Four climate protesters have scaled Melbourne's famous Young & Jackson hotel, hanging a 23-metre long banner from the building. The banner covering the giant “Time Square” electronic sign on top of the hotel reads “No more climate back flips - Switch Off Hazelwood.”

The World Environment Day protest aims to highlight Kevin Rudd's policy reversals on climate change and is part of the campaign to replace Hazelwood power station with renewable energy.

Spokesperson for the group Ellen Roberts said, “After comprehensively failing to fulfil his electoral mandate to take action on climate change, Kevin Rudd is under pressure to finally deliver. It's time we closed Hazelwood - Australia's dirtiest coal-fired power station”

“Community support for replacing Hazelwood is growing as the public realises that Kevin Rudd and John Brumby have failed to deliver on climate. Climate and environment groups will continue our campaign on Hazelwood all the way to the State Election.

Hazelwood power station is one of the dirtiest power stations in the developed world and produces 15% of Victoria's carbon pollution.
