According to UN's estimates based on IAEA 1996, coal power plants are far more carbon dioxide intensive than hydropower.
However, in Vietnam's National Green Growth Strategy approved in 2012, by 2030, Vietnam has commited to reducing annual greenhouse gas emissions by at least 1.5-2 percent, and carbon emissions from energy production by 20-30 percent compared to 2010.
