Why Climate Marketing suddenly sounds so careful

Why Climate Marketing suddenly sounds so careful

Over the past two years, climate communication has noticeably changed tone.

The optimism is quieter.

The language is more cautious.

The claims are more qualified.

And many sustainability reports now read like they’ve been reviewed by three legal teams, two risk committees and at least one executive whose primary hobby is deleting adjectives.

That shift isn’t accidental.

Climate marketing is entering a far more scrutinised era, one shaped by:

  • regulatory pressure

  • greenwashing concerns

  • political polarisation

  • investor scrutiny

  • audience scepticism

  • disclosure obligations

And increasingly, organisations are trying to balance two competing fears:

  • saying too much

  • saying too little

The result is a communications environment where sustainability messaging feels significantly more restrained than it did five years ago.

Not because climate action became less important.

But because climate claims themselves have become high-risk territory.

Greenwashing scrutiny changed the communications landscape

For years, sustainability marketing operated in a relatively low-accountability environment.

Broad environmental claims often passed with minimal scrutiny.

Companies could publish phrases like:

…without being expected to provide detailed evidence explaining what any of those claims actually meant.

That environment has changed rapidly.

Globally, regulators are increasing pressure on environmental marketing claims and sustainability disclosures.

In Australia, the Australian Securities and Investments Commission (ASIC) has intensified enforcement activity around greenwashing and misleading sustainability-related representations. 

In 2023, ASIC commenced legal action against multiple organisations over allegedly misleading environmental claims, signalling that sustainability communication is no longer being treated purely as branding language.

Meanwhile, the Australian Competition and Consumer Commission (ACCC) found that 57% of businesses reviewed in an internet sweep made concerning environmental or sustainability claims.

Globally, regulatory pressure is also increasing.

The European Union’s proposed Green Claims Directive aims to require organisations to substantiate environmental claims with credible evidence and verified methodologies.

The US Securities and Exchange Commission (SEC) has also pushed forward climate-related disclosure requirements aimed at improving consistency and transparency around climate risk reporting.

Taken together, these developments are fundamentally changing how organisations communicate about sustainability.

Because climate claims are no longer viewed primarily as marketing language.

They’re increasingly viewed as legal, financial and reputational risk territory.

Climate communication is moving from aspiration to substantiation

One of the biggest changes happening right now is that sustainability messaging is becoming less aspirational and more evidence-driven.

Five years ago, many climate campaigns focused heavily on:

  • vision

  • ambition

  • purpose

  • future impact

That style of communication reflected the broader cultural moment around ESG and corporate purpose.

Now the environment is different.

Stakeholders increasingly want:

  • measurable outcomes

  • operational detail

  • verified reporting

  • transition planning

  • emissions transparency

  • near-term progress

This shift is partly driven by audience maturity.


But it’s also driven by investor pressure.

75% of investors say companies should report the relevance of sustainability matters to their business model, while many also express concern about the reliability of sustainability reporting.

In other words:
the appetite for sustainability information is still strong.

But expectations around evidence have increased dramatically.

This is forcing organisations to rethink how they communicate climate commitments publicly.

Because broad sustainability positioning without measurable proof increasingly creates reputational vulnerability.

Companies are becoming more cautious — sometimes too cautious

In response to rising scrutiny, many organisations have significantly softened sustainability messaging.

You now see:

  • more disclaimers

  • more conditional language

  • fewer absolute claims

  • heavier emphasis on technical reporting

  • greater legal oversight of communications

  • increasingly cautious wording around targets and timelines

That caution makes sense.

The consequences of poorly substantiated sustainability claims can now include:

  • regulatory investigations

  • litigation risk

  • investor backlash

  • reputational damage

  • public accusations of greenwashing

For communications teams, the pressure is intense.

Many sustainability reports now sound like they were drafted inside a compliance bunker where every sentence was forced to survive a legal stress test before publication.

The challenge is that over-managed communication often becomes unreadable.

And when sustainability messaging becomes too defensive, audiences disengage.

Because while stakeholders want accuracy, they also still want:

  • clarity

  • accessibility

  • coherence

  • narrative structure

  • understandable language

The organisations struggling most right now are often the ones trying to eliminate all communications risk entirely.


That rarely works.

Because communication that sounds excessively cautious can sometimes create a different kind of scepticism:

if the language feels evasive, audiences start wondering what’s being avoided.

Audiences are becoming significantly more climate-literate

Another major reason climate communication has changed is because audiences themselves have changed.

Five years ago, many sustainability terms still sounded relatively technical or unfamiliar to the average reader.

Now audiences increasingly understand:

  • net zero terminology

  • offset controversies

  • Scope 3 emissions

  • greenwashing risks

  • transition planning

  • disclosure gaps

  • carbon accounting complexity

This shift has been accelerated by:

  • increased media coverage

  • investor education

  • political debate

  • regulatory scrutiny

  • social media analysis of climate claims

People are asking more sophisticated questions.

