Some of the issues One important issue under discussion in the lead up to at [[COP15]] include resolving the baseline year that specified reduction targets will be measured against and the duration of the second commitment period; (See [[Post-Kyoto Protocol base year for measuring greenhouse gas emission cuts against]] for further background information) and the medium and long-term proposed greenhouse gas reduction targets; (See [[Greenhouse gas emission reduction targets]] for further background information). Another important issue is whether a new agreement will be expanded to include greenhouse gases that are currently excluded from the Kyoto Protocol; (see . See [[Greenhouse gases omitted from the Kyoto Protocol]]).
