How much is the future worth to us? Our behaviour would suggest not much.

The key to changing our behaviour with regards to climate change is, say economists, for humans to start valuing the future as much as the present.

One of the most ingrained behaviours affecting carbon emissions is car use. Government efforts to persuade people to shift from cars to public transport tend to be preachy and heavy handed. But in Sweden, economists believe using "nudge" theory can create real change.

The BBC's Claudia Hammond heads to Stockholm to find out if nudge theory could encourage people to stop using their cars.

For more on nudge theory and Claudia's trip to Sweden listen to click The Selfish Ape, part one of click The Climate Connection series.
