Carbon neutral vs net zero: What’s the difference and why it matters  

“Carbon neutrality and net zero describe two fundamentally different relationships with emissions. One balances them. The other eliminates them. That distinction now has direct consequences for how companies report, communicate, and position themselves with investors.”

Both terms appear regularly in annual reports, investor presentations, and supplier questionnaires. Board members use them. Customers ask about them. Communications teams put them on websites. “Carbon neutral” and “net zero” are treated by many as interchangeable. They are not the same, and the gap between them is growing in both legal and strategic significance. 

The distinction matters to finance teams and ESG leads because of what it means for the credibility of external claims, the accuracy of regulatory disclosures, and exposure to greenwashing litigation. From September 2026, one of those terms carries a specific legal prohibition in the European Union when applied to consumer-facing marketing based on offsets. Understanding the difference before that deadline is a compliance requirement, not a point of nuance. 

What “carbon neutral” means 

Carbon neutrality refers to a state in which the carbon dioxide emissions associated with an entity’s activities are balanced by an equivalent quantity of carbon removal or offsetting. In practice, a company measures its emissions, purchases carbon credits to counterbalance them, and claims that the net result is zero. 

The standard governing carbon neutrality claims is ISO 14068-1:2023, which replaced BSI PAS 2060 on 1 January 2025 [1]. ISO 14068 requires a GHG inventory, a carbon neutrality management plan, and the use of verified carbon credits to offset remaining emissions. It sets no minimum level of actual emission reduction before offsets can be applied. A company that purchases sufficient credits with no internal reduction can, under ISO 14068, make a carbon neutrality claim. 

Carbon neutral claims typically focus on carbon dioxide, sometimes expressed as CO2 equivalents. Coverage of other greenhouse gases varies by claim and is not always made explicit. Scope 3 value chain emissions are frequently excluded. 

The term “carbon neutral” operates similarly. From 27 September 2026, the EU’s Empowering Consumers for the Green Transition (ECGT) Directive will prohibit consumer-facing claims of “climate neutral” where those claims rely on carbon offsets rather than actual emission reductions [2]. Companies with offset-based neutrality claims on consumer products, packaging, or digital marketing in the EU must review those claims before that date. 

What “net zero” means 

Net zero, as defined by the Intergovernmental Panel on Climate Change (IPCC), is achieved when human-caused greenhouse gas emissions are balanced by removing the same quantity from the atmosphere [3]. At the company level, the Science Based Targets initiative (SBTi) has translated this into a precise corporate standard. 

Under the SBTi Corporate Net-Zero Standard V1.3, corporate net zero requires: 

1. Reducing Scope 1, 2, and 3 GHG emissions by at least 90% from the base year, in line with a 1.5°C-aligned pathway, by no later than 2050 [4] 

2. Permanently neutralizing any residual emissions (up to 10% of base year) using high-quality carbon removals, after the 90% reduction is achieved [4] 

The sequence is fundamental. Deep emission reductions come first. Neutralisation of what remains is a final step, applied only to what is genuinely impossible to eliminate. Carbon credits serve this final neutralization function. They do not replace the reduction requirement. 

Net zero covers all greenhouse gases (carbon dioxide, methane, nitrous oxide, and others) across the full value chain. Scope 3 emissions are included. The SBTi does not validate carbon neutrality claims and explicitly states that offset-based approaches do not align with what climate science requires to limit warming to 1.5°C [3]. 

Five differences that determine legal and strategic exposure 

The two terms diverge across five dimensions that matter for corporate risk management and reporting. 

• Gases covered: Carbon neutral claims typically address carbon dioxide or CO2 equivalents, with variable scope across other gases. Net zero covers all seven greenhouse gases recognized under the Kyoto Protocol, across the full value chain, with no exclusions. 

• Role of offsets: Under carbon neutrality, offsets can substitute for emission reductions. A company can achieve a carbon neutral claim by purchasing sufficient credits without any operational change. Under the SBTi net-zero standard, offsets are only applied to residual emissions that remain after a 90% reduction, using permanent carbon removals [4]. 

• Minimum emission reduction required: ISO 14068-1 sets no minimum reduction threshold before offsets can be applied. Net zero requires at least 90% reduction from the base year before neutralization of residuals begins [4]. 

• Scope of coverage: Carbon neutral claims frequently exclude Scope 3 value chain emissions, which for most companies represent the largest share of their total GHG footprint. Net zero under the SBTi covers Scope 1, 2, and 3. Where Scope 3 exceeds 40% of total emissions, a Scope 3 science-based target is mandatory [4].

• Verification standard: Carbon neutrality claims can be verified under ISO 14068-1. Net zero targets can be validated by SBTi, which applies the Corporate Net-Zero Standard and publishes verified company targets on its public dashboard. SBTi validation is recognized in investor ESG questionnaires, CDP disclosures, and CSRD ESRS E1 reporting. 

