International Climate Action

Debate between Lord Duncan of Springbank and Lord Birt

Thursday 26th September 2019 Lords Chamber

[Lord Duncan of Springbank]

I am probably going to frighten my officials when I say that I suspect the answer is no. I think we need to be investing significantly in the technologies that are available. We also need to seriously consider how we move those technologies, given the way in which they are already used within the UK and the EU, to countries where they can do the maximum good. Carbon capture utilisation and storage offers us opportunities, if we use these methodologies wisely and carefully, in removing carbon. We have to remember that there are chemical processes—for example, the production of ammonia—where we simply cannot do without carbon dioxide because it is part of the natural chemical equation. We need to find ways of removing the carbon as best we can through those technologies.

Storage must be at the heart of where we go now. The progress that we make on wind will simply be blown away unless we can capture it and hold it in some form of storage. The pump hydro stations that exist in Scotland and Wales are a very useful example of that, and Norway has a significant number of those, but we need to think of other technologies as well, such as battery technologies, to retain that electricity.

We need to be global leaders in this area. In fact, the EU has to be a global leader in this area too, and we should be collaborating strongly through the Horizon programmes to ensure that we remain committed to technologies and ensure that they are available, not just here in Europe but wherever they can do good.

[Lord Birt (CB)]

I applaud the Minister’s high productivity today—he must have been up all night—as well as his manner. Would that there were more like him.

I strongly approve, as everyone who has spoken plainly does, of the Government embracing the net zero target. However, as the Minister has made clear in his answers already, finding the pathway to achieving that target is an enormous task. As he says, on the other side of Brexit it will be arguably the single biggest challenge that this country has to face. For instance, the previous Chancellor identified the scale of GDP that will have to be devoted to ensuring that our transport system, the heating of our homes and buildings, and our electricity generation is de-carbonised. It is an enormous challenge. The Government have declared their target. When are they going to set out the framework for achieving it—the multiple pathways which the Minister has referred to—and meeting that ultimate challenge?

[Lord Duncan of Springbank]

The noble Lord is absolutely right: setting a 2050 net zero target is important as a point on the horizon to be reached, but it is the pathways we will take to get there that will be the challenge. He is right again when he reminds us that the Chancellor gave an estimate of how much he thought this might cost this country alone, but it is sometimes more useful to take it down to the level of the individual household. To consider what it will mean, think of a household that has one car and a central heating system using gas, and think of having to move that forward. There are different technologies that we may be able to use to increase the efficiency of the electricity going into the home, but when we begin to talk about the changeover, particularly with vehicles, we are talking about significant individual household investments, and we cannot shy away from that.

One of the greatest dangers we face today is the number of times people conflate the words “electricity” and “energy”. On some days you will hear that we are approaching close to getting 100% of our electricity from renewable sources, but if you put the word “energy” into that, you are absolutely wrong, because our transport system and the way we heat our homes are primarily hydrocarbon based. We are not one small step away, and unless the general public appreciate that, they will wonder why we are not going faster.

The challenge we need to map out is the one that the noble Lord rightly pointed out. Our plan as we approach the glide path to COP26 in Glasgow must be to set out very clearly not only the routes we are seeking to explore, because some need exploration, but the targets and milestones by which we can measure our progress. We must also set out how we can look at that as a means to encourage others to follow in our slipstream. In truth, as I said, if we achieve this ourselves, we will have done little at a global level: we must have others come alongside. Once we have seen the framework, we should probably gather together once again to explore the details of how it might work in reality and to look at the costs, because it will not be without costs, and commitments required from individual households to change their behaviour.
