Actor Leonardo DiCaprio rocked a fuller-than-ever beard and a slicked-back man bun look as he accepted his Clinton Global Citizen Award here for his environmental work.

DiCaprio was presented the award by World Wildlife Fund CEO Carter Roberts Sunday, reports usmagazine.com.

The "Titanic" star urged the public to keep environmental concerns in their minds.

"Climate change is compromising the very livability of our planet," he said.

"Less than three percent of all philanthropic giving goes toward protecting and preserving our environment," he explained, before urging people "to put environmental issues at the forefront of the human agenda."

Earlier in the day, the actor participated in the People's Climate Change march, alongside fellow environmental activists Edward Norton, Mark Ruffalo, Sting and Evangeline Lilly.

Eva Longoria, Seth Meyers, Randy Jackson and Chelsea Clinton also attended the award ceremony.
