Volvo has launched an application for the iPhone that details all the gases emitted by new cars, beyond the usual CO2 figure.
The Emissions Equality app reveals how much every car on sale today produces in terms of carbon monoxide, oxides of nitrogen, hydrocarbons and particulates. The company says that it is these gases that contribute to the UK's unenviable record of having one of the highest rates of asthma in the world.
The point of the app is to show which cars are better or worse in terms of their effect on human health. The most startling fact is that the variances are far bigger for air quality than they are for CO2. Whereas the CO2 of most cars are between 100g/km and 300g/km, the variance for overall air quality emissions ranges from 49mg/km for the best car (a Skoda Yeti 1.2) to over 2,000 mg/km for the worst (a Cadillac Escalade). That means the worst car emits over 20 times more harmful air-quality emissions than the best.
The app has been developed in association with Clean Green Cars, who analysed all the data from the official Vehicle Certification Agency and built the app for Volvo. It is free to download and can be found under the name 'Emissions Equality' in the app store.
