Eco warrior wannabe Leonardo DiCaprio is back doing what he does best: Fighting for the environment while simultaneously contributing to its demise.

On Wednesday, DiCaprio hosted his annual eco fundraiser gala, which saw an impressive cast of A Listers descend on St Tropez to raise funds for various conservation projects.

'We are the last generation that has a chance to stop climate change before it is too late,' the Oscar winner told the crowd.

DiCaprio was then pictured minutes later talking on the phone and sucking on a vaper, as he was carted across the runway by in a buggy.

There seemed be just a handful of passengers making their way on to the private jet, whose fuel on average produces 21 pounds of carbon dioxide emissions per gallon burned

But his sentiment would be more believable had he not hopped off a helicopter to board a gas guzzling private jet two days later.

And to add insult to injury, he was driven by golf buggy across the airport runway for the short distance between the two.

There seemed be just a handful of passengers making their way on to the private jet, whose fuel on average produces 21 pounds of carbon dioxide emissions per gallon burned.

He also flew in a bevy of models for the occasion and stuck them on a luxury 300ft yacht.

Critics will be quick to note that the actor's private jet trips undermine his moral authority to preach reducing carbon emissions.

But perhaps he is hoping this will be offset by the almost $45 million that was raised to support The Leonardo DiCaprio Foundation Annual Gala To Fund Climate And Biodiversity Projects.

The black-tie fundraiser held in a French vineyard was attended by do-gooder Bono, famous receiver of dodgy diamonds Naomi Campbell, and a smattering of other party-hard pals.

In a speech that heralded the start of the lavish affair, he told the star-studded crowd: 'While we are the first generation that has the technology, the scientific knowledge and the global will to build a truly sustainable economic future for all of humanity—we are the last generation that has a chance to stop climate change before it is too late.'

His intentions may be good, but his unashamed weakness for luxury travel does him little favors if he genuinely wishes to be the savior of Planet Earth.

DiCaprio took a private jet twice in May 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 in Cannes during the May Film Festival.

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 the next 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.

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.

DiCaprio was also 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.
