Addressing the REAL problem would be reducing and removing all tax incentives for the oil & gas industry and redirecting them to Green solutions. When the artificial price of oil shot up the demand would decrease and the pipelines wouldn't be needed. The cost would shoot up making green energy far more viable which would increase demand of it making it cheaper in the long haul. That effect would drastically reduce CO2 output from the burning of oil and provide a massive stimulation to cleaner solutions. The Greenies are smart, because that is the goal, to make our planet livable for all creatures not just a few in oil and gas.
