The National Planning Framework (NPF) First Revision governs Ireland's Government spatial growth, macroeconomic development, and public/private capital investment through the year 2040. The document updates population and housing projections planning for a baseline of 6.1 million by 2040. More Specific Compact Growth Targets were introduced (NPO 7, 8, & 9): NPO 7 maintains the national target of delivering at least 40% of all new homes within the built-up footprint of existing settlements, but the revision explicitly clarifies and refines the definition of "built-up footprint" based on artificial surfaces mapped during local zoning; NPO 8 mandates at least 50% of all new homes targeted for the five main cities (Dublin, Cork, Limerick, Galway, Waterford) be within their existing built-up footprints; NPO 9 targets at least 30% of new homes in all other settlements to be within their existing built-up footprints. Introduction of Transport-Orientated Development (NPO 10): A major new addition is National Policy Objective 10, which explicitly mandates the delivery of Transport Orientated Development (TOD) at scale. This focuses on building sustainable, high-density communities adjacent to high-capacity public transport corridors (especially rail) within the five cities and metropolitan areas to combat greenfield sprawl. Environmental Capacity Guidance (NPO 11): A new objective (NPO 11) dictates that individual development proposals on zoned land must look beyond rigid targets alone and explicitly prioritize the local "receiving capacity of the environment." The revision also updates the framework to align with the Climate Action and Low Carbon Development (Amendment) Act 2021 and the National Climate Action Plan 2024. This embeds the statutory commitment to reduce greenhouse gas emissions by 51% by 2030 and achieve net-zero emissions by 2050. It places a heavier focus on grid transmission and new energy systems (wind, solar, wave, biomass). It highlights utilizing publicly owned peat extraction areas to manage a "just transition" for local economies moving away from fossil fuels. It integrates the strategies of Zero Emission Vehicles Ireland (ZEVI) to coordinate a national EV charging network, aiming to push the proportion of electric vehicles in the national car fleet to 30% by 2030. New emphasis is placed on water conservation (like rainwater harvesting) and "Nature Based Solutions" to free up capacity in existing urban combined sewer networks. The revision reflects the establishment of the independent Office of the Planning Regulator (OPR) in 2019, which now legally monitors the implementation of the NPF. Moreover, it includes the establishment of the Land Development Agency (LDA) and ongoing legislative planning reforms designed to use State-owned lands as a catalyst for urban regeneration. Following recommendations from a 2023 Expert Group, a new data tool is being developed to strictly track, measure, and compare urban footprint growth versus outward greenfield "land take" across all major settlements.
