My Lords, the purpose of this order, which was laid before the House on 4 November 2021, is to give the Government the powers to implement the International Convention for the Control and Management of Ships’ Ballast Water and Sediments—or “the convention”, as I shall now refer to it—into UK law. The order relies on powers in Section 128(1)(e) of the Merchant Shipping Act 1995, which I shall refer to as “the 1995 Act”. This order, if approved, will contain powers to make a new statutory instrument under the negative resolution procedure this year.
As noble Lords will be aware, shipping is essential to our global economy. In fact, it is estimated that it transports around 90% of the world’s commodities. In doing so, it transfers 3 billion to 5 billion tonnes of ballast water every year. This makes ballast water one of the most effective vectors for the transport of species around the world. For example, noble Lords may well have heard of the Chinese mitten crab, which is native to eastern Asia but was first discovered in the Thames estuary in 1935. It is one of the most destructive examples of invasive non-native species, as it preys on native populations, burrows extensively, causing damage to flood defences and riverbanks, and causes commercial losses in fisheries.
I should like to give some background about what the Government have done regarding the convention and outline the Government’s reasons for wanting to ratify it. In doing so, I remind noble Lords that our purpose today is to discuss the use of this draft order as a mechanism to provide the powers for the implementation of the convention, rather than to discuss the detail and implementation of the convention itself, which remains in progress.
The convention was adopted at a conference convened by the International Maritime Organization, or IMO, in 2004, and it entered into force internationally on 8 September 2017. It aims to prevent, minimise and ultimately eliminate the transfer of invasive non-native species through the control and management of ships’ ballast water and sediments. It does this by prohibiting the discharge of ballast water and sediments unless they have been managed in accordance with the convention requirements. The United Kingdom has not yet ratified the convention.
Noble Lords will note that the convention entered into force internationally four years ago, and it is quite reasonable to ask why we are only now seeking powers to implement the convention. The reason is that the UK had concerns regarding the availability of the equipment required for the sampling and analysis aspects of the convention. Delaying the UK’s ratification of the convention has allowed for these concerns to be addressed.
Subsequently, the UK rescheduled ratification and implementation of the convention to wait for amendments to the convention to enter into force, thereby ensuring that the UK implementing legislation, which is coming down the track, reflects the most up-to-date version of the convention. The Government made a public commitment to accede to the convention in 2020. This was again rescheduled to avoid placing extra burdens on the industry during the Covid-19 pandemic. The Government consider that the implementation of the convention into UK law is an important step to ensure that UK waters are protected.
