What does CDM stand for in the context of environmental projects?

The correct term in the context of environmental projects is Clean Development Mechanism. This mechanism was established under the Kyoto Protocol, intending to promote sustainable development by allowing industrialized countries to invest in greenhouse gas reduction projects in developing countries as a strategy to meet their own emissions reduction targets.

Through the Clean Development Mechanism, projects such as renewable energy installations and energy efficiency improvements can be implemented in developing regions. In turn, these projects generate Certified Emission Reductions (CERs) which industrialized countries can use to offset their emissions, thus fostering an avenue for technology transfer and sustainable practices while addressing climate change.

The other terms listed do not represent recognized mechanisms or concepts established in the environmental projects framework and do not align with the goals set by international environmental agreements.
