Net Zero Calculator
Plan a path to net-zero emissions by calculating required annual reductions and remaining offsets needed.

Residual Emissions at Target vs Years to Net Zero
Formula
## How to Plan for Net Zero Net zero means reducing emissions as much as possible and offsetting the remainder. ### Formula **Residual Emissions = Current * (1 - Annual Reduction %)^Years** **Offsets Needed = Residual Emissions** The Science Based Targets initiative requires at least 90% absolute reduction before relying on offsets for net zero. Remaining emissions must be neutralized through high-quality carbon removal.
Esempio Risolto
A company emitting 1,000 tons CO2e reduces 7% annually over 10 years with $30/ton offsets.
- 01Residual: 1,000 * (1 - 0.07)^10 = 1,000 * 0.484 = 484 metric tons
- 02Total reduced: 1,000 - 484 = 516 metric tons
- 03Offsets needed: 484 metric tons/year
- 04Offset cost: 484 * $30 = $14,520/year

What does net zero mean?
Net zero means that any greenhouse gases emitted are balanced by an equivalent amount removed from the atmosphere, resulting in no net increase in atmospheric CO2.
What reduction rate is needed for 2050 net zero?
To reach net zero by 2050 from current levels requires roughly 7-10% annual emission reductions, depending on starting point and how much residual can be offset.
What counts as a valid offset for net zero?
For SBTi net zero, only carbon removal offsets count (direct air capture, enhanced weathering, afforestation). Avoidance credits do not qualify for neutralizing residual emissions.
