The Nam Sana project apparently qualifies as a Clean Development Mechanism (CDM) project under the Kyoto Protocol allowing it to receive carbon emission reduction credits. The project will help result in CO2 emission reduction as it's output may displace power generation that otherwise would be based on combustion of fossil fuels. The reduction in carbon dioxide emissions is estimated to be 25,335 tons per year. View or download the CDM application document HERE .
