Does the CDM discourage emission reduction targets in advanced developing countries?

Under the Kyoto Protocol, developing countries can voluntarily participate in climate change mitigation through the Clean Development Mechanism (CDM), in which industrialized countries, in order to meet their mitigation commitments, can buy emission reduction credits from projects in developing countries. Before its implementation, developing-country experts opposed the CDM, arguing that it would sell-off their countries’ cheapest emission reduction options and force them to invest in more expensive measures to meet their future reduction targets. This ‘low-hanging fruit’ argument is analysed empirically by comparing marginal abatement cost curves. Emissions abatement costs and potentials for CDM projects are estimated for different technologies in eight countries, using capital budgeting tools and information from project documentation. It is found that the CDM is not yet capturing a large portion of the identified abatement potential in most countries. Although the costs of most emissions reduction opportunities grasped are below the average credit price, there are still plenty of available low-cost opportunities. Mexico and Argentina appear to use the CDM predominantly for harvesting the low-hanging fruit, whereas in the other countries more expensive projects are accessing the CDM. This evidence at first sight challenges the low-hanging fruit claim, but needs to be understood in the light of the barriers for the adoption of low-cost abatement options.
