Ranking Renewable and Fossil Fuels on Global Warming Potential Using Respiratory Quotient Concept
Figure 4
Variation of RQ with H/C ratio and O/C ratio of the C-H-O fuel. Gaseous and liquid fuels have lower RQ factor when compared to that of solid fossil and renewable fuels. CO2 in tons per GJ ≈ ; CO2 in short tons per MMBtu ≈ .
