Tunnel imaginative and prescient

The consultants, Component Power, give attention to technical and engineering options about which many researchers are sceptical – however even they admit that “reaching web zero early can’t be achieved by expertise alone”.

Requested by the mayor to point out how London’s transport might be decarbonised extra quickly than beforehand deliberate, the consultants suggest large-scale “behaviour change”: in an “accelerated inexperienced” situation, a 27 % discount in visitors measured by automobile kilometres pushed per 12 months – or, in a extra bold “no constraints” situation, a 40 % discount.

Even these swingeing cuts in visitors quantity wouldn’t be sufficient to satisfy London’s local weather targets, in response to Component Power. A big expertise shift can be wanted, too: within the “accelerated inexperienced” situation, 46 % of London’s vehicles can be electrical, and 10 % hybrid, in eight years’ time.


Different transport researchers are sceptical concerning the decarbonisation impact of electrical autos, and advise nonetheless better emphasis on lowering visitors. 

Which method will London go? The town could make an enormous collective effort to scale back street visitors volumes. Or it will probably pour assets into the Silvertown tunnel, a street enlargement challenge. To faux it will probably do each is doublethink.

In a response to the Component Power proposals, the mayor proposes to introduce London-wide street person charging “by the mid-late 2020s”, elevating one other query mark over plans to finance the tunnel challenge with tolls. Would tunnel tolls be launched on high of city-wide street fees? It strains credibility.

In April final 12 months, 72 local weather scientists, transport researchers and different consultants warned that the “foolhardy” tunnel challenge would “undermine the UK’s efforts to handle local weather change”. Metropolis Corridor responded by supercharging its doublethink.

The mayor’s workplace by no means answered the local weather researchers’ plea. As a substitute, when MPs and neighborhood activists wrote their very own protest letters, Heidi Alexander, former deputy mayor of transport, replied with what I contemplate to be deceptive data and inaccuracies.


In a kind letter despatched to those that questioned the tunnel challenge, Alexander – who resigned on the finish of final 12 months, and now hopes to be Labour’s parliamentary candidate for south Swindon – said:

* That the London local weather targets – then much less bold than the brand new targets set this 12 months – had been “zero carbon targets”. In truth they supplied for London to pour 18 MtCO2e/12 months into the environment in 2030, and 5 MtCO2e/12 months in 2050. These numbers aren’t zeroes!

* That the targets had been based mostly on “modelling of carbon emissions” that “takes into consideration deliberate developments such because the Silvertown tunnel”.

They weren’t. They had been underpinned by assessments from Jacobs, the engineering agency, which included public transport tasks corresponding to Crossrail 2 and extensions of the Docklands Mild Railway and Bakerloo strains – all subsequently scrapped – in addition to the tunnel.

The one modelling of the tunnel’s greenhouse gasoline influence, published by TfL in 2016, indicated that (i) the tunnel would add 23,000 tCO2e/12 months, and (ii) within the mid-2030s, London’s street community would produce greater than 5 MtCO2e/12 months of greenhouse gasoline emissions, greater than twice the extent allowed for by the local weather targets.

* That London’s carbon discount trajectory, linked to its local weather targets, has been “independently assessed” by C40 Cities, the worldwide mayors’ organisation.

In truth C40 employed Arup, the multinational engineering agency, to  examine London’s carbon trajectories – on which Arup labored as consultants – with C40’s personal Deadline 2020 trajectories which had been in flip drafted by a group led by Arup staff.  

In actuality, there was at all times a large hole between eventualities by which the Silvertown tunnel is constructed, and eventualities by which London meets its local weather targets. By adopting new targets in January, the mayor has made this hole wider.


Metropolis Corridor’s doublethink has additionally been utilized to move coverage. When TfL managers first modelled the Silvertown tunnel’s influence on visitors volumes, they informed the pc to imagine, upfront, that there can be no further journeys throughout the Thames.

This breached the important thing principle, verified by a long time of transport analysis and encoded in experiences to the UK authorities in 1994, 1998 and 2018, that extra roads produce extra visitors.

TfL managers have since admitted that the Silvertown tunnel might make visitors volumes rise by 15-30 %, in flyers distributed to native residents. However, they declare, the proposed toll on the tunnel – and on the Blackwall tunnel just a few metres to the west – would clear up the issue.

Earlier expertise, for instance on the Dartford crossing and the M6 toll street, reveals that tolls shouldn’t have this impact: visitors volumes might rise despite them.

And authorized recommendation, each to the borough of Greenwich and individually the Cease the Silvertown Tunnel Coalition, confirms {that a} future mayor might take away tolls, anyway.  


