Uniting People to Protect the Planet
Earth Hour 2013: Saturday, March 23 - 8:30pm
In support of Earth Hour, the Space Needle will join millions of individuals, businesses and landmarks around the world by turning off its exterior lights this Saturday between 8:30pm and 9:30pm. The aircraft beacon at the top of the Space Needle, interior lights and lighting within the core will remain on.
Earth Hour began in Sydney, Australia as a symbolic event to reduce greenhouse gasses and has evolved into a global movement. If the greenhouse reduction achieved in Sydney during Earth Hour was sustained for a year, it would be equivalent to taking 48,616 cars off the road for a year.
