Both public and private sectors must lead in implementing Paris deal

FRENCH President Emmanuel Macron is hosting a major One Planet climate summit on Tuesday, with dozens of world political leaders and a host of other key players, including Bill Gates, Arnold Schwarzenegger and Michael Bloomberg.

The meeting, on the second anniversary of the day that the UN's landmark Paris global warming deal was agreed, will re-energise support for it, such as focusing on how public and private finance can innovate to accelerate the battle against climate change.

The Paris deal came after many years of painstaking negotiations and was agreed by more than 190 countries in a welcome shot in the arm for attempts to tackle global warming and, crucially, a new post-Kyoto framework was put in place. The more-ambitious-than-expected deal agreed to see greenhouse gas emissions peak "as soon as possible", and achieve a balance between sources and sinks of greenhouse gases in the second half of this century, with progress reviewed every five years.
