Deep Sea Mining Bill

Debate between Sheryll Murray and Barry Gardiner

Friday 6th September 2013 Commons Chamber

[Sheryll Murray]

Deep-sea mining takes place at great depth in specific areas of the ocean. I do not think that the warps, bridles and trawl doors on my late husband’s boat were long enough to trawl the sea bed. We should not excavate in a non-environmentally friendly way, and I will come on to discuss that. This is one of the reasons why the UK needs to amend the 1981 Act, so that we can impose stringent and clear environmental conditions. The UK takes part in the council meetings, which are considering—this was started at the last meeting in July—what conditions should be applied to the exploitation. These are very early days—we are talking about exploration at the moment and not exploitation, which is still some way off—but the UK should be a leader in that sphere.

I am most heartened by the hon. Lady’s response to the hon. Member for Dover (Charlie Elphicke) that one of the reasons why it is important to legislate and ensure that licences come through the UK state system is that we would then be able to apply improved environmental measures. However, I do not see any mention in the Bill of a requirement on the Secretary of State to do that. I would be grateful if the hon. Lady could point out to me any such requirement.

[Sheryll Murray]

I welcome the hon. Gentleman’s intervention. I think the whole House will know how interested he is in the global maritime environment. However, he may be unaware—I am sure my hon. Friend the Minister will expand on this—that a lot of the environmental requirements will be covered in the wording of the contract with the International Seabed Authority, so we do not to include that in legislation.

[Barry Gardiner (Brent North) (Lab)]

I am delighted to speak in this debate, which is important not simply because of the economic interests that the hon. Member for South East Cornwall (Sheryll Murray) has outlined; she spoke of a potentially accessible resource that could be worth something to the tune of £40 billion. As she appreciates, it is also important because of the natural environmental resource that could be at risk from both the exploration, and ultimately the exploitation, of those resources.

I was grateful for the clarification made by the hon. Member for Bury North (Mr Nuttall) on clause 5 of the 1981 Act, which I have highlighted in my copy. When he quoted the clause, however, he left out one salient phrase:

“so far as reasonably practicable”.

Let me quote the clause in full:

“In determining whether to grant an exploration or exploitation licence the Secretary of State shall have regard to the need to protect (so far as reasonably practicable) marine creatures, plants and other organisms and their habitat from any harmful effects which might result from any activities to be authorised by the licence; and the Secretary of State shall consider any representations made to him concerning such effects.”

In its time, that was an eminently good and sensible environmental protection to introduce, but 32 years later, environmental law has superseded it. It is no longer the significant protection that it may have been regarded as when it was introduced in 1981.

In particular, we need to pay attention to principle 15 of the Rio declaration—the precautionary approach—in all such environmental matters. Principle 15 states simply that, if there are indications of likely but uncertain significant adverse environmental impacts, an activity should not be authorised to proceed. The principle switches the burden of proof. Of course, in overall terms, deep-sea ecosystem processes, connectivity and the importance of deep-sea ecosystem services are poorly understood by contemporary science.

The hon. Member for South East Cornwall described some processes, and mentioned scooping and vacuuming, but she will also know of the process of crushing when mining for these nodules. More than most hon. Members, she will be aware of the deep-sea ocean currents that can take sediment produced from such operations and disperse it over wide areas. As some of the minerals being explored are so toxic, it is difficult to understand with modern science just what the effect of their dispersal by those deep-sea ocean currents could be.

[Sheryll Murray]

Is the hon. Gentleman aware that the polymetallic nodules are golf ball-size spheres that occur in ocean bed sediments? I bow to his expertise, but my knowledge of the sea bed suggests that trying to crush a polymetallic would simply bury it further into the sediment. We need the Bill so that the UK can ensure that the environment is cared for and so that the activities are undertaken in the most environmentally friendly way. If he is concerned about the hoovering and harvesting of the nodules, he should support my Bill.

[Barry Gardiner]

Let me give the hon. Lady the assurance that I am sure the Bill will pass on Second Reading. I have no desire to stuff it and am not foolish enough to attempt to do so. However, I would like to obtain from her and the Minister another assurance: that the environmental protection, which is currently only in the 1981 Act, will be strengthened when the Bill goes into Committee. The burden of proof in the precautionary principle is reversed in the Act, which states:

“In determining whether to grant an exploration or exploitation licence the Secretary of State shall have regard to the need to protect”.

I want to change the focus, so that instead of the Secretary of State having regard to the need to protect, no licence is granted unless full environmental impact assessments have been undertaken.
