Davos Leonardo Di Caprio

Oscar nominee Leonardo Di Caprio has called on businesses to do more to help tackle climate change.

Di Caprio - along with musician Will.i.am, Danish artist Olafur Eliasson and Chinese actress Yao Chen - was awarded a Crystal Award at the World Economic Forum for his work as an environmental activist. The Crystal Awards "celebrate artists who not only excel in their art, but also help to improve the world around them".

In a speech on the first day of the World Economic Forum, Di Caprio said "enough is enough" and called for business leaders and politicians to 'do more' to protect the planet.

He said: "We simply cannot allow the corporate greed of the coal, oil and gas industries to determine the future of humanity.

"Those entities with a financial interest in preserving this destructive system have denied and even covered up the evidence of our changing climate. Enough is enough. You know better. The world knows better. History will place the blame for this devastation squarely at their feet.''
