WEO 2025 presents two exploratory policy scenarios side by side, the Current Policies Scenario (CPS, reintroduced) and the Stated Policies Scenario (STEPS). Neither is named the main scenario. STEPS is marked main_scenario for continuity with 2019-2024; CPS rows are marked main_scenario false by field below. The Net Zero Emissions scenario is not captured. No target year before 2035 in Annex A (the annex jumps from 2024 to 2035). Annex text licence: CC BY-NC-SA 4.0.
