In the UK, Lib Dems are calling for a total, outright ban on gas cars by 2040. The UK government is trying to reduce greenhouse gas emissions 60 percent from 1990 levels by 2050. They think this would be a great way to reach those targets. 10 years without gas cars would probably help... a lot.

"We need to provide certainty to the car industry and every other industry that is involved in this area to make sure that by 2040 we are using alternative non-carbon emitting fuels" says spokesperson environment spokesman Chris Huhne. What's clearer than a ban?

Chris says there is precedence for such a change occurring in that time period. The switch from steam engines to internal combustion engines happened in the same time. Lib Dems have other ideas for dealing with climate change like more taxes.
