Leonardo DiCaprio takes a private jet to pick up an environmental award in New York... before flying back for a star-studded gala in France

Leonardo DiCaprio took a private jet twice to pick up an environmental award in New York - before flying back to a glitzy gala in France.

The actor and environmentalist, 41, was spotted this week in Cannes, where the Film Festival is currently underway.

But he left the French Riviera for a brief trip to New York City, where he collected an honor at the Riverkeeper Fishermen's Ball on Wednesday, Page Six reported.

He then hopped back on another private jet to attend the amfAR gala in Antibes, about eight miles from Cannes, just 24 hours later.

DiCaprio has been accused of hypocrisy as he can often be heard preaching about saving the environment and fighting climate change - while taking private jets to do so.

The actor, who turned his Oscars speech into a pressing warning against climate change in February, accumulated more than 8,000 of air travel in just a couple of days.

He was seen in Cannes earlier this week, enjoying some downtime in his hotel and dancing at the Gotha club on Monday.

But he flew back to New York City on Wednesday to attend the Riverkeeper Fishermen’s Ball.

The environmental group picked DiCaprio and Ralph Lauren as this year's two honorees.

Andy Cohen hosted the event at Chelsea Piers, while Sting performed and Robert De Niro introduced a short film by fellows of the Tribeca Film Institute.

Robert F Kennedy Jr, the group's chief prosecuting attorney, also attended the ball.

DiCaprio posted a picture of the event on Instagram - on which he describes himself as an 'actor and environmentalist - and wrote in the caption: 'It was an honor to join Ralph Lauren, Robert De Niro, Robert F Kennedy Jr & more to support Riverkeeper’s critical work to create and protect a healthier future for millions of people.'

The actor (pictured stepping out of a private jet in 2013 in Nice, France) took six private jets in just six weeks in 2014, flying between Los Angeles, New York and Las Vegas according to emails leaked from Sony

His foundation, which pledged $15 million to improving the environment in January at the World Economic Forum, announced plans to give a $100,000 grant to Riverkeeper.

But DiCaprio was back in France just 24 hours later for amfAR’s 2016 Cinema Against AIDS Gala at the Hotel du Cap-Eden-Roc in Antibes, not far from Cannes.

He raised $336,000 for the fundraiser by auctioning off a week-long stay at his Palm Springs residence - even though he won't be there when the guests arrive.

The actor, who said climate change was the 'most urgent threat facing our entire species' during his Oscar acceptance speech, has been repeatedly criticized for his use of jets and yachts.

Environmental analyst Robert Rapier told Page Six DiCaprio's lifestyle 'diminishes his moral authority to lecture others on reducing their own carbon emissions.

Rapier added: '[He] demonstrates exactly why our consumption of fossil fuels continues to grow. It’s because everyone loves the combination of cost and convenience they offer. 

'Alternatives usually require sacrifice of one form or another... Everybody says, "I’ve got a good reason for consuming what I consume".'

 The amount of fuel burnt by a private jet depends on the size and model of the plane. Larger aircraft require more fuel, and more recent models tend to burn less fuel per hour than older ones.

A light jet can go through 77 to 239 gallons of fuel per hour according to Sherpareport, whereas a long-range jet will burn between 358 and 672 gallons of fuel during the same time.

The Cessna Citation Excel, a popular corporate jet with a medium size, would need 800 gallons of fuel for a long-haul flight with four passengers on board, Slate reported in 2008. 

DiCaprio was slammed last year by RadarOnline, which reported he had taken six private jets in just six weeks in 2014.

Emails leaked from Sony at the time stated DiCaprio had accumulated more than $200,000 worth of private jet travel between April and May, taking two round trips from Los Angeles to New York, then one from Los Angeles to Las Vegas.

The actor's private jet trips undermine his moral authority to preach reducing carbon emissions, environmental analyst Robert Rapier told Page Six.

DiCaprio's rep didn't comment to the website. 

But a source close to the star said DiCaprio didn't fly the plane on his own or organize his own flights, but instead 'hitched a ride' with someone doing the same itinerary.

'Hitching a ride was the only way he could make it in time for both events,' the source told Page Six.

The actor was also criticized in July last year when he spent a week sailing around the Mediterranean on his luxury yacht - right after receiving another award for his environmental work.

Prince Albert II of Monaco gave DiCaprio the Mediation Division award in Monte Carlo, just before the actor hosted his foundation's second fundraiser in the south of France, raising $40 million.

The actor was then spotted traveling on his personal yacht in various places around the Mediterranean - including Saint Tropez in France and Sardinia in Italy.

A source close to the Oscar winner said he 'hitched a ride' to Cannes rather than chartering his own flight.
