WWF-Brazil published a study in 2020 called the "Sustainable Power Agenda" examining Brazil's energy production paths and challenges. In 2005, the government started prioritizing fossil fuel plants like diesel, coal and natural gas, approving 3,286 MW of capacity. This represented a 2.8% increase in Brazil's carbon dioxide emissions and 11% increase for the electric sector. As a result, WWF-Brazil concluded that choices in Brazil's electricity sector over the next 15 years would be critical for energy security, economic competitiveness and environmental sustainability.
