From the information in the graph we can say that:

• power stations produce about 1.5 times the emission of residential activities

• residential activities produces about the same amount of emissions as waste disposal

• fossil fuel retrieval produces more emission than transportation of fuels

• industrial process produce about 5 times the emissions of waste disposal & treatment
