New York — Leonardo DiCaprio is upping the ante in his environmental philanthropy: His foundation has announced $15.6m in grants for conservation efforts.

It's the largest series of donations by the Leonardo DiCaprio Foundation . It boasts donations of more than $59m since it was founded in 1998.

DiCaprio has lobbied world leaders about climate change, protecting wildlife and more. In a statement released on Wednesday, the Oscar-winning actor said he was increasing the level of grants "to help solve some of the world's most pressing environmental challenges."

He also appointed Terry Tamminen as the foundation's CEO. He was once secretary of California's Environmental Protection Agency.
