He's a high profile advocate of environmental causes, believes the world must act now to combat the effects of global climate change and is producing documentaries about endangered species.

But accusations of hypocrisy have also dogged Hollywood star Leonardo DiCaprio, 40, with detractors accusing him of not practicing what he preaches.

Now with RadarOnline reporting Friday that he took six private jet flights in just six weeks last year, it may prove hard for the actor to justify the need to avail himself of more than $200,000 worth of private travel between LA and New York in such a short period of time.

Wikileaks published the complete Sony leak including a searchable database for the 173,132 emails and 30,287 separate documents taken from the studio's servers last November.

It's been claimed the hack was a warning to the studio not to release the film The Interview, about an assassination attempt on North Korean leader Kim Jong-Un.

RadarOnline said that several documents relating to Sony corporate travel records show the Titanic and Wolf Of Wall Street star took six private roundtrip private jet flights during April and May 2014.

Each time the studio picked up the cost of the plane as well as catering and car service at the departure and arrival destinations.

The day before Wikileaks published the collection of hacked documents, DiCaprio tweeted that the fourth and final video that he narrated for the Green World Rising website is now online.

Green World Rising is funded through the Leonardo DiCaprio Foundation and one of the things it suggests visitors to the website do is 'Lighten your carbon load.'

There's even a handy carbon calculator so people can see just how much their way of life is impacting the planet and therefore can take 'meaningful action' to reduce their carbon footprint, at home, at work and at school.

Ironically, four months later, the actor was back in New York to accept a Clinton Global Citizen Award for his environmental preservation efforts.

In his acceptance speech, DiCaprio stressed that more needed to be done.

'Now what does that say about us that we care so deeply about growing our own economy and yet do so little to protect our only home?' he said at the event on September 22, 2014.

DailyMail.com reached out to DiCaprio's people regarding the latest revelations but so far there's been no public comment from the star or his representatives.
