Audit Wales has criticised the lack of progress made by organisations in tackling climate change
A spending watchdog has strongly criticised the lack of progress made by public sector organisations in tackling climate change.
Audit Wales says since a Welsh government "climate emergency" was declared in 2019 "decarbonisation" has become a lower priority for public bodies.

It says there are many examples of positive changes but the "collective ambition" for a "net zero" public sector in Wales by 2030 is unlikely to be met.
It has been estimated that it would cost at least £2.3 billion to decarbonise Welsh council buildings alone.
The Welsh government said the "2030 ambition has driven action and leadership, but it's clear that there is more work to do".
Net zero means balancing the amount of planet-warming "greenhouse" gases produced by human activities with the amount being actively removed from the atmosphere.
Effectively this means no longer adding to the total amount of these gases in the atmosphere to limit climate change.
In its new report, the spending watchdog said public bodies in all sectors recognise decarbonisation is important.
But it said: "Since 2022, financial and political pressures have caused decarbonisation to fall down the priority list.
"Public bodies told us their overall financial pressures mean they are struggling to invest in decarbonisation."
It criticised the Welsh government for not defining the "collective ambition" for net zero by 2030 as a "target".
"There are also no penalties or incentives to drive compliance. Some public bodies told us this had added to uncertainty around the level of priority to attach to carbon reduction."
On spending, it added that public bodies had made "limited progress" overall in understanding how much it will cost to decarbonise in the near or longer term.
"Where public bodies have estimated the longer-term cost, some described it as unaffordable."
Ann-Marie Harkin from Audit Wales said: "We can list positive examples, but not enough progress has been made overall, and we owe it to future generations to do better."
