What is the difference between REDD and CDM

Clean Development Mechanism (CDM) & REDD

The Clean Development Mechanismis one of the "flexible mechanisms" provided for in the Kyoto Protocol. The rich countries can finance projects to reduce emissions in developing countries and have these reductions offset against the fulfillment of their own obligations. The most important criterion when approving CDM projects is "additionality". This is determined by comparing the emissions after project implementation with the emissions in a reference scenario ("what would have happened without the project?") - a weak point in the system. Which projects can be financed depends on the price of the reduction certificates on the carbon markets.
Motto of the development so far (quite intentional): "The cheapest first". Hence the large proportion of the projects for the combustion of HFC-23, a residue in coolant production and extremely potent greenhouse gas (see graphic). The price of the certificates was well above the reduction costs and ensured the plant operators (especially in China) enormous profits. In 2007, on the other hand, projects in the fields of renewable energies (including hydropower), increasing energy efficiency and switching fuel - such as gas instead of coal - dominated. The World Bank believes that more efficient coal-fired power plants should also be eligible for the CDM.

REDD (Reducing Emissions from Deforestation and Degradation)
Forestry and deforestation are responsible for more than 17% of all greenhouse gas emissions - hence their central role in a future climate agreement. A new proposal in the climate negotiations provides for credits for avoiding deforestation etc. to be included in global emissions trading. In addition to endangering the land rights of indigenous forest peoples, the risks also include flooding the carbon markets with these - as expected cheap - reduction certificates. Heated discussions are therefore ensured.
