Net zero has gone from corporate buzzword to boardroom commitment. But what does it actually take for a business to decarbonise credibly — and how can stakeholders tell the difference between strategy and spin?
What “Net Zero” Really Means (and Why It’s Not a Slogan)
At the global level, “net zero emissions” means balancing human-caused greenhouse gas emissions with human-led removals over a specified period. In other words: emissions still occur, but removals counterbalance what remains. The Intergovernmental Panel on Climate Change (IPCC) uses this definition explicitly in its glossary: net zero emissions are achieved when emissions are balanced by removals.
For companies, this matters because the phrase “net zero” can be used in two very different ways:
- As a measurable decarbonisation trajectory (deep reductions first, removals for small residuals).
- As a marketing story (offset-heavy “neutrality” claims without meaningful cuts).
If you want a quick rule: a credible net-zero plan is mostly about cutting emissions in the real economy — not buying your way around them.
Scopes 1, 2, and 3: The Accounting That Makes Net Zero Testable
Before you can reduce emissions, you have to measure them consistently. Most corporate emissions reporting uses the Greenhouse Gas (GHG) Protocol’s scope framework. At a high level, the GHG Protocol Corporate Standard is the core reference for organisational inventories (GHG Protocol Corporate Standard (PDF)), and Scope 3 has its own value chain standard (Corporate Value Chain (Scope 3) Standard (PDF)).
In plain terms:
- Scope 1: direct emissions from sources a company owns or controls (e.g., onsite fuel combustion, company vehicles).
- Scope 2: indirect emissions from purchased electricity, heating, cooling, or steam.
- Scope 3: all other indirect emissions across the value chain (suppliers, logistics, product use, end-of-life, business travel, investments, and more).
Scope 3 is the hard part because it’s dispersed across suppliers, customers, and infrastructure you don’t directly own. If you want a plain-language primer from Unsustainable’s archive, see Scope 3 emissions: how companies can reduce carbon impacts.
Scope 3 also explains why decarbonisation is often less visible than people expect: many impacts happen “outside the fence line.” A strong example (in a different sector) is construction, where embodied carbon lives in global supply chains — carbon emissions in construction breaks down how upstream emissions can dominate what’s visible onsite.
What a Credible Net-Zero Pathway Looks Like in 2026
It’s tempting to think net zero is mainly about renewable energy and EVs. In practice, a credible pathway is an organisational project: measurement, governance, procurement, capital allocation, and accountability — plus a lot of unglamorous operational work.
1) Start with a complete emissions inventory
A plan that begins with vague estimates or partial boundaries is hard to trust. Credible approaches establish a full company-wide inventory (Scopes 1 and 2, and a complete Scope 3 inventory) using recognised standards such as the GHG Protocol (Corporate Standard (PDF) and Scope 3 Standard (PDF)).
2) Set targets that require deep cuts — not just distant promises
The Science Based Targets initiative (SBTi) is widely used for corporate target-setting aligned with climate science. The SBTi’s Corporate Net-Zero Standard and its accompanying guidance (science-based targets 101: near-term and net-zero) make two expectations especially clear:
- Companies need near-term targets (typically 5–10 years) and a long-term target.
- Long-term targets require at least 90% emissions reductions before relying on neutralisation/removals, and must cover the vast majority of Scope 1 and 2 emissions and a large share of Scope 3 (SBTi guidance).
For detail on the inventory and boundary expectations, the SBTi’s standard document is explicit (SBTi Net-Zero Standard (PDF)).
3) Prioritise real reductions, then use credits carefully (if at all)
Offsets and carbon credits are not automatically “bad,” but they are frequently abused. A credible corporate approach treats credits as supplementary and applies quality screens that are public, consistent, and conservative.
Two integrity frameworks are widely referenced in the voluntary carbon market:
- ICVCM Core Carbon Principles (what “high integrity” credits should look like).
