An AS-level student inspired by Steve Jobs and Mark Zuckerburg has launched an app to help mums share the school run.
ecomumy is the brainchild of Andrew Christopher, a pupil at King's College School, Wimbledon.
Andrew, 17, said he came up with the idea after watching 4x4 cars with a seven-seater capacity carrying just three passengers during his slow journey to school.
He said: "When I travelled to school I would always notice there was a lot of congestion so I wondered if there was a way to resolve this issue and reduce traffic congestion as well as CO2 emissions.
"I would like all the schools in Merton to come forward on the idea of ecomumy so they can use it as a model and help the environment."
The app, available to download from iTunes and Google Play, allows users to search for their childrens' school and co-ordinate with parents making similar journeys.
Andrew, who is preparing for maths, physics, history and chemistry exams, said he got into graphic design after designing the website of his dad's company.
He said: "My dad's company bought an Adobe Creative Suite kit and I wanted to try it out. One of his employees taught me when I was 10 and from there I started to self-teach."
After coming up with the idea for ecomumy aged 15, he made a story board, mapping out how the app would function, and sent it to developers in India.
Andrew has entered ecomumy into the CHEST competition - a European Union-led initiative inviting innovators to propose solutions to key social challenges.
