of Derby's net zero business school building showcasing student-driven demand for sustainability leadership.
The conversation addresses the criticism of carbon offsetting, with Crista explaining Ecology's evolution from B2C to B2B, from focusing solely on offsets to helping businesses calculate footprints, reduce emissions (Ecologi reduced their own by 20% year-on-year), and submit Science Based Targets.
She uses a powerful university analogy: you wouldn't approach a first-year student on day one demanding to see their PhD, yet sustainability communications often expect businesses to jump immediately to advanced action.
Starting with accessible steps like tree planting creates captive audiences for deeper education about the difference between carbon neutrality (passive offsetting) and net zero (requiring 90% emissions reduction).
Crista shares inspiring transformation stories from businesses like PropellerNet, Krystal Hosting, and Jump Creative who started with simple tree planting in 2020 and five years later are B Corps with solar panels, decarbonised operations, and comprehensive sustainability strategies.
This journey model proves that accessible entry points do not trap businesses in superficial action; rather, they create stepping stones towards more ambitious work. The criticism that offsetting prevents "real" action ignores the reality that many businesses need tangible, understandable starting points before they can grasp complex reduction strategies.
The episode tackles the role of AI in sustainability communications, with Crista acknowledging she uses AI multiple times daily as an efficiency tool whilst warning against losing humanity and authenticity.
AI cannot read body language, hold space for complex emotions, or tailor conversations word-by-word based on what it absorbs from the other person. The sales team at Ecology no longer uses presentation decks, instead spending the first 10-20 minutes of meetings simply listening to potential customers' problems, then tailoring responses to those specific challenges rather than delivering generic pitches.
Emma explores the importance of social listening and reading the room, noting that what works in one corporate culture may fail in another, what resonated in the 1990s may not work today, and sustainability professionals need skills to pivot instantly between firing on all cylinders with mature clients and approaching defensive, cautious clients with completely different messaging.
This adaptability, combined with genuine curiosity about motivations and barriers, separates effective sustainability engagement from frustrated professionals wondering why their excellent case studies keep falling flat.
The conversation concludes with Crista's mentoring advice that applies to both young professionals and business leaders: consistency over intensity. Rather than intense January enthusiasm that fades by February (the "gym effect"), sustainable progress requires showing up daily, taking small steps, and building momentum through regular action rather than sporadic bursts.
Crista's own career exemplifies this, as daily LinkedIn storytelling during the pandemic created the visibility that led to Ecologi discovering her. For businesses, this means avoiding the trap of "sustainability week" or "sustainability month" in favour of recognising that every day is sustainability day.

Key Sustainability Marketing and Engagement Insights:
(03:58) The dopamine difference: "It wasn't corporate at all. It was engaging. It was using gamification. It was genuinely an environment full of dopamine, where I was like, wow, this is if this is how we start promoting sustainability, I think it will really catch fire."
(06:29) Social listening in action: "I've been going to a lot of climate events and conferences... I'm always trying to activate my social listening and truly understand what sustainability leaders are feeling because then I can take that away and know how to engage them more."
(07:22) The paradox campaign: "We're being told integrate sustainability on the ground, but also be a great strategic thinker... speak up, but not too loud... don't be afraid of greenwashing, but don't be green-hushed as well."
(11:06) Simplification as marketing: "We have so much jargon... It's really, really important to simplify that. And that's one of the things that I really love as a marketer is the moments where I have those clicks and I can see the light bulb."
(14:18) The engagement toolkit: "Barriers and motivations are essentially the carrots and the sticks. And somewhere within that, you will always find the tool that you can use to engage any business. It's just about understanding and knowing the toolkit."
(17:30) AI as tool not replacement: "I use AI every single day, multiple times a day... It's a very helpful tool to structure my thoughts... But an AI can't hold space. It's only a human that has the ability to hold space and navigate and be able to know how to tailor based on almost word by word."
(19:25) Authenticity warning: "AI uses certain things that are quite obvious. Em dashes, lists of three... Just make sure that once you have the outline, you inject personality, you bring it back to some authenticity."
(22:42) The negative versus positive test: "We were talking about barriers, triggers, and motivations, the same message as a barrier versus a motivation, barriers perform better. So the negative does perform slightly better... People respond a lot better to the stick, sadly, rather than the carrot."
(33:07) The university analogy: "You wouldn't go to a first year university student on their first day and say, show me your PhD, you're not doing good enough work... You're saying, hey, you are on a journey, you're learning, come back tomorrow."
(37:14) Timing and urgency: "1.5 degrees back in 2015... that's no longer an achievable target. We're talking way above that. So actually, Cristiana Figueres recently said... we need to throw everything. We need to throw the kitchen sink at it."
