Delegates at the Paris climate talks must heed the success of green bonds, which underlines the boost financial solutions can give to the global warming battle

Green bonds have been described as a game changer in the fight against global warming. With more than $50bn (33bn) in green bonds expected to be issued this year - and more than $532bn mobilised in wider mitigation and adaptation projects - delegates at this week's climate talks in Paris will surely sing their praises.

The success of the green bond can be credited to its easy re-imagining of a mainstream financial tool. Its wide adoption has revealed an appetite among diverse investor groups to put money into climate-friendly projects - from resilient infrastructure to energy efficiency - that offer a return for both the investor and the planet.
