Ever
since a climate bill stalled in the Senate four years ago, environmental and
public health activists have been pressing Obama to use his executive
authority to impose carbon limits on the power sector, which accounts for 38 percent of the nation's carbon dioxide emissions.
Since the statutory
authority to which the commenter refers does not often exist, many uses of protected
health information that are in the
public interest (described above in more detail) would not be possible under such an approach.
