What are negotiators really talking about...?

The Guardian has "translated" key passages from the extensive draft text currently under discussion in the UN-led negotiations ahead of December’s decisive conference.

Do you want to know what 4,000 delegates and other participants at the ongoing UN negotiations in Bangkok are talking about, but are you tired just at the thought of digesting 300 pages of formal text? In that case you are advised to take a closer look at "The beginners’ guide to the Copenhagen climate conference negotiating text" produced by the Guardian.

The webpage of the British newspaper has picked key paragraphs from the draft. Take for instance this completely incomprehensible sentence: "[Comparability of mitigation efforts by [developed country Parties] [shall] [should] be ensured through: (a) [Their [magnitude] [using tonnes of CO2 equivalents as a unit of comparability] [level of mitigation ambition]]… (d) [Time frames [commitment periods] and the application of the same base year established by the Kyoto protocol]."

Here is what it really means, according to the interactive guide:

"Because the US did not ratify the Kyoto protocol, it lies on a different legal track to the countries that did. The notion of comparability is one way to bridge the gap. US targets may look weaker, it says, but they are starting from a different position and that needs to be accounted for."
