Professor Mark Maslin [UCL Geography] said many targets in their assembly election manifestos were below those of central government.

He warned Wales could be "left behind" on tackling global warming despite having "several natural advantages". …

Professor Maslin, who was commissioned by BBC Wales to examine the four main parties' manifesto pledges, said that some of the parties appear to be unaware of the targets being set at a UK level for cutting CO2 emissions.

"They're in danger of being left behind with these pledges," he said.

"I think the parties could go much further... particularly as all the parties are very keen on renewable technologies like wind and tidal power, which are perfect for Wales." …
