This gap is fixable. This article walks through auditing your current communications, prioritizing material topics, building evidence-backed messages, choosing the right channels, assigning clear ownership, managing greenwashing risk, and measuring what matters.
Key Takeaways
- Connect ESG messaging to business priorities and measurable performance, not a standalone marketing campaign
- Prioritize material topics instead of communicating every initiative with equal weight
- Support every claim with clear scope, methodology, and data limitations
- Treat ESG communication as continuous and two-way, not an annual report exercise
What Is ESG Communication—and Why Does It Matter?
ESG communication is how a company explains its environmental, social, and governance actions, risks, and progress to stakeholders. It's distinct from a few related concepts:
- ESG reporting is the evidence layer: metrics, methodologies, boundaries
- ESG communication translates that evidence into stakeholder-facing narratives across filings, websites, and dialogue
- CSR is the underlying program or commitment layer
- Sustainability marketing is promotional, consumer-facing messaging—separate from investor-grade disclosure
Those narratives rest on three pillars:
- Environmental: emissions, energy, waste, and resource use
- Social: workforce practices, safety, human rights, and community impact
- Governance: ethics, board oversight, risk management, and transparency
Why does this matter for US companies? In PwC's 2024 global investor survey, 71% of investors said companies should embed sustainability into strategy, and 75% said quantified impacts help clarify material risks.
Credibility is the gap: 44% of investors said sustainability reporting contains unsupported claims, while 76% said third-party assurance increases trust (PwC's 2024 Global Investor Survey).
Companies that tie ESG claims to real evidence—and show their work—earn trust that generic sustainability messaging does not.
Build the Foundation for the Strategy
Audit Your Current ESG Position
Before writing a single message, inventory what already exists:
- Existing commitments, policies, and data sources
- Reports, website pages, and investor materials
- Press releases, social content, and leadership statements
Look for gaps between what you do, measure, disclose, and claim. Missing baselines and inconsistent terminology across teams are common, and they undermine credibility later.
Run a Materiality Assessment
Materiality assessments combine stakeholder concerns with the ESG issues most relevant to your business model and risk profile. Different sectors prioritize differently:
| Sector | Priority Topics |
|---|---|
| Technology | Security, privacy, energy use, responsible AI |
| Healthcare | Patient safety, data privacy, clinical ethics |
| Consumer | Product safety, sourcing, packaging lifecycle |
| Energy | Emissions, worker safety, transition strategy |
| Financial services | Governance, security, financed exposure |
GRI's materiality process is a useful model: understand context, identify impacts, assess significance, then prioritize for reporting. Turn the output into a short, manageable list: five or six topics, not twenty.
Map Audiences and Their Needs
Every audience needs something different:
- Investors and analysts want risk management detail, targets, and performance trends
- Employees want accessible explanations and practical relevance
- Customers and suppliers want evidence tied to specific products or practices
- Regulators want disclosure accuracy and consistency with filings
Match each audience to their preferred channel and level of technical depth.
Set Objectives, Ownership, and Approvals
Tie communication objectives directly to business goals, such as supporting investor engagement or clarifying risk management.
Assign clear owners across sustainability, finance, legal, investor relations, and PR:
- Who owns source data and calculation methods
- Who approves messaging and claims
- Who controls publication timing
Leadership and board involvement matters here, especially for public companies making forward-looking claims. This isn't a task to delegate entirely to a marketing team.
Select Frameworks and Data Controls
The US disclosure landscape shifted in 2024 and 2025. The SEC adopted climate disclosure rules in March 2024, stayed them in April, then voted in March 2025 to end its defense of the rules (SEC's fact sheet on the rescission).
Meanwhile, California's SB 253 and SB 261 create separate reporting obligations for companies doing business in the state above certain revenue thresholds.
This is not legal advice. Work with counsel to confirm applicability. What you can control internally:
- Consistent definitions and reporting boundaries
- Documented calculation methods and version control
- Clear distinction between internally reviewed data and externally assured data
Don't imply a level of verification you don't actually have.
Create a Credible, Defensible ESG Narrative
Connect ESG to the Business
Generic claims like "committed to sustainability" don't hold up. Every claim needs a specific action, business context, and supporting evidence behind it. Connect material ESG priorities directly to your operating model, capital allocation, and long-term strategy.
Build a Message House for Each Topic
Create a repeatable structure for every priority topic:
- Commitment — the specific pledge tied to a material priority
- Action — programs and decisions already underway
- Metric and baseline — the measure used and the starting point
- Target and timeframe — the destination and the deadline
- Current status — progress against the baseline today
- Limitations — scope gaps the data does not cover
One core message, built this way, can flex into an investor update, an employee explanation, a website page, or a social post: same facts, different depth.
Use Evidence Stakeholders Can Evaluate
Document the source, reporting period, boundary, and methodology behind every material claim. Third-party assurance, audits, or certifications can strengthen credibility, but be precise about what the external review covers. A limited assurance opinion is not the same as a full audit.
