Different emissions have different levels of global warming potential. If carbon dioxide has a global warming potential of 1, then Methane has a Global Warming Potential of 28-36 over 100 years [0]. I wouldn't even single out carbon dioxide per se. If you're going to start an emissions tax and do it right, you might as well target all green house gas emissions and base the tax rate off their global warming potential which takes into account both the energy they absorb and their longevity in the atmosphere.
