Charles and Camilla and ten staff headed off to Europe last weekend in a private jet to tell everyone else how they need to pull their belts in and stop emitting so much gas.

According to experts from the Carbon Managers company, which carries out environmental audits, the aircraft’s four European flights over 2,200 miles will leave a carbon footprint of 52.95 tons – nearly five times the average person’s 11-ton footprint for an entire year.

Fortunately for the world, Prince Charles’ profligacy has largely been offset by the generosity of Sydney residents and businesses, who this afternoon had another Earth Hour.

OK, so it was a power outage. Whatever. It’s still good for the planet, right?
