Tomorrow's cities: Stockholm turns green


Smart is a word that has long prefaced a whole range of technology, from watches to fridges to homes.
It might sound cool to marketers, but consumers are increasingly questioning just how clever these devices really are.
Now, cities are jumping on the bandwagon and giving themselves the same title whenever they implement technology solutions.
For some, that involves flashy and expensive command-and-control centres from which they view traffic flow and data collected from sensors around the city.
Sweden's capital, Stockholm, has taken a different, quieter approach, but, along the way, has garnered over seven million euros (£5.9m) of EU money and become a leading example of how to do "smart".
It has been designated as an EU "lighthouse" city - alongside Barcelona and Cologne - meaning the projects it implements, if successful, can then be copied in other European towns.
Stockholm's interpretation of smart is about becoming greener - it hopes to be fossil-fuel free by 2040 and sees eco-policies as the smartest thing not only for the city but for the planet.
Stockholm is already pretty eco-friendly.
Bio-fuel, generated from sewage, is available at petrol stations around the city, and regularly used by taxis and cars.
And now, the city wants to extend its use to larger vans and lorries, which are particularly polluting, and explore ways to make the fuel more efficient.
"One hundred people going to the toilet powers one car, but if we add organic household waste, that goes down to 60 people," said Gustaf Landahl, who heads up the Grow Smarter project.
