While tonight in the U.S. we "spring forward" one hour for Daylight Savings Time... three weeks from tonight, you can take another simple action:

On March 29, 2008, we're asking you--and millions of others--to switch off the lights for one hour during Earth Hour.

What is Earth Hour?
Earth Hour is a global event created to symbolize that each of us, working together, can make a positive impact on climate change--no matter who we are or where we live. Starting at 8 pm local time on March 29, 2008, individuals, communities and businesses will "turn off the lights" in cities around the world for one hour. This simple act will not only heighten awareness of the impacts of climate change on our world, but also inspire individuals and businesses to take practical action to reduce their own carbon footprint.

San Francisco's Golden Gate Bridge will be going dark for Earth Hour

Where will the lights go off?
Everyone around the world is encouraged to be involved and shut the lights off in their homes and businesses. Major participation is planned in 25 cities around the world, on six continents. Four Earth Hour flagship cities in the U.S.--Chicago, Atlanta, Phoenix and San Francisco--are leading the way. Other participating U.S. cities include Denver, Miami and Charlotte.

What can I do?
1. Sign up to participate in Earth Hour.
Pledge to turn off your lights from 8 - 9 pm on Saturday, March 29, 2008. During that hour, replace old light bulbs with energy-efficient compact fluorescent bulbs (CFLs) and commit to reducing energy consumption in the year ahead.

2. Tell your friends about Earth Hour.
Share this message with your friends and family to encourage them to join with you (and millions of others) in support of Earth Hour.

Thank you for switching your lights off and making a statement for the Earth.

Sincerely yours,

Richard Moss
Managing Director and Vice President, Climate Change
