What is the Clean Development Mechanism? The Clean Development Mechanism (CDM) is an emission reduction mechanism established in Article 12 of the Kyoto Protocol. Under this mechanism Annex I countries can participate in the implementation of projects that reduce GHG emissions and that are physically located in non-Annex I countries. Provided certain conditions are met, they can use these emission reductions to comply with their emission reduction commitment targets under the Kyoto Protocol.
CDM offers Annex 1 countries a flexible and cost-efficient means of fulfilling a part of their Kyoto commitments, while the non-Annex 1 party benefits from foreign investment and technology transfer.
In order to qualify under the CDM, emission reductions resulting from the implementation of registered projects need to be real, measurable, and long term. Furthermore, each tonne reduction of carbon-dioxide-equivalent-emissions, once verified and certified, results in the issuance of a CER (Certified Emissions Reduction). The purchase and sale of CERs constitutes a CDM transaction.
Launched January 1 2005, the European Union Emission Trading Scheme (EU ETS) is the world's first international company-level 'cap-and trade' system of allowances for emitting carbon dioxide (CO2) and other greenhouse gases (GHGs).
The EU ETS is based on the recognition that creating a price for carbon offers the most cost-effective way to achieve the deep reductions in global GHG emissions that are needed to prevent climate change from reaching dangerous levels and for the EU to achieve the reduction targets it committed to under the Kyoto Protocol.
At present some 11,000 installations from the 27 Member States of the EU and neighbor countries including Iceland, Liechtenstein and Norway participate in the ETS. These installations belong to the power and heat generation industry and selected energy-intensive industrial sectors such as: combustion plants, oil refineries, coke ovens, iron and steel plants and factories making cement, glass, lime, bricks, ceramics and pulp and paper. These sectors account for 50% of the EU's total CO2 emissions and 40% of its overall GHG emissions. Starting 2012 the aviation sector will be included, adding to the system airlines operating within, to and from the EU zone.
The limit or 'cap' on the total number of allowances allocated creates the scarcity needed for trading. Companies that keep their emissions below the level of their allowances can sell their excess allowances at a price determined by supply and demand at that time. Those facing difficulty in remaining within their allowances limit have a choice between several options ensuring that emissions are reduced in the most cost-effective way.
