Science Based Targets (SBTi): How Corporate Climate Targets Get Validated

The Science Based Targets initiative (SBTi) is a partnership between CDP, UN Global Compact, WRI, and WWF. It validates that a company's climate targets are aligned with limiting warming to 1.5°C.

Over 8,000 companies have committed as of 2026. This guide covers what SBTi actually validates, the SME shortcut, and how to avoid the common submission failures.

What SBTi validates

Near-term targets (5–10 year horizon): typically 42% absolute reduction of +2 by 2030 versus 2019. target required if it exceeds 40% of total emissions.

Net-zero targets (2050 or earlier): >90% reduction across all scopes with residuals neutralized by permanent removals. Interim milestones required.

The SME route

For companies with <250 employees and outside high-impact sectors, SBTi offers a streamlined route: pre-approved target language, single-step validation, fixed low fee (~$1,000). No target required. Approval typically inside 60 days.

Common submission mistakes

Setting an intensity target when SBTi requires absolute. Missing the threshold check. Using a base year without documented data quality. Committing to renewables without a specific instrument (, , on-site).

FAQ

Frequently asked questions

Is SBTi mandatory?

No. But it's the credibility standard many customers, banks, and investors now expect.

How long does validation take?

SME route: ~60 days. Standard route: 6–9 months including revisions.

Can I use offsets to meet SBTi targets?

No. Offsets do not count toward SBTi reductions. Removals count only against residual emissions in net-zero targets.
