Changing economic behavior with public campaigns has a pretty much zero success rate. Anyone remember Pres Ford's "WIP" buttons (Whip Inflation Now)? It had the hubris that inflation could be stopped if only people would just stop raising prices.

Even as a kid, I laughed at the absurdity of that campaign. Of course it had zero effect.

Something that will work is to tax pollution, i.e. a carbon tax. Making it more expensive will do far more to influence behavior away from it than any marketing campaign. And besides, it raises spending money for the government, too.

Using the tax system to "internalize the externalities" (economist jargon) is an efficient and effective way to do it.
