Carbon Neutral vs Net Zero — What's the Difference?
Quick answer: Carbon neutral and net zero are both terms for achieving zero carbon emissions, but net zero is more rigorous. Carbon neutral allows for unlimited use of carbon offsets to balance emissions, while net zero requires reducing emissions as much as possible first, and only using offsets for remaining emissions. Net zero also includes all greenhouse gases, not just carbon dioxide.
Definition of Terms
Carbon Neutral
Carbon neutral means achieving a balance between emitting carbon dioxide and absorbing it from the atmosphere. This can be done through:
- Reducing emissions
- Using carbon offsets (such as planting trees)
- Carbon capture and storage
Carbon neutral often focuses on carbon dioxide only, and there's no specific requirement for how much emissions must be reduced before using offsets.
Net Zero
Net zero is a more comprehensive and rigorous standard:
- Emission reduction first: Must reduce emissions by at least 90% before using offsets
- All greenhouse gases: Includes methane, nitrous oxide, and fluorinated gases
- Rigorous standards: Offsets must be high-quality and verifiable
- Long-term commitment: Requires a clear plan to phase out emissions entirely
Key Differences
| Aspect | Carbon Neutral | Net Zero |
|---|---|---|
| Emission reduction requirement | No minimum | At least 90% reduction |
| Greenhouse gases covered | Usually CO₂ only | All greenhouse gases |
| Offset quality | Variable | High-quality, verified |
| Rigorousness | Lower | Higher |
| Long-term goal | Balance emissions | Phase out emissions entirely |
Examples of Implementation
Carbon Neutral
A business might claim to be carbon neutral by:
- Calculating their annual emissions
- Offsetting all emissions through a tree planting project
- No significant reduction in their own operations
Net Zero
A company working towards net zero might:
- Set a science-based target to reduce emissions by 95% by 2050
- Invest in renewable energy and energy efficiency
- Implement carbon capture technology
- Offset remaining 5% with high-quality direct air capture
Which is Better?
Net zero is a stronger commitment and more aligned with climate goals. While carbon neutral can be a starting point, net zero is necessary to limit global warming to 1.5°C. The difference is similar to dieting: carbon neutral is like balancing calories by eating more and then burning them off, while net zero is like eating less first and only burning off a small amount.
Frequently Asked Questions
Can individuals be net zero?
Yes. Individuals can work towards net zero by reducing their emissions as much as possible and offsetting remaining emissions. Our calculator can help you understand your current footprint and what you can reduce.
What are high-quality offsets?
High-quality offsets are verified to be additional (would not have happened without the offset), permanent, and not double-counted. Examples include direct air capture and regenerative agriculture.
Is net zero achievable?
Yes, but it will require a rapid transition to renewable energy, improved efficiency, and investment in carbon removal technologies. The IPCC states that we need to reach net zero by 2050 to stay below 1.5°C.
