Electrifying UK railways and climate change
I use the case of the electrification of the railways as an example of climate mitigation. Diesel trains are hugely polluting, particularly in the context of carbon dioxide; electric trains much less so. Seemingly a switch from car to diesel train can cut an individual’s carbon emissions by 70 per cent and a whopping 90 per cent if the train is electric.
The electrification of the network has always been rather piecemeal. The East Coast Mainline was electrified in the 80s, but missed out key towns and cities such as my home town, Hull. Diesel trains still run under the wires from London to the city. More startling, but not surprising is the account given by Aneurin Redman-White, a railway design consultant, of the mess that is Brunel’s original railway Paddington to Bristol/Cardiff and Penzance. The Penzance bit was abandoned by Chris Grayling, the former secretary of state for transport, even though it had been used as a reason for price increases! It’s like watching a mini-series on TV but not watching the concluding episode. But, actually, it is not like that at all.
Unfortunately, the current British Government, like many before it, believes that private mobility – cars – are still the future and perennially electorally popular. Notwithstanding the fact that governments should always lead rather than follow, especially on global challenges such as climate change, the decision not to electrify the railways on cost grounds, whilst continuing to build roads, is short sighted and wrong.

There is another option, instead of electrifying the infrastructure – at least for short or middle distance routes – battery trains are becoming an option. Great Western Railway in England has now publicly trialled such a train (right – with Mark Hopwood, MD). This train is giving 86 miles (138km) per charge. And charging takes – wait for it – 31/2 minutes.
There are hybrid electric trains, too. Hitachi Rail runs 20 so-called tribrid trains across Italy. The battery is charged when the train decelerates by braking or when it is collecting charge from an overhead wire. There is only 10 miles manageable per full battery, however.
Network Rail, the owner of the UK infrastructure such as track and signalling, has a net zero carbon target for 2050. To meet that target about 500kms of new electrified railway is needed each year. At the moment, a mere 38 per cent of the UK rail network is electrified. The German railways, by contrast, are reported to be 90 per cent electric operation (slightly different terms, I appreciate, but even then, a significant difference).
The argument that the UK railways contribute only about 2 per cent of greenhouse gases across all sectors is a classic response. What is 2 per cent? For that amount, it is not cost-effective. Investment in public infrastructure can be cost-effective, especially if we consider wider social returns in terms of employment and mobility more generally (just look at what CrossRail/Elizabeth Line has done for the Capital). Moreover, maintaining the capability to design, build and maintain infrastructure is, arguably, a requirement of a post-carbon (aka civilised) world.
Banksy’s artworks
Gio Iozzi asks, why does it take an artist to expose the assault on our urban trees? This in light of Banksy’s latest addition to his portfolio recently found in Finsbury Park, London. It is an interesting work, and slightly different from his usual work, as it requires a significant prop. A tree. The tree is special because it has been “pollarded” – severely pruned in normal parlance. It has been pollarded because, according to the Council (the owners of the land on which the tree stands) it was diseased. It is a cherry tree, and they do not, it seems, respond well to radical pruning. There is also a question of whether diseased trees need to be pruned or felled. Many of us are a little diseased, but we do not lob off all of our limbs to deal with it. Or at least not as the first option.
It seems that Banksy, whoever he is, saw the opportunity to provide this sad tree with leaves by painting them – or spray painting them – onto an adjacent side wall. Viewed from one angle, the tree looks healthy and with full plumage. And like all Banksy artwork, there’s a message.
Art is there for the receiver to interpret, even if the artist provides the artwork with their own meaning. So we take liberties – rightly – with interpretations. So let us interpret this widely. This is a dual statement about the state of our urban trees and about climate change. Urban trees are under threat, just at a the time when we need them most. Our cities are getting hotter. Trees provide shade, for sure. But they also cool the air. Even diseased ones. So much urban landscape is devoid of trees. Devoid of ways of cooling and, increasingly, draining.
More broadly the onslaught against the planet’s forest ecosystems is relentless. The cutting and burning of the Amazon has slowed, but not stopped. Forests elsewhere in Indonesia and Africa are also in retreat. In Brazil particularly to provide land and feed for cattle. So not only do we lose carbon-capturing trees, we also increase our emissions through bovines, notorious methane producers. All because we want to eat large quantities of beef.
In response to Iozzi’s opening question about artists, I respond simply by saying, it is what artists do. It is why they are an essential part of the democratic process. Throughout history artists (not all, for sure) have made statements about society, power and morals. Degenerate art in Nazi Germany was degenerate for a reason. Artists have been subtle sometimes in their representations. Messages that eluded the censors because they were unable adequately to understand what they were actually looking at. Even Picasso, not known for his political statements, produced his masterpiece, Guernica, to say something to the perpetrators of the destruction of the Spanish town in 1937. Famously when asked by a Nazi Officer at his Paris studio whether he had “done” this painting, his reply was “no, you did this”.
To add value to the picture and to the metaphor, Islington Council put a protective fence around the work, but within 48 hours it had been defaced. I am pretty sure that Banksky was smiling. I rest my case.

The Garrick Club
The Guardian’s recent exposé on the Garrick Club in London is troubling. It took a data breach for us to know who the club’s members are.
Not only is this a “gentlemen’s” club, it is also an elite club where state/government policies are discussed and made. As a man I do not have the resources to join and even if I did, I think it is unlikely that existing members would nominate me. I could at least try; but if I was female, it would be harder despite David Pannick KC’s best efforts to justify its existence. There is, argues Pannick, nothing in the language that bars women – even the word “gentleman” seemingly has a defence. Here is Pannick quoted in the Guardian article: “[t]he term ‘gentlemanly’ is plainly being used here in the sense of the meaning ‘[o]f a pastime, behaviour or thing’ that is ‘of high quality; excellent’”. I’m not about to buy that. It is not surprising that lawyers can offer such a defence as we discover that a large tranche of senior [read influential] figures in the profession are members. Many environmental campaigners, for example, have found themselves judged by them. And that raises bigger questions about the profession itself.
