The First Place Fossil goes to the United States for downgrading developed country MRV.
Comparability between those inside the second commitment period of the Kyoto Protocol and those outside is essential to underpinning a regime built on trust and transparency.
The US has been consistently blocking progress on MRV inside the talks.
This is all the more strange because in Copenhagen the US pushed hard on China to be more robust in its accounting and reporting of emissions. Now the tables have turned. If the US is serious about a 2015 deal they need to count their carbon. Their blocking is counter-intuitive. The US has some of the most robust transparency and accounting procedures in the whole world, but simply has an allergy to replicating these at an international level.
The key to securing a global binding treaty is trust; the US knows more than anyone that transparency and accountability help reassure all countries that they each are all doing what they said they would. What the US, and their minions, like Japan and Canada, are doing is corrupting their carbon accounting.
