If we have a new legislation that significantly reduces emissions of SO2, NOx and mercury, we can eliminate many of the individual programs that apply to the power generation sector and replace them with a system that will reduce the administrative burden on industry and governments, use market-based incentives to keep compliance costs low, and provide the industry with more certainty about its future regulatory obligations.
If the emissions were reduced then there would not be a need for as many programs, which in turn could use the funding towards ways to keep costs down.
