Science-Based Target (model laws definition) meaning

In legal practice, a science-based target describes an organisation’s greenhouse gas emissions target calibrated to pathways for limiting global temperature rise to 1.5°C above pre‑industrial levels (and at minimum well below 2°C), in line with the Paris Agreement and current climate science. It is not defined in UK or Irish legislation or case law; rather, it is a descriptive term widely used in corporate governance, ESG disclosures, procurement, financing (including sustainability-linked loans and bonds) and transactional due diligence. Contracts and policies typically define the term by reference to the Science Based Targets initiative (SBTi) criteria (as amended from time to time). Key features usually include coverage of Scope 1 and Scope 2 emissions and, where material, Scope 3; a specified baseline year; a reduction trajectory consistent with a 1.5°C pathway; interim milestones; independent validation or assurance; periodic review and ratcheting if standards evolve; and reporting obligations. Legal consequences for failure to set, maintain or meet the target is addressed through covenants, KPIs, pricing adjustments, events of default or termination rights. Usage and market practice are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland, but individual instruments should define the term expressly.
