5 Min Read BARCELONA (Thomson Reuters Foundation) - Investment in clean energy in emerging and developing economies needs to rise by more than seven times, topping $1 trillion per year by 2030, to put the world on track for net-zero emissions by 2050, the International Energy Agency (IEA) said on Wednesday. In a report carried out with the World Bank and the World Economic Forum, the IEA said that, without far stronger action, energy-related carbon dioxide emissions from those economies – mostly in Asia, Africa and Latin America – would grow by 5 billion tonnes over the next two decades. By contrast, carbon emissions are projected to fall by 2 billion tonnes in advanced economies and plateau in China.
