In June 2015, carbon credits amounting to 446 t of CO2 were issued for a Clean Development Mechanism (CDM) project developed and implemented in Vietnam’s Mekong Delta aimed at reducing greenhouse gas (GHG) emissions through the introduction of biogas digesters (BDs) to farm households. Subsequently, the project was evaluated in terms of GHG emission reductions (i.e., carbon credits issued), receptiveness of farm households to the technology, and economic benefits to these families. Findings confirmed that BDs provide concrete reductions in GHG emissions and are beneficial to install in such scenarios. Currently, a new international framework for post-2020 global warming mitigation is being considered by the United Nations Framework Convention on Climate Change (UNFCCC), in which all signatory countries would participate, including the developing countries that have not yet been mandated to make reductions. These evaluation results present a potential policy direction for developing countries to reduce their GHG emissions.
