TL;DR: A net zero target is a public commitment to reduce greenhouse gas emissions across an entity's full value chain to as close to zero as possible by a defined year, with any residual emissions neutralised through high-integrity removals. Setting one credibly requires a measured emissions baseline, Science Based Targets initiative-aligned near-term and long-term targets, a Scope 1, 2 and 3 reduction roadmap, and audit-ready disclosure under frameworks such as the CSRD, IFRS S2, and the SEC climate disclosure rule.

Key Takeaways

• 9,764 companies held validated science-based targets at the end of 2025 — a 40 percent year-on-year increase, according to the SBTi Trend Tracker 2025.

• 137 of 198 national governments (including the EU and Taiwan) have adopted a net zero target; 67 percent of those are now enshrined in law or formal policy, per the Net Zero Stocktake 2025.

• 63 percent of the Forbes Global 2000 carry net zero targets, covering $36.6 trillion in revenue (Net Zero Tracker, 2025).

• Only 7 percent of corporate net zero pledges meet minimum integrity criteria, and the median 2030 commitment cuts just 30 percent of full value chain emissions (NewClimate Institute Corporate Climate Responsibility Monitor 2024).

• Scope 3 supply chain emissions are on average 26 times greater than Scope 1 and 2 combined, yet only 15 percent of companies disclosing to CDP have set a Scope 3 target (CDP and BCG, 2024).

Introduction

Net0 is an AI infrastructure company that builds AI solutions for governments and global enterprises, with an AI-powered sustainability platform used by Fortune 500 firms and public-sector entities to set and execute net zero targets. This guide explains what a net zero target is in 2026, who is responsible for setting one, the five-step framework that makes a target credible, and how artificial intelligence is changing how large institutions plan, measure, and prove progress against their pledges.

The phrase "net zero target" is now embedded in corporate strategy decks and national legislation, but the underlying definitions vary widely. The Net Zero Tracker assesses 4,083 entities — countries, regions, cities, and the world's largest publicly listed companies — against ten integrity criteria, and finds that fewer than one in fifteen companies meet all of them. A target without a credible plan is, in the Tracker's words, "a slogan, not a strategy."

What is a net zero target

A net zero target is a binding commitment by a country, subnational government, company, or institution to bring its greenhouse gas emissions down to as close to zero as possible across its full operational and value chain footprint by a stated year, and to neutralise any unavoidable residual emissions using permanent removals.

Three terms are routinely confused and worth separating:

• Net zero balances residual emissions with permanent removals (afforestation, soil carbon, direct air capture with storage, mineralisation). The SBTi Corporate Net-Zero Standard requires at least 90 percent absolute emissions reduction across Scopes 1, 2 and 3 before neutralisation is applied.

• Carbon neutral typically refers to balancing operational emissions with offsets purchased on the voluntary carbon market. It is a weaker claim than net zero and does not require a value chain reduction trajectory.

• Climate positive / carbon negative means removing more emissions than the entity emits — a goal a small number of companies (Microsoft, IKEA, Ørsted) have publicly adopted.

For an extended primer on the definitional landscape, see Net0's explainer on what net zero actually means in practice.

The 2026 net zero target landscape

National-level coverage of net zero pledges has shifted in 2025. The Net Zero Stocktake 2025 reports that 137 of 198 national governments now have net zero targets, covering 77 percent of global GDP. The figure dropped from 93 percent the previous year after the United States federal government formally abandoned its commitment, but 19 individual U.S. states retained their targets, lifting effective coverage back to 83 percent of GDP when subnational pledges are included.

Corporate target-setting accelerated faster than the political backdrop suggests. The SBTi crossed 10,000 validated companies in January 2026, having validated more than 2,800 new firms in 2025 alone. The number of corporates with validated near-term and long-term net-zero targets — the strongest tier under the Corporate Net-Zero Standard — rose 76 percent year on year, from 980 to 1,729.

Disclosure rules are also locking the targets in. The Corporate Sustainability Reporting Directive (CSRD) requires roughly 50,000 companies operating in the EU to disclose Scope 1, 2 and 3 emissions and transition plans against ESRS standards. IFRS S2 is being adopted as the global baseline for climate-related financial disclosure, while the SEC climate disclosure rule and California's SB 253 and SB 261 push U.S.-active firms toward audit-grade emissions reporting. A net zero target without compliant data behind it is increasingly a regulatory risk, not just a reputational one.

How to set a credible net zero target

A net zero target is only as credible as the plan that sits behind it. The five steps below are derived from the SBTi Corporate Net-Zero Standard, the GHG Protocol, the IPCC's Net Zero by 2050 trajectory, and the integrity criteria used by the Net Zero Tracker.

