Antonio- The Kyoto Protocols deal primarily with Carbon Dioxide (co2). Did you know that North America ABSORBS more co2 than it emits? That is correct. Due to the large forests and agricultural areas (whose plants absorb co2 and emit oxygen as part of Photosynthesis)USA and Canada are "importers" of co2, not "exporters" like Western Europe.

Kyoto fails to address the emesions of vastly expanding industrial states like China, Mexico and India. Kyoto sounds good but won't be very effective in practice, which is why every western European gov't. has refused to implement it, not just the US.
