This infographic shows emissions data from the UN and PBL since 1990. Overall, there have been more winners than losers amongst nations with Kyoto targets, and emissions as a whole have decreased.
Sadly, this has not been reflected in the developing world (see 2nd chart), with China driving 60% of the global increase in carbon emissions since 1990. Indeed, the surge in fossil fuel usage since the late 90's has been almost entirely driven by developing countries (see chart 3, developing countries are represented by the purple area).
But we can't blame it all on developing nations… Many activists argue that developed nations have simply exported their carbon burden elsewhere (via imports). In fact, according to standard data, developed countries have reduced their CO2 emissions by around 2% since 1990, yet if you add back the carbon cost of imports, the true change has been an increase of around 7%.
So has the Kyoto Protocol worked? Well, global CO2 emissions have showed no sign of abating (last chart), in that respect, it has been a failure. However, as the only international treaty of its kind, the Kyoto Protocol has been an extremely important first step in global climate diplomacy.
