Brazil is in a strategic position when it comes to energy and climate issues. It holds the presidency of the G20 nations this year and the UN climate talks – or COP30 – in 2025. This comes as the nation sees a significant reduction in deforestation in the Amazon rainforest under President Luiz Inácio Lula da Silva and new commitments to pursue low-carbon technologies, such as hydrogen, and establish a regulated carbon market. At the same time, Brazil, the biggest producer of oil in Latin America, is planning to ramp up its output. So, how is the energy transition unfolding in Brazil? And how can the country balance environmental protection and energy security?  This week host Bill Loveless talks with Thiago Barral about how Brazil plans to build up clean energy technologies, and how geopolitics shapes that strategy. Thiago is the national secretary of planning and energy transition of the Ministry of Mines and Energy for Brazil. Before his role as secretary, Thiago was the president of the Energy Research Company, a Brazilian institution responsible for energy planning studies and official state energy statistics. He joined the Energy Research Company in 2007, and also served as director of energy economics and environmental studies.
