You're all correct!
Transport (cars, trains, busses, canal boats etc) account for 10% of CO2 emissions in the UK. But also they account for a far greater contribution of green taxation. The statistics for "cars" don't always include the caveat that data for trains and public transport is lumped in too. It's misrepresentation through statistics.

As for climate change, I'd take it more seriously if it wasn't for the plethora of hugely disproportionate green taxes we're going to have to pay over the next twenty five years. It's a skint politician's dream; the mother of all guilt taxes.

Anyhoo...

If we all gave up the internal combustion engine tomorrow and moved to electric cars, the power generation infrastructure couldn't cope.

Nuclear power is promising, but expensive and believe it or not we're running out of uranium. We only have enough for 200 years based on current useage, that doesn't include the new generation of nuclear plants planned.

A better solution would be to invest heavily in fusion power. However, Brown et al believe that instead hugely expensive and inefficient wind power is the way to go.

Mmmmnnnnnnggggg!

Wave power is a much more efficient short term bet.
