By means of a theoretical model, bootstrap resampling and data provided by the International Commission On Large Dams (ICOLD (2003) World register of dams. we found that global large dams might annually release about 104 ± 7.2 Tg CH4 to the atmosphere through reservoir surfaces, turbines and spillways. Engineering technologies can be implemented to avoid these emissions, and to recover the non-emitted CH4 for power generation. The immediate benefit of recovering non… 
Conventional energy generation techniques such as coal and oil power plants release large amounts of greenhouse gases (GHGs) due to fossil fuel combustion while renewable energy sources,

A substantial revision of carbon emission from the global hydropower reservoirs is shown by considering reservoir surface area, drawdown zone and reservoir downstream.
The urgency of assessing the greenhouse gas budgets of hydroelectric reservoirs in China
China, already the largest generator of hydroelectricity, plans to accelerate dam construction. This has led to warnings that increased emissions of greenhouse gases, particularly methane, from
Methane and CO2 emissions from China’s hydroelectric reservoirs: a new quantitative synthesis
This study provides the first evaluation of the CO2 and CH4 emissions from China’s hydroelectric reservoirs by considering the reservoir water surface and drawdown areas, and downstream sources (including spillways and turbines, as well as river downstream), and concludes that a substantial revision of the global carbon emissions from hydroelectric reservoir is warranted.
Greenhouse Gas Emissions From Hydroelectric Dams in Tropical Forests
Hydroelectric dams are not necessarily sources of “clean energy” because they produce greenhouse emissions that can be substantial. Carbon dioxide (CO2) is emitted by above-water decay of trees left

The Greenhouse gas (GHG) emissions turns out to be one of the most important factor contributing to global warming significantly. Literature revealed that reservoirs too can be an important source of
Policy considerations for greenhouse gas emissions from freshwater reservoirs.
Emerging concern over greenhouse gas (GHG) emissions from wetlands has prompted calls to address the climate impact of dams in climate policy frameworks. Existing studies indicate that reservoirs can
Assessment of Greenhouse Gas (GHG) Emission from Hydropower Reservoirs in Malaysia
This paper presents a preliminary assessment of greenhouse gas (GHG) emissions from all major hydropower reservoirs in Malaysia from the period of 1930–2017. The GHG emissions are calculated based on
Repercussion of Large Scale Hydro Dam Deployment: The Case of Congo Grand Inga Hydro Project
The idea of damming the Congo River has persisted for decades. The Grand Inga project, of up to 42 GW power generation capacity, can only be justified as part of a regional energy master plan for


Greenhouse gas emissions from hydroelectric dams are often portrayed as nonexistent by the hydropower industry, and have been largely ignored in global calcu1ations of emissions t"rom land- • use
Do Hydroelectric Dams Mitigate Global Warming? The Case of Brazil's CuruÁ-una Dam
Hydroelectric dams in tropical forest areas emit greenhouse gases, as illustrated by the Curuá-Una Dam in the Amazonian portion of Brazil. Emissions include carbon dioxide from decay of the
Hydroelectric Reservoirs as Anthropogenic Sources of Greenhouse Gases
The ever-increasing demand for energy over the recent development of societies has spurred the construction of hydroelectric facilities. Since dams were first used to generate hydropower around 1890,
Introduction As scientists and governments become increasingly concerned about the growing evidence of global warming, reducing the emissions of greenhouse gases is gradually emerging as a common
Methane stocks in tropical hydropower reservoirs as a potential energy source
Several studies over the last decade have shown that tropical reservoirs may constitute an appreciable source of methane (CH4) to the atmosphere. Here, we show that the use of low-cost, innovative
Brazil’s Samuel Dam: Lessons for Hydroelectric Development Policy and the Environment in Amazonia
Brazil’s Samuel Dam, which formed a 540-km2 reservoir in the state of Rondônia in 1988, provides lessons for development decisions throughout Amazonia and in other tropical areas. The decision to
Methane and carbon dioxide emissions from tropical reservoirs: Significance of downstream rivers
Methane (CH4) and carbon dioxide (CO2) concentrations and water‐air fluxes were measured in three tropical reservoirs and their respective rivers downstream of the dams. From reservoirs, CH4 and CO2
Carbon dioxide and methane emissions and the carbon budget of a 10-year old tropical reservoir (Petit Saut, French Guiana)
The emissions of carbon dioxide (CO2) and methane (CH4) from the Petit Saut hydroelectric reservoir (Sinnamary River, French Guiana) to the atmosphere were quantified for 10 years since impounding in
First assessment of methane and carbon dioxide emissions from shallow and deep zones of boreal reservoirs upon ice break-up
Most studies dealing with greenhouse gas (GHG) emissions from large boreal reser voirs were conducted during the ice-free period. In this paper, the potential methane (CH4) and carbon dioxide
