James Murray: Smart city: Leeds to trial tech that switches engines to electric when air pollution spikes

Cenex-led initiative will aim to integrate real-time emissions controls and live air quality data in a bid to tackle urban air pollution

The government's controversial air quality plan argued that cities should not introduce new charges for diesel vehicles until innovative alternative approaches to tackle air pollution had been tired first. But could that condition soon lead to UK cities embracing cutting-edge smart technologies and hybrid-electric vehicles that promise to switch to zero emission mode whenever pollution levels spike?

That is just one of the questions sparked by this week's news Leeds is to host a trial from a group of clean tech firms and research bodies that promises to demonstrate a new real-time emissions control technology.
