The purple bus and the polar bears ... can the Politics Bus go green?
David Cameron is getting a windturbine for his house ... Peter Hain fought back with a roof full of solar panels.
So can we turn our little bus green?
Since the bus took to the road in 1980, it has churned out a staggering 95.6 tonnes of Carbon Dioxide.
But every year, British motorists pump 153m tonnes into the atmosphere.
That is 12% of the UK's total production, according to DEFRA.
In the arctic, it is literally melting the ice.
These pictures show what's happened to the polar ice cap since 1980 - it is now at its lowest recorded level ever.
And even the US government, no green tub-thumpers, now agree that the earth is too warm.
"If our current models are right, there will be no sea ice here by 2050", says Dr Jane Waterman.
Jane is an independent scientist, funded by the federal government, not a green pressure group.
Standing on the ice by Hudson Bay, she told a team from BBC Bristol how the weather was wrecking the Arctic.
"If there is no ice, there are no polar bears - simple as that."
Colin Jackson, one of the wildlife cameramen with her, explains why the bears are so dependent on ice.
"You have to remember these animals don't eat for the whole summer already" he says, "they hunt seals, and the seals live out on the ice.
"So until the Bay freezes, they starve."
The Hudson Bay froze a month later than usual in 2005.
All because the climate is changing, and most people accept that CO2 is part of that problem.
Which brings us back to our little bus. Can we cut our carbon?
We're going to investigate what options there are for the ordinary motorist.
