SBTi is the common abbreviation of the Science Based Targets initiative, a global body that validates corporate greenhouse gas emissions reduction targets against climate science. SBTi was launched in 2015 by CDP, the UN Global Compact, the World Resources Institute (WRI) and WWF, and published the Corporate Net-Zero Standard in October 2021. The term “SBTi” is now commonly used both as the organisation’s name and as a shorthand for “SBTi-validated target”.

SBTi as a process moves a company from commitment to validation in four steps: (1) Commit — submit a commitment letter via the SBTi portal; (2) Develop — calculate a base year inventory under the GHG Protocol and design targets using SBTi methods; (3) Submit — file targets for SBTi technical review; (4) Disclose — publish validated targets and report annually on progress.
The Corporate Net-Zero Standard (October 2021) requires near-term science-based targets (typically 5-10 years), a long-term science-based target consistent with 1.5°C alignment by 2050 (or sooner), measurement and reduction of scope 3 emissions where they form more than 40% of the corporate footprint, and the neutralisation of residual emissions using durable carbon removals from no later than the long-term target year.[1]
SBTi distinguishes specialised methodologies by sector: financial institutions (under revision in 2024-25), oil and gas (issued 2024), forest, land and agriculture (FLAG, 2022), aluminium, apparel and footwear, automotive OEMs, buildings, cement, chemicals, ICT, maritime, power, real estate and steel.
SBTi has no statutory authority but enjoys regulatory recognition as a credible target-setting framework. The TCFD 2021 Guidance on Metrics, Targets and Transition Plans references SBTi alignment as a “well-recognised approach”.[2] IFRS S2 requires disclosure of how climate-related targets compare to the latest internationally accepted agreements; SBTi validation is a frequent answer.[3]
In the UK, the Companies Act 2006 s.414CB (introduced by SI 2022/31) requires large companies and LLPs to disclose principal targets used to manage climate-related risks and opportunities — many UK companies cite SBTi-validated targets.[4] The Occupational Pension Schemes (Climate Change Governance and Reporting) Regulations 2021 (SI 2021/839) introduced a portfolio alignment metric (Implied Temperature Rise) for which SBTi coverage of portfolio companies is a common input.
In April 2024, SBTi paused validations under the Financial Institutions Net-Zero Standard (FINZ) pending revisions; a draft revised standard is in consultation through 2024-25.
SBTi validation operates as a credibility signal across UK insurance practice. For underwriters of D&O, financial lines, EIL and credit insurance, an SBTi-validated near-term target is a strong indication of board engagement and credible transition planning. The major brokers (Aon, Marsh, WTW, Gallagher) cite SBTi status in submissions for industrial, energy, FMCG, real estate and financial services accounts.
UK insurer groups themselves have either validated SBTi targets or committed to do so. Aviva, Legal & General, Phoenix, M&G and Lloyd’s market participants have made public SBTi-related commitments. The PRA does not mandate SBTi alignment but recognises it under SS 3/19 governance and strategy expectations. Lloyd’s references SBTi alignment in its ESG reporting and in the Performance Management Directorate’s expectations on managing agents.
A UK business committing to SBTi should expect 12-24 months from commitment letter to validated target, depending on data quality and sector complexity. Critical pre-conditions are a GHG Protocol-aligned inventory (commonly built on CDP-style disclosure), board approval for the target ambition, and a transition plan addressing capex, opex and capability.
For insurance, SBTi validation is most useful when discussing D&O renewals, ESG-linked credit insurance, sustainability-linked surety, and any cover where transition planning is salient. It is also a powerful response to customer ESG questionnaires and procurement sustainability scoring.
A UK manufacturing group commits to SBTi in early 2024, completes a verified scope 1-3 baseline by Q4 2024 using CDP-style methodology, and submits targets in Q1 2025. The SBTi validates a 42% absolute scope 1 and 2 reduction by 2030 and a 52% scope 3 intensity reduction by 2030, with a net-zero target for 2045. The validation is published, referenced in the strategic report under s.414CB Companies Act 2006, and used by the broker to secure flat D&O renewal pricing in a hardening market.
