Why Sustainability Communications Often Lose Clarity (and How to Fix it)

Sustainability is inherently complex. That’s not new, and it’s not going to change. You’re dealing with multiple topics, evolving standards, technical detail, and a constant stream of new expectations. It’s a lot to hold together. The problem is that this complexity often carries straight through into how companies communicate.

You see it in long explanations, dense language, and messages that try to do too much at once. The intention is usually sound — to be accurate, complete, and transparent. But somewhere in that process, clarity starts to slip.

Not because the thinking is weak, but because too much is being carried in a single message. When that happens, the burden shifts to the audience. They have to work harder to understand what’s actually being said: what matters, what’s changed, and why they should pay attention. And most audiences simply won’t do that work.

That’s where the disconnect begins.

There’s also a persistent assumption that more detail automatically builds credibility. Sometimes it does, but only when it’s structured in a way that people can navigate. Without that, detail quickly becomes noise. Clarity isn’t about removing complexity, it’s about organising it.

That means being deliberate about what comes first, what supports it, and what doesn’t need to sit in the main message at all. It requires a different kind of discipline; not just gathering information, but shaping it. Deciding what carries weight, and accepting that not everything can.

This is often the uncomfortable part. Simplifying a message can feel like leaving something out, or risking misinterpretation. But the alternative isn’t neutral. When everything is included, not everything is understood. That's a problem.

A more effective approach is to work in layers. Start with the core message — the part that needs to land quickly and clearly. Then build around it with supporting detail that’s available when needed, but doesn’t overwhelm the initial point. Done well, this doesn’t reduce accuracy. It makes it usable.

It also makes consistency easier. When the core message is clear, it’s far more likely to be repeated in the same way across teams and channels. Without that, messages start to drift, and over time, they fragment.

The organisations that handle this well don’t necessarily say less. They structure things differently. They prioritise clarity at the top and complexity underneath, making it easier for different audiences to engage at the level they need.

And that matters, because in sustainability communications, the goal isn’t to say everything. It’s to be understood — and to stand up to scrutiny.
