Mariana Dam Disaster

John McDonnell Excerpts

Thursday 22nd June 2023 Westminster Hall

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

I thank the Backbench Business Committee, right hon. and hon. Members from across the House who have been involved, and my friend, the hon. Member for Strangford (Jim Shannon), for securing this emotive and hard-hitting debate. It is about how British companies conduct themselves around the world and whether they implement the highest safety standards, which we rightly expect of them. It is also about how we hold companies headquartered in London or elsewhere in the UK to account when they do not live up to the standards that they claim to uphold.

The House’s sub judice rule—as you rightly pointed out, Mrs Latham—prevents me from commenting on any ongoing court action relating to the hundreds of thousands of claimants seeking compensation for damage caused by this horrific incident. However, as the hon. Member stated, the Mariana dam disaster has been called

“the worst environmental disaster in Brazil’s history.”

The disaster severely impacted indigenous communities including the Krenak people by irreparably damaging the river source and the community’s lifeblood, the Rio Doce. It is important that we recognise the victims and their grieving families, with 19 lives lost because of the disaster. For the people of Brazil and other fair-minded, good people around the world, such disasters must not be forgotten, or we are doomed to repeat the mistakes of the past.

The people of Brazil believe that the disaster could and should have been avoided. Indeed, the 2017 report “The River is Dead” by the London Mining Network states:

“Since the beginning of the operation, in 2008, the Fundão Dam had presented several anomalies related to drainage defects, upwelling, mud and water management errors and saturation of sandy material. In some cases, emergency measures had been required.”

However, the project continued, and production was kept at high levels until the disaster.

A recent report published by the Local Authority Pension Fund Forum, after some of its members visited Brazil, found:

“Nearly seven years after the dam collapse, the end of these reparations and compensation is nowhere in sight. Consequently, affected community members have suffered for over seven years, and the companies and investors continue to accrue costs associated with the delayed provision of reparations and compensation”.

Companies running large operations worldwide cannot be allowed to hide behind their subsidiaries when things go wrong or when there is an ecological and environmental disaster. The UK has an important global role. It can and should lead the way by exploring ways to introduce stronger accountability mechanisms for UK corporations operationally, both domestically and internationally, to help to protect against human rights abuses and protect our fragile environment.

[John McDonnell (Hayes and Harlington) (Lab)]

I apologise to my hon. Friend and to you, Mrs Latham. It is one of those days when there is a lot going on in the other Chamber that we take an interest in, so I will need to go, but I want to raise one point first.

I completely understand why the Chair is twitchy about sub judice issues, but the whole point of having this debate is so that maybe some good can arise from this tragedy. There is potential for our Government to lead on legislative reforms, which can then be developed internationally to ensure the accountability of companies, prevention of human rights abuses and environmental protections. It is about directors’ responsibilities as well. There is an agenda that the Government could seize to turn this tragedy into something beneficial globally.
