Leonardo DiCaprio is the greenest of green celebrities. 

The actor was a driving force behind “The 11th Hour,” a 2007 documentary sounding the alarm about global warming, deforestation and other environmental causes. He drives a hybrid car, warns us about climate change and typically eschews chartered jets to minimize his carbon footprint.

But when 2013 came calling, DiCaprio decided to live it up like the A-list star he is, leaving an impressive carbon footprint in his wake.

Leo DiCaprio and his “Wolf of Wall Street” co-star Jonah Hill racked up some impressive air miles for their New Year’s celebrations — cheering in the New Year in both Sydney and Vegas. The actors were spotted partying on a boat with a group of attractive bikini-clad women while cruising Sydney Harbor on Saturday. The pair flew from Australia to Vegas on a chartered 747 along with stars including Jamie FoxxKevin Connolly and Leo’s latest love, Margot Robbie. A source tells us, “They partied at Marquee Star Lounge Sydney and left at 1 a.m. Australia time, flew 13 hours to Vegas, arriving at 10 p.m. to Vegas, and went to Lavo to watch the fireworks.”
