The ‘T-charge’ shows how London is leading the way in tackling congestion and pollution

With the government’s March 2018 deadline for places to tackle roadside nitrogen dioxide fast-approaching, there is much that UK cities can learn from London’s steps to address pollution – in particular, the recent introduction of the new ‘Toxicity Charge’ (or T charge) on 23 October.

The new charge is part of a long line of measures put in place by the capital to address two of the biggest costs of its economic success: congestion and air pollution. London has some of the highest levels of pollution in the UK, which contribute towards shortening the lives of Londoners by between nine and sixteen months, and kill thousands of people every year. Over the past 15 years, the city has taken a number of steps to tackle these problems:

  • In 2003, it introduced the London congestion charge zone, which remains as one of the largest of its kind in the world. This aims to reduce vehicle usage in central areas of the city, and to raise investment funds for London’s transport system.
  • The low emission zone was introduced in 2008, which exempts low emission vehicles from the congestion charge area – meaning that only vehicles that do not conform to higher emission standards are subject to the charge.
  • London has introduced low emission buses on some routes, and around 5,000 buses are set to be upgraded to meet the latest ultra-low Euro 6 emissions standard, cutting pollution caused by buses by up to 95 per cent.
  • The new T-charge aims to build on these measures by placing an emission surcharge for the most polluting vehicles entering central London, the first such surcharge introduced in a UK city (and to our knowledge, in any city across the world). With the aim of phasing out older Euro 4 vehicles – that is, cars which were registered before 2006 – it will introduce an extra £10 fee on top of the current congestion charge for vehicles that do not meet the minimum exhaust emission standards to enter London’s low emission zone. Transport for London (TfL), which runs the charging scheme, estimates that 40 per cent of drivers subject to the emission surcharge will upgrade their vehicle and 7 per cent will stop travelling into the zone.

The charge will also offer a significant additional source of income for TfL, on top of the £164m in net income generated by the congestion charge in 2016-17. This can be reinvested in other clean air measures, such as improving public transport and walking and cycling infrastructure. And because it’s a ‘bolt-on’ on to the current congestion charge, very little upfront cash is needed to implement it.

Yet the issue of poor air quality isn’t just a problem in London. Twenty-eight other places across the UK, including Leeds, Birmingham and Nottingham, recorded illegal levels of pollution last year, particularly in their most congested roads and city centres. These places are now required to submit their clean air strategy by March 2018, but none as yet have followed London’s lead by introducing measures such as a congestion charge (Durham is the only other place with this kind of scheme).


The capital’s policies therefore offer a way forward for these other cities – both in tackling congestion and pollution, and in generating income which can be invested in more environmentally-friendly modes of transport.

Epidemiologist update: Covid-19 death toll passes 350,000 worldwide

An update from GlobalData Senior Epidemiologist Nanthida Nanthavong:

Globally, the total confirmed cases of Covid-19 have surpassed 5,609,000 with over 350,000 deaths and 2,287,000 recoveries.

The US continues to have the highest number of cases, followed by Brazil then Russia. Incidence rates in Brazil are also second to the US, but may surpass the US if the current incidence trend continues in Brazil. Russia has reported a steady number of new daily cases for the past week. The Moscow region accounts for the majority of cases in Russia.

Daily incidence rates in India have continued to increase as the country reported four of its highest daily incidence totals over the last few days.

South Africa has the highest daily incidence and highest number of cumulative cases in Africa. South Africa has also reported its two highest daily incidence totals over the last few days.