Step 1: Build a complete GHG inventory

Measure Scope 1, 2 and 3 emissions for the latest reporting year using the GHG Protocol. Scope 3 alone covers 15 categories — purchased goods, capital goods, business travel, use of sold products, end-of-life — and on average accounts for around 75 percent of a corporate footprint, rising above 90 percent for consumer goods and apparel sectors (CDP, 2024). For deeper guidance on category breakdowns and methodologies, see Net0's articles on Scope 1, 2 and 3 emissions and Scope 3 in depth.

Step 2: Set near-term and long-term targets aligned to 1.5 °C

The SBTi requires a near-term target covering Scopes 1, 2 and 3 over five to ten years, plus a long-term target reaching at least 90 percent absolute reduction by 2050 (or 2040 for power, transport, and buildings sub-sectors). Targets must be expressed in absolute emissions terms — intensity targets alone are not accepted at the long-term tier.

Step 3: Build a Scope 1, 2 and 3 reduction roadmap

A target without sequenced abatement levers is what the Net Zero Tracker calls "ambition without action." A credible roadmap maps each emissions source to a specific lever (energy efficiency, electrification, on-site renewables, PPAs, supplier engagement, product redesign, modal shift in logistics, refrigerant swaps), assigns capital and timing, and uses a marginal abatement cost curve to sequence the cheapest, highest-impact actions first. See Net0's analysis of profitable decarbonization strategy for the financial case.

Step 4: Treat residuals with high-integrity removals

Under the SBTi standard, only the final 10 percent or less of unabated emissions can be neutralised, and only through permanent removals — not avoidance offsets. The 2024 Corporate Climate Responsibility Monitor found that more than a quarter of major companies plan to lean on removals, but only 4 percent had set a dedicated removal target with transparent volumes, raising integrity concerns.

Step 5: Govern, disclose, and verify

Hard-wire the target into board-level governance, link executive remuneration to delivery, and disclose annually under the regulatory framework that applies — CSRD, IFRS S2, SEC climate disclosure, or CDP. Independent assurance of the inventory and progress data is now expected by major investors and is mandatory under CSRD limited-assurance requirements.

Who sets and owns net zero targets

Net zero is not the sole responsibility of any one actor. Effective progress depends on three reinforcing layers: governments setting the policy and price signals, enterprises decarbonising their own operations and value chains, and subnational governments and communities anchoring local action.

Governments

National governments set the legal and fiscal frame: net zero laws, carbon pricing, sectoral standards, public procurement rules, and the redirection of subsidies away from fossil-intensive sectors. Public-sector spending alone accounts for between 18 percent and 47 percent of GDP in major economies (McKinsey, Decarbonizing the public sector, 2023), giving governments enormous leverage as a buyer. The Net Zero Stocktake 2025 finds that 67 percent of national net zero targets are now anchored in law or formal policy — up from 52 percent the previous year — but only 19 of the G20 currently maintain a target.

Enterprises

Companies are responsible for the majority of measurable global emissions and are the layer where targets translate into operational change. The 1,245 Forbes Global 2000 firms with net zero targets cover $36.6 trillion in revenue. However, two-thirds of those companies (860 of 1,245) back the target with a transition plan; the rest do not. Within the corporate boundary, a credible net zero plan must address both direct operations and the upstream supply chain, where most emissions sit.

Subnational governments and communities

Cities, states, and regions are increasingly the layer where infrastructure decisions get made. Subnational targets now cover 2.55 billion people — a fivefold increase since 2020. Live examples include the City of Berkeley, California, which has committed to community-wide carbon neutrality by 2045; Copenhagen, one of the first capital cities to legislate carbon neutrality; and Adur and Worthing Councils in the UK, targeting net zero by 2030 across council operations.

Why most net zero targets fail

The 2024 Corporate Climate Responsibility Monitor evaluated 51 of the world's largest companies against good-practice integrity criteria and found that none achieved a "high integrity" rating. The median 2030 reduction commitment, when adjusted for excluded emission sources, translated to just 30 percent of full value chain emissions — far below the 50 percent reduction by 2030 required for a 1.5 °C trajectory. Three failure modes recur:

1. Boundary gaming. Companies set headline net zero pledges that quietly exclude major Scope 3 categories, financed emissions, or product use-phase emissions. Walmart, Duke Energy, KEPCO, and Fast Retailing were assessed as committing to reduce only 5 to 20 percent of their full footprint by 2030 (NewClimate, 2024).

2. Reliance on offsets in place of reductions. Many pledges substitute carbon credits for actual abatement. The SBTi standard restricts neutralisation to the final 10 percent of residuals; targets that exceed this threshold without disclosure typically fail integrity assessments.

3. Weak data foundations. Twenty-five percent of disclosing companies factor supply chain climate risk into their risk management process (CDP, 2024), and most still rely on spend-based estimates for Scope 3. Without primary supplier data, a reduction trajectory cannot be verified — and increasingly cannot be assured under CSRD or IFRS S2.

