Why Words Matter in the Sustainability Conversation

If you’ve been following this series, we’ve talked about carbon footprints and scope emissions, how we measure our impact and where those emissions come from. But recently, while revisiting material from a class by Good-Loop's Good Media Academy, something hit me: even when people want to do the right thing, we often get tangled in the words.

Net zero. Carbon neutral. Offset. Insetting.

They sound impressive, but do we really understand what they mean?

Why language matters

In sustainability, words carry weight.

According to a 2022 study by the UK Advertising Standards Authority (ASA), most consumers confuse “net zero” and “carbon neutral,” thinking they mean the same thing. And as WARC found in their global review of sustainable campaigns, only 9.7 % were actually viewed as credible by consumers.

That’s huge, and not in a good way.

When people don’t understand your sustainability message, they don’t trust it. And when they don’t trust it, they tune out. A 2023 KPMG study revealed that 54% of consumers would stop purchasing from a brand they found to be misleading about sustainability.

So yes, getting the terminology right isn’t about buzzwords; it’s about trust.

Why this matters in Tanzania

Even though these studies were done elsewhere, the same principle applies here. Sustainability is still new territory for many local organisations. If we misuse terms or over-claim our efforts, we risk turning an important movement into another marketing cliché.

We’ve already seen a rise in “eco” and “green” labels locally, from packaging to product claims, but few explain what exactly makes them sustainable. The result? Confusion and skepticism.

So, let’s slow down and get clear on the basics.

Busting the carbon jargon

Carbon neutral

This means a company has measured its emissions and then purchased carbon credits to offset the same amount. It doesn’t mean the company has reduced its emissions; it just means that it has balanced them by funding equivalent reductions elsewhere.

Think of it as paying for balance. It’s a good first step, but not the finish line.

Net zero

This goes further. To claim net zero, a company must:

• Cut at least 90 % of its emissions (Scopes 1–3).

• Set short- and long-term targets (2030 & 2050) aligned with the 1.5 °C global pathway.

• Have those targets externally verified.

Net zero is about transformation, not transactions. It’s the difference between dieting and changing your lifestyle.

Offsets vs. Insetting

Offsets happen outside your operations. You buy carbon credits from another project, say, a forest in another country, to compensate for your own emissions.

Insetting, on the other hand, happens within your supply chain. It’s when a company invests directly in making its own processes cleaner, switching to renewables, supporting regenerative farming, or improving supplier practices.

Both have value, but insetting builds resilience from within.

The mitigation hierarchy

Here’s a simple way to remember the right order of action:

Avoid → Minimise → Restore → Offset

That means first stopping emissions where you can, then reducing what’s left, restoring what’s been damaged, and only offsetting as a last resort.

Tree planting, for instance, is great, but it can’t fix everything. To reach global net zero by 2050, we’d need an extra 1.6 billion hectares of forests, five times the size of India!

So yes, plant trees, but pair that with smarter energy, better transport, and sustainable production.

Bringing it home

For Tanzanian businesses, this clarity matters more than ever. As local companies begin publishing verified sustainability reports, the rest of us, marketers, communicators, and entrepreneurs, need to speak the same language.

If we say net zero when we really mean carbon neutral, we dilute credibility for everyone. If we make claims we can’t prove, we lose the very trust sustainability depends on.

The truth is, sustainability storytelling is only powerful when it’s clear, honest, and measurable.

Let’s keep learning together.

Words shape understanding. Understanding shapes action. So next time you see a company call itself “carbon neutral”, ask: How? If it claims “net zero”, ask: What’s their plan to get there?

The future of sustainability in Tanzania depends not only on doing the work, but also on getting it right.
