This means that beginning in 2020, the wealthier countries of the Global North must initiate a transition to renewables, cutting CO2 emissions by 8 per cent each year for a decade, aiming to completely decarbonise by 2030. At that point the countries of the Global South will embark on the same journey at the same pace. This will mean that by 2040, in spite of growing populations with rising expectations, they will have transitioned too. So in a little more than two decades, the world can go beyond fossil fuels in meeting all of its energy needs – not just electricity.
