Yes, thank you, Huw. I'm familiar with Lord Deben, obviously. We have had a lot of interaction with him and with the committee. Yes, so, the final statement that we issued was focused on the first carbon budget only, and although the Environment (Wales) Act was introduced in 2016, the first plan was only published in 2019 because we were out of synch for that first legislative cycle. So, it is important for the committee to get the timeline right. So, the first plan was in place for less than two years of the first carbon budget. So, it's important to take that into account. Also, most Welsh emissions occur in non-devolved policy areas. So, we rely on UK Government action to deliver emissions reductions in several key areas, which I'm sure the committee will come on to later on. So, we need absolutely to work in harmony with the UK Government so that they continue to deliver policies that reduce emissions here in Wales.
The final statement that we put out explains the monitoring and reporting system. I will say, Huw and Chair, it's incredibly technical. So, I usually like to get across all of this myself, but I'm going to rely on my officials for some of the technical expertise here, because you really do need to be a technical expert in some of this stuff. So, depending on the level the committee wants to go into, officials will fill in some of that. I'm sure you know that the final statement is split into sectors. So, power, the transport industry and waste are the main contributors to Wales's success over carbon budget 1. So, the final statement goes into our policies and which achieved the desired direction of travel, and they provide a qualitative update, but we're continuing to improve the monitoring and reporting system as we go forward.
There have been a number of areas where we have made progress: implementing energy consenting powers arising from the Wales Act 2017, the 'Planning Policy Wales' documents, and the Welsh national marine plan are all now in place. In January 2021, alongside other Governments of the UK, we implemented the UK emissions trading scheme, and, in terms of existing homes, the Warm Homes scheme has seen increases in the funding provided and its reach. We also have—and I know the committee has discussed this with me a lot of times—the innovative housing programme, targeted at new homes, which has provided grants totalling over £180 million, or just over 2,000 homes, between 2017 and 2020. We've also got support in the public sector for schemes like the Welsh Government energy service, which had £50-something million for energy efficiency public sector projects between 2018 and 2020. And the big piece for Wales, of course, is reducing the amount of waste sent to landfill, encouraging the adoption of what we call the blueprint waste collection systems, which is the Welsh Government's recommended way to collect household waste in Wales. We've had some really good successes, even just very recently, as authorities finally swap across to blueprint, having been able to demonstrate its efficacy. And we've also, of course, increased the number of social homes compliant with the Welsh housing quality standard.
Going to Lord Deben's particular point, the 2020 target and carbon budget 1 were placed in regulation in 2018 and they were entirely based on the Climate Change Committee's advice. I guess it's a self-criticism in a way. We agree they were too low for net zero, because we only passed net zero into law in 2021. It wasn't possible to amend the 2020 target or carbon budget 1 to align with net zero, because originally the climate committee's advice to us was that we would not get to net zero. We set the 2020 target in 2018, so we were on the pathway to the original 80 per cent reduction by 2050. That followed their recommendations at the time. Then, obviously, we received advice on the net-zero target in December 2020.
For carbon budget 2, we followed the CCC's latest recommendations to make it more challenging. We accept the view that Wales will need to outperform the revised CB2 to be on track for CB3 and beyond. Just to put that the other way around, we know we will make carbon budget 2, but we need an awful lot to get to carbon budget 3. We need to well exceed the targets to be on track for carbon budget 3. The latest advice in December 2020 recommended we increase carbon budget 2 from a 33 per cent average reduction to 37 per cent, because the Aberthaw power station had closed earlier than had been allowed for in its original advice. They also advised us that the economic uncertainty arising from the COVID pandemic, and the significant influence of UK Government action on Wales's short-term emissions, meant they did not recommend setting a higher carbon budget 2 in law. But they did recommend that we outperform the 37 per cent statutory target, to get on track for carbon budget 3, which is 57 per cent, and the 2030 target of 63 per cent. Again, to put that the other way around, Huw, we'll need to do twice as much in the next 10 years as we did in the last 20, so it's quite scary stuff.
I think, broadly, we agree with Lord Deben, but we were following their advice. I think this demonstrates that the world is changing in this regard. We are getting a much better grip of what needs to actually happen and some of the really quite radical changes that will have to be made to get anywhere near these targets. And again, Chair, and Huw, just to say, if you want more technical detail there, I've got various officials on the call who are much more expert than me in the technical details of it.
