What does net zero actually mean for a business?

Net zero has become shorthand for corporate climate ambition — and in the process, its precise meaning often gets lost. For a business, net zero is a specific commitment: reduce your greenhouse gas emissions as far as practically possible, and counterbalance only the small remainder with durable carbon removals.

Reduction first, removal last

The order matters. Net zero is not achieved by buying offsets against an unchanged footprint; it is achieved by deep cuts across Scope 1, 2 and 3, with removals reserved for the emissions that genuinely cannot yet be eliminated. Credible frameworks put the reduction share at ninety per cent or more of the baseline.

Why the boundary matters

A net zero commitment that quietly excludes Scope 3 excludes, for most companies, the majority of their emissions. Being explicit about what your target covers — which scopes, which parts of the business, by when — is what separates a commitment that stands up to scrutiny from one that invites it.

What it demands operationally

A serious target needs three things underneath it: a measured baseline you trust, a reduction pathway showing how each year bends the curve, and tracking that proves movement against that pathway with consistent methods. Without those, a target date is just a date.

The honest starting point

If your organisation is early in the journey, the credible first step is not announcing a distant target — it is building the measurement foundation that any target will eventually rest on. Know your number, know its evidence, and the strategy conversation becomes real.