What the ECGT Directive means for companies using offset-based climate claims 

The Empowering Consumers for the Green Transition (ECGT) Directive entered into force in March 2024 and must be transposed into national law across EU member states by 27 March 2026. Member states apply the new rules from 27 September 2026 [2]. 

From that date, generic environmental claims, including “climate neutral,” “carbon neutral,” “eco-friendly,” “green,” and “environmentally friendly”, are prohibited in consumer-facing communications unless substantiated by evidence meeting the directive’s requirements [2]. Requirements include clear, objective verifiable commitments, a detailed and realistic implementation plan, regular verification by a third party and public disclosure. Claims based on carbon offsets alone, without genuine underlying emission reductions, will not meet that standard. 

Companies using offset-based “carbon neutral” or “climate neutral” language on product packaging, websites, or marketing materials in EU markets must assess those claims before September 2026. The exposure applies to product labels and brand-level claims in investor communications, annual reports, and press materials, depending on how they are framed. 

The ECGT applies primarily to B2C claims, although the transposition of the Directive into country legislation varies on this principle. The Green Claims Directive, currently in the legislative process, will extend verification requirements further to specific environmental claims [2]. For companies operating across B2B and B2C channels, the combined regulatory direction is unambiguous: claims require substantiation, and offset-reliance without underlying reduction is the primary target of enforcement. 

For finance teams, this regulatory shift intersects with the accuracy requirements of CSRD ESRS E1.  

Sustainability disclosures must be verifiable and free from misleading characterization. A “carbon neutral” claim in an annual report that relies on offsets, without disclosure of that dependency, creates assurance risk in the first CSRD reporting cycle. For a full breakdown of what CSRD requires on climate targets and disclosures, the Nexio Projects reporting guide covers the reporting obligations in detail. 

How to position your business correctly 

The first step is precision about where the company currently stands. 

A company that has purchased carbon credits to offset some or all of its emissions holds a carbon neutrality position, not a net-zero position, regardless of the language used in its communications. If that language needs to change to comply with ECGT, the review should begin now. 

When “carbon neutral” is used loosely as a proxy for climate leadership, without clarity about the underlying evidence or a clear transition plan, it becomes a liability 

For companies setting a long-term climate commitment, a validated SBTi net-zero target provides investor-grade credibility that carbon neutrality alone cannot. Validated targets are publicly listed on the SBTi dashboard, science-aligned, and reviewed against the Corporate Net-Zero Standard. They fulfil the primary evidence requirements for ESRS E1 climate mitigation disclosures under CSRD and carry direct weight in CDP and EcoVadis assessments. 

The two positions are not mutually exclusive. A company can hold a documented ISO 14068 carbon neutral position as an annual interim claim while working toward an SBTi-validated net-zero commitment on a longer trajectory. The discipline is keeping the language of each claim accurate and distinct, and ensuring that interim offset activity is never presented as equivalent to the structural decarbonisation that net zero requires. 

For companies that have not yet completed a GHG inventory, Why get support with your corporate carbon footprint explains the data requirements and why the quality of that foundation determines everything that follows. For companies considering a net-zero commitment, SBTi in 2026: the road to net zero and compliance maps the validation process, Scope 3 obligations, and connection to CSRD. The quantified business case for acting now is set out in Science-Based Targets: the competitive advantage case is now settled. 

Carbon neutral and net zero describe two different relationships between a company and its emissions. Carbon neutrality balances emissions with offsets. Net zero eliminates them first, with offsets reserved only for what cannot be eliminated after deep reduction. 

That distinction now has legal, regulatory, and investor consequences. Companies with consumer-facing offset-based climate claims must review them against the ECGT Directive before September 2026. Companies preparing CSRD disclosures must apply the correct terminology with substantiated evidence behind each claim. Companies communicating with investors and lenders must be clear about whether their commitment is to periodic neutrality or to a science-aligned, long-term net-zero trajectory. 

Getting the language right is a risk management decision. 

Key takeaways: 

• Carbon neutrality balances emissions through carbon credits or offsets. Net zero requires reducing emissions by at least 90% first, with permanent removals applied only to residuals. They are structurally different commitments. 

• ISO 14068-1:2023 replaced BSI PAS 2060 on 1 January 2025 as the standard governing carbon neutrality claims. It sets no minimum emission reduction threshold before offsets can be applied. 

• From 27 September 2026, the EU’s ECGT Directive prohibits consumer-facing “climate neutral” and “carbon neutral” claims based on carbon offsets without substantiated underlying reductions. Companies with these claims in EU markets must review them before that date. 

• Net zero under the SBTi Corporate Net-Zero Standard V1.3 covers all GHGs across Scope 1, 2, and 3. Carbon neutrality claims frequently exclude Scope 3 and may focus on CO2 alone. 

• The two positions can coexist. ISO 14068-1 carbon neutrality can serve as a documented interim position while a company works toward an SBTi-validated net-zero target. The discipline is accuracy: the language of each claim must reflect exactly what has been reduced and what has been offset.
