Internal and External Communication for ISO 14001
ISO 14001 Clause 7.4
Internal and external communication relevant to the management system.
ISO 14001 Clause 7.4 - Communication
ISO 14001:2026 Clause 7.4 requires the organisation to establish processes for the internal and external communication relevant to the environmental management system. The organisation determines what to communicate, when to communicate, with whom and how.
Communication is two-way. The clause covers both communications going out from the organisation and communications coming in, including responses required to relevant external communications such as complaints from neighbours or queries from customers. The processes have to make sure that information sent out is consistent with information generated within the EMS and reliable.
Internal Communication
Internal communication keeps the workforce engaged with the EMS and supports continual improvement. Sub-clause 7.4.2 requires the organisation to internally communicate information relevant to the EMS, including changes, and to provide a way for people doing work under its control to contribute to continual improvement.
Practical channels include team meetings, toolbox talks, intranet announcements, posters, briefing emails, and feedback mechanisms such as suggestion schemes or environmental incident reporting. The exact mix depends on the size and culture of the organisation.
External Communication
External communication is established by the organisation's communication processes and as required by compliance obligations. Some external communication is mandatory:
- regulatory reporting required by environmental permits or legislation;
- responding to enforcement queries from regulators;
- statutory disclosures under environmental reporting requirements;
- required communications to local authorities or fire and rescue services where applicable.
Other external communication is voluntary but can serve the organisation's purposes - sustainability reports, customer-facing environmental information, supply chain communications about environmental requirements, complaint handling, and engagement with local communities.
The standard requires the organisation to respond to relevant communications about the EMS. Complaints from neighbours about smells, noise, dust, or wastewater discharges all count, as do queries from customers about environmental performance. A clear response process is needed, with someone responsible for handling these and routing them to the right place.
What Good Communication Looks Like
The standard expects communication to be transparent, timely, factual, accurate, understandable, and not misleading. It expects information to be appropriate in format, language and media for the audience.
For external audiences in particular, environmental claims need to stand up to scrutiny. Greenwashing - making environmental claims that are not backed by evidence or that overstate the position - is a real reputational risk and a growing area of regulatory and consumer attention. Communications should be derived from EMS data, not from marketing aspirations.
Communication is one of those clauses where the structure matters more than the content. Decide what you communicate about your environmental performance, who you communicate it to, and how. Decide how complaints and queries are handled. Then run the system.
The mistake I see most often is having no clear process for incoming communication. A neighbour calls about a smell, the call gets passed to three different people, nobody owns it, and the response if it ever happens is days late. That is the opposite of what the clause expects.
I look for two things at audit. First, can the organisation show me how relevant communications get logged and responded to. Second, are external claims about environmental performance consistent with what the EMS data shows. If the website says we cut emissions by 30 percent, I want to see the data that supports that claim.
Communication is just keeping people informed - the people inside about what is going on with the management system, and the people outside who need to know. Decide what to send out, decide how to handle what comes in, and run the system properly. Most organisations already do this for safety and quality. Environmental fits the same pattern.
Practical Compliance Guidance
Communication is supported by the IMS1 Manual which sets out the communication process in Section 7.4, and by the registers used to log incoming and outgoing communications relevant to the EMS.
