So let me get this straight. It takes between 21 to 35 days for a Russian oil tanker to get to US ports to be offloaded. It takes between 35 and 60 days for a tanker from the Middle East to make the same trek.
The average tanker burns 2,6 gallons of diesel fuel per hour. For every one gallon of diesel fuel burned, it creates 22.4 pounds of CO2 emissions. Averaging the travel time of the tankers, that's 2.7 million tons of CO2 per trip. In comparison, our vehicles create between 6 and 9 tons per year.
Without going into all the equations of how many tankers come to the US per year, let alone our exports, will someone please explain to me how drilling our own oil and moving it through pipelines, along with importing oil from Canada via a pipeline will not be more environmentally "green" for the world.
