Lib Dems call for 'real action' to tackle climate change
Plans to cut Wales' net greenhouse gas emissions to zero and meet its electricity needs entirely from renewable sources by 2050 have been announced by the Liberal Democrats.
Halving the energy used for heating and electricity by 2030 is also among their environmental policies for May's assembly election.
Lib Dem AM William Powell said Wales must do more to tackle climate change.
It was time for "ambitious leadership" on the environment, he added.
