My Department has been working closely with the National Transport Authority (NTA) to deliver the Corrective Actions Modelling Project, the aims of which are threefold:
1. Identify potential pathways to correct the trajectory of carbon emissions from the transport sector out to 2030.
2. Identify whether any additional measures, above and beyond those required to keep the transport sector within its sectoral emissions ceilings, could be proposed to deliver currently unallocated savings for carbon budget period 2 (2026-2030).
3. Identify decarbonisation interventions and policy pathways that will continue to deliver sustained and accelerated emissions abatement beyond 2030 into Carbon Budget 3.
The detailed scope of this project was agreed between my Department and the NTA in late 2024 and there has been extensive engagement in 2025 with stakeholders to develop and define emissions abatement measures. The NTA’s models, including the Regional Modelling System and the Carbon Forecasting Tool, are being used to test new and existing AVOID – SHIFT – IMPROVE measures under three different scenarios for their potential impact on carbon emissions in the transport sector out to 2030 and 2035. A socioeconomic assessment is also underway alongside the scenario modelling work to evaluate the distributional, social and economic impacts of measures to ensure a just transition.
The Corrective Actions Modelling Project will inform future iterations of the Climate Action Plan and wider policy initiatives within the transport decarbonisation domain.
