Science-based targets and Net Zero: setting a target you can actually report against

Near-term targets vs Net Zero targets — two different commitments

The Science Based Targets initiative (SBTi) validates two distinct types of target, and conflating them is one of the most common mistakes in corporate net-zero communications:

• Near-term targets — emissions reduction targets for 5–10 years out, aligned to a 1.5°C pathway, covering Scope 1, Scope 2 and (where material) Scope 3. This is the target most organisations set first, and it's the one that actually drives near-term operational decisions.
• Net Zero targets — a long-term commitment (by 2050 at the latest) to reduce emissions by at least 90% against a base year across the whole value chain, with any small residual addressed through permanent carbon removal — not offsetting business-as-usual emissions with cheap credits. A validated Net Zero target requires a validated near-term target as a foundation; you can't credibly claim the long-term commitment without the near-term pathway underneath it.

A target that skips straight to "Net Zero by 2050" with no near-term milestone is exactly the kind of commitment sustainability scrutiny (and increasingly, procurement due diligence from larger customers) treats as unsubstantiated.

Scope coverage — where organisations quietly under-claim

SBTi sets minimum coverage requirements, and the most common way an otherwise well-intentioned target undersells its own credibility is incomplete scope coverage:

For most organisations outside heavy industry, Scope 3 is by far the largest share of total emissions — often 70–90% for a services or property-heavy portfolio. A target that only addresses Scope 1 and 2 because Scope 3 data is harder to gather is addressing the smaller part of the problem, and increasingly reads that way to anyone checking the target's scope statement rather than just its headline percentage.

Choosing a base year and an ambition rate

Two decisions determine whether a target is genuinely achievable or quietly set up to fail:

• Base year — the year against which reductions are measured. It needs a complete, defensible emissions inventory; picking an unusually high-emissions year to flatter the percentage reduction (or an unusually low one that makes the target trivially easy) undermines credibility either way. A recent, data-complete year is the safest choice.
• Ambition rate — the annual percentage reduction the target implies. SBTi's absolute contraction approach for a 1.5°C-aligned near-term target generally implies roughly 4.2% per year for Scope 1 and 2 (the exact figure depends on the pathway and sector); Scope 3 targets can use either an absolute or an intensity-based approach depending on data maturity.

The ambition rate is where targets most often diverge from reality: a target set to satisfy a validation threshold, without checking it against what the organisation's actual capital and operational plans can deliver, becomes a number nobody can report against honestly by year three.

Reporting against the target — the part that actually matters

Setting a validated target is the easy half. Reporting against it credibly, year after year, requires:

• Per-scope tracking against the trajectory line, not just a single combined percentage — a Scope 1/2 target well ahead of schedule can mask a Scope 3 target badly behind, and a combined figure hides that.
• Real consumption data, not modelled estimates, wherever it exists — a target tracked against estimated billing rather than metered/invoiced consumption drifts from reality quietly, and the gap only surfaces when a proper reconciliation eventually happens.
• A documented methodology that doesn't change year to year without explanation — switching calculation approaches between reporting years, even for good reasons, needs a stated restatement note or the trend line becomes meaningless.
• Honest treatment of any Scope 3 flag or gap — if full Scope 3 coverage isn't yet achievable, say so explicitly and show the roadmap to close it, rather than quietly reporting only what's easy to measure.

This is where a target genuinely lives or dies against operational reality — a validated commitment sitting in a PDF, disconnected from the actual monthly consumption and invoice data the organisation already collects, tends to quietly stop being reported against once the initial announcement has landed. On the Pro plan, EnergyIQ's Science Based Targets page plots an indicative near-term and Net Zero pathway against your actual Scope 1 and 2 emissions, and flags when a Scope 3 target is likely to be required (it is indicative planning, not an SBTi assessment; only the SBTi validates a target) — so the reported position each year reflects what actually happened.

Common mistakes

1. Announcing "Net Zero by 2050" with no validated near-term target underneath it.
2. Excluding Scope 3 by default rather than assessing whether it clears the 40% materiality threshold.
3. Picking a base year for its flattering percentage rather than its data completeness.
4. Setting an ambition rate that satisfies a validation threshold but doesn't match actual capital/operational plans.
5. Tracking progress against modelled estimates instead of reconciling to metered and invoiced consumption once it's available.
6. Changing calculation methodology between years without a restatement note, breaking the trend line's credibility.
