We expect the that costs associated with the remediation in the longer term to be significant. Depending on the scale, it is unlikely that we can reasonably absorb the cost of the works required within existing budgets, especially given the £100 million general capital reduction we have just seen. That is why I've written to the Chief Secretary to the Treasury, seeking additional financial support outside of the normal Barnett process. I welcome the indication that additional funding for Wales will be made available by the UK Government, but we wait to see the full details of what support will be provided in practice. I would expect to make further allocations in support of the flood recovery in the first supplementary budget.

The storms we have seen in recent weeks demonstrate the significant consequences of climate change. Throughout the scrutiny of the draft budget, Members have expressed concern about the impact of climate change. Be in no doubt, taking on the climate emergency is a priority across the Welsh Government. In May last year, this Senedd was the first Parliament in the world to declare a climate emergency. We subsequently formally adopted the advice of our statutory adviser on climate change, the UK Committee on Climate Change, committing to reducing emissions of greenhouse gases in Wales by 95 per cent over the next 30 years.

This is the first budget since our declaration of a climate emergency. It provides for a new package of more than £140 million of capital funding to support our ambitions for decarbonisation and to protect our wonderful environment. This includes investment in active travel and an electric bus fleet; new ways of building houses; enhancing our most ecologically important sites; and the development of a national forest, to extend the full length of our country. This package of investment is an important next step on our journey to a greener Wales. 

We recognised in the draft budget that the greatest physical risk to our communities from climate change is through the increasingly intense storms, flooding and coastal erosion that we're already witnessing. In this budget, we're committing £64 million in 2020-21 to defend our communities from the most severe and immediate impacts of climate change, and we will keep funding under review and will make more funding available if needed. 

It remains unclear at this stage what the UK budget on 11 March will deliver for Wales. Should we not see any reduction in revenue funding from the UK budget, I will look to make a small number of further allocations in 2020-21 in the first supplementary budget. Whilst constrained by limited resources, we are committed to investing in those areas where the evidence shows that we can have the greatest impact. During scrutiny, Members expressed concern about funding for both the housing support grant and homelessness. Housing is one of our eight cross-cutting priority areas. In this budget, we allocated an additional £175 million to support our housing needs. We want everyone to live in a home that meets their needs and supports a healthy, successful and prosperous life. That is why I want to signal now that I will make additional funding available for both these areas next year, if I am in a position to do so after the UK budget. It is also why we're progressing our plans for the new land division within the Welsh Government, which will promote joint working between public sector bodies to unlock the potential of our public land for housing developments. 

Another important issue raised duiring scruitny was funding for buses. Bus services across Wales provide important access to education, training, work and healthcare and allow people to simply enjoy a day out. They're a vital link between our communities and an important tool in supporting a vibrant economy. This is particularly true in our rural communities and for the people who depend on these services the most. As I said at Finance Committee, we will keep this under review and I will consider making additional allocations in this area in light of our final settlement for 2020-21. 

Recognising that the decarbonisation of road transport is essential to delivering our net-zero target, we're taking action to make it easier for people to make fewer journeys by car and use alternative forms of transport. As well as investing in new forms of transport, however, we also need to meet our statutory obligations to maintain our existing road assets, to allow people and goods to move safely, prevent the risk of accidents, improve connectivity and access to education, skills, training and employment. The maintenance budget of more than £150 million includes an additional £15 million in 2020-21. However, the UK Government's decade of austerity has had a direct impact on the maintenance of the UK's road network. In Wales, road traffic congestion has been exacerbated by the UK Government's £1 billion underfunding of transport infrastructure, and the failure to electrify the main lines in north and south Wales, leading to increased traffic on our trunk roads. Therefore, I see the maintenance of our road network as a further priority for additional funding, particularly for the reasons of safety I've outlined. 

So, to conclude, this final budget delivers on the promises we have made to the people of Wales. It takes our investment in the Welsh NHS to £37 billion over this Assembly term, and provides new investment to help protect the future of our planet. Despite the challenges that we have faced as a result of the UK Government's unpredictability and chaos, I am proud that we have remained firm in our plans to deliver on our promises to the people of Wales and provide financial certainty. And I commend the final budget to the Senedd.
