RE:Putting green house gas emissions into perspectiveWow. Outstanding summary Marner! Its coal that is the culprit that is most easily eliminated. Your summary on canadian oil and gas is bang on. They target us because they can and we are easy targets. One thing about natgas versus coal, stoichemetrically CH4 emits 50 % less CO2 than coal but when you take into account diesel to run the rig and frac its only 25 percent less if the rig runs on diesel or 35 percent if it runs on natgas. I think hybrid vehicles are the way to go.
