Broad is different from general. I see breadth as a double edged sword. It does have the problems you mention. However, if the government could get sufficient buy-in, it helps because there are a large number of ways to improve per-capita CO2 emissions (e.g. improving housing insulation, increasing public transportation usage, development of CO2 scrubbing/sequestration technologies.) I feel that the real killer of challenges is actually vagueness. "Improve health care" is vague because there is no well defined goal or target that we will be able to meet.
