The negotiations deal with the post-2012 period. You may be referring to our Kyoto Protocol target, which covers the first commitment period, which is 6% below 1990 levels as a five-year average, 2008 to 2012. That is expressed in an absolute number of about 2.7 gigatonnes as our five-year carbon budget under the first commitment period of the Kyoto Protocol.
