The Bali Action Plan calls for "ensuring the comparability of efforts" among developed Parties. The ability to compare pledges is seen as a vital element of ensuring a fair, equitable, and transparent global agreement. There are many metrics of comparability that one could examine, including level of effort taken domestically versus via international offsets, abatement costs, historical responsibility, among others, and metrics could be combined and weighted differently. Here we examine one metric of comparability: percent change in absolute emission reductions.
