Why PwC’s 2025 sustainability forecast is basically a memo to every marketing department.
PwC just dropped their 2025 sustainability forecast, and spoiler: it’s no longer a “green agenda” it’s a business survival strategy. These sustainability trends for 2025 aren’t just shaping boardrooms; they’re reshaping marketing sustainability, customer expectations, and the way brands communicate.
From hiring to procurement to the way brands tell their stories, sustainability is now the backbone of business strategy. And yes – it’s transforming marketing communications, customer experience and how brands prove their ethics in an increasingly conscious market.
The companies winning in 2025 won’t be the ones shouting eco-slogans. They’ll be the ones demonstrating authentic ESG marketing, transparent processes and low-impact customer experiences.
If sustainability is becoming the operating system of modern business, then it must also become the operating system of brand storytelling.
Let’s dive into the five sustainability trends shaping 2025 and what they mean for marketing departments.
1. ESG Isn’t a Badge – It’s Brand DNA
In 2025, ESG marketing isn’t a box-ticking exercise; it’s the foundation of brand credibility. Customers and stakeholders now expect brands to integrate sustainability deep into their operations – not sprinkle eco statements across their website.
Impact on marketing departments:
- Authentic sustainable marketing strategies now outperform fluffy claims.
- Consumers expect transparency, proof, and behavioural alignment.
- ESG performance is influencing customer loyalty and brand trust.
This is why thoughtful tactics like handwritten direct mail on recycled paper from a company that focuses on carbon neutral delivery remain powerful – they feel intentional, low-waste, and aligned with a sustainable customer experience.
2. Tighter Regulations Mean Words Matter More Than Ever
With stronger sustainability regulations in 2025, generic terms like “eco-friendly” or “green” aren’t enough. Brands now carry legal responsibility for every sustainability claim they make.
What this means for marketers:
- Your sustainability messaging must be specific, evidence-based, and verifiable.
- Compliance and marketing must work hand-in-hand.
- Vague language risks fines, backlash, and customer mistrust.
Clear, accurate ESG communications will become a crucial competitive advantage.
3. Transparency Isn’t Optional – It’s a Selling Point
One of the biggest sustainability trends 2025 is radical transparency. Customers want to know exactly where products come from, how materials are sourced, how suppliers are chosen, and what your carbon footprint really looks like.
For marketing teams:
- Transparency is now part of your content strategy.
- “Behind the scenes” is no longer a bonus – it’s an expectation.
- Honesty and humanity build stronger connections than perfection.
Human-centred communication methods, like handwritten direct mail, naturally signal transparency, care and authenticity.
4. Sustainability is Redesigning the Customer Experience
Sustainability today goes beyond the product. Customers want to see it reflected across the entire journey — packaging, onboarding, nurture flows, retention, even aftercare.
Marketing implications:
- High-volume digital spam is being replaced by low-impact, intentional communication.
- Customers expect brands to minimise waste across all touchpoints.
- Personalisation and ethical relevance matter more than mass reach.
This is why brands are leaning into sustainable alternatives like recycled print marketing, carbon-neutral direct mail, and human-first campaigns that feel meaningful – not disposable.
5. People-First Sustainability is Taking Centre Stage
The sustainability conversation is expanding from “planet impact” to “people impact.” PwC highlights the rise of ethical workforce practices, wellbeing, DEI, and community-centred values.
Why this matters for marketing:
- Tone of voice must reflect empathy and human understanding.
- Human-centric marketing is becoming a high-performing strategy.
- Customers reward brands that communicate with emotional intelligence.
And what communicates humanity better than a personalised handwritten note? No algorithm. No churn. Just real connection.
2025 Requires Marketing That Is More Transparent, More Human, More Sustainable
The future of marketing isn’t faster or louder – it’s more intentional. These sustainability trends prove customers want communication that aligns with their values, reduces impact, and reflects a brand’s true behaviour.
Marketing departments must adapt by building sustainable strategies, reducing waste, and rethinking customer touch points.
Slow, thoughtful, ethical communication will define the next era of brand loyalty.
