According to Mongabay, the United Nations through its Clean Development Mechanism (CDM) is helping the developing world reduce carbon emissions by financing projects like hydroelectric dams. A new one under construction in Panama is pending carbon credit certification from CDM. Unfortunately, the dams can wipe out indigenous, fragile wildlife, arguably put something worse into the sky — and in the case of the Panama dam could displace an indigenous tribe. Excerpt:
The American firm (AES Corporation of Virginia) has requested carbon credit certification under the CDM for the project, claiming that the dam will help against global warming. However, recent research suggests that tropical dams release methane, a gas which has more than 20 times the global warming potential of carbon dioxide.
Beyond potential emissions from flooding, environmentalists say the dam threatens La Amistad Reserve, Central Americaâ€™s largest intact rainforest. Biologists have counted more than 215 mammal species, 600 birds, 115 fish, 250 reptiles and amphibians to date in the reserve, including 180 plant species and 40 bird species found no-where else in the world. La Amistad’s biological stars include the quetzal, harpy eagle, howler monkey, jaguarondi, tiger-cat, tapir, and jaguar. In January scientists from the Natural History Museum of London announced three new species of salamander from the Costa Rican side of the park, proving that there was still much left undiscovered in La Amistad Reserve.
