In short: A defensible carbon neutral claim goes through six steps: GHG Protocol-aligned measurement, a science-based target, reduction ranked by cost, neutralization of residual emissions only, audit-ready reporting, and governance tied to budget. The order of the steps decides whether the claim is credible.
1. Measure your footprint so it can be audited
Everything depends on the quality of the inventory. Start by drawing the organizational boundary: which legal entities, sites and joint ventures are included, and under which consolidation approach. Then fix the reporting period and assign a data owner to every emission source. The reference framework is the GHG Protocol Corporate Standard.
- Scope 1: Direct emissions from sources you own or control, including fuel burned in boilers and kilns, process emissions, company vehicles and refrigerant leaks.
- Scope 2: Indirect emissions from purchased electricity, steam, heating and cooling, reported under both the location-based and market-based methods.
- Scope 3: All other indirect emissions in the value chain, split into 15 categories, from purchased goods and logistics to business travel and use of sold products.
Don't leave Scope 3 for later. Companies reporting to CDP put their supply chain emissions at 26 times their operational emissions on average (CDP, 2024). Our Scope 3 emissions page explains where to start by category.
If you export to the EU, you need product-level data alongside the corporate inventory, because CBAM asks for embedded emissions by installation and product. Building both on the same dataset from day one saves you from reconciling two different numbers later.
2. Set a science-based target
A target only means something when it is tied to a base year, a defined boundary and a 1.5°C-aligned pathway. SBTi is the reference here. It published the Corporate Net-Zero Standard V2.0 on June 11, 2026. The new version takes effect on February 1, 2027, and V1 remains open for target setting until the end of 2027 (SBTi).
V2.0 has a few practical consequences. Every company must set near-term Scope 1 and 2 targets, while near-term Scope 3 targets are required from Category A companies, defined by turnover, headcount or emissions size. Credits do not count in place of reductions in the physical inventory.
Pick the base year carefully. It should reflect a normal operating year and rest on data you can still document. A long-term pledge without interim milestones binds no one. The near-term target is the one that shapes today's capital decisions.
3. Rank reductions by cost and speed
Build the reduction plan on marginal abatement cost logic: cheap, fast measures first, then structural investments timed to the asset replacement cycle.
- Energy efficiency: compressed air leaks, waste heat recovery, motor and drive upgrades, insulation and operating schedules. Paybacks are short, and the savings fund what comes next.
- Electrification and fuel switching: heat pumps for low-temperature process heat, fleet conversion and replacing fossil equipment at end of life. This moves emissions from Scope 1 into a Scope 2 that gets cleaner as the grid does.
- Renewable electricity: power purchase agreements or credible contractual instruments for the remaining Scope 2.
- Process, materials and logistics: yield gains, input substitution, circular materials, modal shift and load optimization.
- Supplier engagement: with most of Scope 3 sitting with suppliers, this is central to the plan, not an add-on.
Carbon pricing raises the stakes. In the EU, the ETS covers domestic producers and CBAM covers imports. Exporters' home markets are following: Türkiye's ETS Regulation, published on August 27, 2026 under Climate Law No. 7552, covers installations above 50,000 tCO2e a year.
4. Neutralize residual emissions only
Neutralization comes after reduction. It is a legitimate tool for emissions today's technology cannot remove. Applied to a footprint that was never seriously reduced, it mostly buys reputational risk. ISO 14068, the international standard for carbon neutrality, requires the same order. It was updated to ISO 14068:2026 in September 2026 and accepts offsetting only for the remaining footprint (ISO).
Screen credits against ICVCM's Core Carbon Principles (ICVCM):
- Additionality: would the project have happened without carbon revenue?
- Permanence: how is reversal risk covered?
- Robust quantification: is the baseline conservative?
- No double counting: is the same tonne claimed by anyone else?
- Independent verification and a transparent retirement in your name.
Size purchases to a shrinking inventory and shift the mix toward removals over time. SBTi V2.0 also expects residual emissions at the net-zero year to be neutralized with carbon removals.
5. Make reporting and claim wording audit-ready
Report in the frameworks your stakeholders already use. The GHG Protocol sets how the inventory is built. CSRD and the ESRS define what large EU companies disclose. Since Omnibus I, the scope is limited to companies with more than 1,000 employees and over €450 million in net turnover, but those companies still ask suppliers for data. CDP remains common in customer questionnaires. Feeding all of them from one dataset keeps three departments from publishing three different figures.
Independent assurance is what makes the number credible externally. Auditors want traceable activity data, emission factor sources, a written methodology and evidence of internal controls. Designing the data flow for that from the start costs far less than a last-week cleanup.
Wording matters as much as arithmetic. EU Directive 2024/825 has applied since September 27, 2026 and prohibits claiming that a product's greenhouse gas impact is neutral, reduced or positive on the basis of offsetting (EUR-Lex). Always report gross emissions, achieved reductions and neutralized volume as separate figures, and state which scopes are included.
6. Tie the program to budget and governance
A climate plan without a budget is just a document. Give the reduction program to the functions that control spending: operations, engineering, procurement and finance. Give it a standing line in the capital plan rather than a discretionary allocation that gets renegotiated every year.
Translate the target into metrics at the level where decisions are made, such as emissions per unit of output by site, renewable electricity share, fleet conversion rate and the share of suppliers providing primary data. Write carbon criteria into purchasing policy and supplier qualification.
Put the program under board oversight with a set reporting calendar and link it to enterprise risk management. Carbon IQ brings this data together at site and product level in one place.
What the six steps pay back
The first return is cost. Energy and material efficiency lowers operating expense directly, and in sectors exposed to emissions trading or CBAM, cutting emissions cuts a real and rising carbon cost. CBAM's definitive period began on January 1, 2026, and the first annual declaration for 2026 imports is due by September 30, 2027.
The second is access to markets and capital. Documented emissions data is becoming a qualification requirement in supply contracts for anyone selling into the EU, and verified climate performance opens the door to sustainability-linked finance.
The third is resilience. A company that knows its energy dependence, supplier concentration and carbon cost trend absorbs price shocks and regulatory change with less disruption. To see where your inventory sits across these six steps, talk to our team.
