A squadron of 1,700 private jets are rumbling into Davos, Switzerland, this week to discuss global warming and other issues as the annual World Economic Forum gets underway.

The influx of private jets is so great, the Swiss Armed Forces has been forced to open up a military air base for the first time ever to absorb all the super rich flying their private jets into the event, reports Newsweek.

“Decision-makers meeting in Davos must focus on ways to reduce climate risk while building more efficient, cleaner, and lower-carbon economies,” former Mexican president Felipe Calderon told USA Today.

Davos, which has become a playground of sorts for the global elite, is expected to feature at least 40 heads of state and 2,500 top business executives. Former Vice President-turned-carbon billionaire Al Gore and rapper Pharrell Williams will be there as well; each plans to discuss global warming and recycling respectively.

Another big theme of the mega-rich confab will be combating “income inequality” and how the world’s rich can pay their fair share to reduce the gap between top earners and the lower class. Admission price for Davos: roughly $40,000 a ticket.

The World Economic Forum will also feature discussions on gender equality and opportunities for women. According to the World Economic Forum’s own statistics, just 17% of all 2015 participants are women.

The 45th World Economic Forum meeting begins on Wednesday and runs through Saturday.
