The G3W outlook covers the G3W Implementation and Pre-operational Phase (G3W-IPP) in the financial period 2024-2027 with the first two years dedicated to ramp up the human and financial resources required, both in the WMO Secretariat and in the Operational Centres, so that the entire chain is interlinked and set in motion and keys observational assets are becoming available with agreed standards. It is envisaged that the G3W-IPP will embed substantial progress and adjustment to achieve and/or gain efficiency.
The G3W Initial Operational Phase (G3W-IOP) begins in the next financial period (2028-2031), and it includes the consolidation of the G3W systems configuration for the 2nd GST which is a key moment in the Paris Agreement Enhanced Transparency Framework (PA-ETF), since it will permit to measure progress with respect to the 1st GST.
The G3W-IOP will be at service of the Nations in setting new NDCs and evaluating the uncertainties in the assessment of the GHGs growth/abating rates. Within the G3W-IOP in 2030 an extensive assessment of the state of climate change mitigation shall be produced to guide the requirements and ambitions of the Enhanced Operational Phase G3W-EOP, in full compliance with the needs of the PA-ETF.
The G3W-EOP will aim at providing actionable information assisting the Nations, Parties to the United Nations Framework Convention on Climate Change, in their LT-LEDS, providing also support for the long-term horizon of the NDCs with the ambitions of tackling the climate and inequality crises at the same time, so that no one is left behind.
There is a lot of activities that have to be implemented beyond the initial 4 years. These are related to enhancement of the observational and modelling capabilities. Many of those actions are cover ocean and terrestrial domain as the initial focus of G3W is on getting net fluxes.
The detailed outlook for the specific components of G3W is presented in the full Implementation Plan.
