Low-emission zones (LEZs) have been implemented widely in Europe to tackle air pollution sourced from vehicular emissions. We quantify the effectiveness of the world's largest LEZ—London's LEZ—in reducing its
Low-emission bus zones have helped reduce dangerous toxic air in parts of the United Kingdom capital by 94 percent, according to an annual report from Transport for London, or TFL. Data from its Travel in London study showed the number of Londoners living in areas where the amount of nitrog...

In London, the Ultra-Low Emission Zone (ULEZ) had significant reductions in NO2, not only on the zone implementation but also on the wider LEZ and Greater London Area (Hajmohammadi and Heydecker, 2022; Verbeek and Hincks, 2022). Additionally, Madrid's LEZ implementation achieved reductions ...
markets in more sustainable directions. For example, London is requiring all newly licensed taxis to be zero-emission capable from 2018. This has resulted in five vehicle manufacturers committing to meeting that deadline, which is both in their own commercial interests and good for the environment...
Since the invention of transistors, the flow of electrons has become controllable in solid-state electronics. The flow of energy, however, remains elusive, and energy is readily dissipated to lattice via electron-phonon interactions. Hence, minimizing th
Instead, we measure the energy in the ultra-long-period band and use it as a proxy for the static offset31. Here we use the matched filtered technique32,35 to systematically examine the presence and the stability of such synchronous signals against the VLP catalog during the 2011–2016 Aso ...
The effects of phonon mode depletion induced by the phonon confinement and the corresponding variation in interphonon scattering, which may be important for the thermal conductivities of ultra-thin films but are often neglected in precedent studies, are considered in this study. The in-plane thermal...
This has the advantage of allowing optimisation of the charge transport and emission properties separately. The technique allows ionic dopant (such as the Rhodamine series of dyes widely used in laser dyes, but not currently in electro-luminescent structures) to be incorporated into, for example, ...
Mayor of London Sadiq Khan has proposed a set of measures – including extending the Ultra Low Emission Zone (ULEZ) to cover all of Greater London and a small charge for non-London registered vehicles entering Greater London – in a bid to ensure that...
