The CO₂ Performance Ladder is a sustainability instrument developed by SKAO to help organisations reduce greenhouse gas emissions across their operations, projects, and supply chains.
Handbook 4.0 introduces a new structure with three steps instead of five levels, focusing on measurable results and alignment with international climate goals. Organisations must demonstrate insight into emissions, set reduction targets, and implement a Climate Transition Plan towards net-zero by 2050.
Certification continues to be based on four principles: Insight, Reduction, Transparency, and cooperation, but now includes stricter requirements for data quality, governance, and long-term decarbonisation.