Communicate Progress and Setbacks Honestly
A credible narrative reports missed targets and changing methodologies, not just wins. Distinguish clearly between:
- Completed actions
- Ongoing initiatives
- Future goals
- Unfunded aspirations
Build a review step specifically to strip out absolute or vague language before anything is published.
Tailor Messaging by Audience
Investors need risk, governance, and performance trend detail. Employees and customers need accessible, practical framing.
Whatever you publish, keep it consistent with filed disclosures. Nothing on an ESG page should contradict an earnings call.
A message library and approved Q&A document help spokespeople stay consistent across settings.
Execute an Always-On, Multichannel Communications Plan
Build a Channel Architecture
Map each audience and message to the right combination of channels:
- IR website and sustainability pages
- Press releases and investor meetings
- Employee platforms and social media
Choose channels based on audience needs and your ability to maintain them, not because a channel is trending.
Set a Realistic Cadence
Build an editorial calendar around reporting cycles, earnings, and operational milestones. Balance major annual disclosures with smaller, evidence-backed updates throughout the year, so ESG communication doesn't only appear once a year or only when there's good news. Gateway's own guidance on creative communication between regulated earnings cycles reflects this same principle: consistency between formal reporting windows builds more trust than silence.
Create a Production Workflow
- Maintain one source of truth for approved facts, metrics, and supporting documents
- Define review checkpoints (legal, finance, IR, leadership) before anything publishes
- Include a process for refreshing outdated figures and FAQs regularly
Prepare Leadership and Employees
Develop executive talking points and media training so spokespeople answer difficult questions consistently. Employees can share authentic stories, but they need clear guidance on what's approved to say publicly versus what stays internal.
Consider Integrated Communications Support
Smaller teams often lack the bandwidth to coordinate investor relations, PR, digital, and crisis communications at once. An integrated financial communications partner can fill that gap. Gateway Group, for example, works with small- and mid-cap public issuers and growth companies to coordinate investor, media, and corporate messaging under senior-led teams when internal capacity is stretched across a busy reporting calendar.
Manage Greenwashing Risk and Measure Progress
Build a Greenwashing Prevention Checklist
Before publishing any ESG claim, check it against:
- Specific evidence and reporting boundaries
- Accurate comparisons (versus what baseline?)
- No absolute language ("zero," "leader," "green") without qualification
- Clear status: ambition, funded plan, or achieved result
The FTC's Green Guides reinforce this: general environmental claims need to be specific, and qualifications must be clear and prominent (FTC's Green Guides summary).
California's Attorney General has already tested this standard against major energy companies over greenwashing allegations. Claims without evidence carry real legal exposure.
Avoid Greenhushing Too
Some companies have overcorrected into silence. Reuters reported a 20% year-on-year drop in ESG-related statements among large financial-sector companies, driven by political and regulatory caution. Silence is not the answer. Use specific, topic-level language instead of the broad "ESG" label, and disclose uncertainty honestly rather than omitting it.
Measure What Actually Matters
Separate communication outputs from outcomes:
- Outputs: content reach, publication frequency
- Outtakes: stakeholder comprehension, inbound questions
- Outcomes: investor feedback, employee understanding, message consistency
Revisit these metrics each quarter. Drop vanity reach numbers that do not move investor feedback, employee understanding, or message consistency.
Conclusion: Turn ESG Activity Into Trusted Stakeholder Communication
The same sequence holds up across industries:
- Establish a baseline and prioritize material topics
- Map audiences and build evidence-backed messages
- Assign owners, activate the right channels, and invite feedback
- Refine the program as data and stakeholder expectations change
A practical first step: convene a small cross-functional team (sustainability, finance, legal, and IR) to audit current claims and pick your top three ESG communication priorities for the next planning cycle. That keeps the workload manageable and turns real ESG activity into messaging stakeholders can trust.
If you need senior help shaping those priorities into investor- and stakeholder-ready narratives, Gateway Group advises public and growth companies on integrated financial and corporate communications.
Frequently Asked Questions
What is ESG communication?
ESG communication is how a company explains its environmental, social, and governance actions and progress to stakeholders. It differs from ESG reporting, which is the underlying data and methodology layer.
Is ESG still relevant in 2026?
Yes, though the label matters less than the underlying issues. Callan's 2024 survey found 38% of US institutional investors incorporating ESG into decisions, with wide variation by institution size, so relevance depends on your specific audience.
What does ESG stand for?
ESG stands for Environmental, Social, and Governance. Environmental covers emissions and resource use; social covers workforce and community impact; governance covers ethics and oversight.
What should an ESG communications strategy include?
It should include materiality assessment, audience mapping, evidence-backed messaging, defined channels, clear ownership, review processes, and ongoing measurement. Treat it as a continuous process rather than a one-time campaign.
How can companies avoid greenwashing in ESG communications?
Use specific, substantiated claims with transparent methodology and accurate timeframes. Report both progress and setbacks, and clearly disclose data limitations rather than glossing over them.
How do you measure the success of ESG communications?
Track communication metrics separately from ESG performance metrics, such as stakeholder understanding, engagement quality, message consistency, and progress against defined communication objectives.
