Carbon dioxide emissions from transportation are now thought as the top source of green-house gases.One of the most effective ways to reduce your carbon footprint is to reconsider how much,and how often,you travel. Going car free for a year could save about 2.6 tons of carbon dioxide,accord...
2) emissions come from the energy people use every day—at home and when they travel. In order to generate that energy, fossil fuels(coal oil and gas)are burnt, and these produce greenhouse gases—in particular CO2. Car emissions are a major problem, but the truth is that more CO...
The non-energy use of fossil fuels is a source of carbon dioxide (CO 2) emissions that is not negligible and has been increasing substantially in the last three decades. Current emission estimates for this source category are subject to major uncertainties. One important reason is that non-ener...
