2.1 National emission targets and international emission trading<br />

Targets are distinguished from goals in that targets relate to actions that are<br />

near-term and specific. The most frequently evaluated type of target is that of<br />

binding absolute emission reduction target as included in the Kyoto Protocol<br />

for Annex I countries. Many authors see these as too rigid and capping<br />

economic growth; therefore a number of alternative types of emission targets<br />

have been proposed (see section 2.1.1).<br />

One crucial element is to agree on the level of the emission targets. Examples<br />

of processes to agree on a target include:<br />

- Bottom-up basis: Participating countries make proposals (pledges) for<br />

individual reductions. This approach has the risk that proposed<br />

reductions may not be sufficient for the stabilization levels desired.<br />

- A common formula could be agreed upon, which could subsequently<br />

be modified by negotiations.<br />
