From its piece:

Global investments in clean energy need to double by 2020 to avoid missing climate change targets, the International Energy Agency (IEA) said on Monday, calling on governments to spend more on technologies such as carbon storage and solar power.

Some $23.9 trillion in investments are required by 2020 and $140 trillion by the middle of this century, when governments aim to keep the average rise in global temperatures to below 2 degrees Celsius, the Paris-based organization said.
