Chapter 3. Implications of future climate regime architectures 139<br />

Multistage<br />

Triptych<br />

Sectoral approach<br />

• Gradual phase-in of countries, taking into<br />

account national circumstances<br />

• General framework that can accommodate<br />

many ideas and satisfy many demands<br />

• Allows for gradual decision making<br />

• Industrialized countries take the lead<br />

• Compatible with Kyoto Protocol (reporting<br />

and mechanisms)<br />

• National circumstances are explicitly<br />

accommodated<br />

• Explicitly allowing for economic growth at<br />

improving efficiency in all countries<br />

• Aims to moderate competitive concerns<br />

between industries in some sectors<br />

• Has already successfully been applied on<br />

the EU level as a basis for negotiating<br />

targets<br />

• Compatible with Kyoto Protocol (reporting<br />

and mechanisms)<br />

• Explicit considerations of national<br />

circumstances per sector<br />

• Focus on most important sectors and<br />

particular reduction options<br />

• Makes participation of many selected<br />

sectors and consequently of countries<br />

easier<br />

• If applied globally, decreases<br />

competitiveness concerns<br />

• Can be build into the Kyoto system<br />

• Requires many decisions and allows for<br />

exceptions, can lead to a complex system<br />

• Risk that stringent long-term stabilization<br />

options are lost if countries start participating<br />

too late<br />

• Incentives needed for countries to participate<br />

in a certain stage<br />

• High complexity – requires many decisions<br />

and sectoral data – makes global application a<br />

challenge, may be seen as not transparent.<br />

Best applied for a subset of countries where<br />

sectoral data is available<br />

• Agreement on projections of production<br />

growth rates for heavy industry and<br />

electricity may be difficult<br />

• Only partial coverage of sectors may make<br />

achievement of low stabilization levels less<br />

feasible<br />

• Detailed sectoral information required,<br />

currently only available for selected countries<br />

and sectors<br />

• Requires careful target setting<br />

• Certainty on the global emission level is<br />

reduced, increases in production volumes<br />

(and thus GHG emissions) are possible<br />
