I’m not sure if this was meant to be funny, but the Wikipedia entry for “Kyoto Protocol” says this in its subsection on Russia:
The Kyoto Protocol limits emissions to a percentage increase or decrease from their 1990 levels. Since 1990 the economies of most countries in the former Soviet Union have collapsed, as have their greenhouse gas emissions. Because of this, Russia should have no problem meeting its commitments under Kyoto, as its current emission levels are substantially below its targets.
So there you have it. If our economy collapses, we may yet meet Kyoto.
