"History will be the judge of what has happened in Cancun." These are the last lines of the Bolivian Government's press release yesterday about the outcome of the climate negotiations here in Cancun. The talks ended here today after two weeks of negotiations by a 192 governments. It is a deal that will be remembered by our future generations as one that killed the climate treaty, unless we radically change course.

Witnessing standing ovations and applause in the closing hours over negotiating texts that basically kill the Kyoto Protocol and make emissions reductions voluntary for all governments fills me with a profound sense of disillusionment (you can view the final plenaries here). Disillusionment at the utter lack of leadership exhibited by virtually every government except Bolivia and disillusionment at the role that many environmental and development groups played in legitimizing these governments' actions.

The compromise arrived at Cancun was a coup for the United States. The U.S. came in with nothing to offer in terms of binding commitments to reduce its greenhouse gas emissions and yet managed to effectively push for voluntary targets. The source of these targets is the "Copenhagen Accord" that President Obama negotiated by cornering a few key countries in a back room in the last hours of the climate negotiations a year ago.

"There is only one way to measure the success of a climate agreement, and that is based on whether or not it will effectively reduce emissions to prevent runaway climate change. This text clearly fails, as it could allow global temperatures to increase by more than 4 degrees, a level disastrous for humanity," says Bolivia.

Sadly, Bolivia was set up as the scapegoat at the meeting - portrayed as the only country standing in the way of multilateralism and progress on a climate deal. "The perfect is the enemy of the good," they said.