- VCMI Claims Code of Practice (how companies can make credible claims when using credits, without substituting for value-chain action).
If a company’s “net zero” story is mostly credit purchases and glossy claims, assume you’re looking at a risk — not a plan.
4) Treat procurement and the supply chain as climate strategy
For most companies, value-chain emissions dominate. That means procurement policies and supplier engagement are climate policy. In practice, credible strategies include:
- Supplier data requirements and category-level Scope 3 measurement.
- Low-carbon procurement standards (materials, logistics, energy, packaging).
- Long-term contracting that rewards verified emissions reductions.
- Product redesign to reduce downstream emissions (durability, repairability, efficiency, end-of-life).
These aren’t “nice-to-haves.” They are the mechanism by which Scope 3 becomes reducible rather than rhetorical. Again, Unsustainable’s Scope 3 guide is a useful entry point here.
5) Put governance and incentives where the emissions are
Net zero fails when it’s delegated to a sustainability page instead of embedded in operations and finance. Real pathways usually involve:
- Board oversight and clear accountability.
- Climate-related KPIs tied to executive incentives.
- Capex alignment (what gets funded, retrofitted, replaced, delayed, or stopped).
If you want to see how “sustainability” becomes measurable once it touches capital flows, Sustainable banking: where the money actually goes is a strong companion piece — it’s a reminder that claims are easy, but money movements can be traced.
Why Greenwashing Risk Is Rising (and Why That Changes Strategy)
As scrutiny increases, vague environmental claims become liabilities. The European Union has moved to restrict misleading “climate neutral” and similar claims that rely on offsetting, as part of broader consumer-protection and anti-greenwashing reforms (Reuters overview of the Empowering Consumers directive and related measures; see also the European Commission’s Green Claims policy page).
The direction of travel is clear: claims will need stronger substantiation, and “net zero” messaging will increasingly be judged by measurable progress — not just intent.
At the company level, this means a credible net-zero plan is also a communications discipline: specific language, clear boundaries, and public methods. If you want a business-oriented warning sign checklist, Unsustainable’s Building an ethical startup: embracing real sustainability covers the reputational and legal risks of sustainability claims that can’t be backed up.
What Progress Looks Like in the Real World (Not a Brochure)
In practice, decarbonisation often shows up as incremental upgrades: electrification, commuting changes, procurement shifts, retrofits, and process redesign. None of this is cinematic — which is why serious reporting matters.
There’s also a practical truth: decarbonisation competes with everything else a business does. The best plans are designed to survive that competition by building emissions reductions into operational defaults. Waste minimisation is a good example of how operational discipline can reduce costs and environmental impact at the same time — see benefits of waste minimization in business.
A Reader Checklist: How to Tell Substance from Sustainable Branding
- Do they disclose Scopes 1, 2, and 3? If Scope 3 is ignored, the plan is likely incomplete.
- Are there near-term targets with interim milestones? “Net zero by 2050” without a 2030 plan is a warning sign.
- Is the boundary clear and consistent? What’s included, excluded, and why?
- Do they prioritise reductions over offsets? Credible pathways cut first and treat credits conservatively (see ICVCM and VCMI).
- Is governance aligned? Board oversight, incentives, and capex alignment matter more than slogans.
- Do they show supply-chain strategy? Procurement and suppliers are where most emissions live.
- Is progress reported with methods, not just marketing? Credibility comes from repeatable measurement, not one-off headlines.
Net Zero Is a Direction, Not a Finish Line
Net zero is sometimes framed like a destination. In reality, it’s a trajectory — one that should be visible in inventories, procurement, governance, and investment decisions. The more the public conversation shifts from “claims” to “evidence,” the more valuable credible corporate action becomes.
Businesses that treat net zero as a real operational project — measured, governed, and financed — are more likely to deliver reductions that hold up under scrutiny. Everyone else will be competing in a tougher environment: tighter definitions, higher expectations, and less patience for offset-based storytelling.
