Leonardo Dicaprio is donating $15 million to charity.

The 40-year-old actor's self-titled foundation, which he founded in 1998 to fund efforts that protect the planet and endangered species, has pledged the generous sum to more than 30 environmental groups ''implementing innovative and impactful conservation projects around the globe.''

In a statement, the 'Wolf of Wall Street' star said: ''The destruction of our planet continues at a pace we can no longer afford to ignore. We have a responsibility to innovate a future where the habitability of our planet does not come at the expense of those who inhabit it. I am proud to support these organisations who are working to solve humankind's greatest challenge.''

Amazon Watch, National Geographic: Pristine Seas, Save the Elephants and the World Wildlife Fund are among the groups that will receive grants from the Leonardo DiCaprio Foundation to help them continue their efforts.

The Oscar-nominated star previously helped raise more than $25 million for his campaign to save wild regions and animals across the world at a charity gala last year.

Items auctioned off at the star-studded event included two ''extras'' roles in one of the actor's films, Bono's personal guitar and a Harley Davidson motorcycle autographed by Martin Scorsese and Robert De Niro.
