Carbon neutral vs net zero: what the claims mean and how to spot greenwashing
A neutral guide to carbon neutral, net zero and climate positive claims, the standards behind them (ISO 14068, SBTi, UN HLEG) and India's 2024 greenwashing guidelines.
How are carbon neutral, net zero and climate positive different?
| Claim | What it usually means | Role of carbon credits | Main reference |
|---|---|---|---|
| Carbon neutral | Emissions for a period are measured, reduced where possible and balanced | Often large; credits balance what remains | ISO 14068:2026 (formerly ISO 14068-1:2023) |
| Net zero | Emissions cut by about 90% or more over time; only residual balanced with removals | Cannot replace own cuts; only removals for the residual | SBTi Corporate Net-Zero Standard; UN HLEG "Integrity Matters" |
| Climate positive or carbon negative | Claims to remove or balance more than the entity emits | Usually depends on credits or removals | No single recognised standard; treat with care |
| Offset | One unit of reduction, avoidance or removal made by someone else, bought to balance one unit of your emissions | It is the credit itself | IPCC AR6 glossary; carbon credit programme rules |
A simple way to remember it: carbon neutral is a balance sheet for one period; net zero is an end state reached through deep cuts.
