Pedestrians walk along a footpath in front of a massive chimney billowing smoke for a coal-burning power station in central Beijing January 12, 2012. China, with 1.34 billion people, is the world's biggest emitter of greenhouse gases which totals around a quarter of the world's CO2. This is more than the United States, historically the world's top emitter. A recent study from U.S. researchers states that China could peak in emissions by 2030 or earlier, with Chinese demand for appliances, buildings and much industry reaching "saturation" around then. Beijing has resisted officially spelling out when its emissions could peak saying they should be allowed to grow out of poverty while rich nations lead the way in cutting carbon.Credit: REUTERS

Global energy CO2 emissions could be cut by 70 pct by 2050 -IRENA

By Nina Chestney | March 20 2017

(Reuters) Global energy-related carbon dioxide (CO2) emissions could be reduced by 70 percent by 2050 and completely phased out by 2060, research by the International Renewable Energy Agency (IRENA) showed on Monday.

To help achieve this, the share of renewable energy in primary energy supply would need to increase to 65 percent in 2050 from 15 percent in 2015, the report said.

An additional $29 trillion of energy investment would be needed to 2050, equivalent to 0.4 percent of global gross domestic product (GDP).

Such investment should provide stimulus that, with other policies supporting growth, would boost global GDP by 0.8 percent in 2050.

Globally, 32 gigatonnes of energy-related CO2 were emitted in 2015. Emissions need to fall to 9.5 gigatonnes by 2050 to limit global warming to no more than 2 degrees Celsius above pre-industrial temperatures, IRENA said.
