CLEAN DEVELOPMENT MECHANISM

The Clean Development Mechanism (CDM) is a permission outlined in the Kyoto Protocol, under Article 12. The CDM lets a country that is committed to lowering or limiting emissions under the Kyoto Protocol implement an emission-reduction project in a developing country. A carbon project such as this can earn certified emission reduction (CER) credits, which may then be sold or traded. Each CER is the equivalent of one tonne of CO2.

So the clean development mechanism makes carbon tradeable?

The CDM makes carbon into a global investment with an environmental aspect. By standardising emissions into offset instruments (CERs) each worth one tonne of CO2 it allows a market.

So the clean development mechanism allows investment in developing countries?

A CDM project may involve a village changing from polluting, fossil-fuel intensive heating to solar panels, for instance. The CDM therefore stimulates sustainable development and helps to reduce emissions. This gives industrialised countries the chance to offset their emissions and meet their emission-limitation or emission-reduction targets.

How does the clean development mechanism work?

CDM projects have to provide emission reductions that are an addition to what would otherwise have happened. That is, credits bought under the CDM have to be additional. CDM projects also have to fulfil strict criteria including registration and issuance processes.

Who oversees the CDM?

All CDM projects are overseen by the clean development mechanism Executive Board. The board is effectively answerable to those countries that have agreed with and ratified Kyoto Protocol.

How big is the CDM?

Since 2006, when the clean development mechanism started, over 1,650 projects have been registered. This has produced certified emission reductions that are equal to 2.9 billion tonnes of CO2 and CO2 equivalent.
