although it is not part of it, through publishing comprehensive reviews every<br />

five years of the status of climate change and climate-change science.<br />

The UNFCCC created a global policy architecture with four key elements: a<br />

general long-term environmental goal; a near-term environmental goal with<br />

specific quantitative targets; concerns about equity; and preference for cost-<br />

effective implementation.<br />

The ultimate objective of the UNFCCC is the “stabilization of greenhouse gas<br />

concentrations in the atmosphere at a level that would prevent dangerous<br />

anthropogenic interference with the climate system” (Article 2). It was not<br />

defined or quantified what was meant by dangerous. Some suggested<br />

quantifying this objective with a long-term greenhouse gas concentration<br />

stabilization goal (e.g., 550ppm – about double pre-industrial CO2<br />

concentrations) or a temperature increase stabilization goal (e.g., 2ºC above<br />

current levels). However, nothing has been agreed. Also, it was not specified a<br />

time period for action. The UNFCCC states that “such a level should be<br />

achieved within a time-frame sufficient to allow ecosystems to adapt naturally<br />

to climate change, to ensure that food production is not threatened, and to<br />

enable economic development to proceed in a sustainable manner” (Article 2).<br />

The UNFCCC also set a near-term environmental goal with specific<br />

quantitative targets. Industrialized nations, consisting of most members of the<br />

Organisation of Economic Co-operation and Development (OECD) and twelve<br />

economies in transition (countries in Central and Eastern Europe, including<br />

some states formerly belonging to the Soviet Union) were expected by the year<br />

2000 to reduce emissions to 1990 levels. As a group, forming the so-called<br />

“Annex 1” countries - they are listed in the first annex to the treaty - they<br />

succeeded. This compliance was not impressive, as most of them met their goal<br />

through substantial economic decline and transformation (e.g., Russia and<br />

Germany) or non-climate-related energy sector reforms (e.g., the United<br />

Kingdom).<br />
