Climate change

Climate change is the way the world's climate is changing as a result of the level of gases in the atmosphere.

We explain how we are currently working to tackle the causes and effects of climate change in our Climate Change Strategy for Wales.

We have also introduced legislation in Wales which puts sustainable development at the centre of government and the public service in Wales. The Well-being of Future Generations (Wales) Act 2015 places climate change at the heart of the government, requiring a whole government approach. The Environment (Wales) Act 2016 complements this by establishing a clear statutory basis for decision-making, fully recognises the central importance of climate change. 

Unchecked climate change is one of the most serious global threats the world faces. It threatens the basic elements of life for people and environments around the world – for example, access to water, food production, health and the use of land.

We can do something about climate change, if all of us work together. As a society we need to do 2 things to tackle the challenge of climate change:

  • reduce the greenhouse gases we produce by changing the way we produce and use energy
  • prepare for the changes that are already happening because of the greenhouse gases which have already been produced.