For example:

  • What specifically changed?

  • What evidence supports this?

  • Is this independently verified?

  • What role do offsets play?

  • What are the trade-offs?

  • What still isn’t solved?

That means vague sustainability language no longer lands the same way it once did.

A phrase like:

“leading the transition to a sustainable future”

…might have sounded compelling several years ago.

Today, many audiences interpret it as generic placeholder language unless it’s supported by operational detail.

This is forcing organisations to communicate with much greater precision.

Which is ultimately healthy for the sector.


Because the era of broad sustainability slogans without measurable evidence is fading quickly.

Trust now depends on operational realism

One of the most important communication shifts happening right now is the growing importance of realism.

The sustainability brands building credibility today don’t necessarily sound more optimistic.


They sound more operationally grounded.

That includes organisations willing to:

  • acknowledge complexity

  • explain limitations

  • discuss trade-offs

  • communicate uncertainty honestly

  • provide measurable evidence

  • avoid inflated claims

This matters because trust increasingly depends on believability.

Research consistently shows that audiences reward competence and transparency more than broad institutional messaging alone.

In climate communication specifically, realism is becoming a competitive advantage.

Because audiences already understand that:

  • decarbonisation is difficult

  • transition timelines evolve

  • supply chains are messy

  • emissions reductions are uneven

  • sustainability transformation is operationally complex

What audiences distrust is communication pretending those realities don’t exist.

The strongest sustainability communication now sounds more human

One noticeable shift among organisations communicating climate issues effectively is tonal.

The messaging often sounds:

  • clearer

  • more direct

  • less theatrical

  • less jargon-heavy

  • more operationally informed

Not corporate wallpaper language.

Not endless purpose slogans.

Not sustainability copywriting that sounds like it was generated by combining:

  • a Davos keynote

  • a luxury wellness retreat brochure

  • and an AI trained exclusively on ESG buzzwords.

Instead, the communication feels:

  • specific

  • informed

  • practical

  • evidence-based

That shift is important because audiences increasingly reward clarity over performance.

The sustainability sector spent years optimising for aspiration.

Now it’s being forced to optimise for credibility.

“Credible clarity” is becoming the new communications advantage

At Third Hemisphere, one pattern appearing consistently across climate and sustainability communications is that organisations gaining trust are often the ones simplifying complexity without oversimplifying reality.

That balance matters.

Because audiences still want communication that is:

  • engaging

  • understandable

  • emotionally intelligent

But they also want:

  • evidence

  • transparency

  • operational detail

  • measurable progress

The strongest sustainability communication increasingly combines both.

Not:

  • storytelling without proof
    or

  • technical reporting without narrative

But communication grounded in what could be called:

credible clarity.

That means:

  • explaining complex transition work clearly

  • avoiding exaggerated sustainability language

  • supporting claims with evidence

  • communicating limitations honestly

  • sounding human rather than over-engineered

Some of the most effective climate communication today is surprisingly restrained.

Not because the ambition is smaller.

But because credibility now matters more than performance.

Political polarisation also changed the language around ESG

Another factor shaping sustainability communication is political polarisation.

Particularly in the United States, ESG terminology became increasingly politicised over recent years.

As a result, many organisations have started reframing sustainability language around concepts like:

  • resilience

  • energy security

  • operational efficiency

  • risk management

  • long-term value creation

In many cases, the underlying sustainability work remains similar.

The vocabulary changes.

This shift reflects a broader reality:
language itself now carries reputational and political implications.

For communicators, that creates a complicated balancing act.

Because organisations must now navigate:

  • regulatory expectations

  • investor pressure

  • public scrutiny

  • political sensitivity

  • stakeholder trust

All simultaneously.

That inevitably produces more careful communication.

The future of climate marketing will probably be less glossy — and more effective

Climate marketing hasn’t become weaker.

It’s becoming more accountable.

And while that transition may make sustainability communication feel less cinematic and less polished, it will likely make the sector more credible over time.

Because increasingly, audiences reward communication that feels:

  • realistic

  • measurable

  • operationally informed

  • transparent

  • specific


Not just emotionally compelling.

The organisations building long-term trust now are often the ones resisting the temptation to overstate progress.

Instead, they explain:

  • what’s changing

  • what remains difficult

  • where uncertainty exists

  • what can actually be verified

That approach may generate fewer dramatic slogans.

But it generates something far more valuable:
Credibility.

Final thought

Climate communication is entering a more mature phase.

The sustainability sector is moving away from an era dominated by broad ambition statements and toward one defined by substantiation, transparency and operational detail.

That transition creates challenges for marketers.

But it also creates an opportunity.

Because in a more sceptical communications environment, the organisations standing out won’t necessarily be the loudest or most inspirational.

They’ll be the ones capable of communicating complex climate work clearly, credibly and without hiding behind vague corporate language.

And increasingly, that kind of clarity is becoming far more persuasive than polish.
