As one of the largest polluting countries in the world the US would already have had sanctions imposed if it weren't the trigger happy nation it is. It boggles the mind knowing it can get away with so much damage to this planet. China and India, also major polluters, are taking constant heat over it but the US is not. The only option is to stop buying american (little and of low quality as it is) and impose harsh tariffs on any products made without consideration for the environments.
As with cars. Fortunately there almost no us made cars in europe as they damage the environment.
