AQUÍ FIRMAMOS el protocolo de Kioto y EEUU no y por eso son malos, pero mientras tanto aquí no paran de subir las emisiones de CO2. Pero allí:

U.S. carbon dioxide emissions dropped slightly last year even as the economy grew, according to an initial estimate released yesterday by the Energy Information Administration.



The 1.3 percent drop in CO{-2} emissions marks the first time that U.S. pollution linked to global warming has declined in absolute terms since 2001 and the first time it has gone down since 1990 while the economy was thriving. Carbon dioxide emissions declined in both 2001 and 1991, in large part because of economic slowdowns during those years.
