The Science Based Targets initiative (SBTi) has published Version 2.0 of its Corporate Net-Zero Standard, establishing an updated framework for companies to set, implement and assess science-based emissions reduction targets consistent with achieving net zero by 2050 or sooner. The revised standard introduces a more implementation-focused approach, requiring stronger governance, board-level accountability and transition planning, while differentiating requirements according to company size and geography through Category A and Category B classifications. It replaces the historical base-year approach with the use of the most recent representative emissions data, requires greenhouse gas inventories aligned with the Greenhouse Gas Protocol (GHG Protocol), and introduces enhanced transparency, reporting and assurance requirements, particularly for larger companies. Companies must set separate targets for scope 1 and scope 2 emissions, while Category A companies must also address material scope 3 emissions through emissions reduction, supplier-alignment, customer-alignment or activity-specific approaches. Net-zero targets remain optional but require comprehensive near-term and long-term targets across all emissions scopes and the neutralisation of residual emissions.
