Factsheet
Hydropower is often believed to be an inherently “climate-friendly” technology. But scientific studies indicate that the rotting of organic matter in reservoirs produces significant amounts of the greenhouse gases carbon dioxide, methane and nitrous oxide. The warming impact of tropical reservoirs can be much higher than even the dirtiest fossil-fuel power plants.
