Global energy CO2 emissions could be cut by 70 percent by 2050

Global energy-related CO2 emissions could be reduced by 70% by 2050 and completely phased out by 2060, research by the International Renewable Energy Agency (IRENA) suggests.

The report, produced for the German government, says that achieving this goal would require the share of renewable energy in primary energy supply to increase to 65% in 2050 from 15% in 2015.

An additional $29tn of energy investment would be needed between now and 2050, the report says, equivalent to 0.4% of global GDP. But the transition would also boost the global economy by $19tn,
