So, had the noble Baroness, Lady Bennett, got her amendment in first, the noble Lord would have signed it. It is interesting to know that the Liberal Democrats are against any new fields in the North Sea.

What I want to try to get home to those members of the Committee who have not yet taken it on board is that up to now we have pursued a path to net zero which involves reducing demand for fossil fuels by replacing fossil fuels with renewable energy. That is a logical path to pursue. We have not been seeking to achieve it by reducing supply of fossil fuels. As a result, if people choose to produce more fossil fuels than there is demand, as demand falls fossil fuel producers will be left with stranded assets and lose money. It could not happen to a nicer bunch of people, but why should we think that our judgments are better than theirs or worry about them erring and producing too much, investing too much and not getting their money back? That is up to them.

May I pursue the point? When I have made it and made my own case, I look forward to the noble Baroness demolishing it.

We will continue to use gas, albeit in reducing amounts, for decades, probably alongside carbon capture and storage. That is accepted by almost everybody I know. If the UK bans production, which would be an absurd thing to do, given that we do not ban imports of natural gas, we will simply leave others to supply our needs and needs elsewhere in the world. If lots of countries decide to ban new supply, if they succeed in reducing supply faster than we reduce demand, there will be shortages. Prices will shoot up. There will be the same sort of crisis—and huge profits for the oil industries—and we will have done to ourselves what Putin has done to us by reducing supply more rapidly than demand. I want to know why the noble Baroness, Lady Bennett, and the noble Lord, Lord Teverson, want to introduce that sort of risk into the system. Why not just pursue the steady path of reducing demand until it is net zero?

It is interesting that the noble Lord’s analysis bears a great deal of resemblance to that of the fossil fuel non-proliferation treaty proponents, who point out that we have been seeking to reduce demand and say that they explicitly want to reduce supply. I think the noble Lord was making the case that the price will go up if there is not enough supply. Of course, the reverse is true: if there is too much supply, the price will go down. Indeed, we saw this during Covid, with petrol in the United States—gas, as they call it—where people were actually being paid to store and hold it, because you cannot switch these supplies on and off like a tap. Once you build a field, you are going to keep producing that stuff: you cannot suddenly switch it on and off. So, if you have overproduction, you have extremely low prices and those prices, of course, do not reflect the actual cost and the damage being done, either in terms of the climate or all the other damages that the WHO, signing up to this treaty, points out, in terms of the damage done to human health by burning fossil fuels.

I have good news for the noble Baroness, because those issues were covered in Shale Gas Extraction in the UK: A Review of Hydraulic Fracturing, produced by the Royal Society and the Royal Academy of Engineering. We are all constantly urged to follow the science, so let us follow the science in that review. She discussed water, and according to the review:

“Overall water use is important. Estimates indicate that the amount needed to operate a hydraulically fractured shale gas well for a decade may be equivalent to the amount needed to water a golf course for a month”.


That seems something with which we can probably cope. She then discussed the possible results leading to the pollution of aquifers. The review says:

“Concerns have been raised about the risk of fractures propagating from shale formations to reach overlying aquifers. The available evidence indicates that this risk is very low provided that shale gas extraction takes place at depths of many hundreds of metres or several kilometres.”


In the UK’s Bowland shale, it would be kilometres deep. The review continues:

“Geological mechanisms constrain the distances that fractures may propagate vertically. Even if communication with overlying aquifers were possible, suitable pressure conditions would still be necessary for contaminants to flow through fractures.”


When you have a kilometre or more of stone—impermeable rock—bearing down, you could not get a better seal.

Nevertheless, we do not have to worry about scientific analysis and theory, because we have practical experience. Over a million wells have been fracked in North America; not a single one has resulted in a building falling down from tremors or in a single person being poisoned by contaminated aquifers. So we are bound to conclude that lots of people have been spreading the sort of scaremongering that would make anti-vaxxers blush—even Andrew Bridgen would probably blush if he heard some of the stuff that has been put out by the friends of the noble Baroness, Lady Bennett, at their various camps around every conceivable attempt to get fracking going. We should rely on the science and the scientific reports and regulate the industry well, as we have done in the past.

Since the noble Lord addressed me directly on fracking, I ask him if he is aware of the article published in 2020 in Environmental Health Perspectives in the United States which showed that babies with low birth weight are significantly more common in families living close to fracking wells in the US. That demonstrates the practical reality of the outcome of fracking on health.

What is the mechanism by which those babies are born with low health when they are near a well?

The scientists behind that study say that they cannot explain it, that it needs further examination and that there are a number of possible mechanisms.

I have not read the report, but I will read it. I have read similar reports, and almost all rely on the statistical phenomenon that random events are as likely to be bunched together as they are to be evenly spread; I say that as someone who studied statistics. This results in bunches of things; for example, you will get bunches certain cancers somewhere near Windscale, as it used to be called, yet there are bunches elsewhere not near Windscale but people do not worry about them. I very much doubt that there is any scientific basis—and indeed the authors of the article could not think of any scientific basis—as to why we should relate one thing to another in that case. It is the sort of thing that the anti-vaxxers say when they find a little concern. Obviously we should always be concerned about issues such as vaccination or drilling under pressure, but we should not exploit people’s fears to stop something we do not like for other reasons. I hope that my amendment will be adopted and that it will mean that we actually regulate the shale gas industry on exactly the same basis as we do all other industries which can produce similar environmental impacts.
