Investors and business leaders from around the world have gathered at the UN to scale up investment in clean energy sources.

Last year, investments in renewable energy such as solar and wind power hit a record US$330 billion globally, and the UN Secretary-General is calling for a doubling in investment by 2020.

The Investor Summit on Climate Risk comes one month after the signing of the Paris climate change agreement.

Dianne Penn has been speaking with Ryan Hobert, Senior Director of Energy and Climate at the UN Foundation, one of the organizers of the event.
