Brazil is one of the countries in the itinerary of German Chancellor Angela Merkel’s Latin American tour. One of the items in her agenda is a German-Brazilian collaboration on renewable energy. At the same time, she emphasized the need for making biofuels sustainable, and to protect the rainforests. "Biofuels are a way to replace classic fossil-based energy sources, but only when they are grown sustainably," Merkel said. In a related development, the European Union mentioned last month, that Brazil would have to meet environmental standards if it hopes to export biofuels to Europe..
