Climate finance: The public sector can't do this alone

We’re doing a lot of talking and listening here at COP 20 in Lima about climate finance – how hundreds of billions of dollars were invested globally last year to clean up the air, get efficient energy to more people, make agriculture more productive, and build resilience to extreme weather events.
We all know and acknowledge much more still needs to be done – the International Energy Agency and others believe we need at least $1 trillion dollars of new investment each year to address climate change.
There’s no way that public money alone can meet that goal. We need to find ways to catalyze the limited public funds we have to unlock private investment. That, of course, means investors need to have the confidence that the right policies are in place to make long-term investments for the climate.
