It's technically possible for that to happen through voluntary measures, but the track record.... I'm looking down at the graph of greenhouse gas emissions by sector from 1990 to now, which I can provide to the committee after this hearing. The experience to date has been that, even when the oil and gas sector increases the efficiency with which it pollutes, essentially, emissions intensity improvements, those benefits have been outweighed by larger increases in production.
Something is going to be needed to change that curve to better mirror, perhaps, the electricity curve, or some of the other curves that are flat, at least, if not decreasing. Something is needed to get a handle on oil and gas.