How AI is changing net zero target-setting and execution

The 2021-era playbook — manual spreadsheets, annual emissions reporting, consultant-led baselines — cannot service the data volumes that CSRD, IFRS S2, and SBTi v2 now require. AI is the operational answer for institutions that need to measure across thousands of facilities and tens of thousands of suppliers, simulate decarbonization pathways, and report in audit-grade form on a continuous basis.

Specifically, AI is now used at institutional scale to:

• Automate emissions data collection from ERP, procurement, fleet, building management, and supplier systems — replacing manual data requests with structured ingestion across thousands of integration endpoints.

• Apply emission factors at line-item granularity using natural-language classification models that map purchased goods and travel records to GHG Protocol categories and the most accurate available emission factor.

• Run scenario modelling and marginal abatement cost analysis to quantify the carbon and financial impact of switching fuels, suppliers, or processes — and to sequence interventions for the most profitable decarbonization roadmap.

• Cascade Scope 3 data collection by inviting thousands of suppliers into a structured workflow with automated reminders, primary-data validation, and supplier-specific carbon footprints.

• Generate audit-grade disclosures mapped to CSRD, ESRS, IFRS S2, SBTi, GHG Protocol, CDP, GRI, and SEC requirements from a single dataset.

For a detailed view of how this applies in practice, see Net0's writeup on AI-driven sustainability data intelligence.

How Net0 helps enterprises and governments hit net zero targets

Net0 is used by 400+ entities across four continents, including Fortune 500 companies and government bodies, to set and operationalise net zero targets at institutional scale. The platform combines the AI infrastructure required for continuous measurement with the reporting depth required for compliance.

The Net0 sustainability platform covers the full target lifecycle:

• 10,000+ system integrations for automated data collection across operations, finance, HR, fleet, energy, and supplier systems.

• 50,000+ emission factors maintained across regions, vintages, and methodologies, mapped automatically to activity data.

• 30+ reporting frameworks supported out of the box, including GHG Protocol, CSRD / ESRS, IFRS S2, SBTi, CDP, GRI, SECR, and the SEC climate disclosure rule.

• Marginal abatement cost simulation and financial scenario modelling to identify the cheapest path to a 1.5 °C-aligned trajectory.

• Supplier outreach workflows that scale to tens of thousands of vendors and capture primary upstream emissions data.

• Sovereign and hybrid deployment for government and regulated industry customers — Net0 builds the same AI infrastructure for national-scale public sector AI transformation, where data residency and control are non-negotiable.

This is the same AI infrastructure that powers Net0's broader work in sovereign AI, custom enterprise AI models, and government program delivery. Sustainability is one vertical among several — but for the institutions setting net zero targets in 2026, it is increasingly the proving ground for whether AI infrastructure can deliver measurable, audited, defensible outcomes.

Frequently asked questions

What is the difference between net zero and carbon neutral?

Net zero requires reducing greenhouse gas emissions across the full value chain — Scope 1, 2 and 3 — to as close to zero as possible, with any residual emissions neutralised through permanent removals. Carbon neutral typically refers to balancing operational emissions with purchased offsets and is a less stringent standard. The SBTi Corporate Net-Zero Standard requires at least 90 percent absolute emissions reduction before residuals can be neutralised.

When should an organisation set its net zero target year?

Most credible standards point to 2050 at the latest, with sector-specific exceptions. SBTi requires power, transport, and buildings sub-sectors to reach net zero by 2040. Companies should set a near-term target covering five to ten years and a long-term target hitting 90 percent absolute reduction by 2050, in line with the IPCC 1.5 °C trajectory.

How does the Science Based Targets initiative validate a target?

The SBTi reviews submitted targets against its sector-specific decarbonization pathways, the Corporate Net-Zero Standard, and the SBTi Criteria. Targets covering Scopes 1, 2 and material Scope 3 categories that align with a 1.5 °C trajectory are validated and listed on the public dashboard. By the end of 2025, 9,764 companies held validated science-based targets.

What counts as a high-integrity residual emissions strategy?

Permanent removals — afforestation with durability safeguards, soil carbon with monitoring, direct air capture with geological storage, enhanced weathering, and biomass with carbon capture and storage — qualify under SBTi rules. Avoidance-based offsets do not. Volumes should be disclosed transparently and represent no more than 10 percent of the baseline year footprint at the long-term target year.

Do governments need different net zero targets than companies?

Governments target whole-economy emissions across all sectors, citizens, and territorial activity, and rely on policy levers — pricing, regulation, public procurement, subsidy reform — to drive change. Companies target their own operational and value chain emissions and rely on capital allocation, supplier engagement, and product redesign. The frameworks differ, but both are now expected to publish transition plans, not just headline targets.

How does AI accelerate net zero target-setting?

AI automates the parts of target-setting that scale poorly with manual effort: ingesting emissions data from thousands of operational systems, classifying line-item activities to the correct GHG Protocol category, simulating decarbonization scenarios, cascading data collection across supplier networks, and producing audit-grade disclosures across multiple frameworks. The result is a continuous, defensible measurement and planning capability rather than an annual reporting exercise.
