Overview

Carbon neutral and net zero are both used to describe a state where an organisation’s greenhouse gas emissions are “balanced” in some sense. The gap between them is not semantic, it is the difference between a genuine emissions reduction strategy and an accounting exercise.

Carbon neutral means that a company offsets its emissions by purchasing Carbon Offsets, credits representing emissions reductions made somewhere else, like a forest preservation project or a methane capture scheme. The company does not necessarily reduce its own emissions at all. It keeps emitting and buys enough credits to declare the emissions balanced. Done well, this can be legitimate. Done poorly or misleadingly, it is a form of Greenwashing.

Net zero means something fundamentally different. A net zero commitment requires the company to first reduce its direct and value-chain emissions as deeply as possible, to near zero across all scopes. Offsets are only used for a small residual of “hard-to-abate” emissions that genuinely cannot be eliminated with current technology. The order matters: reduce first, offset last, and only offset what you truly cannot cut.

Why the Distinction Matters

The Science Based Targets Initiative (SBTi), which sets the most widely recognised corporate net zero standards, draws this line explicitly. A company claiming net zero under SBTi criteria must show deep decarbonisation, typically 90–95% emissions reductions, before any residual offset use qualifies as “net zero.” Carbon neutrality achieved through offsets alone does not qualify.

The Paris Agreement and IPCC modelling both use “net zero” in the SBTi sense, a genuine near-elimination of emissions, not an offset-heavy approximation. When governments commit to net zero by 2050, they mean reducing national emissions to the bone, with any remaining gap covered by carbon removal. The same standard should apply to corporate claims, but enforcement is uneven.

This gap is precisely where Climate Litigation is expanding. Regulators in the UK, EU, and elsewhere have begun challenging companies that use “net zero” or “carbon neutral” in advertising without the underlying reductions to back them up. The UK Advertising Standards Authority has already ruled against major companies on this basis.

The Role of Offsets

Carbon Offsets are not inherently problematic, they play a legitimate role in a net zero strategy as the final tool for unavoidable residual emissions. The problem arises when they become the primary tool, substituting for real reductions. A company that buys offsets to avoid transforming its operations is not transitioning, it is delaying.

Greenwashing is most acute in this area because the terms “net zero” and “carbon neutral” look identical to a non-specialist audience. Communications professionals need to be able to explain the distinction clearly, understand what their organisation’s commitments actually entail, and scrutinise whether the language being used matches the underlying strategy.

You Might Not Expect
A company can be 'carbon neutral' without reducing a single tonne of emissions
Carbon neutrality only requires that emissions are offset, not that they are reduced. A company can increase its emissions year on year and still claim carbon neutrality by purchasing enough offset credits. Net zero, by contrast, demands deep decarbonisation first and permits offsets only for a small hard-to-abate residual. The distinction is the difference between transformation and accounting.