That was the topic of the tweet that Newham mayor Fiaz shared, and to which Sadiq Khan objected so strongly.

The tweet additionally identified that TfL is unsuitable to name the Silvertown tunnel London’s “first new river crossing in over 50 years”. There’s the Millennium Bridge, the Jubilee line, the Docklands Mild Railway, the Golden Jubilee bridges and Crossrail.

Metropolis Corridor’s doublethink on local weather and transport goes hand in hand with doublethink about native democracy.

The mayor’s employees have constantly stonewalled our marketing campaign, and refused all of our repeated invites to debate the tunnel in public.


However even they’ve been outdone by the previous management of Greenwich council, which for 2 years claimed, bizarrely, that there was “no authorized avenue” by which they might oppose the tunnel.

Query: might you ship a letter or e mail to Sadiq Khan, asking him to pause and overview this ruinous challenge? Reply: there’s “no authorized avenue”. Critically. In a rustic with affordable ranges of free speech, within the 2020s.

In February, when councillors who oppose the tunnel pushed the difficulty on to the agenda of the borough’s Overview and Scrutiny Committee, authorized officers advised that physique, wrongly, that it was inhibited from taking motion by the Growth Consent Order issued to approve the challenge in 2018.

The authorized precept that councils can categorical an opinion on any difficulty impacting native residents was ignored.

The council management’s efforts to silence our protests went into overdrive. The previous native mayor, Denise Hyland, rejected our repeated requests for a deputation to handle the council, and refused to permit public questions concerning the tunnel challenge, each on “authorized” grounds.


On 24 February, we lobbied a council assembly; Hyland, former council chief Danny Thorpe and others caught stubbornly to the “authorized” doublethink.

I recollect it effectively, as a result of, on that day, Russia had invaded Ukraine. Dozens of native authorities officers in that nation had risked arrest by signing an attraction to the Kremlin to cease – whereas their snug counterparts in Greenwich used doublethink to elucidate why they might not act.

In the long run, the voters in Greenwich compelled a change. The ruling Labour group, confronted with shedding seats to the Greens within the Could council elections, abruptly reversed its place, found that “authorized avenues” existed, and known as for the tunnel challenge to be paused and reviewed. However injury to native democracy had nonetheless been finished.

The native is world. If the Silvertown tunnel challenge goes forward, it won’t solely exacerbate air pollution issues in Greenwich and Newham that can disproportionately hit Londoners of color and low-income households; it’s going to additionally stop London from assembly its local weather targets and making an efficient contribution to tackling local weather change.

This issues past London. Sadiq Khan wields extra government energy than another Labour politician; his promotion of local weather doublethink reveals us what a future Labour authorities would do.


This doublethink won’t idiot the thousands and thousands of victims of climate-change-related heatwaves and flooding throughout the worldwide south. But it surely makes all of our efforts to take care of these issues tougher. It must be challenged, uncovered and defeated.

The time period “doublethink” was coined by George Orwell in his novel 1984, written in 1949 and set in a dystopian world dominated by “the Celebration”.

“Winston [the novel’s main protagonist] sank his arms to his sides and slowly refilled his lungs with air. His thoughts slid away into the labrynthine world of doublethink”, Orwell wrote.

“To know and to not know, to take heed to full truthfulness whereas telling fastidiously constructed lies, to carry concurrently two opinions which cancelled out, understanding them to be contradictory and believing in each of them, to make use of logic in opposition to logic, to repudiate morality whereas laying declare to it, to consider that democracy was not possible and that the Celebration was the guardian of democracy, to overlook no matter it was essential to overlook, then to attract it again into reminiscence once more in the mean time when it was wanted, after which promptly to overlook it once more, and above all, to use the identical course of to the method itself – that was the final word subtlety: consciously to induce unconsciousness, after which, as soon as once more, to develop into unconscious of the act of hypnosis you had simply carried out. Even to grasp the phrase – doublethink – concerned using doublethink.”

Proper of Reply

A spokesperson for the mayor of London informed The Ecologist: “The Silvertown Tunnel will rework the best way folks can journey in part of London that at present has few choices for crossing the Thames. 

“Along with offering new, zero-emission, cross-river bus companies for an space in want of them, the tunnel will massively scale back the continual automobile congestion and air air pollution issues at present related to the insufficient, Victorian-era Blackwall Tunnel.

“Each the Blackwall tunnel and new Silvertown tunnel will likely be topic to a person cost and, when mixed with the Mayor’s general coverage of lowering automobile use throughout Larger London in favour of lively and public transport choices, will assist scale back congestion with out growing the amount of visitors crossing the river.”
