Hollywood actor, Leonardo DiCaprio, opened a UN climate change summit today by urging world leaders to crack down on polluters and ‘put a price tag on carbon emissions.’ But the 39-year-old Hollywood star’s own jetset lifestyle reveals a double-standard on the issue of climate change. Even if he flew on a commercial jet for all of flights, his carbon footprint so far in 2014 would be a minimum of 40million metric tons, more than twice the average American output. The $220million A-lister is known to charter private jets (bottom left). He spent much of the summer on the 482ft yacht Topaz (top left). DiCaprio owns two properties, including an apartment in New York (top right) and a mansion in Hollywood (bottom right).
