"Currently the consumption of solid fossil fuels (coal and petroleum coke) in Spain accounts for more than 16% share in the consumed primary energy. Associated emissions are over 20% of GHG stemming from the high carbon content of those fuels respect to other fossil fuels like gasolines, gasoils and gas. The 20% of GHG emissions are comparable to the emissions from domestic sector or road transport in Spain." (Quoted from article)
