I thank the Deputy for her question. As she points out, the capital expenditure levels for 2021, as originally set out in the Revised Estimates Volume of December 2019, amounted to €9.1 billion. This figure, which was set out in advance of the Covid-19 pandemic, was almost €1 billion, or 12%, higher than the corresponding 2020 allocation.
As part of the July stimulus, the Government decided that rather than scaling back on planned capital investment in 2021 in response to budgetary pressures elsewhere, we would commit to preserving and maintaining this unprecedented level of capital investment. It is a commitment I will carry through fully in budget 2021. Of course, the precise configuration and prioritisation of the overall increased 2021 capital allocation of €9.1 billion, including the remaining unallocated reserve and any potential for enhancement to those allocations, will be specified further and more comprehensively in the context of budget 2021.
The national development plan, NDP, sets out five-year expenditure allocations by Department for the period 2018 to 2022. These multi-annual allocations are devised to give Departments a degree of certainty for future planning. In direct response to Covid-19, however, the Government made necessary and large-scale revisions to capital allocations for 2020. The capital expenditure allocations for 2020 were increased by in the region of an additional €1.5 billion, bringing total capital investment for 2020 to above €9.7 billion. This is the highest ever investment in capital projects and programmes in the history of the State.
In line with programme for Government commitments and in my capacity as Minister for Public Expenditure and Reform, I am bringing proposals to the Government regarding the launch of a structured, in-depth review of the NDP in order to advance the priorities identified in the programme for Government, including climate change, housing policy, transport policy, implementation of Sláintecare and balanced regional development, aligned with the associated multi-annual resourcing requirements. The revised NDP, to be published next year, will assess the balance of resourcing between sectors in light of the programme for Government and will consider if there is a need for any strategic changes in allocations beyond 2021.
