In these first two charts produced by Clark that show the gap between each nation's percentage target and actual percentage change between 1990 and 2010, he finds that "there are more successes than failures and the sum of emissions from nations with Kyoto targets have fallen significantly." European countries appear to have performed well in reducing their carbon footprint, but "[t]he European picture is more complex than these charts suggest because under the European Trading Scheme companies across the continent can trade emission permits between each other. Once these traded emissions are taken into account some countries move around - most noticeably Italy which switches from being ahead of its target to substantially behind."
Meanwhile, the third chart shows that the increase of carbon emissions in the rest of the world, particularly China and other emerging economies, have nullified the success of European countries. It is important to note that this growth is largely driven by the production and export of goods to developed nations, which undermines the impact of Kyoto on a global scale. "According to one study I reported on last year," adds Clark, "when you look at total carbon footprint of each nation (including imports and excluding exports), the progress made under Kyoto looks extremely poor, with Europe's savings reduced to just 1% from 1990 to 2008 and the developed world as a whole seeing its emissions rise by 7% in the same period."
The last chart shows that global carbon emissions have been increasing steadily over the past decade with no sign of slowing down. "In that sense, the Kyoto protocol has been a failure," admits Clark. "But it was unquestionably an important first step in global climate diplomacy. The question is whether a more ambitious second step will follow in time to avoid unacceptable risks of devastating climate change."
