The Welsh Parliament could become the first in the world to officially declare a Climate Change emergency.
The Welsh Government has today backed a Plaid Cymru motion which is due to be debated in two days time.
The support almost guarantees that it'll get the green light at the Senedd on Wednesday.
Shadow environment minister Llyr Gruffydd said: "We are glad to see that the Labour Welsh Government have listened to Plaid Cymru and have backed our call to declare a Climate Change emergency just two days ahead of our debate on the issue. On Wednesday, we look forward to the Welsh parliament becoming the first in the world to officially declare such an emergency by backing Plaid Cymru’s motion in the Assembly. We congratulate all campaigners including Extinction Rebellion and the school strikers for their tireless activism. This is their achievement.
"But this cannot be more empty grandstanding from Labour. This must now mean a real and immediate commitment to tackling climate change head on with concrete action and the political will to see it through. This includes scrapping the environmental disaster that is the M4 Relief Road, divesting from fossil fuels, and ensuring that sustainability and climate is a part of the new curriculum.
"Otherwise this declaration will mean nothing at all."
Shadow Minister for the Environment and Rural Affairs, Andrew RT Davies AM, said: "Huge strides have been made over the past few decades, and the UK has played a leading role working towards a global deal to reduce greenhouse gas emissions through the Paris Agreement, but it’s clear more needs to be done to tackle climate change.
"Since 1990, the UK has cut emissions by more than 40 per cent while growing the economy by more than two thirds, the best performance on a per person basis than any other G7 nation. However, regrettably, Wales has lagged behind the rest of the UK with emissions only falling by 19 per cent between 1990 to 2015.
"Only recently Labour’s Environment Minister set emissions targets that actually fell short of those demanded by the Paris Agreement, so we await to see what action will be taken to ensure this isn’t just another empty pledge from a Welsh Labour Government that has consistently failed to deliver on its promises during its twenty years in government."
