I entirely agree with the position you're expressing. To the extent that the goals that are set and the environment that is created can continue to foster an environment where you can continue to invest economically in new technology, we will increase productivity and achieve greater energy efficiency. At the same time, as we've demonstrated over the last 20 years, we will also achieve very large and significant reductions in emissions.
So your point is well taken and valid. The only thing we're advocating is that we have to be careful in the way we set up the targets, because we can overstep economic feasibility and therefore have no economic mechanism to defend ourselves with.
