Net Zero

“Net zero is a balance reached after deep reduction, not a licence to continue gross emissions unchanged. ”

Net zero sounds like the absence of emissions. It is not. It describes a balance between remaining anthropogenic emissions and anthropogenic removals over a stated period. That balance can be scientifically meaningful at the global level and operationally useful for organisations, but only when the boundary, gases, timeframe and role of removals are clear.

The IPCC distinguishes net zero carbon dioxide from net zero greenhouse-gas emissions. Carbon dioxide and other gases behave differently, and the warming outcome depends on which balance is achieved. At organisational level, a claim may cover operational emissions only, all value-chain emissions or a selected product. The same phrase can therefore describe very different scopes.

Integrity begins with gross reductions.

The UN High-Level Expert Group on net-zero commitments emphasised that non-state actors should align near-term action with science, reduce emissions across the value chain and avoid using low-quality credits as a substitute for transformation. A distant 2050 balance is weak if emissions rise through the 2020s while the organisation assumes future removals will compensate.

Residual emissions are another point of discipline. They are not whatever remains after the actions an organisation finds convenient. They are emissions that are difficult to eliminate after feasible reductions have been pursued. The definition should tighten over time as technology, policy and business models change.

Calling ordinary emissions residual too early turns a technical exception into a strategic escape route. Boundaries can make or break the claim.

For many food and commodity companies, most emissions occur in agriculture, land use and purchased goods rather than offices or factories. A net-zero claim covering only direct fuel and electricity may be numerically correct within that boundary and materially misleading about the enterprise. Scope should follow the sources that matter. Removals must also match the claim.

Avoided emissions credits do not remove an organisation's residual emissions from the atmosphere. Temporary biological storage does not provide the same durability as the carbon dioxide it is used to counterbalance. Double counting can occur when a project, buyer and host country all claim the same mitigation outcome. The word balance does not eliminate these accounting questions. Interim targets provide the test.

Credible pathways specify absolute reductions, material value-chain action, capital allocation and governance before the end date. They report gross emissions and removals separately. They also explain how acquisitions, growth or product changes affect the pathway. An intensity target can improve while total emissions increase, leaving the net-zero destination farther away. Credits create a further integrity test.

A tonne used against a net-zero claim must not be counted simultaneously by the project host, an intermediary and the buyer in ways that imply multiple climate benefits from one outcome. Corresponding adjustments address one form of double claiming in international accounting, but they do not resolve weak baselines, impermanence or social harm. Accounting integrity is necessary and not sufficient.

Scope 3 emissions make organisational net zero especially difficult.

A buyer may influence farming, processing and logistics without controlling them, while suppliers serve several customers and national inventories count the same physical emissions territorially. Overlapping inventories are normal; overlapping claims of exclusive reduction are not. Companies should describe their influence and evidence without pretending that value-chain transformation belongs to one actor alone.

The endpoint must also be connected to cumulative emissions. A distant balance date does not compensate for high emissions in the intervening decades. Two pathways can both reach net zero in 2050 while producing very different warming because one cuts early and the other delays. Near-term absolute reductions are therefore part of the definition's integrity, not merely optional milestones.

Net zero is therefore best understood as a transition discipline rather than a badge.

It requires an organisation to know its full emissions profile, transform the sources it controls and influences, use removals cautiously and maintain transparency about what remains. The final balance matters, but the route determines whether the claim represents decarbonisation or arithmetic.

Practical application

Define the organisational boundary, gases, scopes, base year and target year. Publish gross emissions, reductions, removals and credits separately. Set near-term absolute targets for material sources and link capital expenditure, procurement and executive accountability to delivery. Create strict criteria for residual emissions and review them periodically.

Match neutralisation to durable removals, address double counting and report any temporary storage or avoided-emissions credits outside the net-zero balance. Explain how growth and structural changes are incorporated.

Why it matters

Net zero provides a common destination for limiting warming, but its flexibility allows weak claims to resemble strong ones. Clear boundaries and a reduction-first pathway determine whether the target drives transformation or postpones it.

Common misconception

Net zero is often interpreted as zero emissions or as permission to offset continuing emissions. It is a defined balance after deep reductions, with removals used for genuinely residual emissions rather than as a substitute for action.

Connections

Climate mitigation delivers the gross reductions required. Carbon sequestration and other removals may neutralise residual emissions. Greenhouse-gas accounting determines which gases and sources are included. Materiality helps identify whether the boundary omits the impacts that matter most.

A question worth asking

If removals and credits were unavailable, how much of your net-zero pathway would still be delivered through real reductions in gross emissions?
