1 ) 

Carbon dioxide produced at coal-fired power stations is captured, liquefied and stored deep underground, known as carbon capture and storage.

2 ) 

Changes to rural land use leads to increased deforestation, which decreases the amount of carbon dioxide removed from the atmosphere by vegetation.

3 ) 

Increased use of concrete as a building material. Cement production involves the heating of calcium carbonate releasing carbon dioxide into the atmosphere.

4 ) 

Higher global gas and oil prices makes exploiting untapped fossil fuel reserves via processes like fracking more viable than renewable sources of energy
