The Group of Twenty (G20), a federation of the most important industrialised and emerging countries, is a crucial forum for initiating a clean-energy transition at the global level. Its member states account for nearly 80 per cent of the world's energy demand and more than 80 per cent of global CO2 emissions. The G20 brings together key players in international energy markets and international institutions along with major energy exporters. According to the International Renewable Energy Agency (IRENA), a concerted effort on the part of G20 nations could increase the global share of renewable energy sources to 44 percent by 2030.
But a successful move away from fossil fuels remains to be seen, not only in the US, where President Trump intends to withdraw from the Paris Agreement, but also among the other G20 members. Indeed, 82% of the primary energy in G20 states is still fossil-based. Since assuming the G20 presidency, in 2019, Japan has been pushing for renewed sustainable energy efforts in the G20.
