Chapter 2. Options for future climate change architectures 74<br />

adopting measures to address climate change, preferably in a sustainable<br />

manner. Responsibility refers to the aspect that those countries that are<br />

responsible for the problem should make greater efforts (polluter pays).<br />

Capability means that those countries that have most resources should act<br />

(ability to pay). All theses principles are included in the Convention, the<br />

principle of need in the ultimate objective; the other two in Article 3.1 which<br />

refers to their “common but differentiated responsibilities and respective<br />

capability”.<br />

As the only approach proposed by a developing country – among the ones<br />

considered here – the Brazilian Proposal specifically takes into account these<br />

principles. The whole approach is based on the responsibility principle (polluter<br />

pays), specially in historical responsibility of countries, countries receive a<br />

burden that corresponds to their cumulative historical emissions and<br />

contribution to global temperature rise. To some extent, capability and need are<br />

also supported, since only industrialized countries are given national abatement<br />

targets according to the original approach.<br />

The Multistage approach allows for sustainable economic development<br />

(need) as participants move stages only when a certain threshold, based on<br />

economic or emission development, is reached. The sustainable development<br />

stage ensures development as a first priority for newly entering countries. The<br />

principle of capability is covered to some extent, as countries are differentiated<br />

in stages. The emission per capita threshold for countries to move upward<br />

refers to the principle of responsibility. Targets assigned in each stage,<br />

differentiating reductions to all participating countries, also increase capability<br />

and responsibility principles.<br />

The Tryptich approach allows for economic growth (need) leaving space for<br />

industrial and electricity production to grow if they do so in an efficient way.<br />

The capability principle is not explicitly addressed. The responsibility principle is<br />

addressed as in the domestic sector; those countries that have higher emission<br />

levels must reduce emissions more.<br />
