I'm not sure exactly what this means, but in general, I think it's fair to say that the US has taken a more market-driven approach that includes working with industry to decrease carbon emissions. During the same time frame the EU, China, and other nations and regions that tend towards more heavy handed top-down regulatory approaches to problems such as this seem to be having trouble making progress and are in fact still headed in the wrong direction.
The available data does not support your speculation.
