State Help On Ocean Acidity

This might be a promising path in the U.S., given the example of the influence that states like California are beginning to have on vehicle emissions standards and all. Says AP:

In the settlement agreement, the [U.S. Environmental Protection Agency] said it would take public comment on the increasing acidity of oceans, on ways states can determine if their coastal waters are affected, and on how states can limit pollutants that cause the problem.

Such measures could include regional cap-and-trade systems to limit carbon-dioxide emissions from the burning of fossil fuels or requiring industrial plants to reduce their emissions as a condition of any discharge permits granted under the Clean Water Act, Sakashita said.
